### What?
### Why?
### How?
Closes NEXT-
Fixes #

closes#48416
### What?
Standardize the "Note" format in the Next.js documentation for improved
consistency and readability.
### Why?
There are currently four different variations of "Note" formatting in
the documentation.
Standardizing to a single format will improve the overall experience for
users.
### How?
Update all instances of "Note" in the documentation to follow the most
common format, `**Note**:` (used in 27 files).
This will involve updating the following variations:
- `Note` (12 files)
- `Note:` (20 files)
- `**Note:**` (21 files)

This PR corrects the file names of chunks in the flight manifest.
Previously we assume that the chunk file is always named as
`(requiredChunk.name || requiredChunk.id) + '-' + requiredChunk.hash`
and located in `static/chunks`. This isn't always true (see the comment)
especially when a chunk was generated via `import()`. Another mistake
was that we assume that one chunk only generates one file, but it's
actually possible that it depends on multiple files.
This should address many of the "Chunk failed to load" errors.
Closes [#47173](https://github.com/vercel/next.js/issues/47173), fixes
NEXT-847
fix#47173
Closes NEXT-684, closes#43396.
This PR implements a temporary workaround to address the issue that some
browsers are always caching CSS resources during the lifetime of a
session. We re-introduce the versioning query to the resource to avoid
that, and then use Mutation Observer to do GC manually on the client.
Once Float handles that by itself, we can probably remove this.
Note that correctly handling GC here is **required** for correctness,
not an optimization. That's why it took us a while to address this (even
this PR is still a temporary workaround). Imagine that if you have:
```css
h1 {
color: red;
}
```
and then you changed it to:
```css
h1 {
font-size: 300px;
}
```
During HMR, if we don't remove the old resources but only insert the new
one, both will be applied and you will still see the `<h1>` in red,
which is wrong.

### How?
Closes NEXT-

### What?
This PR changes to the `root` of the cargo workspace to the root of repo
itself, allows next-swc and other rust codebase can use repo root as
workspace root.
### Why?
Currently cargo manifest for the next-swc is not placed under the root
of the repo, which makes invocation to the tool requires to change cwd /
or set cwd. Similarly needs to open editor to the root of the cargo
manifest separately to able to utilize language server kicks in. Moving
manifest to the root consolidates those, so can invoke either cli / or
editor to the same root of the repo.
Use should only need to configure one `metadataBase` as fixed domain or
url but metadata image routes can still work properly with `VERCEL_URL`
in preview deployments
If you configured `new URL('https://mydomain.com')`, it will work for
canonical url all the time since it's for SEO.
For preview deployments metadata image routes will work with deployment
url as they're always bound with deployment.
For production deployments metadata images routes can be alias to the
configured `metadataBase` as they could be the expected exposed domain
Follow up for #47910

If `this.serverOptions.dir` is `'.'` or missing (which seems to be the
case in Vercel's `___next_launcher.cjs`), this code was calling
`require(join('.', '.next', 'server', 'instrumentation'))` which is
`require('.next/server/instrumentation')`; notably, require treats this
differently from `require('./.next/server/instrumentation')`, which is
actually what we need here.
Use `path.resolve` instead so that we pass an absolute path to
`require`, which I confirmed fixes the issue.
### What?
Currently `pushState` / `replaceState` happens in `useEffect`. This
causes a problem with timing as the history navigation will happen the
moment the new page has been rendered. In short that means that you'll
see the new route rendered before the history entry is injected. This
causes some issues:
- Scroll position for back/forward navigation (popstate) is not
preserved correctly
- Safari takes a snapshot of the current page at the point of navigation
that is then used to show when you "swipe to back" on iPhone/iPad/Mac
### How?
This PR changes the approach to `useInsertionEffect` based on the advice
from @sebmarkbage. This runs before the new page contents get committed
so it ensures the history navigation is captured before additional
rendering happens.

This PR implements next.config.js's `modularizeImports` option to
turbopack. It tries to read next.config.js, and then apply transforms as
same as `next-swc` does. Internally it interops betwen next.config.js's
PackageConfig to swc's PackageConfigs, as it doesn't have necessary
attributes for the Vcs / deserialization.

For static metadata files, we should always generate static routes
instead of generate dynamic routes, so that they won't be deployed as
serverless functions which executing file reading in deployment
We decided in https://github.com/vercel/next.js/pull/48308 that we won't
use `turbo` when packing packages for tests.
This PR removes all code associated with that effort. The whole thing
fas behind a flag, so it shouldn't affect anything.
fix NEXT-1025
### What?
The team working on vercel.com reported that multiple pages were being
compiled when opening a single page. Investigated this a bit and found
it was caused by the matching logic (that also triggers compiling of
matched pages) running before middleware runs.
### How?
Removed this matcher logic, as far as I can tell it's not actually being
used. Probably a leftover from when we provided `page` as a middleware
parameter before we made middleware run in front of all resolving.

### What?
This PR enforces turbopack uses `automatic` jsx runtime.
- closes WEB-901.
### Why?
If you set `ts|jsconfig`'s `jsx` to any custom value, you'll encounter
next.js message
```
The following mandatory changes were made to your tsconfig.json:
- jsx was set to preserve (next.js implements its own optimized jsx transform)
```
Then internally transform sets jsx to use automatic runtime instead. In
case of turbopack, its transform pass is embedded so instead of setting
it to preserve falls back to automatic by default. PR doesn't handle
validations / or emitting user friendly messages yet, just enforce
runtime config regardless of how user sets it.
There maybe some additional followups to mimic exact transform existing
next.js does.

Currently POST requests to `"use server"` entries are not correctly
handled, and this PR partially fixes the behavior. Note that the
`isMultipartAction` case is still missing as we can't simply use
`busboy`. Later we'll unify the implementation here to always use
FormData via Undici.
Fixes NEXT-1026.
We've supported `export const config = { ... }` to sepecify `runtime`
etc. configs for pages under `app/` for a while. This PR is going to
drop it and only support `export const [config name] = [config value]`
per config
Add a warning if the legacy usage is detectd
Closes NEXT-1016
### What?
This PR ensures the jest configuration is json-serializable. It also
adds a bunch of typescript types.
### Why?
Jest requires that the configuration be json-serializable. See #47407
for details on the issues caused when it isn't. However, prior to this
commit, we were passing the entire next config as a property in the swc
jest transformer options. The next config includes some fields that are
not serializable, such as some functions.
### How?
In this PR we instead pluck the fields out of the next config that we
actually need and pass only those into the swc transformer.
This PR also adds a bunch of more precise typescript types where we were
previously just using `any`. This helps confirm that the configs are
being threaded through correctly. I think this type safety is enough to
confirm this commit and adding tests would just be redundant.

### What?
Rename originUrl to fetchUrl for clarity.
Also remove remove it from origin fetch annotation because the data is
redundant.
### Why?
- The word fetch better matches the other two parameters fetchType and
fetchIdx
- Because the fetch/origin URL is the actual URL being performed on the
origin fetch, it will always be duplicate data
### What?
* fix app dir chunking
* fix app dir 404s
* improve app dir performance
* rerender shadowportal on errors to re-add nextjs-portal to avoid empty
page
* inject polyfills before user code
* fix manifest generation
see also https://github.com/vercel/turbo/pull/4488
### Why?
App dir was very slow and lead to 404 errors
### How?
add included metadata to chunks to allow deduplicate chunk loads at
runtime
### What?
In environments where `FileSystemCache` is used, the cache for static
resources such as image files will be broken.
### Why?
Because `fs.readFile(path, 'utf8')` tries to read a file as a `string`.
### How?
Change to use `fs.readFile(path)` to always read files as binary
(`Buffer`).
### What?
This PR fixes misordered CSS `<link>` tags. CSS imports in inner layers
(e.g. a page) should always take precedence over outer layers (e.g. root
layout), but currently it's reversed.
### Why?
In layouts we usually define more general styles like globals, resets,
and layout specific things. And in inner layers and pages, things need
to be more detailed and override upper layers if there're any conflicts.
Previously we defined the component segment as
```tsx
<>
<Component {...props} />
{assets}
</>
```
which is necessary because of `findDOMNode` - if we put `assets` before
the component, we can't find the correct scrolling DOM and position for
that layer.
However, with `assets` being the last Float will receive the reversed
order of resources.
### How?
I changed the `createComponentTree` function to return a `Component` and
`assets` pair, so in the Layout Router they're no longer passed to the
scroll wrapper altogether but separately.

This PR fixes parallel routes navigation with `prefetch={false}`. This
was broken because the optimistic tree created when navigating with
prefetching disabled resulted in a state where the router tree was
expecting an incorrect node to be rendered and suspended until the
imaginary data arrived.
The fix consists of updating the method that creates the optimistic tree
in order to bailout of the optimistic tree creation when there are
multiple parallel routes for the current node.

This PR fixes a bug with interception where the rewritten path passed an
incorrect segment data on production, resulting in a 404.
The fix consists of moving the rewrite pre-processing step that rewrites
the dynamic segment from the originating path to when we actually
generate the rewrite. This is needed because that step does not run on
production. Now it does and signals correctly to the app-render that the
value for the segment can be determined from the path.
Also enables prod testing, which I had forgotten to enable.
