When conflicted pages occur between app and pages server used to throw error and you need to solve the conflicts and restart the server.
This PR capture the error during files aggregation, and send to client to display the error for files confliction. This will send all the conflicts to client and it will still error until you solve all of them. But since the server is not stuck by errors, client can recover once the error is solved.
Closes NEXT-1283
The next-metadata-route-loader emitted content with `"next/server"` is still using cjs version which is not get tree-shaked on edge runtime, This PR adds a new esm entry for it and mapped it that on edge runtime so unused exports can be tree-shaked. This case happened when users are using ImageResponse from `"@vercel/og"` instead of `"next/server"`.
2nd change is adding another alias to map `@vercel/og` package to vendored og package inside next.js, this way we could merge the two package instead of bundled both of them
Fixes: NEXT-1303
changed `require.reoslve("next/dist/xxx")` to `${NEXT_PROJECT_ROOT}/xxx}` to avoid to be traced by nft.
Continuing on changes to move the rendering logic into the bundles.
- Unifies edge render functions: `appRenderToHTML` and `pagesRenderToHTML` becomes `renderToHTML`
- When an error occurs, the error module's match is used so the module's internal render can be used (easing transition away from using the server's render method)
- Improved test resiliance
### What?
Paths with interception markers adjacent to dynamic segments are not correctly parsed, which leads to the path match logic failing.
### Why?
`getParametrizedRoutes` checks for brackets but isn't expecting to receive an interception marker. For example, a path of `/photos/(.)[author]/[id]` results in the following regex:
`/^\/photos\/\(\.\)\[author\]\/([^/]+?)(?:\/)?$/`
This will not match a path of `/photos/(.)zack/1` since it retained the `[author]` brackets.
`getSegmentParam` has a similar issue when getting values for path params, though we can just skip the interception markers and go straight to the params.
Closes NEXT-1166, NEXT-1013

follow up on #51413 where I kinda forgot to support parsing layout files in sub routes in a parallel segment.
This should fix it by making sure that we check at all level of the app loader tree and by creating an implicit inner `children` for all parallel slot
link NEXT-1301
Currently an "action module" (files with `"use server"` on top) can be
imported by both the server and client layers. In that case, we can't
fork that action module into two modules (one on the server layer, one
on the action layer), but only create it once on the server layer.
This ensures that the action module instance doesn't get forked.
Closes#50801.
fix NEXT-1265
This PR fixes a bug in which the layout files were not picked up if they were direct children of a parallel route slot.
Note: there's a bunch of other files that I've used for debugging that are not used for the test but I'm leaving them for future me.
link NEXT-969
There're 3 layers in the RSC module graph: server → client → action. "Action" means that a Client Component re-enters the server layer by importing a file with `"use server"`, and it should behave the same as the server layer but you can't enter the client layer again (hence we have a 3rd layer name).
Since the action layer has the same behavior and module resolution rules, it should be bundled just like the server layer.
Closes#50658. Originally the issue was that `auth/next` isn't being bundled on the action layer, and it has the async local storage imported. Because of that, that storage comes from node_modules instead of the server bundle.
fix NEXT-1290
Make sure we are using `var` instead of `const` as we always put the new
appended statements to the end of the module body, but they can still be
referenced before in the HOC case in the runtime. This causes a runtime
error.
Tl;dr: `a = 1; var a` is fine, but `a; const a = ...` will result in a
compilation error.
Closes#49344.
Remove the Server CSS manifest and related logic, and use the chunkGroup
CSS files instead for each entry to inject stylesheet links.
Why was that manifest needed in the first place? When implementing CSS
collection for RSC and nested layout initially, we collect CSS imports
at each layer and create corresponding client entries. But then soon got
hit by the problem of duplication and improper tree-shaking. Two layers
can have the same CSS imported so we solved it in a way that "if an
upper layer imports this module, skip it in child layers". Note that
this is deduped by module, so we need to keep the information of "layer
(entry) → CSS modules" somewhere, in a manifest.
Another reason is that we create the client entry before Webpack
optimizes modules, so we can inject the client entry into the same
compilation. But that means the collected client modules from the server
layer are not properly optimized (DCE). **This is a general issue at the
moment that's not specifically related to CSS, although using that
manifest to collect DCE'd info and join the original collected CSS files
with that info temporarily solved it.** That's why I disabled some tests
related to font CSS collection and want to improve it in a more general
way.
Why is that not needed anymore? Main reason is to keep a good balance
between duplication and number of chunks, and delegate the decision to
Webpack's splitChunks plugin. It is not possible to get to a point of 0
duplication unless we ship every CSS module as a single chunk. And since
in #50406 we made the duplication better but at the chunk asset level,
instead of the original module level.
Prior work: #50406, #50610.
### What?
Fixes https://github.com/vercel/next.js/issues/50129
### Why?
The current denormalization of app dir paths doesnt account for the
normalization done in `normalizeAppPath`, causing build log outputs for
certain paths such as anything under a route groups to be incorrect
### How?
There's 2 ways this could be fixed:
1.) Denormalize the app dir paths by reading the
`app-path-routes-manifest.json` and mapping back to the original file
path
2.) (what I chose to do) Normalize the keys of `appBuildManifest`
### Result
App dir paths, including route groups, now have their correct output
size

Similar to tags and paths, when `cookies().set()` is called we have to
invalidate the client router cache as well so routes with
`cookies().get()` will not holding the stale data. This is critical for
auth and other scenarios.
In the future we can have an optimization to only invalidate routes that
actually rely on cookies, similar to paths.
This PR fixes a few reports that we were double fetching when navigating via a link that had prefetch false.
## Context
The bug was happening because we were inadvertently eagerly fetching even if we potentially bailed out of the optimistic navigation, which would then trigger another fetch from going through the regular navigation path.
There's potentially another bug here where we should potentially not bail out of optimistic navigation in the cases reported but we can fix that later.
fix#49844
link NEXT-1287
## What?
While looking at the CPU profile of booting up Vercel's site I noticed
that we call `getPageStaticInfo` a lot. Looking into this more it turns
out `getPageStaticInfo` is currently called for all routes, `pages` and
`app`, even though the data is only being used to keep track of which
routes are edge functions, however, this is already tracked as part of
the build output so this didn't make sense to me. First I tried
commenting out this entire block and all tests were passing, so I
removed it except for middleware as middleware can provide a `matcher`
which does need to be known before compiling the file as of right now.
After that change a different set of tests started failing, specifically
the one that checks if we warn correctly. Interestingly by fixing
`getPageStaticInfo` being called early and for all routes it also caused
these warnings to no longer trigger as there was a case in the manifest
plugin that called `getPageStaticInfo` with less information. Calling
`getPageStaticInfo` there was not needed either as we call
`getPageStaticInfo` at the beginning of the build for each entrypoint so
we already have the information required, it just had to be passed down
so that the manifest plugin could use it.
For Vercel's site this change improves booting the dev server by over 1
second.

When navigating to a route with a hash parameter, the layout router
jumps to the element by scrolling to the node's `offsetTop` value.
However, this will ignore `scroll-padding`, which deviates from browser
behavior.
It looks like this isn't an issue in the pages router which currently
makes use of
[`scrollIntoView`](https://github.com/vercel/next.js/blob/canary/packages/next/src/shared/lib/router/router.ts#L2262).

For RSC server layer so far we bundle all dependencies, ESM format is the better one rather than CJS to analyze and tree-shake out the unused parts. This PR changes pick the condition names that are in ESM format first for server layer.
Also fixes the misorder of condition names of edge runtime, `conditionNames` should only contain either ESM or CJS, previously the main fields are mixed with conditon names which is not expected for webpack, we separate them now.
Since we're picking ESM instead CJS now, the error of require `exports * from` doesn't exist anymore, but if you're using a CJS dependency which require a ESM package, it will error. This is the existing behavior for our webpack configuration but could happen on server layer bundling
Other related changes:
* Imports are hoisted in ESM, so migrate`enhanceGlobals` to a imported module
* Use `...` to pick the proper imports by import expression, and prefer the `react-server` / `edge-light` condition names for corresponding cases
* Remove edge SSR duplicated `middleware` export checking
This makes sure that if `revalidateTag` is called in a Server Action, the client router cache and prefetch cache are invalidated correctly so following navigations won't reuse the cache that might hold stale data.
Similar case for `revalidatePath`. I left a TODO where we can't just invalidate the subtree under the revalidate paths because of current implementation limitations. To ensure correctness, we just do the same as `revalidateTag`.
When twitter metadata is not provided but opengraph metadata is, fill the opengraph basic information for twitter metadata.
Twitter card can't be displayed if there's no information from twitter meta tags, at least the `twitter:card`. We fill the `title` `description` and `images` these 3 overlapped properties from opengraph image so they can be displayed properly

## What?
Anytime you open a Next.js application that doesn't have a `favicon.ico`
you'll notice `/_error` is being compiled because the browser requests
`favicon.ico`. This PR ensures the 404 page is not compiled in
development for that request. It helps a little with compilation speed.

## What?
Recently I've been using these hello-world tests quite often to get the baseline traces out for `pages` and `app`.
Adding them to the repo so that I don't have to recreate / stash them all the time.
This field is no longer needed. Although removing it might cause
unnecessary styles being included that could be tree-shaken potentially,
it solves a more critical issue of missing CSS resources: since now CSS
import can be "hoisted" to its parent entry (e.g. a layout), we can't
simply get all used CSS resources from the "leaf entry" (e.g. a page).
This PR fixes a couple of categories of CSS issues in App Router, that
come from the same root cause.
### 1. Duplicated styles being loaded in different layers
This issue has been described in
https://github.com/vanilla-extract-css/vanilla-extract/issues/1088#issuecomment-1563931144.
If a CSS module (or a global CSS) is referenced in multiple layers (e.g.
a layout and a page), it will be bundled into multiple CSS assets
because each layer is considered as a separate entry.
<img width="1141" alt="CleanShot-2023-05-26-GoB9Rhcs@2x"
src="https://github.com/vercel/next.js/assets/3676859/8e0f5346-ee64-4553-950a-7fb44f769efc">
As explained in that issue, we have to bundle all CSS modules into one
chunk to avoid a big number of requests.
### 2. CSS ordering issues (conflicts)
This is likely causing https://github.com/vercel/next.js/issues/48120.
When the layer-based bundling and ordering logic applies to CSS, it can
potentially cause non-deterministic order. In this example, button A in
the layout should be in blue. However when button B is imported by the
page, button A becomes red. This is an inconsistent experience and can
be hard to debug and fix.

### What?
This test case was never passing and accidentally enabled for Turbopack.
We could disable the whole test suite, but since only one test case is
affected we can also disable only that one.
## What?
Currently we use the initial compile to add entrypoints that we know are
going to be used in the application. For example the Next.js runtime,
`react`, `react-dom`, and such. While this was the right default when
Next.js only had `pages`, it's no longer true when both `pages` and
`app` exist. E.g. when you're working on a page using App Router we'd
still compile `pages/_app`, `pages/_document`, and `pages/_error` even
though those would not be used. In case of larger applications (e.g.
Vercel's application) this would mean thousands of extra modules being
compiled even though you don't need them for the page you're looking at.
Similarly we'd compile the Next.js runtime for App Router even when
you're only using `pages`.
This PR changes the handling to only compile the entries that are needed
for the current set of visited pages (on-demand-entries). If that set
only includes `app` entrypoints then the `pages` related files will be
excluded. If the set contains both `app` and `pages` both will be
included. Similarly for `amp`, if you don't use `amp: true` / `amp:
hybrid` the development runtime will not be compiled.
📔 Note: This is specifically for webpack, Turbopack already compiles
everything needed lazily so it didn't have this limitation.
#### Before
```
- event compiled client and server successfully in 1079 ms (306 modules)
- event compiled client and server successfully in 155 ms (306 modules)
```
With opening `/`:
```
- event compiled client and server successfully in 1118 ms (306 modules)
- event compiled client and server successfully in 157 ms (306 modules)
- event compiled client and server successfully in 599 ms (486 modules)
```
Total: 1.874ms (Note: This number is much higher when `pages/_app`
imports many modules).
#### After
```
- event compiled client and server successfully in 118 ms (20 modules)
- event compiled client and server successfully in 65 ms (20 modules)
```
📔 Note: opening the page then causes the Next.js / React runtime to be
compiled ofcourse
```
- event compiled client and server successfully in 115 ms (20 modules)
- event compiled client and server successfully in 57 ms (20 modules)
- event compiled client and server successfully in 1137 ms (361 modules)
```
Total: 1.309ms (Note: This number is not affected by`pages/_app`
importing many modules).
## How?
We can only apply this optimization after we've looped over the list of
on-demand entries, as that has the required metadata. Hence why I went
with deleting the keys for each respective type of entrypoint (`pages`,
`app`, `amp`).

## Problem
Relative hash/query handling in `next/link` (e.g. `<Link
href="#hello">`) is broken in App Router, especially if you're on a
nested route.
This wasn't a problem in `/pages` because the href always get fully
resolved in `<NextLink>`; i.e. if you have `<Link href="#hash" />` on
`/hello`, it'll resolve the href to `/hello#hash` and use that
everywhere.
However, in App Router, `<Link>` no longer uses the current location to
resolve the href:
5451564f36/packages/next/src/client/link.tsx (L450-L457)
Therefore navigating with `new URL(href, location.origin)` will skip the
current path and always apply the relative hash/query to the _root_
route:
5451564f36/packages/next/src/client/components/app-router.tsx (L208-L215)
## Solution
Not 100% sure if this is the best solution, but since `app-router` is
already reading `window.location`, I'm using `location.href` as the base
URL to resolve the href.
I grep'd for `location.origin` and checked other callsites; seems like
only `app-router` deals with user specified hrefs.

https://github.com/vercel/next.js/issues/44139, and potentially

---------
This adds new `build and test` and `build and deploy` workflows in favor
of the existing massive `build, test, and deploy` workflow. Since the
new workflows will use `pull_request_target` this waits to remove the
existing workflow until the new one is tested.
While testing this new workflow flakey behavior in tests have also been
addressed. Along with the new workflow we will also be leveraging new
runners which allow us to run tests against the production binary of
`next-swc` so this avoids slight differences in tests we've seen due to
running against the dev binary.
Furthermore we will have a new flow for allowing workflow runs on PRs
from external forks which will either require a comment be checking a
box approving the run after each change or a label added by the team.
The new flow also no longer relies on `actions/cache` or similar which

Since the static metadata routes should always be static that can be
optimized, they should be marked as default runtime (or basically no
runtime). This PR change the runtime detection, if it's a static
metadata route file, its runtime will be erased.
So that it won't be picked up by `edge-app-route-loader` and then by
`next-image-loader` which emits the unexpected static file
Fixes NEXT-1238
If using Server Actions on the client layer without enabling the
`serverActions` feature, the build should error. Add a test case to
ensure #50199 works.
Since there is no longer a limitation that requires us to static analyze
`process.env`, this PR removes it from the build process and updates the
corresponding documentation.

Fix react and react-dom aliases are not properly set for `pages/`
* Remove alias react-dom internals to `{}` in edge runtime as we're using server rendering stub as alias
* Add `react$`, `react-dom$` missing aliases
* Only apply alias to builtin react/react-dom when it's app dir assets.
* Add `react|react-dom/package.json` resolving to require-hook
* Fix hmr issue that sometimes it will perform a reload when a hard navigation is triggered
Currently the edge runtime does not support static generation so this adds a warning when `force-static` is leveraged with `edge-runtime` as it will cause unexpected behavior. Support is being investigated so this isn't a hard error at the moment.
x-ref: [slack thread](https://vercel.slack.com/archives/C03S8ED1DKM/p1684783403551589)
## What?
After landing #49855 I found a few more edge cases with not-found not
behaving as expected:
- When navigating directly to a not-found page (e.g. `/testabc`) the
error boundary would not reset as there were multiple levels being
triggered at the same time.
- When running in production navigating back/forward to the not found
page caused the page to become empty
Both issues are fixed by this PR. I've added tests for both.
## How?
- Ensures `asNotFound` is not set on the layout-router, it causes all
levels to trigger not-found, even though only app-router needs it
- Ensures navigations to 404 are always a mpaNavigation (browser
navigation) instead of trying to do a client-side navigation (mirrors
what we do in `pages`)

Closes NEXT-1207
For static member expressions like `foo.bar`, we currently treat it as one whole Ident `foo.bar` and pass it over the `$$bound` array as one value. That causes a problem where the Ident inside the function body needs to be converted, because it can no longer access to `foo`.
Closes#49985.
fix NEXT-1206
## What?
@steven-tey noticed that on upstash.com that scrolling to hash keeps
happening regardless of the hash being set:
- Open site
- Click `Pricing` which adds `#pricing` and scrolls to the
`id="pricing"`
- Click `About`
- Click on the logo
You'll notice that navigating back to the homepage ends up scrolling to
the `id="pricing` instead of to the top of the page.
## How?
This happened because we didn't reset the `hashFragment` and
`segmentPaths` for scrolling when scroll was applied, which means it
would keep that value in the state and would be applied as such on
navigation.
This PR ensures that besides setting `apply` to `false` we also reset
the `hashFragment` and `segmentPaths`.
Fixes NEXT-1205

This PR fixes a warning that previous looked like the following:
```
Warning: fetch for [object Request] specified "cache: default" and "revalidate: 60", only one should be specified.
```
## What?
Currently the error boundary state does not reset when a navigation
happens because the `key` does not change. Because of that navigating
using next/link when the error boundary is in the open state ends up not
rendering the contents of the new navigation, instead it keeps the error
boundary contents.
## How?
This PR uses a pattern that is recommended in the React docs (setState
during render) to reset the error boundary if the `usePathname` value
has changed, it is used as a proxy for a new navigation.

Follow-up to https://github.com/vercel/next.js/pull/49628 this updates
the `export const fetchCache` handling and `cache: 'no-store'` handling
as discussed which also aligns with our docs here
https://nextjs.org/docs/app/api-reference/file-conventions/route-segment-config#fetchcache
- `export const fetchCache = 'force-cache'`: forces all fetches to be
cached regardless of `cache: 'no-store'` but cacheable `revalidate`
values still take priority
- `export const fetchCache = 'default-cache'`: ensures fetches are
cached even if they come after a `cache: 'no-store'` fetch but don't
override `cache: 'no-store'` itself.
- without `export const fetchCache`, we still disable fetch cache for
successive fetches after a fetch that does `cache: 'no-store'`
x-ref: [slack
thread](https://vercel.slack.com/archives/C03KAR5DCKC/p1683732826894469)
The `pathname` in app-render was actually "page" (e.g. `/blog/[slug]`),
with special url conventions. Instead we should use actual request url
as pathname. Rename previous `pathname` arg to `pagePath` for better
readability
Also improved the url validation
In Hot Reloader we use `mod.resource.replace(/\\/g, '/').includes(key)`
to see if the module is the entry. However that `includes` check isn't
solid. Say the entry key is `app/path/page`, these will all be matched:
```
app/path/page.js
app/path/page.css
app/unrelated/app/path/page/another/page.js
```
This PR fixes that and added a test case. I'm unsure if this fixes the
newly reported cases in #43396.
fix NEXT-1110
Fixes: #43598
This was a tricky one to find! Not sure why more people aren't
complaining about this issue, was super annoying in my use case since
links had the wrong URL.
## What?
This issue only occurred when basepath was defined and middleware and
dynamic pages are being used.
Example from the reproduction repo mentioned in the issue tagged:
<img width="686" alt="Screenshot 2023-04-23 at 9 32 55 PM"
src="https://user-images.githubusercontent.com/11258286/233850968-e14f6b49-858b-410e-b8f9-93c90447090a.png">
## Why?
`nextConfig` wasn't passed to `getNextPathnameInfo` function, hence the
basePath wasn't removed from a intermediate variable and that trickled
down to cause this issue.
Added test case based on the issue reproduction repo
