* For sitemap if they're not using dynamic routes generation `generateSitemaps`, should optimize them as static sitemap
* For icons and social images, if they're not using `generateImageMetadata`, should optimize them as static path
Closes NEXT-1071
Fixes#48991
The `WebSocket` constructor exposed by `undici` is not working against some db connections.
That can be considered kind of expected since `undici` docs is saying it's experimental.
We're working into isolate the issue and report at `undici` repository, but for now, let's just use `ws` for all the node versions.
This PR:
* Adds more config keys that should be supported or can be ignored
* Cleans up supported key checking and allows nested keys that aren't experimental
* Removes logging for "only supported options" since the list is much longer now
## What?
Changes the logic for running node-file-trace to no longer rely on
parsing the webpack request. Instead using the module metadata set in
each loader to generate the path.
## How?
The `route` metadata is already provided on all entry loaders since I
added `preferredRegion` support, this can now leverage `route` as well
to generate the required path.

This PR mimics fallback google font behavior for the turbopack from https://github.com/vercel/next.js/pull/47428, replaces fallback to capsize and adjust read logics.
This PR renames `experimental.experimentalReact` as
`experimental.serverActions` and makes it a hard compilation error if
it's not set but detected server actions.
### What?
This PR fixes middleware's edge-chunks not being copied in copyTracedFiles.
### How?
Merging its files' handling with other pages' ones.
### Note
I also want to exclude `process.turbopack` from the unsupported APIs list by checking if `key === 'turbopack'` in `createProcessPolyfill` and `warnForUnsupportedProcessApi`, but I want to have some opinion on this first as I don't know if `process.turbopack` works with the Edge runtime.

This fixes `next-types-plugin` causing Typescript to complain about CommonJS files importing ESM ones when `"type": "module"` is set but `experimental.typedRoutes` is not enabled.
### How?
Always create a `.next/types/package.json` with `"type": "module"` instead of only doing so when `experimental.typedRoutes` is enabled.

The issue seems to be introduced with recent React Float change, which isn't a real problem but a behavior change. Resources are layered by the `precedence` key and the style insertion logic can be simplified as "insert the new stylesheet right after the existing stylesheet in the same layer". When multiple stylesheets are inserted in the same render pass, their new order will be flipped.
This is a nice feature so we can always maintain the order of resources that might conflict.
When we enable `webpackBuildWorker` this module level `const apiRouteWarnings = new LRUCache({ max: 250 })` will be created in 3 workers, so users will see 4 outputs (last one is static optimization):

This PR fixes that and now there's only 1.
### What?
Whenever you navigated and a page suspended through `loading` or an error happened caught by `error` in the first level of segments (e.g. `/dashboard` but not `/dashboard/settings`) scroll would not be applied. This happened because the focus and scroll handling component is rendered as part of `InnerLayoutRouter` and the Suspense / Error boundary was rendered **around** `InnerLayoutRouter`. This behavior is incorrect as we still want to immediately scroll to the place where the loading is rendered.
This PR fixes the behavior by allowing the scroll to apply to loading / error too.
### How?
Moved the scrolling component around the loading/error/innerlayout boundary and added tests.
### What?
add a test case
### Why?
Some packages expect the default export of a commonjs module to be the whole exports object when importing from ESM.

We bind to an IPv6 unspecified address (`::`), which makes the old message say "started server on :::3000", and that's kinda ugly. The new message will say "[::]:3000".
This PR updates the way we preload fonts. Previously we tracked which
fonts we needed to preload for each layer and rendered a `<link
rel="preload" href="..." as="font" />` tag for each preloadable font.
This unfortunately gets blocked by data fetching and we want to be able
to hint these preloads as soon as possible. Now that React support Float
methods in RSC we can use `ReactDOM.preload(..., { as: "font" })` to
implement this functionality
This PR makes the following changes
1. expose a `preloadFont` method through the RSC graph
2. expose a `preconnect` metho through the RSC graph
3. refactor the preloads generation to use `preloadFont` instead of
rendering a preload link
4. If there are no fonts to preload but fonts are being used in CSS then
a `preconnect` asset origin is called instead of rendering a preconnect
link
5. instead of emitting a data attribute per font preload indicating
whether the project is using size-adjust we now emit a single global
meta tag. In the future we may get more granular about which fonts are
being size adjusted. In the meantime the current hueristic is to add
`-s` to the filename so it can still be inferred.
In the process of completing this work I discovered there were some bugs
in how the preconnect logic was originally implemented. Previously it
was possible to get multiple preconnects per render. Additionally the
preconnect href was always `"/"` which is not correct if you are hosting
your fonts at a CDN. The refactor fixed both of these issues
I want to do a larger refactor of the asset loading logic in App-Render
but I'll save that for a couple weeks from now
Additionally, the serialized output of preloads now omits the word
anonymous when using crossorigin so tests were updated to reflect
`crossorigin=""`
Additionally, tests were updated to no longer look for the size-adjust
data attribute on preloads
Additionally, There is a note about leaving a `{null}` render in place
to avoid a conflict with how the router models lazy trees. I'll follow
up with a PR addressing this

### What?
Implements resolving of `runtime` and `preferredRegion` in layouts. It
will resolve from the root layout down, each layout can override
`runtime` or `preferredRegion`.
```
app
├── layout.js -> export const runtime = 'edge'
├── page.js -> Edge runtime
└── dashboard
├── page.js -> Edge runtime
└── settings
├── layout.js -> export const runtime = 'nodejs'
└── page.js -> Node.js runtime
```
Adds support for `preferredRegion`. This is similar to `export const
config = { region: ['sfo1'] }` in `pages`.
However, there is a difference. It supports `export const
preferredRegion = 'home'` and `export const preferredRegion = 'edge'`.
`home` refers to the configured default region on your deployment
platform and `edge` refers to "all regions".
### How?
I've implemented a temporary resolving in `entries.ts`.
`preferredRegion` is tracked through the entry module in webpack which
is why it's added to all the loaders that create an entry module, this
prevents having to resolve/parse again later on.

We bumped `undici` fetch which has a minimum version of 16.8.0 so we need to make sure `next` and `create-next-app` also have the same minimum version.
Since 14.x reaches End-of-Life on [2023-04-30](https://github.com/nodejs/Release), we can drop support for 14 in the next release.

### What?
In #48928 we decided to error for the missing `id` from `generateImageMetadata` and `generateSitemaps` for better dev DX. This PR also refactors the metadata image urls generation that assumbling the utils together
# What?
This PR just refines some of the typescript types around `nextJest`, specifically refining the argument `customJestConfig` and the return value.
### Why?
Before this PR, the return type of `nextJest` was inferred by typescript as `any` which is inaccurate and would require type casting for typescript to enable it to be used in a jest configuration written in typescript.
I didn't add an issue for this since it was so trivial, but I can do so if it would be helpful.
* Fix the `generateImageMetadata` for non dynamic routes and related
`param` matching (Found during development)
* Fix dynamic routes with number suffix `(\d)` (Fixes#48689)
### What?
Exposing `globalThis.crypto`, based on [Node.js' WebCrypto
API](https://nodejs.org/api/globals.html#crypto_1)
### Why?
Similar to `fetch`, `crypto` is a popular API that is currently not
available on `globalThis` in all active Node.js versions yet.
This can help library authors to create runtime-agnostic packages.
### How?
Node.js already has the WebCrypto API that can be imported, we just
expose it on `globalThis` in Node.js versions where this is not
available.

Depends on https://github.com/vercel/turbo/pull/4491
This adds support for the new `output: 'export'` configuration, and
propagates the value through to our Node.js rendering code to render.
Unfortunately, we don't support page-level configs at the moment, so we
can't set a `export const config = { dynamic: 'force-dynamic' }` and
test that the export value is being received (I've manually verified it,
though).
Fixes WEB-842
The current implementation is throwing wrongly if you set a falsy JS value (like `0` or `null`)
So right now this is fail even it's a legit implementation: `process.counter = 0`
Mostly mirrors the changed made in
https://github.com/facebook/react/pull/26632 to our SWC transform. The
implementation difference is that the AST transformer only adds a
general purpose wrapper call `createServerReference(id)` from an aliased
import, so we can easily change the underlying function in the bundler.
This change only affects the client layer (when `self.config.is_server
=== false`).
Needs to be landed after another React upgrade:
https://github.com/vercel/next.js/pull/48697.

## What
We recently added the searchParams as part of the __PAGE__ key in the

instead of startsWith.
## How
Searched for ` '__PAGE__'` in order to find the leftover cases and
changed them.

This PR implements preloading of CSS from RSC.
1. The underlying Flight protocol was extended in
https://github.com/facebook/react/pull/26502 to allow sending hints from
RSC to SSR and Client runtimes. React was updated to include these
changes.
2. We now call `ReactDOM.preload()` for each stylesheet used in a
layout/page layer
There are a few implementation details to take note of
1. we were previously using the `.browser` variant of a few React
packages. This was a holdover from when there was just browser and node
and we wanted to use the browser variant b/c we wanted the same code to
work in edge/node runtimes. React now publishes a `.edge` variant which
is like `.browser` but expects to be server only. This is necessary to
get the opt-in for `AsyncLocalStorage`.
2. Even with the above change, AsyncLocalStorage was not patched on the
global scope until after React was loaded. I moved this into a module
which is loaded first
3. The component passed to RSC's `renderToReadableStream` is not
actually part of the RSC module graph. If I tried to call
`ReactDOM.preload()` inside that function or any other function defined
inside `app-render.tsx` file it would actually see the wrong instance of
`react-dom`. I added a new export on the RSC top level export which
exposes a `preloadStyle(...)` function which just delegates to
`ReactDOM.preload(...)`. This makes the preload run in the right module
graph
~There are a couple of bugs in React that this work uncovered that I
will upstream. We may want to delay merging until they are addressed.
I'll update this comment when that is complete.~
1. ~React, during SSR, can emit a preload for a style twice in some
circumstances because late discovered stylesheets don't consider whether
a preload has already been flushed when preparing to reveal a boundary
they are within~
2. ~React, during RSC updates on the client, can preload a style that is
already in the document because it currently only looks for existing
preload links and does not consider if there is a stylesheet link with
the same href.~
~both of these issues will not break functionality, they just make the
network tab look at bit more noisy. We would expect network deduping to
prevent multiple actual loads~
The above React bugs were fixed and included now in the React update in
this PR

### What?
Mux reported they're experiencing a specific case where scroll wasn't
applied. I've found a bug when the first element in a layout or page,
the one that React will return from `findDOMNode`, is display: hidden.
At that point the rect is is `0` `0` `0` `0` and the current logic
assumes that means it's in the viewport as it's top `0`.
In order to fix this I've looked at a few ways:
- Scrolling to top when the element is not visible
- Scrolling to the parent element that is visible
- **Scrolling to the closest sibling (nextSibling) of the element that
is visible**
Eventually I landed on the third option after looking at the Mux case,
my reproduction, and the way vercel.com's pages leveraging App Router
are structured.
### How?
Used a while loop to check if the domNode is visible, if not we continue
to the next sibling until one that is visible is found. If none are
found we bail on resolving further.
While looking into this it highlighted that we should add a global
scroll handler in app-router too for the case where none of the
layout-routers apply scroll. With this fix that is less urgent though so
I've added a todo.

The prefetch method is currently an async method but there's nothing to await. It's updated out-of-band. It shouldn't return a Promise.
I also found a console.log that looked out of place.
### Why
Default font file of `@vercel/og` is not loaded, because the og package is bundled by webpack and we should external it so that `fs.readFileSync` is bundled and manged that can't be traced by nft.

### What
For dynamic routes you might have different sitemap for different params
* Unloack using `sitemap.[ext]` in your app everywhere
* Support `generateSitemaps()` to create multiple sitemaps at the same time
### How
* Change the metadata regex to allow use sitemap in every routes
* Similar approach to `generateImageMetadata`, we make `sitemap.js` under dynamic routes to a catch all routes, and it can have multiple routes

> This PR implements the MutableRequestCookies instance for cookies() based on the current async context, so we can allow setting cookies in certain places such as Server Functions and Route handlers. Note that to support Route Handlers, we need to also implement the logic of merging Response's Set-Cookie header and the cookies() mutations, hence it's not included in this PR.

This PR also adds the same support for Custom Routes.
cc @styfle.
fix NEXT-942, fix NEXT-941.
## What?
When investigating #48852 I found that when there's a `segmentPath` set
in the `focusAndScrollRef` it would compare that entire path with the
`segmentPath` of the layout-router. This logic works in cases where the
entire page is rendered but doesn't take into account cases where for
example a suspense boundary is triggered below the common layout.
Because of the order `useEffect` is run in we can already assume that if
a more specific match existed it would have scrolled there. As that is
not the case in e.g. #48852 it ended up opting out of scrolling
entirely. In order to fix that the logic needs to be different, it needs
to check if the layout-router's `segmentPath` matches, if it matches
every level then we can apply scrolling in that layout-router.
## How?
Implemented the opposite of the current logic, running `.every` on the
layout-router segmentPath instead of on the router provided segmentPath.

We were adding filling in our cleanup function after we started our server. So If we restarted while the server was starting, we would fire an empty cleanup function which would lead to the server not being cleaned up (once it starts).
The only slight issue is that it won't watch for changes while cleaning up the previous run (waiting for the server from the last run to start and finish).
fix NEXT-1052
It makes more sense to use the `FormData` from `@edge-runtime/primitives` to ensure the version and implementation are aligned, and avoid importing extra modules (as we always import the Edge Runtime).
Part of #47759 (which had been reverted twice so here we only land a part of the change), relates to NEXT-926. Thanks to #48506 we can soon switch between these two channels during runtime.
Also fixes a problem of `renderKind` (only revealed after upgrading React), it should be also based on the `match` kind.
This is currently an overhead, that we check a module's layer (`mod.buildInfo.rsc?.type === RSC_MODULE_TYPES.client`) and put all client modules in the client reference manifest, but the manifest is only used for accessing these entry modules. So here we change the util to check if it's an client entry instead.
With this change the client manifest of a test app decreased from 177 KB to 70 KB.

### What?
Mux reported that their website does not scroll to hash when clicking a search result. Found it's related to `server-patch` triggering and overriding the hashFragment. That should be preserved similarly to `apply`.
### How?
handleMutable had a default of `null` instead of using the existing value. It should use the existing value.
### What?
Update `@swc/helpers` to `v0.5.1`.
### Why?
Webpack merges `@swc/helpers@v0.4.x` and `@swc/helpers@v0.5.x`, due to `resolve.alias` config in 2f6ff0dab3/packages/next/src/build/webpack-config.ts (L1070-L1072)
To workaround it, `@swc/helpers@v0.5.1` reexports from entries just like `v0.4`.
### How?
Closes WEB-948
Fixes#48593
A change here: (#48202) 958150d

### What?
Compiles Next.js core files using the same default target as client-side
files, ensuring that `async`/`await` and such are not turned into
generators.
The client-side files are all opted into compilation during dev/build
already so if you create a browserslist config that will still apply in
the same way. This change only changes the output of the core files.
### How?
Moved the default we use in Next.js into a separate `.js` file so that
it can be imported from the taskfile-swc plugin, this way we're using
the same defaults.

Draft Mode is very similar to Preview Mode but doesn't include any
additional data.
This PR implements support for Draft Mode in `pages` and a future PR
will implement support in `app`.
fix NEXT-992
When sending a multipart form data, we currently wait until the entire update finishes before we decode it via `decodeReply`. This way is universal in both runtimes (as we don't have `decodeReplyFromBusboy` in Edge), but also not efficient.
This PR changes it to use `decodeReplyFromBusboy` in the Node runtime, which can decode the payload during streaming as well as file update support.
Same purpose as #48297, but without the React channel branching logic to
make it easier to land. Since we have #48478 reverted, we only need to
consider `pages` and `app` inside the require hook.
> This PR aims to improve the current require hook by implementing two
key changes. Firstly, it ensures that the initialization occurs at the
top of the module level for correctness. Secondly, we now set the
NEXT_PREBUNDLED_REACT environment variable at the process level to
ensure that we don't mix the two types of rendering processes and we
always resolve the correct React package.

### What?
Fix snapshots that were no longer fulfilling the original purpose after
prettier had its way.
The `.prettierignore` also had the old `target/` directory (prior to the
`Cargo.toml` move in #48198) so running `pnpm prettier-fix` formatted
files in the `target/` directory
This PR implements new cache semantics for the app router on the client.
## Context
Currently, on the App Router, every Link navigation is prefetched and
kept forever in the cache. This means that once you visit it, you will
always see the same version of the page for the duration of your
navigation.
## This PR
This PR introduces new semantics for how the App Router will cache
during navigations. Here's a TL;DR of the changes:
- all navigations (prefetched/unprefetched) are cached for a maximum of
30s from the time it was last accessed or created (in this order).
- in addition to this, the App Router will cache differently depending
on the `prefetch` prop passed to a `<Link>` component:
- `prefetch={undefined}`/default behaviour:
- the router will prefetch the full page for static pages/partially for
dynamic pages
- if accessed within 30s, it will use the cache
- after that, if accessed within 5 mins, it will re-fetch and suspend
below the nearest loading.js
- after those 5 mins, it will re-fetch the full content (with a new
loading.js boundary)
- `prefetch={false}`:
- the router will not prefetch anything
- if accessed within 30s again, it will re-use the page
- after that, it will re-fetch fully
- `prefetch={true}`
- this will prefetch the full content of your page, dynamic or static
- if accessed within 5 mins, it will re-use the page
## Follow ups
- we may add another API to control the cache TTL at the page level
- a way to opt-in for prefetch on hover even with prefetch={false}

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 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.

### 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.

### 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

### 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.

- Because the fetch/origin URL is the actual URL being performed on the

### 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.
