## What?
This test currently causes others to fail. Trying adding a skip for this
to see if other issues come up before porting it to be isolated:
```
● Test suite failed to run\n\n The name `source-map` was looked up in the Haste module map. It cannot be resolved, because there exists several different files, or packages, that provide a module for that particular name and platform. The platform is generic (no extension). You must delete or exclude files until there remains only one of these:\n\n * `/root/actions-runner/_work/next.js/next.js/packages/next/src/compiled/source-map/package.json` (package)\n * `/root/actions-runner/_work/next.js/next.js/test/integration/app-dir-export/output/standalone/packages/next/dist/compiled/source-map/package.json` (package)\n\n at ModuleMap._assertNoDuplicates (../node_modules/.pnpm/jest-haste-map@29.7.0/node_modules/jest-haste-map/build/ModuleMap.js:189:11)\n

-->
### What?
Adds safe traversal to rewrite `has` items in a certain new
(`isInterceptionRouteRewrite()` added in the v14.2.0 canaries) check to
the rewrite routes.
### Why?
The new check assumed that all `has` arrays had at least one item, when
previously Next.js accepted rewrites with empty `has`. Adding safe
traversal doesn't negatively impact the check, as the check only needs
rewrites with the first item.

### What?
Pass the names of side-effect-free packages specified in `experimental.optimizePackageImports`.
Turbopack counterpart: https://github.com/vercel/turbo/pull/7731
### Why?
Some packages like `@tremor/react` causes a problem without `optimizePackageImports`.
### How?
Closes PACK-2527
### What
Strip the search query for the `urlPathname` passed down to metadata
handling.
### Why
This is because the `urlPathname` from `staticGenerationStore` contains
query, so it will contain `?rsc` query for client navigation, which lead
to the relative path canonical url (e.g. `./`) will have the search
query along with it. This PR is to remove that and make sure always uses
pathname.
Reported by @pacocoursey
Closes NEXT-2963
### What & Why
When an RSC triggers `navigate` after the shell has already been sent to
the client, a meta tag is inserted to signal to the browser it needs to
perform an MPA navigation. This is primarily used for bot user agents,
since we wouldn't have been able to provide a proper redirect status
code (since it occurred after the initial response was sent).
However, the router would trigger a SPA navigation, while the `<meta>`
tag lagged to perform an MPA navigation, resulting in 2 navigations to
the same URL.
### How
When the client side code attempts to handle the redirect, we treat it
like an MPA navigation. This will suspend in render and trigger a
`location.push`/`location.replace` to the targeted URL. As a result,
only one of these navigation events will win.
Fixes#59800Fixes#62463
Closes NEXT-2952
Closes NEXT-2719
When a server action performs a redirect, we currently initiate a `HEAD`
request to the targeted URL to verify if it has a proper RSC response.
If it does, it then invokes a GET and streams the response. This leads
to an extra request to the server which can be costly and poor for
performance. If the `GET` returns an invalid RSC response, we'll discard
the response. The client router will also see the invalid response which
will signal that it needs to perform an MPA navigation to the targeted
URL.

-->
Closes NEXT-2956
### What
Supports partial `get-page-static-info` in turbopack. Since turbopack
doesn't have equivalent place to webpack's ondemandhandler, it uses
turbopack's build time transform rule instead.
As noted, this is partial implementation to pagestatic info as it does
not have existing js side evaluations. Assertions will be added
gradually to ensure regressions, for now having 1 assertion for
getstaticparams.
Closes PACK-2849
### What
When calling `revalidatePath` or `revalidateTag` in a server action for
an intercepted route with dynamic segments, the page would do a full
browser refresh.
### Why
When constructing rewrites for interception routes, the route params
leading up to the interception route are "voided" with a
`__NEXT_EMPTY_PARAM__` demarcation. When it comes time to look up the
values for these dynamic segments, since the params aren't going to be
part of the URL, they get matched via `FlightRouterState`
([ref](d67d658ce7/packages/next/src/server/app-render/app-render.tsx (L153-L201))).
The `shouldProvideFlightRouterState` variable only passes it through for
RSC requests; however, since the server action will perform the action &
return the flight data in a single pass, that means the updated tree
from the server action isn't going to receive the `FlightRouterState`
when constructing the new tree. This means the old tree will have a
`["locale", "en", "d"]` segment, and the new tree from the server action
will have `"[locale]"`. When the router detects this kind of segment
mismatch, it assumes the user navigated to a new root layout, and
triggers an MPA navigation.
### How
This unconditionally provides the `FlightRouterState` to
`makeGetDynamicParamFromSegment` so that it can properly extract dynamic
params for interception routes. We currently enforce interception routes
to be dynamic due to this `FlightRouterState` dependency.
Fixes#59796
Closes NEXT-2079
`applyRouterStatePatchToTree` had been refactored to support the case of
not skipping the `__DEFAULT__` segment, so that `router.refresh` or
revalidating in a server action wouldn't break the router. (More details
in this #59585)
This was a stop-gap and not an ideal solution, as this behavior means
`router.refresh()` would effectively behave like reloading the page,
where "stale" segments (ones that went from `__PAGE__` -> `__DEFAULT__`)
would disappear.
This PR reverts that handling. The next PR in this stack (#63608) adds
handling to refresh "stale" segments as well.
Note: We expect the test case that was added in #59585 to fail here, but
it is re-enabled in the next PR in the stack.
Note 2: #63608 was accidentally merged into this PR, despite being a
separate entry in the stack. As such, I've copied the issues from that
PR into this one so they can be linked. See the notes from that PR for
the refresh fix details.

## What?
Currently `next build` with Turbopack fails to run in certain tests (as
expected), the problem with that is that the `afterAll()` calls assume
the server was started, which doesn't happen when the build fails, and
then causes a timeout that can't be reported if an error happens. This
change ensures the error around `server['__app']` doesn't happen.

### What
Supports root segment config inherit from layout. Currently route
segment config only runs agasint own source, so individual route segment
config works but if the config is set in layout level it is being
ignored. PR introduces root segment and pass into each route if tree
level have a corresponding layout.
Closes PACK-2839
### What
In static generation phase of app page, if there's any case that we're
receiving 3xx/4xx status code from the response, we 're setting it into
the static generation meta now to make sure they're still returning the
same status after build.
### Why
During static generation if there's any 3xx/4xx status code that is set
in the response, we should respect to it, such as the ones caused by
using `notFound()` to mark as 404 response or `redirect` to mark as
`307` response.
Closes NEXT-2895
Fixes#51021Fixes#62228
Recently the serverActionReducer was updated to no longer use React's
thenable type to carry resolution/rejection information. However the
rejection reason was not updated so now when a server action fails we
were rejecting with `undefined` rather than the rejected reason. This
change updates the reject to use the rejection value.
Closes NEXT-2943
This ensures that even if a `loading.js` returns `null`, that we still
render a `Suspense` boundary, as it's perfectly valid to have an empty
fallback.
This was accidentally lost in #62346 -- this brings back the
`hasLoading` prop which will check the loading module itself (rather
than the `ReactNode`) for truthiness, and I've added a test to avoid
another regression.

### What
* Remove the erroring of force-dynamic is not able to use during static
generation
* Export the route segments properly in sitemap conventions
### Why
We discovered this error is showing up when users are using
force-dynamic with generating multi sitemaps.
When you have a dynamic `route /[id]/route.js` , and you have
generateSitemaps defined which is actually using `generateSitemaps`
under the hood , then you set the route to dynamic with `export dynamic
= 'force-dynamic'`.
We should keep the route still as dynamic. `generateStaticParams` is
only for generating the paths, which is static in build time. And the
`force-dynamic` is going to be applied to each generated path.
Closes NEXT-2881
Followup on https://github.com/vercel/next.js/pull/52520 and
https://github.com/vercel/next.js/pull/54014
**Enhancements**
- Removes `--experimental-test-proxy` CLI argument from `next dev` and
`next start`
- Adds a new experimental config option `testProxy?: boolean`
- Instead of throwing an error, return the `originalFetch` response if
the current request context does not contain the `Next-Test-*` HTTP
headers
**Why?**
These changes allow us to write mixed Integration + E2E tests within the
same Playwright process.
```ts
// some-page.spec.ts
test.describe('/some-page', () => {
test('some integration test', async ({ page, next }) => {
// by using the `next` fixture, playwright will send the `Next-Test-*` HTTP headers for
// every request in this test's context.
next.onFetch(...);
await page.goto(...);
await expect(...).toBe('some-mocked-value');
});
test('some e2e test', async ({ page }) => {
// by NOT using the `next` fixture, playwright does not send the `Next-Test-*` HTTP headers
await page.goto(...);
await expect(...).toBe('some-real-value');
});
})
```
Now I can run `next dev` and locally develop my App Router pages AND run
my Playwright tests against instead of having to,
- run `next dev` to locally develop my change
- ctrl+c to kill server
- run `next dev --experimental-test-proxy` to locally run my integration
tests

This ensures that the instrumentation hook for Node.js will run
immediately during `next start` instead of waiting for the first request
like does it `next dev`.
However, if there is a separate instrumentation hook for Edge, that will
still be lazy evaluated and wait until the first request.

### What
This PR implements runtime warning for dynamic codes (`eval`,
`Function`...) in edge runtime. Webpack uses middleware plugin to
replace / wrap codes, in case of Turbopack we don't have equivalent, so
creating a new transform visitor and run it if the context is edge.
Since sandbox augments global fn (__next_*), transform simply wraps the
expr if it matches to the condition.

Fixes PACK-2522

### What
Actions that revalidate the router state by kicking off a refetch (such
as `router.refresh()` or dev fast refresh) would incorrectly trigger an
interception route if one matched the current URL, or in the case of
already being on an intercepted route, would trigger the full detail
page instead.
### Why
Interception rewrites use the `nextUrl` header to determine if the
requested path should be rewritten to a different path. We currently
forward that header indiscriminately, which means that if you were on a
non-intercepted route and called `router.refresh()`, the UI would change
to the intercepted content instead (since it would treat it the same as
a soft-navigation).
### How
This updates various reducers to only forward the `nextUrl` header if
there's an interception route present in the tree. If there is, we want
to refresh its data, rather than the data for the underlying page. The
reverse is also true: if we were on the "full" page, and triggered a
`router.refresh()`, we won't forward `nextUrl` meaning it won't fetch
the interception data.
In order to determine if an interception route is present in the tree, I
had to add a new segment type for dynamic interception routes, as by the
time they reach the client they are stripped of their interception
marker.
**Note: There are a series of bugs related to `router.refresh` with
parallel/interception routes, such as the previous page/slot content
disappearing when triggering a refresh. This does not address all of
those cases, but I'm working through them!**

Closes NEXT-2737
Currently when we generate payloads in app router, the order of RSC
chunks aren't deterministic even if the content stays the same. This
means that any caches that rely on etags for detecting changes in
content aren't able to reliably cache/and avoid invalidating properly.
To avoid this we can manually sort the content before generating the
etag. Eventually this can be fixed upstream in react although that is a
bigger lift so we are doing this for now to alleviate the issue.

### What
Implement webpack's middleware plugin equivalent for webpack, to raise
unsupported error in runtime.

modulereplacer internally provides a virtualsource to call runtime error
logic. Since we already have globally augmented, the virtualsource only
need to take export those into module.
Closes PACK-2789
In #61573, I updated the navigation reducer to request a new prefetch
entry if it's stale. But this has the unintended consequence of making
instant loading states effectively useless after 30s (when the prefetch
would have expired). Blocking navigation and then rendering the loading
state isn't ideal - if we have some loading data in a cache node, we
should re-use it.
Now that #62346 stores loading data in the `CacheNode`, we can copy over
`loading` during a navigation.
This PR repurposes `fillCacheWithDataProperty` which wasn't being used
anywhere, to instead be a utility we can use to programmatically trigger
a lazy fetch on a particular segment path by nulling out it's data while
copying over other properties. We could have used the existing util
as-is, but ideally we only have a single spot where lazy fetching can
happen, which currently is in `LayoutRouter`.
When a stale prefetch entry is detected, rather than applying the data
to the tree, this PR will copy over the `loading` nodes and will
"delete" the data so it can be refetched.

### What?
Now that @phanect added support for ESM PostCSS config files in PR
#63109 (original issue #34448), PostCSS can use ESM config by default.
It needs to use an `.mjs` extension by default because `create-next-app`
scaffolds CommonJS apps by default.
This will also work with ESM projects which have added `"type":
"module"` in their `package.json`
### Why?
1. To convert one more file to ESM
2. To use the modern format
3. To follow other similar migrations that have taken place in the
Next.js codebase (eg. `next.config.mjs`)
### How?
- Change file extensions from `.cjs` to `.mjs` (change similar to PR
#58380)
- Change module format from CommonJS to ESM
- Add type for the config, for users who enable `checkJs: true` in
`tsconfig.json`

script tag cannot be placed under html directly, users reported a case
in #51242 that having `<Script>` under html will cause hydration error,
this will display the React hydration error related warning of bad usage
for it.
You will see this warning in dev overlay instead of displaying nothing
```
In HTML, <script> cannot be a child of <html>.
This will cause a hydration error.
```
Added two other react warnings detection patterns as well
* `Warning: In HTML, text nodes cannot be a child of <%s>.\nThis will
cause a hydration error.',`
* `Warning: In HTML, whitespace text nodes cann...`
But tested they're not generating hydration errors, only warnings in
console, so we don't need to have tests for them.
Closes NEXT-2835
### What?
This fixes more CSS ordering issues with production and webpack dev.
* CSS Modules must not be side effect free as side effect free modules
are per definition order independent which is not true for CSS
* fix order of iterating module references
* disable splitChunks for CSS
* special chunking for CSS with loose and strict mode
* more test cases
Closes PACK-2709
### What?
* Allow to apply webpack loaders depending on "conditions".
* add a few next specific conditions depending on context type
### Why?

Turbopack HMR: Log when more errors cause full page reload

### What?
Apply same patch as https://github.com/vercel/next.js/pull/62983 for
`pages/_app.js`
### Why?
To make turbopack match behavior of webpack mode, and make the test
passs
### How?
Closes PACK-2407
This changes how loading components are provided to `LayoutRouter` to instead be part of the `CacheNode`. This makes it so that we can copy it over/expire it in a similar way to the `data` property on a `CacheNode`. Consequently, this fixes a bug in PPR navigations, where 2 different loading states (the prefetched one, followed by the updated one) might be displayed upon navigating.
Note: This disables a PPR test that asserts the loading data gets expired after 5 minutes. As implemented, the loading data will remain cached for a particular segment.

This ensures we properly set the matched header when applying a
middleware skip optimization so that the client router has enough
context to finish resolving the dynamic route params.

Closes NEXT-2803
This PR stabilizes an experimental feature that was added in a previous
PR https://github.com/vercel/next.js/pull/50470
It allows the user to set `deploymentId` in `next.config.js`, which is a
unique identifier for a deployment that will be included in each
request's query string or header.
This PR is easier to review with whitespace hidden:
https://github.com/vercel/next.js/pull/63198/files?w=1
Closes NEXT-2789
### What
This is stopgap substitution to webpack's wellknownerrorsplugin. When
webpack compilation hits known errors kind it emits compilation errors
into cli (and dev overlay both) while turbopack currently only emits
into error overlay. PR simply detects if given issue is well known, and
then logs into std.
Probably a long term there should be proper wiring instead; but for now
this allows to make few things work out of the box.
Closes PACK-2727
### What
Use SWC to check invalid client hooks of `next/navigation` imports in
server components.
Follow up of #62456
Remove the runtime error APIs for `next/navigation` rsc version.
Add `next/navigation` react-server version alias in turbopack.
This PR also refactored the invalid server layer APIs detection into a
map, where key is import path and value is an array of client APIs.
During the traversing we will get the import source easily, this makes
extending the logic much easier
### Why
Previously we're using the runtime error to check it, but it has to run
first then the error will be thrown. If we error first in build time
with this check it's much faster and we this align on both side between
webpack and turbopack.
### What
When a route handler uses an API that opts it into dynamic rendering
(such as `no-store` on a fetch), and also specifies a `revalidate` time,
the `revalidate` time is ignored and route is treated as fully static.
### Why
`revalidate: 0` and `revalidate: false` have different semantic
meanings: `false` essentially means cache forever, whereas `0` means
it's dynamic. Since `0` is also falsey, the code we have to fallback
with a default `revalidate` value for route handlers is incorrectly not
marking the route as dynamic, and as a result, caching the route without
an expiration time.
### How
This updates the fallback handling for app routes respect a revalidation
value of `0`, so that the page can properly be marked dynamic.
### Test Explanation
This adds 2 new routes handlers: both have a revalidation time specified
& use `no-store` on a fetch, but only one of them specifies `export
const dynamic = 'force-static'`. The one that doesn't specify
`force-static` is correctly omitted from the prerender manifest. The one
that is `force-static` is correctly in the prerender manifest with the
right expiration time. An additional test case was added to verify that
this data refreshes after the specified interval.
Closes NEXT-2764
Addresses some feedback in #62821. This will re-allow implementations
like:
```js
'use server'
export const f = wrapper(async () => {})
```
Where `wrapper` creates a sync function that returns a promise. Although
it will still be silently converted to an async function under the hood.
Closes NEXT-2790
### What?

needed for og-image.

Closes PACK-2725
### What
This PR completes resolve plugin for the invalid import assertion, for
the server-only in client component + styld-jsx in server components.
Closes PACK-2707
This ensures we properly catch/handle `generateMetadata` errors during
eager evaluating of nested `generateMetadata` functions in the tree.
Previously if we eager evaluated a child metadata function that threw an
error e.g. `notFound()` and but the parent metadata function took longer
the thrown error would be an unhandled rejection causing the process to
crash depending on the environment.
Fixes: NEXT-2588
Closes NEXT-2786
## What?
Follow-up to #63128
`JSON.stringify(undefined)` ends up with the value `undefined`. However
for Webpack/Turbopack to correctly inject `undefined` into the code it
has to be the string `'undefined'`. This change ensures the
serialization takes into account that case.

### What
When triggering an MPA navigation (also commonly referred to as a "hard
navigation"), and then restoring the previous page via the browser's
bfcache, subsequent requests to the same link wouldn't navigate until
reloading the page or performing a different navigation.
### Why
MPA navigations in app router are handled in a fairly unconventional
way: the router state is updated with an indication that an external URL
was clicked, and once the router sees the pending navigation, it kicks
off a `location.replace` or `location.push` with the specified URL **in
render**. The router then suspends indefinitely to prevent committing
the render. However, the router will only make the `replace`/`push`
request if there's not already a pending navigation to that same URL.
The pending check is needed to avoid continuously calling
`push`/`replace` when unrelated router state changes occur (for example,
if I hover over a link and trigger a prefetch action and the router
re-renders, it shouldn't make another `location.push` call to the same
URL that's pending)
However, the source of the bug is that the variable that holds this
pending state is also restored by the browser's cache, since it takes a
snapshot prior to exiting the page. This means that when clicking the
browser back button, `pendingMpaPath` would still be set to the URL we
just came from. When clicking the link again, it would see that the
requested URL is the same as the pending URL, and not perform any
history actions.
### How
This clears the pending value when the router is restored from bfcache.

### What?
This fixes a special case where rewrites wouldn't work when resuming a
dynamic page.
### Why?
Previously, as routes would direct-match against entries in the cache,
this takes the `x-matched-path` as the source of truth for these
requests if the `x-now-route-matches` header is not present.
### What?
make sure that we don't error for dynamic requests on server side.
It will throw at runtime when using a dynamic request.
### Why?
Not all packages are fully bundler compatible, but still work when only
using the parts that work. We don't want to block users from using them
by having an hard compile error.

The value `undefined` can be saved to the incremental cache as
`undefined` (`JSON.stringify(undefined)`) with no errors, but when
retrieving it, we attempt to parse it as JSON using
`JSON.parse(undefined)`. This throws an error. We should instead
deserialize `undefined` as `undefined` when retrieving.

### What
Exclude the cases like external urls and relative urls with query from
appending trailing slash when it's needed.
The process is:
- If it's a uncertain string path (relative url, could start with `'./'`
or `/`), convert to relative that starts with `/`;
- then we covert the url (string or URL) to string url
- We do the check if we need to append the trailing slash
### Why
In #62109 we added functionality that can only append trailing slash
when we appended trailing slash to some metadata url like `canonical`
url and open graph url when the config is enabled.
For urls with queries, the trailing slash can also be omitted.
For the external urls (different origin comparing to `metadataBase`) we
don't need to append trailing slash as they're not the same web app.

Closes NEXT-2695
An iteration of #62359, this uses the module-local flag instead of a

Closes PACK-2690
The "Compiled" HMR log is emitted as follows:
> Compiled in 54ms
When running this string through the matcher, we get:
```
> const matches = "Compiled in 54ms".match(/Compiled.*? in ([\d.]{1,})\s?(?:s|ms)/i)
console.log(matches[1]); // 54
```
We correctly assign `compileTime` to `matches[1]`. However, we then
assign `compileTimeMs` to `parseFloat(compileTime[1])`. This is
definitely an error, as `compileTime[1]` would be `4` in the above
example.
This means that if the compilation time takes less than a single digit
value, it'd be coerced to NaN.

### What
* Move missing html tags error into error overlay, from outside we don't
have to manually determine when to render a dummy component with runtime
missing tag error or error overlay.
* Add brackets `<>` to the html tags in the error
### Why
In #62815, we're having throwing an missing required error, this will
trigger another runtime error. Then when error overlay caught it through
error event listener, it will render it as an unhandled runtime error:
You will see the below message in the overlay.
```
Unhandled Runtime Error
Error: The following tas are missing...
[Error stack]
```
This error message will bring a message that the error is happened on
client during runtime, but actually we already know that is a user side
mistake which doesn't have a error trace. This couldn't hmr as you fix
the error as well.
This PR moves the rendering into error overlay that we're aware of the
errors and can render the correct html on client, with the `html` tag
attached with error id and `body` wrapping the error overlay. We tell
overlay that there're missing tags through props, let it handle
everything inside.
It can also hmr once you fix the error. One drawback is that when you
re-introduce the error, it might trigger react DOM updates exception
(`Failed to execute 'removeChild' on 'Node': The node to be removed is
not a child of this node.`) instead of the "missing tags" message again.
Besides that the HMR works properly.

### What
I noticed the font manifest generated by Turbopack was always empty.
Debugging showed that the path to the client_root was always incorrect

original path.

Closes NEXT-2691
As mentioned in the new-added error messages, and the [linked
resources](https://react.dev/reference/react/use-server#:~:text=Because%20the%20underlying%20network%20calls%20are%20always%20asynchronous%2C%20%27use%20server%27%20can%20only%20be%20used%20on%20async%20functions.):
> Because the underlying network calls are always asynchronous, 'use
server' can only be used on async functions.
> https://react.dev/reference/react/use-server
It's a requirement that only async functions are allowed to be exported
and annotated with `'use server'`. Currently, we already have compiler
check so this will already error:
```js
'use server'
export function foo () {} // missing async
```
However, since exported values can be very dynamic the compiler can't
catch all mistakes like that. We also have a runtime check for all
exports in a `'use server'` function, but it only covers `typeof value
=== 'function'`.
This PR adds a stricter check for "use server" annotated values to also
make sure they're async functions (`value.constructor.name ===
'AsyncFunction'`).
That said, there are still cases like synchronously returning a promise
to make a function "async", but it's still very different by definition.
For example:
```js
const f = async () => { throw 1; return 1 }
const g = () => { throw 1; return Promise.resolve(1) }
```
Where `g()` can be synchronously caught (`try { g() } catch {}`) but
`f()` can't even if they have the same types. If we allow `g` to be a
Server Action, this behavior is no longer always true but depending on
where it's called (server or client).
Closes#62727.
### What?
* upgrades turbopack for `getResolve` in webpack loaders
* add missing resolve-url-loader to turbopack for full sass support
Closes PACK-2634
Previously, errors shown in the error overlay, these stir were left
untraced through source maps.

Closes PACK-2608
## Description
Refactor the [Next.js
CLI](https://nextjs.org/docs/app/api-reference/next-cli) to use
[commander](https://github.com/tj/commander.js) instead of
[arg](https://github.com/vercel/arg).
## Why?
- Auto-generated, properly formatted help command + output. With `arg`,
much of the help commands were manually added via a single
`console.log`, causing deviations over time.
- Ergonomic, ease of adding new subcommands and rules
## Breaking Changes
- Update the experimental `next experimental-compile` and `next
experimental-generate` build commands in favor of `next build
--experimental-build-mode=compile/generate`

## What?
Working on fixing `test/e2e/conflicting-app-page-error`, this adds a
compiler error for the case where App Router routes conflict with Pages
Router routes. It's not 1:1 the same error as in webpack because in the
webpack version we hijacked the App Router resolving logic to assume
there's a certain set of paths, where Turbopack has the full route to
route tree resolving implementation which doesn't assume there's a
single page that can be resolved.
The tests are updated to reflect this change.

## What?
Migrates the Sass support tests from `test/integration` (legacy test
suite) to `test/e2e`, this way all these tests run against both
development and production, whereas previously most of them would only
run against production.
This is helpful as it ensures the tests are running against Turbopack
too, which is highlighting some missing features in Sass support for
Turbopack.
I've had to rewrite most of the tests to check against the actual
rendered output in the browser instead of CSS output in the `.next`
folder, the majority of these now run regardless of implementation
details.

### What
Keep improving the hydration erros. Currently we divide the hydration
mismatch types into two categories, html tag mismatch and text mismatch.
We're displaying the mismatched text content between server and client
here since we have it in the component stack and warnings.
We've already made some improvements in #62590 , here we carry on
improving the highlited text into red and bold that is much easier for
you to spot on.
This updated a few long snapshots that we could collapse and show only
the text content difference instead of all the component stack.
### Screenshots

#### Large content mismatch
### Why
I was intended to bring a html diff between server and client html
content but turns out the diff result could be giant and not ideal due
to few reasons. So we switched to the path of leveraging component stack
and mismatch contents.
React reordering the tags after hydration. For instance the `script` or
`link` tags could be hoist by React Float, so the lines of html is are
to preserved. so the diff is hard to be super accurate unless your
mismatch is small. If you're mismatch a component with rich html
content, it could be a pretty large diff.
Another case is if you have a bad nesting html like `<p> ...<span>...
<p>my text</p> ...</span>... <p>` where there're many span in between,
the final different could also be hudge as browser will close the first
`<p>` tag and the rest content will go into the diff. Hence we're going
with the component and text content diff.
Closes NEXT-2645
### What?
We now keep track of all client assets emitted for each route in
`ClientAssetMapper` and remove all issues associated with them when a
route get deleted.

reported by Turbopack but Next.js didn't show it, which #62528 resolved.
This PR changes the handling for the not-found handling to be consistent
between development and build, which ensures that the "special" page no
longer conflicts with app/not-found/page.js.

### What?
### Why?
### How?
Closes NEXT-
Fixes #
-->
### What?
Do not fail when `useSelectedLayoutSegment` or
`useSelectedLayoutSegments` APIs are called in the Pages Router.
### Why?
This makes migration easier and creates consistency with our other App
Router-specific APIs that inherit the same behavior.
### How?
Similar to #47490, we return `null` if there is no Layout context
(indicating being in Pages Router)
Types are also overridden in the navigation compact module declaration
which kicks in during start to correct the types if we detect a `pages/`
directory.
Note to reviewer: #47490 didn't add a test, so I added one top-level,
let me know if you have a better suggestion for placing.

### What
When you have bad nesting html in your React code, React wil raise
hydration error since the browser html parser might parse it to sth else
different comparing to server html on client. Previously we're display
only the warning in the error description in dev overlay.
Now we introduced another format of displaying pesudo html that
representing your code, with highlighting the html tag that causes the
error. Since React might gives you the whole component stack of React
tree, so we also introduced a way that can collapse the error.
#### Example
https://github.com/vercel/next.js/assets/4800338/622122d6-4d2e-4c8e-95e8-4864343e478b
### Why
The reason we added this is that even we show the html diff, it could
super large due to React ordering the html on client, so the mismatch
might be a lot. The idea here is similar to what you saw when you passed
down a bad event handler into server component, we displayed a pesudo
html as it could hit your mind faster than just seeing the warning. The
best way is to display the source code, but before we can show the
source, getting component stack display as pseudo html instead of here
could be more helpful.

### Problem
We've identified a bug within Next.js's pages router when utilizing the
shallow routing API, specifically when invoking `router.push` with the
`{ shallow: true }` option, like so:
```javascript
router.push('/?counter=10', undefined, { shallow: true });
```
Shallow routing is designed to update the URL without running data
fetching methods such as getServerSideProps, getStaticProps, or
getInitialProps. However, a side effect of this process is that it skips
the clean-up of the cancelHandler. This leads to router error events
being fired erroneously, causing confusion and potential stability
issues, as the system behaves as if an error occurred when, in fact,
none did.
### Solution
This PR addresses the issue by modifying the shallow routing logic to
also skip the creation of the cancelHandler. Given that shallow routing
operations are synchronous and do not involve data fetching or other
asynchronous tasks that might need to be canceled, the cancelHandler is
unnecessary in this context.

### What?
generateSitemaps function returns a 404 for /sitemap/[id].xml in
production
### Why?
While finding the correct sitemap partition from the array, we check the
param against the id. Which works in dev because id and param are both
without trailing .xml. But it fails in production as param has a
trailing .xml (/sitemap/[id] works in production because it falls back
to dynamic loading and param and id are both without .xml)
### How?
If we are in production environment, check the id with a trailing .xml
because that's whats returned from generateStaticParams, an array of
__metadata_id__ with trailing .xml

This moves the locale redirect handling out of `base-server` as it
shouldn't be handled here and should be at the routing level. This
avoids the duplicate handling with middleware that causes the incorrect
detection/infinite looping. Test case from separate PR was carried over

### What
Change from processing the file with `next-metatdata-route-loader`
directly into passing the file as loader query, and leave an empty
resource file for it. This will resolve the error that users were seeing
with `manifest.json` convention.
```
Import trace for requested module:
../../../../packages/next/dist/build/webpack/loaders/next-metadata-route-loader.js?page=%2Fmanifest.jso
n%2Froute&isDynamic=0!./app/manifest.json?__next_metadata_route__
getStaticAssetRouteCode page /manifest.json/route this.resourcePath /Users/huozhi/workspace/next.js/tes
t/e2e/app-dir/metadata-json-manifest/app/manifest.json
```
### Why
I looked at the loader process that the final resource processed by
webpack is `json!next-metadata-route-loader...`, which means the builtin
json loader processing json file after the metadata route loader. I
didn't get chance to solve the ordering issue, so I changed the
resourcePath to empty "", and pass the file path as query into the
loader to avoid json-loader processing it after transpilation.
Fixes#59923
Closes NEXT-2630

This ensures our dynamic routes that have the same specificity as
`_next/static/:path*` don't get matched unexpectedly when the
`_next/static` asset doesn't exist. We were holding off on making this
change explicit due to compatibility concerns but these are no longer a
concern and the unexpected matching is more of a concern.

### What
Fixes `redirect()` call under suspense boundary, redirect url should
include the `basePath` in the url.
### Why
`redirect()` under suspense boundaries will go through server html
insertion, which is being used every time by suspense boundary resolved,
new errors will triggered from SSR streaming. It was missing before.
Fixes NEXT-2615

### What?
We should treat the warning for CSR bailout the same as the hard-error,
and show the stack trace for either case.
### Why?
It might be useful to track down the source of this warning.
### How?
We have the stack info already, but we only showed it during the error
logging. We should show it for warnings too.
This is similar to #61200
Closes NEXT-2624
Addresses #57066
Currently, a user running `next start` on an un-built Next.js project
receives a confusing uncaught error before the process just ends:
```
▲ Next.js 14.1.0
- Local: http://localhost:3000
[Error: ENOENT: no such file or directory, open '/home/flotwig/src/project/.next/BUILD_ID'] {
errno: -2,
code: 'ENOENT',
syscall: 'open',
path: '/home/flotwig/src/project/.next/BUILD_ID'
}
```
In my case, I ran into this because I had not worked with Next.js for a
while, and I forgot that `next dev` was used for local development, not
`next start`. I believe many of the confused users in #57066 are making
a similar mistake and not realizing it, due to the error message.
This PR catches an `ENOENT` when reading `BUILD_ID` and suggests that
the user `next build` or `next dev` to remove this friction point:
```
▲ Next.js 14.1.1-canary.69
- Local: http://localhost:3000

```
A few things probably need to be resolved before this PR can merge, I
would appreciate any input from Next.js maintainers.
- [x] Is this the best place to catch this? I am not familiar with the
Next.js codebase, so I just caught this in the most obvious way.
- [x] Can the error message be improved?
- [x] Add a test for the error in `test/development`

### What
When the popstate action is fired (as is the case in a browser back
button), if the page you're going back to has missing cache node data,
the router will crash.
### Why
Almost all router actions will suspend at the app-router level with the
exception of `ACTION_RESTORE`. This was to address an issue where
suspending in the router would add enough delay for browser scroll
restoration behavior not to work.
As a result, when going back to the page with missing data, app-router
wouldn't suspend but layout-router would suspend on the missing data
while triggering a lazy fetch. We trigger a server-patch with the
applied lazy data, but when React replays the render, it will replay the
branch without the cache node data applied. This results in the router
getting caught in a loop of suspending, applying the cache node,
replaying the branch without the cache node, and eventually crashing due
to an error thrown by React to prevent re-suspending indefinitely.
### How
This adds a property to the cache node to signal if the lazy data has
been resolved. If it has been, we won't call the server patch action
again.
Fixes#61336
Closes NEXT-2438
* Still check if the origin line thrown nodejs errors could still

### What
Introduce a `react-server` export condition of `next/navigation`, which
only take effects in RSC layer. And it will only contain `notFound` and
`redirect` related APIs, which can be shared in both server components
and client components environment. This export excludes those APIs
working with React context which are only working in client components.
### Why
We fixed an issue bad alias for react-server condition of react itself
in
https://github.com/vercel/next.js/pull/61522/files#diff-ecb951c8d26893f6d1e4425a873b399d52346ef63eb90fba79d980cef2fabe8cL35
, this was a good fix. But we found that if you're using edge runtime
with `next/navigation` it will error with bundling that you're attempted
to import some client component hooks such as `useContext` from react.
So we introduced a `react-server` version of `next/navigation` that
doesn't interoplate with any client hooks, can we'll bundle that one
instead of original `next/navigation` when you're using it in server
components or app routes.
Closes NEXT-2583

With Server Actions, a module-level encryption can happen when you do:
```js
function wrapAction(value) {
return async function () {
'use server'
console.log(value)
}
}
const action = wrapAction('some-module-level-encryption-value')
```
...as that action will be created when requiring this module, and it
contains an encrypted argument from its closure (`value`). This
currently throws an error during build:
```
Error: Missing manifest for Server Actions. This is a bug in Next.js

```
Because during module require phase, the encryption logic can't run as
it doesn't have Server/Client references available yet (which are set
during the rendering phase).
Since both references are global singletons to the server and are
already loaded early, this fix makes sure that they're registered via
`setReferenceManifestsSingleton` before requiring the module.
Closes NEXT-2579
Previously, runtime errors would not be recovered from. Like the webpack
implementation, this addresses the issue by performing a full page
reload when recovering from a runtime error.
Test Plan: `test/development/acceptance-app/error-recovery.test.ts --
Error recovery app default stuck error`
Closes PACK-2569
This test case was added in #59752, but this doesn't seem like the
correct behavior.
The original PR was intended to be smart about resolving `/default.tsx`
to a route group default (e.g. `/(foo)/default.tsx`) when one wasn't
specified. But since the route group is creating a new hierarchy in the
tree and defines its own layout, if the route group layout doesn't
specify a default, then the not found behavior seems correct.
To fix unexpected not-found behavior in this case, you should specify a
default at the same level as the layout where the missing slot(s) might
be rendered.
Closes NEXT-2565
This onClick isn't actually being used by the test and seems to be
causing a flake unrelated to the test assertions. This removes the
unused code for now so we can still keep the relevant part of the test
in-tact. (Specifically, this test is asserting that we're using the
correct prefetch cache entry for interception routes that originate from
different trees but resolve to the same URL)

### What
When a prefetch cache entry becomes "stale", it'll remain stale until
eventually it gets evicted. However during that stale window, the cache
is never revalidated, and so instant navigations stop working and data
is fetched from origin every navigation.
### Why
The `lastUsedTime` entry on the prefetch cache is currently only updated
after the first read. Once it becomes stale, `applyFlightData`'s
recursive functions will see that there is no longer a reusable prefetch
cache entry, and will trigger a lazy fetch of the new data on every
subsequent navigation.
### How
This updates prefetch cache handling to always ensure we’re using a
fresh or reusable prefetch cache entry. This means that stale prefetch
entries will be refreshed on a navigation event. As a result of this,
I’ve had to disable one of our tests that relies on this stale cache
behavior. It’s not ideal that we’re blocked on the loading boundary when
fetching child segment data—ideally we can refactor this to cache the
loading component in the CacheNode and copy it over on navigations,
similar to how ‘head’ is handled. I’ll work on this in a separate PR.
Note: The new client cache test for this is disabled in PPR for the same
reason as the other tests: auto prefetching with PPR navigations is
currently loading fresh data rather than reusing the prefetch cache.
Fixes#58969Fixes#58723
Closes NEXT-1904
### What & Why
This PR helps fixes a long time tree-shaking issue that if you're import
some identifiers from client components, the whole client component is
being included in the client chunk. Because we're using import eager
mode in webpack to include all the client component modules that make
sure they're present in SSR entry and browser entry when they're
transformed to client reference on RSC layer.
But the way we collect client components is a bit "aggressive" where
contains some spaces to optimize.
### How
We change the collected client components from simpliy collecting it
resolved module request, into collecting both the imported identifiers
(by server components) and the module request. And when we inserted the
used client components imports into the SSR and Client entry, leverage
webpack magic comments `"webpackExports"` to only contain the used
exports in the bundle. Thank you webpack for this nice feature : )
Along the way we also fixed an issue that when you only used default
export, the `default` export itself should also be proxied when the
bundle is in ESM.
#### Notice
There's a limitation yet that it can't work with barrel file, if you
have a shared component `index.js` to re-export the changes several
client components there and you only partially import few from
`index.js` it won't work. For the cases that the node_modules package
contain a barrel file importing multiple client components, please use
[optimizePackageImports](https://nextjs.org/docs/app/api-reference/next-config-js/optimizePackageImports)
config for now. We'll have follow up optimizations
### Testing Result
If we compare the `react-aria-components` the reproduction from #60246,
you'll see the result being optimized a lot:

When I tried to use --no-import-alias, I thought that it would
automatically use the default alias (@/*), but it does not.
### Why?
Each option has --no prefix control but import-alias has no --no prefix
control to give default value to program.
In an [Interactive](https://nextjs.org/#interactive) approach, the user
can select a prompt; `Would you like to customize the default import
alias (@/*)? No / Yes.` If the user selects no, then the default alias
is applied with @/*.
### How?
Implementing a condition solve the problem for general purpose. If
arguments includes `--no-import-alias` then the importAlias section
automatically apply the default value.

### What?
Fix one assertion about CSS files emitted by turbopack.
### Why?
Turbopack generates `/_next/static/chunks/2225ce._.css`, which does not
match the regex.
Note that it has `._.css`. The previous assertions match on
`[^.]+\.css`, which does not support two dots in the file name.
I tried `/<link rel="stylesheet" href=".+\.css(\?v=\d+)?"/g`, but it
captured 3 `link` tags at once. So I used `/<link rel="stylesheet"
href="[^<]+\.css(\?v=\d+)?"/g`.
### How?
Closes PACK-2413
### What?
`css-loader` seems to have a linting rule for invalid CSS Modules.
[My Turbopack PR](https://github.com/vercel/turbo/pull/7381) implements
the same rule for `swc_css` and `lightningcss`, and this PR is for
enabling related test suite and updating the jest snapshot.
### Why?
`css-loader` has a similar linting rule.

### What?
Fix one assertion about CSS files emitted by turbopack.
### Why?
Webpack generates 3 links with `?v=` query, and 2 extra links without
`?v=` query. Turbopack does not have query string, so we match 5 links.
### How?

### What
* Narrow down the metadata base warnings only when there's any relative
urls need to be resolved, if there's only absolute urls present, no need
to resolve and we don't warn.
* Polish the error message, updated from "metadata.metadataBase is not
set ..." to "metadataBase property in metadata export is not set ..."
### Why
It will be confusing if we're still show metadataBase warning when
there's no need to set one, since the social image cards only have
absolute urls
Closes NEXT-2426
### What
We should respect the `trailingSlash` config for metadata canonical url,
this PR is adding the handling for strip or keep the trailing slash for
canonical url. Passing down trailingSlash config to metadata resolving
to decide how we handle it.
### Why
The tricky one was `/` pathname, when visiting the origin directly, that
it will always have at least `/` in the URL instance. But for the
default `origin`, it shouldn't show the `/` if the `trailingSlash`
config is `false`. Also it should show trailing slash for all pathnames
if that config is enabled.
BTW there's a `__NEXT_TRAILING_SLASH` env but since we're using the
fixed nextjs runtime module, so this can't be dynamically replaced in
the metadata resolving modules. So we didn't use it
Fixes#54070
Closes NEXT-2424
### What
Following an anchor link to a hash param, and then attempting to use
`history.pushState` or `history.replaceState`, would result in an MPA
navigation to the targeted URL.
### Why
In #61822, a guard was added to prevent calling `ACTION_RESTORE` with a
missing tree, to match other call-sites where we do the same. This was
to prevent the app from crashing in the case where app router internals
weren't available in the history state. The original assumption was that
this is a rare / unlikely edge case. However the above scenario is a
very probable case where this can happen, and triggering an MPA
navigation isn't ideal.
### How
This updates `ACTION_RESTORE` to be resilient to an undefined router
state tree. When this happens, we'll still trigger the restore action to
sync params, but use the existing flight router state.
Closes NEXT-2502
We switched to `pnpm` for testing instead of `yarn` for e2e tests
containing customized node_modules packages, it works with
`node_modules` folder before. Rename the existing `node_modules_bak`
hack to make it easy to test with.
Previously we use `yarn` but it will clean `node_modules` folder so we
have to use another script to copy packages, it's not a required thing
now so we can test package from node_modules directly without renaming
folders locally
Closes NEXT-2496
This ensures we don't normalize the `distDir` in the webpack config in

### What
Disable swc transform optimizer for node_modules in browser layer of app
router bundles
Fixes#61858Fixes#60644Fixes#60920Fixes#61740
Closes NEXT-2418
### Why
In browser there could be not only one runtime, it could have both js
worker and browser. In js worker the `typeof window` is not as same as
in browser, so disabling the swc optimizer which will replace the code.
Leave the condition as it as.
### Why?
I really dislike the way `.chain` works right now, it shouldn't mutate
the `BrowserInterface`, this PR changes it so it's just a pure chain
without weird side effects.
One example with the current version (before this PR):
```
const el = browser.elementByCss('#version-2')
await el.text()
// throws
await el.text()
```
### Additional Changes
- removes selenium (which is completely unused)
- updates playwright
- makes the playwright tracing not error all the time
### What
When a global not found page is rendered, and when the not-found page or
containing layout has a link with `prefetch: auto` back to the root
page, the router would update the URL but not correctly swap out the
not-found component with the page component.
### Why
With auto prefetching (which is the default when `prefetch` is left
unspecified on a link), the router will perform a partial prefetch on
dynamic pages. This means it'll fetch the flight data _without_ React
nodes and store it in the prefetch cache. On navigation, this is used to
determine where we already have cached React nodes and where we need to
trigger a lazy fetch to get new data. However, global not found pages
are peculiar in that they will always contain a data path like: `['', {
children: ['__PAGE__', {}] }]` since they are inserted at the root. This
means that if there's also a page component that corresponds with the
same path, the router will incorrectly think it already has cache node
data for it.
### How
During SSR when the `asNotFound` flag signals to the renderer that the
component we're rendering is matching the global not-found page, we
modify the segment key to be something unique so the data path won't
collide with a top-level page.
In
[fc01c8e](fc01c8e7f7)
I added handling only on the server to modify the segment key. This
still fixes the issue, but at the cost of triggering an MPA navigation
on the client because it's treated as a root layout change
In
[69d5687](69d5687765)
I added client handling to not treat this special segment key as a root
layout change, and to signal to the router it needs to refetch the data.
This ensures we don't do an MPA navigation.

In `v14.0.2-canary.1` users started noticing more memory errors
especially with many edge runtime configured pages. After investigation
it seems this can be related to the additional transpiling we configured
in https://github.com/vercel/next.js/pull/59569 and
https://github.com/vercel/next.js/pull/57784
To help alleviate this we are updating the default swc loader to have an
additional check to see if no special features such as `next/font`,
`next/dynamic`, or `use server/client` directives are present and then
no-oping in the loader to avoid additional overhead for a majority of
modules.
For monitoring regressions our `stats-app` has been updated with
repeated edge-ssr routes to hopefully help us keep an eye on memory or
cache size issues.

Closes NEXT-2479
### What
When navigating back to a page that you had already loaded, it currently
results in a prefetch cache miss and will re-trigger any data
fetching/loading despite it being available.
### Why
When creating the initial router state, the prefetch cache is
initialized to an empty map.
### How
This uses the `initialTree` passed from the server to seed the cache for
that route with flight data.
Closes NEXT-2001
### What
Prefetches to pages within a shared layout would frequently cache miss
despite having the data available. This causes the "instant navigation"
behavior (with the 30s/5min TTL) to not be effective on these pages.
### Why
In #59861, `nextUrl` was added as a prefetch cache key prefix to ensure
multiple interception routes that correspond to the same URL wouldn't
clash in the prefetch cache. However this causes a problem in the case
where you're navigating between sub-pages. To illustrate the issue,
consider the case where you load `/foo`. This will populate the prefetch
cache with an entry of `{foo: <PrefetchCacheNode}`. Navigating to
`/foo/bar`, with a link that prefetches back to `/foo`, will now result
in a new cache node: `{foo: <PrefetchCacheNode>, /foo/bar%/foo:
<PrefetchCacheNode>}` (where `Next-URL` is `/foo/bar`). Now we have a
cache entry for the full data, as well as a cache entry for a partial
prefetch up to the nearest loading boundary. Now when we navigate back
to `/foo`, the router will see that it's missing data, and need to
lazy-fetch the data triggering the loading boundary.
This was especially noticeable in the case where you have a route group
with it's own loading.js file because it creates a level of hierarchy in
the React tree, and suspending on the data fetch would result in the
group's loading boundary to be triggered. In the non-route group
scenario, there's still a bug here but it would stall on the data fetch
rather than triggering a boundary.
### How
In #61794 we conditionally send `Next-URL` as part of the `Vary` header
if we detect it could be intercepted. We use this information when
creating the prefetch entry to prefix it, in case it corresponds with an
intercepted route.
Closes NEXT-2193
### What
When navigating to a page that uses a loading boundary + parallel route,
an empty white screen would be displayed rather than the loading state /
final state
### Why
With parallel routes, the RSC data is an array of data paths, each
corresponding with one of the parallel segments rendered on the page.
During the navigation event, when we iterate over this data, we call
`applyFlightData` with this data path & an empty cache node.
`applyFlightData` checks to see if the flight data contains cache nodes
("seed data"). If it doesn't, then that means it has no work to do, and
it bails out. Pre-PPR and in the case of having a `loading.js` file,
`walkTreeWithFlightRouterState` doesn't return any seed data, just
router state. This means that `applyFlightData` will not have any work
to do on the new cache node, and leaves it untouched.
Once `applyFlightData` is finished, but while still in the flight data
path loop, we reassign `currentCache` to the empty cache object we
created prior to `applyFlightData`. But since that cache node has
remained empty, the next iteration of the loop is going to be inspecting
a now empty cache, rather than the actual "current" cache. Now there's
no existing cache to copy into the new cache. The app now doesn't know
about any cache nodes.
### How
It doesn't seem like we should be re-assigning `currentCache` to the new
cache. In the context of a navigation, it seems more accurate to always
assume `currentCache` is the cache _now_, since it won't actually be
applied to the state until the action has finished (`mutable.cache` is
currently taking care of this).
Closes NEXT-2223
Fixes#61080
followup to: https://github.com/vercel/next.js/pull/60645
### Background
When prerendering the determination of whether a prerender is fully
static or partially static should not be directly related to whether
there is a postponed state or not. When rendering RSC it is possible to
postpone because a dynamic API was used but then on the client (SSR) the
postpone is never encountered. This can happen when a server component
is passed to a client component and the client component conditionally
renders the server component.
Today if this happens the entire output would be considered static when
in fact the flight data encoded into the page and used for bootstrapping
the client router contains dynamic holes. Today this is blocked by an
error that incorrectly assumes that this case means the user caught the
postpone in the client layer but as shown above this may not be the
case.
### Implementation
A more capable model is to think of the outcome of a prerender as having
3 possible states
1. Dynamic HTML: The HTML produces by the prerender has dynamic holes.
we save the static prelude but expect to resume the render later to
complete the HTML. This means we will resume the RSC part of the render
as well
2. Dynamic Data: The HTML is completely static but the RSC data encoded
into the page is dynamic. We don't want to resume the render but we do
need to produce new inlined RSC data during a Request.
3. Static: The HTML is completely static and so is the RSC data encoded
into the page. We save the entire HTML output and there will be no
dynamic continuation when this route is visited.
Really 1 & 3 are the same as today (Partially static & Fully Static
respectively) but case 2 which today errors in a confusing way is now
supported.
In addition implementing the Dynamic Data case the old warning about
catching postpones is removed. The reason we don't want this is that
catching postpones is potentially a valid way to do optimistic UI. We
probably want a first-party API for it at some point (and maybe we'll
add the warning back in once we do) but imagine you do something dynamic
like look up a user but during prerender you want to render as if the
user is logged out. you could call `getUser()` in a try catch and render
fallback UI if it throws. In this case we'd detect a dynamic API was
used but we wouldn't have a corresponding postpone state which would put
us in the Dynamic Data case (2).
Another item to note is that we can produce a fully static result even
if there is a postponed state because users may call postpone themselves
even if they are not calling dynamic APIs like headers or cookies. When
this happens we don't want to statically capture a page with postponed
boundaries in it. Instead we immediately resume the render and abort it
with a postponed abort signal. This will cause the boundaries to
immediately enter client render mode which should speed up recovery on
the client.
#### Technical Note
Another note about the implementation is that you'll see that regardless
of which case we are in, if there is a postponed state but we consider
the page to be Dynamic Data meaning we want to serialize all the HTML
and NOT do a resume in the dynamic continuation then we immediately
resume the render with and already aborted AbortSignal. The purpose here
is to mark any boundaries which have dynamic holes as being
client-rendered.
As a general rule if the render produces a postponed state we must do
one of the following
1. save the postponed state and ensure there is a dynamic continuation
that calls resume
2. immediately resume the render and save the concatenated output and
ensure the dynamic continuation does NOT call resume.
or said another way, every postponed state must be resumed (even if it
didn't come from Next's dynamic APIs)
#### Perf considerations
This PR modifies a few key areas to improve perf.
Reduces quantity of *Stream instances where possible as these add
significant overhead
Reduces extra closures to lower allocations and keep functions in
monomorphic form where possible
Closes NEXT-2164
Previously, this error was confusing because it made it sound like the
`sizes` prop was missing. This was because the default value of `sizes`
is `100vw` so the previous code couldn't tell the different between
implicit vs explicit `100vw`.
This PR changes the code to read the input value from the `sizes` prop
and prints a better warning.
Fixes NEXT-2441
There was a bug where if the root hydrates and then an update happens
the intitial server data response can be replaced by one that is
completely empty and will never resolve. This can lead to a frozen
hydration that blocks interactivity. This udpate makes it so it is
impossible for the initial data response to ever be created more than
once.
Making a regression test is tricky because this relies on subtle timing
of hydration, updates, and when the inline chunks arrive in the stream.
The original implementation is just not safe in that it violates the
rules of react and the new one is self-evidently unable to produce a
similar situation so as long as our existing test suite passes that must
be sufficient absent a good alternative to making a specific regression
test
Closes NEXT-2420
In #61794, the routes manifest is used to find the interception route rewrites in `next-server` and computed on the fly in `next-dev-server` based on `appPaths`.
The edge runtime doesn't have access to the routes manifest nor a full list of app paths. This writes an entry for the edge runtime to make the interception routes readable, and adds plumbing to return them in the `getInterceptionRouteRewrites` handling in `web-server`. This is what we use to signal to the server whether to return ‘Next-URL’ in the Vary for RSC requests.
This piggybacks on the existing interception routes test but adds an edge runtime case.
Closes NEXT-2304
To ensure that we properly cache data for routes that change based on `Next-URL` (which is used for route interception), this adjusts how we set the `Vary` header to conditionally include `Next-URL`.
The `Next-URL` request header only impacts the response for routes that are intercepted. When we detect that path we're handling could be intercepted, we add `Next-URL` to the vary. This signals in #61235 to prefix these cache entries with `nextUrl` if the response might vary based on it.
Closes NEXT-2398
### Fixing a bug
### What?
Fix remotePatterns when all paths and/or domains are allowed.
### Why?
micromatch creates a very strange regex for all paths -
`/^(?:(?!\.)(?:(?:(?!(?:^|[\\/])\.).)*?)[\\/]?)$/`. That is, paths
cannot start with a dot or contain a slash followed by a dot.
Interestingly, here are some valid paths:
- /a/a.a/6a00d8341c4fbe53ef02c8d3a82122200d-600wi
- ////a/a.a/6a00d8341c4fbe53ef02c8d3a82122200d-600wi
- ///:?%;№%/a/a.a/6a00d8341c4fbe53ef02c8d3a82122200d-600wi.\/
- /:./6a00d8341c4fbe53ef02c8d3a82122200d-600wi.\/
And here are some invalid ones:
- /.a/6a00d8341c4fbe53ef02c8d3a82122200d-600wi
- /a/.a/6a00d8341c4fbe53ef02c8d3a82122200d-600wi
- ./a/6a00d8341c4fbe53ef02c8d3a82122200d-600wi
I don't think this check makes any sense.

If the user allows all (`**`) - it means any path or domain will be
considered valid.

This implements falling back to try multiple locations loading chunks
for sourcemap tracing.
Unfortunately, when RSC replays server errors on the client, it does not
carry over the [0] symbol used to annotate server frames. Instead,
errors are recreated by React and only include the message and stack.
This allows more tests to pass, as we are able to correctly trace stack
frames by loading the appropriate server chunk.
Closes PACK-2442
### What
This PR injects a build-time error for the turbopack if
`client|server-only` is imported in incorrect context. The basic idea is
using resolve plugin, so in resolve time if matching context (which
alises erroneous import), raise a build time error.
Unfortunately this won't fix all of the tests in `invalid-imports`, due
to
1. resolveplugin does not have way to trace import from transformed, so
not able to detect `styled-jsx` from using `<styled..` tags
2. webpack (in our implementation) and turbopack's resolveplugin have
different order of transform / module trace chain, so enabling resolve
plugin in some context raises build error instead of runtime error in
rsc-build-error.

### What
Exclude precompiled react packages from browser layer loaders coverage.
### Why
Since we're transpiling all the browser layer code now after #59569,
then SWC will also compile react. But when it compiles
`react.production.min.js` it gives me with the code and ESM helper
inserted
```js
import { _ as _type_of } from "@swc/helpers/_/_type_of"; // This is not correct
var l = Symbol.for("react.element"), n = Symbol.for("react.portal"), p = Symbol.for("react.fragment"), q = Sym
bol.for("react.strict_mode"), r = Symbol.for("react.profiler"), t = Symbol.for("react.provider"), u = Symbol.f
```
This makes bundler think it's a ESM package but actually it's CJS, which
converts the module into `{ default: .., __esModule }` instead of the
original react module.
When you're using `React.useEffect` or other API through namespace
import (`import * as React from 'react'`), this will break the module
exports check in bundling as the property doesn't directly attached to
the module now. This PR disabled the transform for precompiled react
packages now and will see the deeper issue in next-swc side later.

### Why?

_after_ we did some parsing on the config object, which is different
from what the user is expected to pass.

API's that cause the render to be marked as dynamic (like
`unstable_noStore()`) and also a navigation API, these errors may race
to the end. In the case where the navigation error does not beat out the
error emitted by dynamic API's will still trigger the detection warning
that's present to warn you about situations where you may have
accidentally caught the error.
### How
This resolves this issue by explicitly checking for navigation signals
(errors) thrown during the render, and not displaying the "caught
dynamic API" error and console warning.
Closes NEXT-2037
## History
Previously, we added support for `squoosh` because it was a wasm
implementation that "just worked" on all platforms when running `next
dev` for the first time. However, it was slow so we always recommended
manually installing `sharp` for production use cases running `next
build` and `next start`.
Now that [`sharp` supports
webassembly](https://sharp.pixelplumbing.com/install#webassembly), we no
longer need to maintain `squoosh`, so it can be removed. We also don't
need to make the user install sharp manually because it can be installed
under `optionalDependencies`. I left it optional in case there was some
platform that still needed to manually install the wasm variant with
`npm install --cpu=wasm32 sharp` such as codesandbox/stackblitz (I don't
believe sharp has any fallback built in yet).
Since we can guarantee `sharp`, we can also remove `get-orientation` dep
and upgrade `image-size` dep.
I also moved an [existing `sharp`
test](https://github.com/vercel/next.js/pull/56674) into its own fixture
since it was unrelated to image optimization.

### What?
This PR wraps up supporting rsc transforms (mostly for the assertion) in
Turbopack. PR contains a few changes to support it, including:
- adjust / expand transform rules for the corresponding contexts
- fix file name / node_modules check
- extract visitors for the assertion / transforms
This change enables most of the rsc-build* tests and some more other
tests. The only failing tests in the rsc-build-errors is due to
Turbopack not triggering hmr with empty file.
Closes PACK-2303
### What & Why
We have a modularize imports config for `next/server` before, which will
transform the `next/server` imports to directly import from the actual
file, for instance: `import { NextRequest } from 'next/server'` will
become `import { NextRequest } from
'next/dist/server/web/exports/next-request'`, where the NextRequest is
exported as default export. This is fine in most case until you're using
a ESM pkg, then it will be resolved as `{ default: NextRequest }`
according to the spec. Since it's a ESM import to a CJS module in
`next/dist`.
Since we already have the ESM alias introduced in #59852 , this can
handle the case more properly.
### How
Remove the modularize imports config for `next/server`, use the ESM api
alias instead.
Migrate the cjs optimizer tests from middleware to a separate endpoint
`/cjs/server`. As now ESM imports for next/server are not going to get
tree-shaken in dev, but since we don't have image response there it's
still fine.
Closes NEXT-2376
Closes NEXT-2374
### What
When navigating to a page with dynamic params using a certain casing,
and then following a link to another page using _different_ casing for
the same param, the router would get stuck in an infinite suspense
cycle.
### Why
On the client we normalize cache keys by lowercasing the values for
dynamic segments. However the RSC data for each segment wouldn't have
this same casing logic applied. This is causing the router to not
recognize that there is already RSC data available for that segment,
resulting in an infinite suspense cycle.
### How
The `toLowerCase()` logic shouldn't be needed here. Technically we could
leave this in place and update `matchSegment` to also apply the
lowercase logic, but currently there are too many utility functions that
parse segments to comfortably make that change. I confirmed that the bug
related to why we lowercased these router cache keys is no longer
present after making this change.
Fixes#61722
Closes NEXT-2377
### What
Client-side transitioning to a page that triggered a loading boundary
with async metadata would cause the transition to stall, potentially
getting stuck in a refetch loop.
### Why
In layout-router, we trigger a "lazy fetch" when we encounter a segment
that we don't have cache nodes for. This calls out to the server and
suspends until the data fetch is resolved, and applied to the router
tree. However after suspending but before updating the client router, we
set `childNode.lazyData` to null. When we unsuspend from the server
patch action, `childNode.rsc` might still be missing and clearing
`lazyData` means we've blown away the reference to the fetch we already
had pending, triggering a refetch loop.
### How
This removes the logic that mutates the cache node in render, as this is
not concurrent safe, and doesn't appear to be needed for anything.
Fixes#61117

### What
#### Core
This PR respect the error's digest when recieves new error occurred from
server side, and it will be logged into client on production with the
same `digest` property.
If we discover the original RSC error in SSR error handler, retrieve the
original error
#### Tests
* Move the errors related tests from `test/e2e/app-dir/app` to a
separate test suite `test/e2e/app-dir/errors`
* Add a new test case for logging the original RSC error
* Add a new test case for logging the original Server Action error
### Why
This will help associate the `digest` property of the errors logged from
client with the actual generated server errors. Previously they're
different as we might re-compute the digest proper in handler that react
server renderer thinks it's a new error, which causes we have 2
different errors logged on server side, and 1 logged on client side. The
one on client side can associate to the server errors but it's from
react renderer which is not the original error.

### What?
I forgot to check the `preload` option when implementing it and just
looked at the `subsets`.
This also fixes duplicate preload tags by adding them to a set in the
default `_document.tsx`

This PR fixes `.eslintrc.json` not being created after the user runs
`next lint` and selects an option of `Strict` or `Base`.
The reason is that the lint check was looking for `pages` and
`src/pages` only. Added `app` and `src/app` to be checked also.

### What?
Fixes `setAssetPrefix` when running on a custom server using next()
function
### Why?
Looks like when we run next custom server, there are 2 instances created
to handle this case
* main server in `/server/next.ts`
* and Render server `./server/lib/render-server.ts`
The issue mainly happens when calling `setAssetPrefix` it will update
only the main server and not render server
``` javascript
const next = require('next')
const app = next({ });
app.setAssetPrefix('my-fancy-cdn/static');
app.render(); // render server is used instead of the main server
```
### How?
when calling `setAssetPrefix` on the main server also update the render
server with the same information.

### What?
Expose the `MiddlewareConfig` interface.
### Why?
You can now `import type { MiddlewareConfig } from "next/server"` to
type the `config` object in your `middleware.ts` file.
Now you an type the entire file for example like so:
```ts
// middleware.ts
import type { NextMiddleware, MiddlewareConfig } from "next/server"
export const middleware: NextMiddleware = async (req) => {
//...
}
export const config: MiddlewareConfig = {
//...
}
```
### How?
Re-exported the interface from its current location via
`server/web/types`, to colocate it with `NextMidldeware`.
I wonder if we could somehow type this file automatically, but it might
be dependent on https://github.com/microsoft/TypeScript/issues/38511

### What
When attaching a rejection listener to a server action promise, in the case of network errors, the rejection handler would be skipped and it'd throw an error that crashes the application.
### Why
When we refactored these reducers to no longer suspend, it caused the rejection handling logic we have to no longer make sense. In this case we're working with a native promise that won't have a `status` property, so we'd re-throw the error and not call `reject`.
### How
This removes the special status handling logic and makes the rejection handler always call `reject` with the error. This will either be handled by user code or let the error bubble to an error boundary.
I also cleaned up some mutable code that is no longer needed now that these reducers aren't replayed.

Fixes#58638
## What?
Fixes the `should update server components pages when env files is
changed (edge)` tests. In order for changes to the environment to apply
to edge-runtime routes we need to call `clearModuleContext`, currently
that only supports a single path being provided, but in Turobpack the
compilation is much more granular than webpack, in case of webpack we
loop through all items coming out of the compilation and invalidate them
regardless, which is not needed for Turbopack. Instead, when an
entrypoint (route) is recompiled it'll automatically only invalidate
that part. For `.env` changes that don't affect compilation, which is
what the test checks, this wouldn't be sufficient as there is no
compilation difference between changing those env vars. In the case that
you change `.env` / tsconfig/jsconfig we have to clear all module
contexts, which is what this PR implements.

## What?
Whenever `.env` related files or tsconfig/jsconfig changes there's a
call to `invalidate()`, as far as I found the only call to
`invalidate()` even, which wasn't implemented for Turbopack yet. For
`NEXT_PUBLIC_` changes normal Turbopack HMR will kick in already but
this test was checking env vars that do not affect the compiled output,
so Turbopack would not trigger a HMR as no inputs changed. Similarly
webpack doesn't either and it implements this call in a similar way.
For edge runtime there's a different bug where changes are not
propagated even when you refresh, so while this change does fix another
bug for edge runtime it doesn't solve that underlying issue where the
values don't update to begin with. I'll investigate that next.

### What?
This adds a method to optionally detect disk, network, and env access
access during a build and write this to a file.
### Why?
This will be consumed by Turborepo to determine **if** a build can be
cached, and if so, **how** it should be cached.
### How?
This implements a proxy that can be selectively applied to functions to
watch their access to disk, network, and env. For Turborepo, we only
care about what can alter the build output, to achieve this, we trace
the config load, and the static page generation.

### What
When using a default slot that re-exports another page, the CSS entries
(and presumably other client reference modules, like JS entries) that
correspond with the re-exported page won't be loaded, resulting in CSS
styles not being applied.
### Why
`next-app-loader` constructs the path to the default segment but special
cases the `children` slot (which is used as the page), to mark the
segment as an empty string. This is so that the parallel default file
can be loaded. However the way that `defaultPath` is constructed, it
assumes that `actualSegment` won't be an empty string, and constructs an
invalid path like so:
`app/example//default.tsx`
When we go to look up the JS/CSS entries from the client reference
manifest, the key will be incorrect and so it won't find the files for
it, resulting in this bug.
### How
This moves the `/` delimiting to be part of the creation of the
`actualSegment` variable so that we only append it when we know we
aren't setting it to be an empty string.
Fixes#52245Fixes#49871
Closes NEXT-2309
Closes NEXT-2310
When using `next/dynamic` in server components to load a client
component with named export, we shouldn't dot into the prop name since
client component reference as it's already a valid react component type.
It would work with `default` prop but not other named exports.
Let's say `mod` is a dynamic imported module
```
mod.Button.default
```
will become the client reference key
```
mod#Button#default
```
Which means in module `mod`, get `Button` export, then `default`
property of it, which is wrong but it's a valid key in the client
reference roxy.
This PR checks if they're client module, then return itself as dynamic
imported component type for `next/dynamic` if it is one.
Fixes#61046
Closes NEXT-2229
### What
Catch-all parallel slots were being incorrectly matched to the root of their segment. For example, `@foo/[...catchAll]/page` as a parallel route on `/page.tsx` should not match on `/`, but it should match on `/foo`, `/bar`, ...etc
### Why
The catch-all route normalization logic doesn't treat optional catch-all routes differently from catch-all routes. The assumption was if any catch-all route was found, that it should match the path that shared its prefix.
### How
This updates the normalization logic to handle optional-catchall as it was in the original implementation. For regular catch-all, we ensure that the catch-all base path (for `/[...slug]` that'd be `/`) isn't identical to the path we'd match it to.

uses these. This is hard to trace down where exactly the error is from

Cloese NEXT-2265
When we apply `createActionProxy` twice to the same value, it currently
errors because we can't override the ID of it.
This PR makes sure that 1) when the value already have an ID defined, we
skip setting it again; 2) all the action IDs are being tracked even for
duplicated ones.
Note that it's technically impossible to "detect" the duplication here
(via static analyzation) and only set it once. For example:
```ts
'use server'
export async function foo () {}
export const bar = a_value_we_dont_know_yet ? foo : async () => {}
```
So, the compiler will always wrap `createActionProxy` for every exported
value and assume they're different Server Actions (hence different IDs).
With this fix, if we find that it's already defined before, we just
return the defined reference as they're strictly identical so the ID
does't matter.
Closes#54655, closes#61183.
Closes NEXT-2264
This PR fixes the cookie merging logic in Server Actions. Specifically,
when users do `cookies().set(...)` or `cookies.delete(...)` with a
`redirect()` to an internal route followed. Currently, we are just
concatenating the original cookies (request cookies) and the mutated
cookies. That introduces several issues, like it can't override or
delete an existing cookie.

## What?
Currently we have a test that checks for:
```
{
"name": "my-package",
"edge-light": "./edge-light-file.js"
}
```
However we should only support it in `exports` and `imports` conditions,
which is also what packages published use currently. This updates the
tests to reflect the correct behavior in Turbopack.

### What?
### Why?
### How?
Closes NEXT-
Fixes #
-->
Closes NEXT-2262
## What?
Fixes the condition being checked to match for Turbopack which always
adds the blur.
Webpack needed to lazy eval blur during `next dev` but Turbopack can
always blur since its much faster.
Closes NEXT-2259
### What?
When using layouts in multiple parallel route slots, only 1 of the
layouts would render.
### Why?
The `resolveParallelSegments` logic responsible for populating the
loader tree was incorrectly bailing if it found another parallel route
that matched a page component.
### How?
I did my best to update this loader code with some more comments to make
it a bit easier to reason about, and also made some slight refactors.
But the gist of the fix is just ensuring that each parallel route (that
isn't a direct match on the `children` slot) is resolved as an array, so
that when the subtree is created, it doesn't skip over the slot.
Fixes#58506Fixes#59463
Closes NEXT-2222
## What?
Turbopack has the correct behavior of preferring `.ts` / `.tsx` for
first-party code. In Webpack we don't have a way to only resolve
`.ts`/`.tsx` in first-party code. Turbopack doesn't resolve `.ts`/`.tsx`
in `node_modules`.

When there's `useSearchParams` hook triggers the bailout to client side
rendering, users might hard to find where it's from since it could
either from users code base or third party libraries. Adding the stack
trace for it so they could at least investigate which line is throwing
from the server bundle. Will improve it in the later future when we can
give more insights.

Closes NEXT-2239
### What & Why
Using parallel routes with edge runtime would cause a build error when
using a default segment, because edge runtime has special handling to
[read the client reference
manifests](12c9040568/packages/next/src/build/utils.ts (L1543-L1555))
for these when determining if a page is static.
### How
In a similar fashion to how we exclude static checks on reserved pages,
I added similar handling for app pages.
Fixes#60917
Closes NEXT-2241
## What?
`exportPathMap` didn't work when Turbopack was enabled because the
`serializeNextConfig` function mutates the original values, overriding
`exportPathMap`.
This PR changes the serialization to copy the object and mutate only the
copied object.
Also refactored the test that was checking `_next`, the better way to
test that is to have the page render something dynamically, which is
what is added in this PR.

Closes NEXT-2225
### What?
This fixes 2 issues with app 404 pages.
1. The root layout in a group was previously ignored when hitting the
404 page.
2. The default app 404 page was missing the correct path for dev
`/not-found` so it would fall back to the pages 404 page.
Closes PACK-2241
Fixes#60688
### What
When users're using nextjs server API that break the build, and error
with incorrect client components usage.
Instrument should be treated as server components or server-only build
target, instead of being treated as client components.
### How
We added a new layer `instrument` for instrument hook bundling, and
apply it with the rsc server webpack loaders
Fixes#57563
Closes NEXT-2181
Closes NEXT-1994
### What?
Interception routes on dynamic paths don't currently work when PPR is
turned on, and instead trigger an MPA navigation to the full route.
### Why?
Route interception relies on the `Next-Flight-Router-State` header to
extract the dynamic params necessary to convert something like
`[locale]`, which would correspond with a URL of `/en`, to something
like `["locale", "en", "d"]`. (See [this
function](fbfd7b5f81/packages/next/src/server/app-render/app-render.tsx (L129-L137))
for more info). When PPR is turned on, we currently ignore this request
header and don't provide it to the functions that render the component
tree.
Without the flight router state, this function bails out and instead
will leave the segment key as `[locale]`. When the client router goes to
diff the current tree on the client with the response from the server,
it will detect a mismatch between the current segment and the incoming
segment, and trigger an MPA navigation in [this
block](fbfd7b5f81/packages/next/src/client/components/router-reducer/reducers/navigate-reducer.ts (L414-L416)).
### How?
This special-cases interception routes to not strip this header.
Closes NEXT-2215
### What
Fixes the string id that broken when sitemap is optimized to static
route.
### Why
When sitemap is optimized to static route in production, the route
argument is changed from `[[...__metadata_id__]]` to
`[__metadata_id__]`, so the type of it is also changed from array to
string that should reflect in the loader code.
Fixes#60894
Closes NEXT-2154
## What?
Fixes `should have <head> containing <meta name=\"viewport\"> followed
by <link rel=\"preload\"> for priority image` and `should add a blur
placeholder a statically imported x` (where x is a file format) in
Turbopack.

formalizes the concept of dynamic APIs inside Next to allow for varying
semantics beyond just staticGenerationBailout.
### Dynamic APIs
#### `markCurrentScopeAsDynamic`
useful to bail out of default caching semantics but does not imply a
Request specific data source was read. critically, this semantic is
ignored if you are inside a cache scope
#### `trackDynamicDataAccessed`
Must be called before reading any data source that is derived from
Request specific data. Currently this is `cookies()`, `headers()`, and
`searchParams`. This kind of data access inside a cache scope is
forbidden (it always should have been, but now it will error).
#### `trackDynamicFetch`
This one is unideal but the complexity of patch-fetch's current
implementation necessitates it for now. Essentially it will postpone if
we are prerendering. Long term this should be eliminated with a refactor
of patch fetch.
### Other Improvements
Also removes the `staticGenerationBailout` implementation as it has been
replaced with more specific logic in the places it was previously being
used.
One area that has also been enhanced is the proxy for app-route modules.
Previously we proxied the Request every time however when we are doing
non-static generation executions we generally don't want the overhead of
wrapping the request. In the refactor here I also improved the runtime
performance by using static proxy handlers and I believe I also fixed a
few bugs related to `clone` and `url`
In general there has been a bit of refactoring to clarify how we should
handle various render/execution states and a reduction in implicit side
effects for proper execution.
Another callout to notice is that app-route modules do not attempt a
static generation if they are force-dynamic regardless of the PPR
setting. Previously the PPR setting would opt them into this code path
which is not necessary because PPR itself does not work for routes, only
pages.

Fixes#59968
### TODOs
- [x] recreate [repro](https://github.com/williamli/nextjs-NEXT-2173)
- [x] patch `useSelectedLayoutSegment` to support parallel routes (see
"What")
- [x] check `useSelectedLayoutSegments` to see if it is affected
- [x] add test cases
- [x] finalise PR description
### What?
`useSelectedLayoutSegment` does not return the name of the active state
of parallel route slots.
#### Expected Behaviour
According to
https://nextjs.org/docs/app/building-your-application/routing/parallel-routes#useselectedlayoutsegments
> When a user navigates to app/@auth/login (or /login in the URL bar),
loginSegments will be equal to the string "login".
👉🏽 We should update the docs to explain `null` and __DEFAULT__ result as
well.
According to the [API reference for
useSelectedLayoutSegment](https://nextjs.org/docs/app/api-reference/functions/use-selected-layout-segment#returns):
> useSelectedLayoutSegment returns a string of the active segment or
null if one doesn't exist.
> For example, given the Layouts and URLs below, the returned segment
would be:
> <img width="881" alt="CleanShot 2024-01-20 at 14 50 52@2x"
src="https://github.com/vercel/next.js/assets/179761/bfaa34c8-3139-4ec3-bd70-4346c682e36b">
#### Current Behaviour
Currently a string "children" is returned for everything inside a
parallel route with active state and `__DEFAULT__` is returned if there
is no active state for the parallel route (since the `default.tsx` is
loaded). ~`null` is returned when the `default.tsx` is not loaded
(possibly caused by another bug, see test case 5).~
#### Reproduction
[GitHub Repo](https://github.com/williamli/nextjs-NEXT-2173) is created
based on the example provided in [Next.js docs for using
`useSelectedLayoutSegment` with Parallel
Routes](https://nextjs.org/docs/app/building-your-application/routing/parallel-routes#useselectedlayoutsegments).
#### Test Cases
1. If you visit https://next-2173.vercel.app/, you get loginSegments:
__DEFAULT__ (hard navigation) or children (soft navigation after
returning from a visit to /login)
2. If you soft nav to (/app/@auth/login and /app/@nav/login)
https://next-2173.vercel.app/login, you get
1. loginSegment: `children` (expected value should be `login`)
2. navSegment: `children` (expected value should be `login`)
3. If you soft nav to (/app/@auth/reset)
https://next-2173.vercel.app/reset, you get
1. loginSegments: `children` (expected value should be `reset`)
2. navSegment: `children` (expected value should be `login`)
4. If you soft nav to (/app/@auth/reset/withEmail)
https://next-2173.vercel.app/reset/withEmail, you get
1. loginSegments: `children` (expected value should be `withEmail`)
2. navSegment: `children` (expected value should be `login`)
5. ~If you hard nav to (/app/@auth/reset/withEmail)
https://next-2173.vercel.app/reset/withEmail, you get an unexpected
result due to possibly another bug:~
* ~navSegment is `null` on the deployed (Vercel) version, the navSlot is
*not* loaded~
* ~navSegment is `__DEFAULT__` on local dev, the navSlot loads
`/app/@nav/default.tsx`.~
### Why?
In `packages/next/src/client/components/navigation.ts`,
`getSelectedLayoutSegmentPath` is called and returns the correct
segmentPath for parallel routes (even though there is a TODO comment
indicating this function needs to be updated to handle parallel routes)
but `useSelectedLayoutSegment` failed to return the correct segment when
a parallelRouteKey is provided.
### How?
`useSelectedLayoutSegment` is updated to return
selectedLayoutSegments[0] for non parallel routes (original logic), but
it will return the last segments for parallel routes (or null if nothing
is active).
```
return parallelRouteKey === 'children'
? selectedLayoutSegments[0]
: selectedLayoutSegments[selectedLayoutSegments.length-1] ?? null
```

This PR adds a warning when attempting to optimize an animated image.
```jsx
<Image src="/image.gif" />
```
The warning looks like the following:
```
The requested resource "/image.gif" is an animated image so it will not be optimized. Consider adding the "unoptimized" property to the <Image>.
```
To remove the warning, add the `unoptimized` prop.
```jsx
<Image src="/image.gif" unoptimized />
```
We don't attempt to optimized animated images because it can be very
slow (30+ seconds) and sometimes deoptimizeds (the output is larger than
the input) so its best to serve the animated image as-is.
Closes NEXT-2199
Fix NEXT-2165
### What?
Addresses the limitation of #60240, where a dummy `default` file is
required in parallel route child slot to prevent errors in dev server
rendering (`TypeError: Cannot read properties of undefined (reading
'clientModules')`) as well as errors in build and deploy (`Error:
ENOENT: no such file or directory, lstat
‘/vercel/path0/.next/server/app/parallel-route/[section]/@part/[partSlug]/page_client-reference-manifest.js’`)
Without the `default.tsx`, builds and deployments will fail with:
<img width="956" alt="CleanShot 2024-01-18 at 02 12 36@2x"
src="https://github.com/vercel/next.js/assets/179761/80ba61bd-6ec0-4b16-a393-dc9375227e19">
local dev server will also crash with:

> TypeError: Cannot read properties of undefined (reading
'clientModules')
### Why?
Since `default.tsx` is not a compulsory when you have slot that are
specific and ends with a dynamic route segment, this PR extends support
so that it is possible mixing catch-all routes with specific
non-catchall routes without requiring an additional `default.tsx` .
This PR will allow the following test cases to pass:
```
it('should not add the catch-all route to segments that have a more specific [dynamicRoute]', () => {
const appPaths = {
'/': ['/page'],
'/[[...catchAll]]': ['/[[...catchAll]]/page'],
'/nested/[foo]/[bar]/default': [
'/nested/[foo]/[bar]/default',
'/nested/[foo]/[bar]/@slot0/default',
'/nested/[foo]/[bar]/@slot2/default',
],
'/nested/[foo]/[bar]': [
'/nested/[foo]/[bar]/@slot0/page',
'/nested/[foo]/[bar]/@slot1/page',
],
'/nested/[foo]/[bar]/[baz]': [
'/nested/[foo]/[bar]/@slot0/[baz]/page',
'/nested/[foo]/[bar]/@slot1/[baz]/page',
],
'/[locale]/nested/[foo]/[bar]/[baz]/[qux]': [
'/[locale]/nested/[foo]/[bar]/@slot1/[baz]/[qux]/page',
],
}
const initialAppPaths = JSON.parse(JSON.stringify(appPaths))
normalizeCatchAllRoutes(appPaths)
expect(appPaths).toMatchObject(initialAppPaths)
})
...
```
```it('should not add the catch-all route to segments that have a more specific [dynamicRoute]', () => {
const appPaths = {
'/': ['/page'],
'/[[...catchAll]]': ['/[[...catchAll]]/page'],
'/nested/[foo]/[bar]/default': [
'/nested/[foo]/[bar]/default',
'/nested/[foo]/[bar]/@slot0/default',
'/nested/[foo]/[bar]/@slot2/default',
],
'/nested/[foo]/[bar]': [

],
'/[locale]/nested/[foo]/[bar]/[baz]/[qux]': [
'/[locale]/nested/[foo]/[bar]/@slot1/[baz]/[qux]/page',
],
}
...
```
and allow parallel routes defined in this [code
repro](https://github.com/williamli/nextjs-NEXT-2165) to build.
### How?
`packages/next/src/build/normalize-catchall-routes.ts` is extended to
check `appPath` to see if it is:
1. the route is not a catchall
2. `isMoreSpecific` than the closest `catchAllRoute`.
where `isMoreSpecific` is defined as:
```
function isMoreSpecific(pathname: string, catchAllRoute: string): boolean {
const pathnameDepth = pathname.split('/').length
const catchAllRouteDepth = catchAllRoute.split('/').length - 1
return pathnameDepth > catchAllRouteDepth
}
```

## What?
Implements https://github.com/vercel/turbo/pull/7081. Ensures image
imports in the edge runtime have the correct asset url. Previously it
would be `/assets/file.hash.png` but it should be
`/_next/static/media/file.hash.png`.
Updates the image tests to correctly compare the values in Turbopack and
the values in Webpack. Currently it only checks webpack values, causing

### What?
### Why?
### How?
Closes NEXT-
Fixes #
-->
Closes NEXT-2194
### What & Why?
Interception routes depend on contextual information that are provided
via request headers. Specifically it needs to know about the
`Next-Router-State-Tree` when generating the interception route RSC
data, which isn't available at build time. This doesn't currently cause
any usage issues, but it erroneously emits static files & RSC payloads
that the client router won't be able to use and will instead fallback to
a dynamic request.
I removed some special case in an existing test since this fix also
resolves a discrepancy in behavior when PPR is turned on
### How?
This excludes interception routes from `appStaticPaths` at builds which
currently determines which pages should be statically generated.
Closes NEXT-2190
### Description
This PR refactors existing `analysis/get-static-page-info`, moves over
most of parse / ast visiting logic into next-swc's rust codebase. By
having this, turbopack can reuse same logic to extract info for the
analysis. Also as a side effect, this removes JS side parse which is
known to be inefficient due to serialization / deserialization.
The entrypoint `getPageStaticInfo` is still in the existing
`get-page-static-info`, only for extracting / visiting logic is moved.
There are some JS specific context to postprocess extracted information
which would require additional effort to move into.
Closes PACK-2088
## What?
There were a bunch of Sharp related tests failing when running the test
suite with Turbopack. The reason for this was that we automatically
detect the root of the project based on the closest lockfile (i.e.
package-lock.json). In this particular test a new package-lock.json was
added and since this suite is not yet isolated it cases problems.
This PR adds `outputFileTracingRoot` to explicitly provide the root of
the project, which ensures the right files are resolved.
Closes NEXT-2180
In both dev server and production build we both use `getStartServerInfo`
to log the basic info but for prod build we should always respect to use
"build" phase
Fixes#57927
Closes NEXT-2179
This:
- Makes makes reporting hmr changes more accurate by emitting an
explicit start event and lowering the aggregation period for reporting
completed turbo tasks
- Parameterizes the aggregation period, allowing JS subscribers to
request different intervals, such as for the next-rs-api test
- Aligns path pattern with webpack by normalizing its layer names
- Fixes a bug in `drainAndGetNext` where the stream never could drain
past the first item
- Sends `client-hmr-latency` spans from Turbopack in both page and app
router pages
Closes PACK-2252

### 🧐 What's in there?
`config.analyticsId` is a rarely-used mechanism, initially intended to
Next.js users hosting their application themselves and willing to report
Core Web Vitals to Vercel Speed Insights.
This platform specific mechanism can be replaced with the built-in
[`useReportWebVitals`](https://nextjs.org/docs/app/api-reference/functions/use-report-web-vitals).
### 🧪 How to test?
1. make a new Next.js app
1. define env variable `VERCEL_ANALYTICS_ID` to a dummy value
1. start your application in dev mode:
```shell
⚠ config.analyticsId is deprecated and will be removed in next major
version. Read more:
https://nextjs.org/docs/messages/deprecated-analyticsid
▲ Next.js 14.0.5-canary.58
- Local: http://localhost:3000
✓ Ready in 917ms
```
1. build your application:
```shell
▲ Next.js 14.0.5-canary.58
Creating an optimized production build ...
✓ Compiled successfully
Linting and checking validity of types .

1. remove the env variable, add a `next.config.js` file with a dummy
`analyticsId` variable:
```js
module.exports = { analyticsId: "UA-12345678-9" };
```
1. start your application in dev mode: it'll issue the same warning.
1. build your application: it'll issue the same warning.

### What
Follow up for #59852 , now you can use `next/og` if your nextjs app is
marked as ESM with `"type": "module"` in package.json.
### How
It's a bug in external handling, we shouldn't ESM import error for local
requests. Previously you'll see the below error but the
og import shouldn't be errored as it's not external package
```
Module not found: ESM packages (/.../app/opengraph-image.js) need to be imported. Use 'import' to reference the package instead
https://nextjs.org/docs/messages/import-esm-externals
```
Closes NEXT-2147
### What?
Follow-up to #60579 and #60750. Checking `startsWith` is not enough
because it hides the rest of the stack. Changed the test to check the
snapshot for Turbopack and webpack.
Fixes a bug where the stack lines showed `http (NaN:NaN)` as the source
lines.
Added support for source lines that don't have a open in editor.

Closes NEXT-2128
This PR fixes the issue where an inline Server Action gets exported. As
this isn't the designed use case for inline Server Actions (they're
supposed to be defined and used inside another closure, such as
components), we are not handling the export cases currently:
```ts
export async function action() {
"use server"
...
}
<form action={action}/>
```
...which gets compiled into:
```ts
export async function action() {} // No-op function
<form action={...actionReference...}/>
```
Note that everything works inside this module until you `import` that
action and use it in another module.
To tackle that, this PR changes how that works as described in
`server/27/output.js`.
Closes NEXT-2140
This PR stabilizes the previously introduced experimental config options
for providing a custom cache handler (for both ISR as well as the Data
Cache) and for disabling or configuring the in-memory cache size. The
example usage would be as follows:
```js
// next.config.js
module.exports = {
cacheHandler: require.resolve('./cache-handler.js'),
cacheMaxMemorySize: 0 // disable default in-memory caching
}
```
This PR also updates the documentation to better reflect how to use the
custom cache handler when self-hosting. Further information will be
added in a following PR that also includes a full example of a custom
cache handler that implements `revalidateTag` as well as passing in
custom cache tags. The API reference docs have been updated here, as
well as a version history added.
I also noticed that we currently have two duplicated versions of the ISR
docs in the Pages Router docs: both for rendering and for data fetching.
Data Fetching is the correct location for this page. There were no other
references to the rendering version in the docs, so that must have been
an accident. I'll need to a get a redirect going for that regardless.
Tests have been updated for `cacheHandler` and I added a new test for
`cacheMaxMemorySize`.

This reapplies the `experimental.missingSuspenseWithCSRBailout` option
to bail out during build if there was a missing suspense boundary when
using something that bails out to client side rendering (like
`useSearchParams()`). See #57642
Closes [NEXT-1770](https://linear.app/vercel/issue/NEXT-1770)
The following spans are either added or displayed by default:
* `NextNodeServer.findPageComponents` - page components
resolution/require
* `NextNodeServer.getLayoutOrPageModule` - load modules (webpack or
turbopack)
This would allow different apps to setup fetch instrumentation similar
to `@opentelemetry/instrumentation-http` and
`@opentelemetry/instrumentation-fetch` without duplicating fetch spans
and avoiding confusion with context propagation.
This ensures when a dependency has a recursive require our should ignore
handling doesn't accidentally loop back and forth.

As Barrel Optimization might split one file into multiple different
modules, i.e. when you import different values from it, the target file
might be transformed differently, we can no longer rely on the file path
as the identifier of the client reference.
This fix adds a suffix (`'@' + this._module.matchResource`) to the
identifier so it looks like
`/filepath/file.js@__barrel_optimize__?names=Foo`.
Here's also a quick diagram to explain:
Closes#59804.
Closes NEXT-2108.

- Both the standalone server and the `startServer` function it calls
attempt to stop the server on `SIGINT` and `SIGTERM` in different ways.
This lets `server.js` yield to `startServer`
- The cleanup function in `startServer` was not waiting for the server
to close before calling `process.exit`. This lets it wait for any
in-flight requests to finish processing before exiting the process
- Sends `SIGKILL` to the child process in `next dev`, which should have
the same effect of immediately shutting down the server on `SIGTERM` or
`SIGINT`
fixes: #53661
refs: #59551
------
Previously #59551 attempted to fix#53661, but had broken some tests in
the process. It looks like the final commit was also missing an intended
change to `utils.ts`. This should fix those issues as well as introduce
a new set of tests for the graceful shutdown feature.
In the last PR I was squashing and force-pushing updates along the way
but it made it difficult to track the changes. This time I'm pushing
quite a few commits to make it easier to track the changes and refactors
I've made, with the idea that this should be squashed before being
merged.

### What
Sometimes the display of the error overlay is not consistent even when
you fixed the error
Example:
* You have a client page, and you add metadata export, Next.js will
error that it's not allowed in client component.
* You fix it, but the error overlay is not disappeared. Or you fix it,
then introduce it again, then fix it again, the error overlay is still
there.
### How
We're checking if the HMR webpack hash is changed to decide if we're
going to do a hot update in `BUILT` and `SYNC` event, but we update the
hash at the very beginning of the event handler. `isUpdateAvailable()`
will return `false` in the later calls but the hash has already changed
before. So we check if they change before applying hot updates, and then
use it later with `isUpdateAvailable()` to determine if necessary to
process a new hot update

## What?
Updates snapshots for Turbopack tests. They're slightly different than
the webpack output. Generally better because column information is
preserved. The import trace is not available in Turbopack as it would
make the parent module a direct dependency of the module, meaning it
would have to recompile every time you can the parent module. We'll
figure out if it can be added in a different way at a later point.

When you're using `noStore()` with `fetch` it's currently saying "auto
cache" in cache missed reason, adding "noStore call" here to show it's
caused by using with `unstable_noStore`
```
GET /no-store 200 in 4069ms

### What
We're applying react-refresh to browser layer and inject ESM or CJS
helper based on file type. Some package from `trasnpilePackages` might
contain CJS browser bundle. And injecting ESM helper breaks them.
Actually they don't need to have fast refresh ability since they're in
`node_modules`.
### How
Skip react-refresh for transpiled packages as they're in node_modules
and won't change.
Fixes#56487
Closes NEXT-2061
### Depends on
- #60577
---
A popstate navigation reads data from the local cache. It does not issue
new network requests (unless the cache entries have been evicted). So,
when navigating with back/forward, we should not switch back to the PPR
loading state. We should render the full, cached dynamic data
immediately.
To implement this, on a popstate navigation, we update the cache to drop
the prefetch data for any segment whose dynamic data was already
received. We clone the entire cache node tree and set the `prefetchRsc`
field to `null` to prevent it from being rendered. (We can't mutate the
node in place because Cache Node is a concurrent data structure.)
Technically, what we're actually checking is whether the dynamic network
response was received. But since it's a streaming response, this does
not mean that all the dynamic data has fully streamed in. It just means
that _some_ of the dynamic data was received. But as a heuristic, we
assume that the rest dynamic data will stream in quickly, so it's still
better to skip the prefetch state.
Closes NEXT-2084
### What?
Throwing a `notFound()` error inside of a segment that has an error
boundary will cause it to be handled by the segment's error boundary
rather than a parent not-found boundary.
### Why?
We assume anything that hits an `ErrorBoundary` is an actual error, but
this should not be the case when the caught error is one that is handled
by Next.js.
### How?
This checks if the caught error is one that is expected to be handled
someplace else.
