### What?
This ensures that the body limit option is enforced on all request
bodies sent to the Node.js runtime, not just the multipart field size
limits.
### Why?
The documentation states that this should limit the body size,
previously it only limited the field size.
### How?
This uses a `Transform` stream from Node.js. [Based on my
benchmarks](https://gist.github.com/wyattjoh/c470d98095da2f95f5920396aba2a206)
using the transform stream added next to no overhead, yet it did
simplify the implementation quite a bit. Assuming this is due to the
already performant stream support within Node.js.
Closes NEXT-3151
When a server action triggers a redirect, we're incorrectly applying a
refresh marker to the segment they were on, rather than the segment they
were being redirected to. As a result, when revalidation occurs (via
`revalidateX` or `router.refresh()`), the top-level segment would be
replaced with data for an incorrect segment.
For example, if triggering a redirect action from `/redirect` to `/`,
the router state tree would save a reference to `/redirect`. The next
time a refresh or revalidate happens, it'd refresh the segment data for
`/redirect` instead of `/`.
Fixes#64728
Closes NEXT-3156
## What?
In the past folks on the team have reported that anytime the SWC /
Turbopack binary changes they had to suddenly run `pnpm build-native` in
`packages/next-swc`, even though they didn't build from source before.
While investigating optimizing packing for tests I found that it's
copying the native binary into the original repository not the temporary
repository, which then keeps the file there, even after the tests
finish. This fixes the path to use the tmp repository instead.

Closes NEXT-3157
When the router cache can't find a cache node for the requested segment,
it performs a request to the server to get the missing data. This
request to the server currently will always include the `next-url`
header, and on soft-navigations, the router will route the request to
the intercepted handler. This lazy fetch is treated as a soft navigation
by the server, and will incorrectly return data for the intercepted
route.
Similar to the handling in `router.refresh`, and the server action
reducer, we should not include the `next-url` header if there's no
interception route currently in the tree, as otherwise we'll be
erroneously triggering the intercepted route.
Fixes#64676
Closes NEXT-3146
Reverts vercel/next.js#64271
This appears to be causing problems rendering error boundaries on SPA
navigations and needs further investigation
Closes NEXT-3150
### Why
If you have a client entry that mixing `default` re-export and `*`
re-export, atm we cannot statically analyze all the exports from this
the boundary, unless we can apply barrel file optimization for every
import which could slow down speed.
```js
// index.js
'use client'
export * from './client'
export { default } from './client'
```
Before that happen we high recommend you don't mixing that and try to
add the client directive to the leaf level client module. We're not able
to determine what the identifiers are imported from the wildcard import
path. This would work if we resolved the actual file but currently we
can't.
### What
When we found the mixing client entry module like that, we treat it as a
CJS client module and include all the bundle in client like before what
we have the client components import optimization.
Ideally we could warn users don't apply the client directive to these
kinda of barrel file, and only apply them to where we needed.
Fixes#64518
Closes NEXT-3119
## Info
I did not create a GitHub issue, but this PR for fixing the issue. Hope
that's okay.
## The bug
We run a 'normal' custom server described here:
https://nextjs.org/docs/pages/building-your-application/configuring/custom-server
```ts
const next = require('next');
const dev = process.env.NODE_ENV !== 'production';
const port = 3000;
const app = next({ dev, port, quiet: !dev })
const handle = app.getRequestHandler()
// ...
```
The `quiet` settings is missed in some deeper Next.js internal api
calls. For that reason, the setting did not work at all. This works only
in production mode.
## Testing
I tried to implement a test in `/test/production/custom-server` but I
failed to get the `stderr` messages. When someone give me some guidance,
I will add a new test.
Here are some criteria:
- need: custom server with `quiet: true` setting
- need: a next.js page with thrown error. e.g. `export const
getServerSideProps = () => { throw new Error('failed') }`
- need: collect all `stderr` messages
I tested the fix in our project by editing the files in `node_modules`
-- it worked.
## Background
We upgrade our project from next `13.3.4` to `14.2.0` and saw this
regression. I can not tell in which version this bug was added. We run a
Next.js + 'custom server' + Docker setup. Because we have a lot of
traffic, we need to suppress the standard Next.js logging and using our
own logging.

## What?
- Changes webpack output target to `es6` (required for `async function`
output)
- Adds tests for top level await in server components and client
components (App Router)
- Converted the async-modules tests to `test/e2e`
- Has one skipped test that @gnoff is going to look into. This shouldn't
block merging this PR 👍
Adds additional tests for top level `await`.
Since [Next.js
13.4.5](https://github.com/vercel/next.js/releases/tag/v13.4.5) webpack
has top level await support enabled by default.
Similarly Turbopack supports top level await by default as well.
TLDR: You can remove `topLevelAwait: true` from the webpack
configuration.
In writing these tests I found that client components are missing some
kind of handling for top level await (async modules) so I've raised that
to @gnoff who is going to have a look.

### How?
Closes NEXT-

Closes NEXT-3126
Fixes https://github.com/vercel/next.js/issues/43382
### Why
For app page rendering on edge, the `AsyncLocalStorage` (ALS) should be
bundled as same instance across layers. We're accessing the ALS in
`next/dynamic` modules during SSR for preloading CSS chunks. There's a
bug that we can't get the ALS store during SSR in edge, I digged into it
and found the root cause is:
We have both import paths:
`module (rsc layer) -> request ALS (shared layer)`
`module (ssr layer) -> request ALS (shared layer)`
We expect the ALS to be the same module since we're using the same layer
but found that they're treated as different modules due to applying
another loader transform on ssr layer. They're resulted in the same
`shared` layer, but with different resource queries. This PR excluded
that transform so now they're identical across layers.
### What
For webpack, we aligned the loaders applying to the async local storage,
so that they're resolved as the same module now.
For turbopack, we leverage module transition, sort of creating a new
`app-shared` layer for these modules, and apply the transition to all
async local storage instances therefore the instances of them are only
bundled once.
To make the turbopack chanegs work, we change how the async local
storage modules defined, separate the instance into a single file and
mark it as "next-shared" layer with import:
```
any module -> async local storage --- use transition, specify "next-shared" layer ---> async local storage instance
```
Closes NEXT-3085
### What
When rendering a parallel slot multiple times in a single layout, in
conjunction with using an error boundary, the following TypeError is
thrown:
> Cannot destructure property 'parallelRouterKey' of 'param' as it is
null
### Why
I'm not 100% sure of the reason, but I believe this is because of how
React attempts to dededupe (more specifically, "detriplficate") objects
that it sees getting passed across the RSC -> client component boundary
(and an error boundary is necessarily a client component). When React
sees the same object twice, it'll create a reference to that object and
then use that reference in future places where it sees the object. My
assumption is that there's a bug somewhere here, as the `LayoutRouter`
component for the subsequent duplicated parallel slots (after the first
one) have no props, hence the TypeError.
### How
Rather than passing the error component as a prop to `LayoutRouter`,
this puts it as part of the `CacheNodeSeedData` data structure. This is
more aligned with other properties anyway (such as `loading` and `rsc`
for each segment), and seems to work around this bug as the
`initialSeedData` prop is only passed from RSC->client once.
EDIT: Confirmed this is also fixed after syncing the latest React, due
to https://github.com/facebook/react/pull/28669Fixes#58485
Closes NEXT-2095
`initialCanonicalUrl` differs from the `canonicalUrl` that gets set on
the client, such as when there's a basePath set.
This hoists the `canonicalUrl` construction up so we can re-use it when
adding refetch markers to the tree.
This also renames `pathname` -> `path` since it also includes search
params. I added a test to confirm no extra erroneous fetches happened in
both cases.
Fixes#64584
Closes NEXT-3130
Since `AppRouterState` is promise-based (so we can `use` the values and
suspend in render), the state itself isn't stable between renders. Each
action corresponds with a new Promise object. When a link is hovered, a
prefetch action is dispatched, even if the prefetch never happens (for
example, if there's already a prefetch entry in the cache, and it
doesn't need to prefetch again). In other words, the prefetch action
will be dispatched but won't necessarily change the state.
This means that these no-op actions that don't actually change the state
values will trigger a re-render. Most of the context providers in
`AppRouter` are memoized with the exception of `LayoutRouter` context.
This PR memoizes those values so that consumers are only notified of
meaningful updates.
Fixes#63159
Closes NEXT-3127
### What
When middleware.js is present, the logging is duplicated. We should
filter out the 1st middleware request and only log the actual one going
through request handler / renderer
Closes NEXT-3125
When an action is marked as "discarded", we enqueue a refresh, since the
navigation event will be invoked immediately without waiting for the
action to finish. We refresh because it's possible that the discarded
action triggered some sort of mutation/revalidation, and we want the
router to still be able to respond to that new data.
However there's a bug in this logic -- it'll only enqueue the refresh
action if there were no other actions in the queue, ignoring the case
where something is still in the queue. This makes sure that the refresh
is handled after `runRemainingActions` finishes.
When adding a test for the server component case (which doesn't hit this
refresh branch), I noticed `LayoutRouter` caused React to suspend
indefinitely, because it got stuck in the `use(unresolvedThenable)`
case. We should only suspend indefinitely if we kicked off a the
`SERVER_PATCH` action, as otherwise it's possible nothing will ever
break out of that branch.
Fixes#64517
Closes NEXT-3124
## What
Determine if the client module is a CJS file and `default` export is
imported, then we include the whole module instead of using webpack
magic comments to only extract `default` export.
## Why
Unlike ESM, The `default` export of CJS module is not just `.default`
property, we need to include `__esModule` mark along with `default`
export to make it function properly with React client module proxy
Fixes#64518
Closes NEXT-3119
### What
This PR's goal is to improve the throughput performance of the Next.js
server when handling Pages Router routes.
Note that the results from this are very synthetic and do not represent
the real-life performance of an application. If we only wanted to handle
hello worlds, we could probably make this even faster but on production,
a slow fetch call to your DB is probably what's slowing you down.
I'll look into App Router next.
### Why?
I guess I got nerd-sniped into it 😃
### How?
A few optimizations:
- I looked deeply at the pipeline for rendering a Pages Router page. I
noticed a lot of intermediary streams being created here and there to
eventually be concatenated to a simple string. I think this is probably
left over code from when we wanted to support streaming there and so
there's some code that was shared with the App Router, which we
absolutely don't need I think. I refactored it to be slightly simpler
with just a few string concats here and there.
- misc: I removed some redundant Promises being created here and there
and added a small inline optimisation to eliminate `if (renderOpts.dev)`
code in production.
### Nummies
Test setup: hello world pages router app, next start + autocannon
- requests handled in 10s: 18k -> 33K, **~80% improvement**
- avg latency: 4.89ms -> 2.8ms, **~42% improvement**
- avg req/res: 1846.5 -> 2983.5, **~61% improvement**

### Summary
Fixes#52935
`next/script` has a `Script` component that supports an `async` prop.
However, when scripts are loaded with the `async` prop set to false, the
script is loaded as if async was set to true. This may cause scripts to
execute out of order. Repro:
https://github.com/domdomegg/next-async-script-reproduction
I think this is occurring because Next uses setAttribute to set the
async and defer attributes. However, this is not a valid way to set
these properties on a script. This is because . Demo:
https://jsfiddle.net/6ktpfae1/
This PR fixes this behaviour by using removeAttribute after calling
setAttribute (rather than using setAttribute "false"). This appears to
result in correct behaviour.
Given it appears this workaround was already applied in `next/head`,
I've harmonised the code between these two.
### Next steps
I think this PR is ready for review. I acknowledge there are no test
changes, but there are no existing tests for `next/script` at all and
creating them I think would be disproportionally difficult given issues
in #52943.

### What?
The string value of `Metadata.openGraph.emails` throws error:
```tsx
export const metadata = {
openGraph: {
type: 'article',
emails: 'author@vercel.com',
},
};
```
Error:
```sh
r.map is not a function
```
The type is:
```tsx
type OpenGraphMetadata = {
// ...
emails?: string | Array<string>
}
```
### Why?
Basic values such as `emails` and `phoneNumbers` were not included when
`ogType` was set while resolving the values.
### How?
Include basic values when resolving the metadata.
Fixes#63415
This ensures we properly skip calling a fetch during build-time that has
`cache: 'no-store'` as it should only be called during runtime instead.

Closes NEXT-3114
## Why?
For multi-root layouts (route groups on the root with their root
layouts, no layout file on the root), it is not possible to use global
`not-found` since the `layout` is missing on the root.
```sh
.
└── app/
├── (main)/
│ └── layout.js
├── (sub)/
│ └── layout.js
└── not-found.js --> ERR: missing layout
```
Current Behavior:
```sh
not-found.js doesn't have a root layout. To fix this error, make sure every page has a root layout.
```
## What?
Let multi-root layouts also benefit from the global `not-found`.
## How?
Wrap root `not-found` with default layout if root layout does not exist.
Although this solution is not `multi-root` specific, it won't produce
critical issues since a root `layout` is required for other cases.

### 🤔 What's in there?
We've deprecated config's `analyticsId` in 14.1.1 [almost 3 months
ago](https://github.com/vercel/next.js/releases/tag/v14.1.1-canary.2).
Users can opt in fot `@vercel/speed-insights`, or use
`useReportWebVitals` to report to any provider they'd like.
This PR:
- removes `analyticsId` key from configuration
- stops setting `__NEXT_PUBLIC_ANALYTICS_ID` env variable when the key
was present
- stops injecting `performance-relayer` file, when the variable is set
- cleans up related test code.
### What
Inherit the client boudaries from the found matched target in load
barrel
### Why
The root cause with the barrel transform, we missed the client boundary
directive during the transform.
Since the new version of mui's case looks like this:
Import path
page.js (server module) -> `<module>/index.js` (shared module) ->
`<module/subpath>/index.js` (client module) ->
`<module/subpath/sub-module.js> (client module)
After our transform, we lost the `"use client"` which causes the
mismatch of the transform:
In `rsc` layer: the file pointing to the sub module entry
(`<module/subpath>/index.js`), but without the client boundary.
Fixes#64369
Closes NEXT-3101
Since the router processes events sequentially, we special case
`ACTION_NAVIGATE` events to "discard" a pending server action so that it
can process the navigation with higher priority. We should apply this
same logic to `ACTION_RESTORE` events (e.g. `router.back()`) for the
same reason.
Fixes#64432
Closes NEXT-3098
`fetchCache` is a more fine-grained segment level cache-control
configuration that most people shouldn't have to use. Current semantics
of `dynamic = "force-dynamic"` will still treat the fetch as cacheable
unless explicitly overriding it in the fetch, or setting a segment level
`fetchCache`.
The `dynamic` cache configuration should be seen as a "top-level"
configuration, while more fine-grained controls should inherit logical
defaults from the top-level. Otherwise this forces people to opt-into
the `fetchCache` configuration, or manually override each `fetch` call,
which isn't what you'd expect when forcing a segment to be dynamic.
This will default to not attempting to cache the fetch when
`force-dynamic` is used. As a result, I had to update one of the
`app-static` tests to use `revalidate: 0` rather than `force-dynamic`,
as the revalidate behavior is slightly different in that it won't modify
the revalidation time on a fetch if it's non-zero.
Closes NEXT-2067
The fix is not correct, we already have request ALS wrapping the request
in app-render, shouldn't get another one for edge adapter. This is
actually a bundler bug
Reverts vercel/next.js#64382
Closes NEXT-3097
### What
Wrap async local storage for all edge runtime routes in adapter
Basically fixed the case reported in [this
tweet](https://x.com/keegandonley/status/1778538456458854880)
### Why
We're relying on the ALS for dynamic css preloading but we didn't wrap
the ALS for request handlers for edge. So if you have CSS imports in
`next/dynamic` in edge runtime it would break.

### What?
### Why?
### How?
Closes NEXT-
Fixes #
-->
### What?
This adds a missing test case for a page which accesses dynamic API's
within `generateMetadata`. It also adds a test case to verify that any
of the URL's being tested can succeed based on the components link
components (it relies on finding a link to click in the browser).
Closes NEXT-3004
## Why
Currently, Server Action handlers are just normal routes and they
accepting POST requests. The only way to differentiate a normal request
(page access, API route, etc.) from a Server Action request is to check
that if it's a POST and has a Server Action ID set via headers or body
(e.g. `multipart/form-data`).
Usually, for existing page and API routes the correct handlers (page
renderer, API route handler) will take precedence over Server Action's.
But if the route doesn't exist (e.g. 404) it will still go through
Server Action's handler and result in an error. And we're eagerly
logging out that error because it might be an application failure, like
passing a wrong Action ID.
## How
In this PR we are making sure that the error is only logged if the
Action ID isn't `null`. This means that it's an intentional Server
Action request with a wrong ID. If the ID is `null`, we just handle it
like 404 and log nothing.
Fixes#64214.
Closes NEXT-3071
### What
Bump the edge runtime manifest version and add `environments` property
to each route for inlining values for deployment build.
### Why
In edge runtime, extract the preview props into edge functions manifest
that holding the non-deterministic inline values, then the output build
will be more deterministic that helps deployment speed

### What?
This adds a script that first gets a list of changed files compared to
our base branch (`canary`) in PRs and identifies related test files by
looking them up from a `related-tests-manifest.json`, then runs them.
### Why?
We would like to be able to run related E2E tests when certain files
change, so we can test deployment stability.
NOTE: We still want to run all E2E tests on PRs, but this script can be
used to also test deployments for hot paths. Since these tests can take
up to [3-4
hours](https://github.com/vercel/next.js/actions/workflows/test_e2e_deploy.yml),
we aim to run a subset of these tests first.
Closes NEXT-2947
Building on #58293, this expands escaping of url-unsafe characters in
paths to “required” scripts and styles in the app renderer.
This also refactors the test introduced in #58293 and expands it to
include stylesheet references as well as checking resources in the head,
which include special characters like turbopack references like
`[turbopack]`.
Test Plan: `TURBOPACK=1 pnpm test-dev
test/e2e/app-dir/resource-url-encoding`
Closes PACK-2911
### What
CSS imports in components that loaded by `next/dynamic` in client
components will cause the css are missing initial in
SSR, and loaded later on client side which will lead to FOUC. This PR
fixes the issue and get CSS preloaded in the SSR for dynamic components.
### Why
The CSS from client components that created through `next/dynamic` are
not collected in the SSR, unlike RSC rendering we already collect the
CSS resources for each entry so we included them in the server rendering
so the styles are availble at that time. But for client components, we
didn't traverse all the client components and collect the CSS resources.
In pages router we kinda collect all the dynamic imports and preload
them during SSR, but this approach is not able to be applied to app
router due to different architecture. Since we already have all the
dynamic imports info and their related chunks in
react-loadable-manifest, so we can do the similar "preloading" thing in
app router. We use the current dynamic module key (`app/page.js ->
../components/foo.js`) which created by SWC transform and match it in
the react loadable manifest that accessed from `AsyncLocalStorage`, to
get the css files created by webpack then render them as preload
styleshee links. In this way we can SSR all the related CSS resources
for dynamic client components.
The reason we pass down the react loadable manifest through
`AsyncLocalStorage` is that it's sort of exclude the manifest from RSC
payload as it's not required for hydration, but only required for SSR.
Note: this issue only occurred in dynamic rendering case for client
components.
### Other Changes Overview
- Change the react loadable manifest key from pages dir based relative
path to a source dir based relative path, to support cases with both
directory or only one of them
Closes NEXT-2578
Fixes#61212Fixes#61111Fixes#62940
Replacement for #64021 but only with production test
Provides a `revalidateReason` argument to `getStaticProps` ("stale" |
"on-demand" | "build").
- Build indicates it was run at build time
- On-demand indicates it was run as a side effect of [on-demand
revalidation](https://nextjs.org/docs/pages/building-your-application/data-fetching/incremental-static-regeneration#on-demand-revalidation)
- Stale indicates the resource was considered stale (either due to being
in dev mode, or an expired revalidate period)
This will allow changing behavior based on the context in which it's
called.
Closes NEXT-1900
## Why?
When we fetch the same cache key (URL) but add an additional tag, the
revalidation does not re-fetch correctly (the bug just uses in-memory
cache again) when deployed.

### What
When submitting a server action on a page that doesn't import the action
handler, a "Failed to find server action" error is thrown, even if
there's a valid handler for it elsewhere.
### Why
Workers for a particular server action ID are keyed by their page
entrypoints, and the client router invokes the current page when
triggering a server action, since it assumes it's available on the
current page. If an action is invoked after the router has moved away
from a page that can handle the action, then the action wouldn't run and
an error would be thrown in the server console.
### How
We try to find a valid worker to forward the action to, if one exists.
Otherwise it'll fallback to the usual error handling. This also adds a
header to opt out of rendering the flight tree, as if the action calls a
`revalidate` API, then it'll return a React tree corresponding with the
wrong page.

### What
We introduced a new algorithm to find the matched hydration error tags,
when there're two tags indicating children and parent as bad descendence
relationship. Now we search for the child first from the last index, and
then from found child to search its above parent. This way we can find
the two related tags in O(1), since they could be not directly nested.
### Why
When a hydration error occurred, such as bad nesting `div` under `p`,
one of the tag `div` is matched multiple times in the component stack,
it shouldn't be highlighted multiple times. This PR fixes the bad
matching about multiple nested tags, e.g. when there're many `div` tag
and `div` is one of the bad tag, only the one directly under p should be
highlited.
Case
```
Page > div > div > p > div
```
Current Result: all `div` and `p` get highlighted, `[]` represents
highlighted.
```
Page > [div] > [div] > [p] > [div]
```
Expected: only the related 2 tags are highlighted, `[]` represents
highlighted.
```
Page > div > div > [p] > [div]
```

### What?
Emit `<link data-next-font="size-adjust" rel="preconnect" href="/"
crossorigin="anonymous"/>` in more cases.
### Why?
To align with the default mode
### How?
## What?
When creating the Next.js instance fails for whatever reason (most
commonly `next build` failing) it currently exits the process, this
causes Jest to not report these tests as failed.
The change in this PR ensures that anytime creating the instance fails
it throws an error that is caught by Jest and then causes Jest to report
the tests as failed.
The reporting of tests is relevant as our monitoring tools (i.e. DataDog
/ Turbopack test manifest) rely on correct reporting of all failing
tests.

Closes NEXT-3016
When adding refresh markers for refetching segments that are "stale"
(the soft navigation case where they are still in the Router State Tree
but not part of the page that we're rendering), they only contained a
reference to the pathname. Once the actual refresh was triggered we
added the current search params to the request.
However, this causes an issue: segments in the `FlightRouterState` can
contain searchParams (ie, `__PAGE__?{"foo": "bar}` is what the segment
becomes when adding `?foo=bar` to a page). This means that when we
refresh those nodes from the server, it won't know how to find the
`CacheNode` for the stale segment since we won't have them in the
refetch tree. This updates to keep a reference to the searchParams that
were part of the request that made it active.
While fixing this, I also noticed that we were missing a spot to add the
refetch marker in `applyRouterStatePatchToTree` in the case of a root
refresh (caught by these tests failing in PPR)

### What
When triggering an interception route that has a parent with dynamic
params, and then later going to "refresh" the tree, either by calling
`router.refresh` or revalidating in a server action, the refresh action
would silently fail and the router would be in a bad state.
### Why
Because of the dependency that interception routes currently have on
`FlightRouterState` for dynamic params extraction, we need to make sure
the refetch has the full tree so that it can properly extract earlier
params. Since the refreshing logic traversed parallel routes and scoped
the refresh to that particular segment, it would skip over earlier
segments, and so when the server attempted to diff the tree, it would
return an updated tree that corresponded with the wrong segment
(`[locale]` rather than `["locale", "en", "d]`).
Separately, since a page segment might be `__PAGE__?{"locale": "en"}`
rather than just `__PAGE__`, this updates the refetch marker logic to do
a partial match on the page segment key.
### How
This keeps a reference to the root of the updated tree so that the
refresh always starts at the top. This has the side effect of
re-rendering more data when making the "stale" refetch request, but this
is necessary until we can decouple `FlightRouterState` from interception
routes.

Fixes: https://github.com/vercel/next.js/issues/63481
Closes NEXT-2984
Closes NEXT-2904
Trying to submit a server action when JS is disabled (ie, no action
header in the request, and in the "progressively enhanced" case) for a
static resource results in a 405 error when deployed to Vercel. In the
absence of an action ID header, the request content-type is used to
signal that it shouldn't try and hit the static cache. However with
multipart/form-data, this will include the boundary. This updates the
matcher to consider a boundary string.
Fixes#58814
Closes NEXT-2980
This introduces an experimental router flag (`experimental.staleTimes`)
to change the router cache behavior. Specifically:
```ts
// next.config.js
module.exports = {
experimental: {
staleTimes: {
dynamic: <seconds>,
static: <seconds>,
},
},
};
```
- `dynamic` is the value that is used when the `prefetch` `Link` prop is
left unspecified. (Default 30 seconds)
- `static` is the value that is used when the `prefetch` `Link` prop is
`true`. (Default 5 minutes)
Additional details:
- Loading boundaries are considered reusable for the time period
indicated by the `static` property (default 5 minutes)
- This doesn't disable partial rendering support, **meaning shared
layouts won't automatically be refetched every navigation, only the new
segment data**.
- This also doesn't change back/forward caching behavior to ensure
things like scroll restoration etc still work nicely.
Please see the original proposal
[here](https://github.com/vercel/next.js/discussions/54075#discussioncomment-6754339)
for more information. The primary difference is that this is a global
configuration, rather than a per-segment configuration, and it isn't
applied to layouts. (We expect this to be a "stop-gap" and not the final
router caching solution)
Closes NEXT-2703
### What?
Match on `/_next/static/chunks/%5Broot%20of%20the%20server%5D__` instead
of `/_next/static/chunks/main` while testing.
### Why?
Turbopack does not use `/_next/static/chunks/main` as the name of the
chunk
### How?
Closes PACK-2874

### What?
This fixes an issue where the `nonce` attribute isn't set on
`next/script` elements that has the `afterInteractive` (the default)
strategy resulting in `<link rel="preload" as="script"/>` tags without a
nonce.
### Why?
For apps that uses 3rd party scripts (or any script) with a nonce loaded
via `next/script` this is necessary unless you want them all to use
`beforeInteractive` which isn't super nice for performance.
---------
Co-authored-by: JJ Kasper <jj@jjsweb.site>
### What & Why
There was some code added in the catch-all route normalization that
doesn't seem to make sense -- it was checking if the provided `appPath`
depth was larger than the catch-all route depth, prior to inserting it.
But it was comparing depths in an inconsistent way (`.length` vs
`.length - 1`), and the catch all path was also considering the `@slot`
and `/page` suffix as part of the path depth.
This means that if you had a `@modal/[...catchAll]` slot, it wouldn't be
considered for a page like `/foo/bar/baz`, because `/foo/bar/baz`
(depth: 4 with the current logic) and `/@modal/[...catchAll]/page`
(depth: 3 with the current logic) signaled that the `/foo/bar/baz` route
was "more specific" and shouldn't match the catch-all.
I think this was most likely added to resolve a bug where we were
inserting optional catch-all (`[[...catchAll]]`) routes into parallel
slots. However, optional catch-all routes are currently unsupported with
parallel routes, so this feature didn't work properly and the partial
support introduced a bug for regular catch-all routes.
### How
This removes the confusing workaround and skips optional catch-all
segments in this handling. Separately, we can add support for optional
catch-all parallel routes, but doing so will require quite a bit more
changes & also similar handling in Turbopack. Namely, if have a
top-level optional catch-all, in both the Turbopack & current Webpack
implementation, that top-level catch-all wouldn't be matched. And if you
tried to have an optional catch-all slot, in both implementations, the
app would error with:
> You cannot define a route with the same specificity as a optional
catch-all route ("/" and "/[[...catchAll]]")
because our route normalization logic does not treat slots specificity
differently than pages.
**Note**: This keeps the test that was added when this logic was first
introduced in #60776 to ensure that the case this was originally added
for still passes.
Fixes#62948
Closes NEXT-2728
## 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.

### 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
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.

Supports root segment config inherit from layout. Currently route

### What
In static generation phase of app page, if there's any case that we're

### 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.

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.

Closes NEXT-2915
### 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.
Fixes#59999
Fixes NEXT-2738
### 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.
Closes PACK-2804
This causes Turbopack to fail and communicate when a file with an
unhandled or unregistered extension is built.

### What?
route/middleware/instrumentation use server assets
server assets use full url rewrite
### Why?
### How?
https://github.com/vercel/turbo/pull/7750
Fixes PACK-2522
fixes PACK-2645
### 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!**
Fixes#60844Fixes#62470
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.

Closes NEXT-2825
### What
Implement webpack's middleware plugin equivalent for webpack, to raise
unsupported error in runtime.
PR utilizes import map alias for the edge context, to resolve into
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

* special chunking for CSS with loose and strict mode
* more test cases

`pages/_app.js`
### Why?
To make turbopack match behavior of webpack mode, and make the test

### 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.
### Why?
### Turbopack Changes

### 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.

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

`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.

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.

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.

## 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
(Dark and light modes)
#### Mismatch html tags

#### 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.
Fixes#61384
Closes PACK-2487
## What?
#62528 caused test/e2e/app-dir/not-found/conflict-route to fail
compilation in Turbopack, this compiler error was previously already
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.
Closes NEXT-2617

https://github.com/vercel/next.js/pull/62585 which wasn't sufficient.

### 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.

Closes NEXT-2621
### 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
to prevent regression.

### 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
Closes NEXT-2439
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.
Closes: CSM-11
Fixes: https://github.com/vercel/next.js/issues/19270
Closes NEXT-2613
### 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
Fixes#62407
### 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
Error: Could not find a production build in the '.next' directory. Try building your app with 'next build' before starting the production server. https://nextjs.org/docs/messages/production-start-no-build-id

at Server.<anonymous> (/home/flotwig/src/next.js/packages/next/src/server/lib/start-server.ts:295:28)
```
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
Closes NEXT-2519

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:
```

```
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)

## Description
We need to manually update the `@capsizecss/metrics` every time it
updates so we get the latest fallback fonts.
## Changes
- https://github.com/vercel/next.js/issues/47115
Closes NEXT-2547
### What
This PR amends turbopack's behavior to handle some cases of normalized
path (`%5F` starting path), mainly fixes entry lookup works against
original path without normalization, also bends the output path of
client reference manifest matchs to what next.js expects.
Closes PACK-2553
This adds a new span to allow tracking the sum of all client component
loading times for a specific request along with the count of items
loaded.

## What?
Groups together the scss tests. I'm working on refactoring these to use
`test/e2e` instead as many tests currently only run during builds and we
want to make sure these Sass tests run for Turbopack (which is dev only
currently) to catch bugs.

Closes NEXT-2536
### 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:

### What?
The [create-next-app
documentation](https://nextjs.org/docs/app/api-reference/create-next-app#non-interactive)
under API reference says that;
> Further, you can negate default options by prefixing them with --no-
(e.g., --no-eslint).
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.

### Why?
We currently use `page` and `pathname` in different places for file
system paths (manifests can be in a different folder to the js entry),
this PR makes more things just use `page` directly instead of going
through `pathname`.
This PR also adds an entry key (similar to the webpack version) uniquely
identifying all entry points (and assets).
Closes PACK-2432
### What?
An unactionable error is thrown when `headers()`, `cookies()` or other
Dynamic API functions are called outside the render/request context.
This PR clarifies what the user can do to fix the problem.
### Why?
The current error is hard to understand
> Error: Invariant: `cookies` expects to have requestAsyncStorage, none
available.
### How?
I am adding a dedicated error page and rephrasing the error message.

### 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.
### How?
Closes PACK-2408
As discussed almost all webpack plugins shouldn't have issues with this
being enabled by default so removing the default condition where we
disable this optimization due to custom webpack config is more
beneficial and in the rare case a custom plugin has issues it can still
be manually disabled.
Closes NEXT-2523
### What?
* add support for esmExternals in pages
* fix default of esmExternals to true
* fix serverComponentExternalPackages support
* add test case
fixes PACK-2311
fixes PACK-1916
Fixes https://github.com/vercel/turbo/issues/4544
### 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?
Closes PACK-2414
### 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
