When using standalone output in a monorepo, nextjs will sometimes throw:
`> NX ENOENT: no such file or directory, open
'/dist/apps/my-app/.next/standalone/apps/my-app/server.js'`
next.config.js:
```js
const { withNx } = require("@nrwl/next/plugins/with-nx");
const path = require("path");
/**
* @type {import('@nrwl/next/plugins/with-nx').WithNxOptions}
**/
const nextConfig = {
output: "standalone",
experimental: {
outputFileTracingRoot: path.join(__dirname, "../../"),
},
};
module.exports = withNx(nextConfig);
```

Before migrating "loadable" the from js to ts, the reload-ready function initialized its "ids" parameter with an empty array. The migration step added the parameter type but removed the initialization.
Providing an empty array as the default value for the ids parameter is necessary; otherwise, the ids variable in the createLoadableComponent function, line 102, gets undefined, and the loading of components fails.

Previously we were targeting lower versions of Node.js for `app` directory support, but a higher version of Node.js (with support for `AsyncLocalStorage`) was made required to use `undici` instead of `node-fetch`. This PR serves to:
1. Simplify the usage of those storage objects by removing the unnecessary fallback code. Everything now just uses the native `AsyncLocalStorage` interface.
2. Isolates the initialization of each store within it's own bound context to prevent leakage.
3. Adds immutibility flags to variables that should only be initlaized once upon store creation to prevent errors. This actually revealed some bugs in the implementation that were corrected.
In the event that this was in error, the following adapter could be used to simulate the previous beheviour with minor changes to the present implementation ([see this gist](https://gist.github.com/wyattjoh/6f3dffb99a4ac1a8254c90284f05026a)).

## 📖 What's in there?
With Edge Function GA for API Routes, it would make sense to suggest
developer to change their runtime key from `experimental-edge` to
`edge`.
Current behavior is:
1. when using `experimental-edge` in API route:
> prints a warning _once:_ `warn - You are using an experimental edge
runtime, the API might change.`
1. when using `experimental-edge` in pages:
> prints a warning _once:_ `warn - You are using an experimental edge
runtime, the API might change. `
1. when using `edge` in pages:
> throws an error _for each page_: `error - Page /xyz provided runtime
'edge', the edge runtime for rendering is currently experimental. Use
runtime 'experimental-edge' instead.`
This PR adjust case # 1 to indicates which API file is using
`experimental-edge` (a warning per page), and suggest to migrate:
`warn - /pages/api/xyz provided runtime 'experimental-edge'. It can be
updated to 'edge' instead.`
- [x] Integration tests added
## 🧪 How to test?
Besides running e2e tests with `NEXT_TEST_MODE=dev pnpm testheadless
--testPathPattern edge-configurable-runtime`, you can create a test app
in `examples` folder:
```jsx
// examples/edge-warnings/pages/api/edge.js
export default () => new Response('ok')
export const config = { runtime: 'experimental-edge' }
// examples/edge-warnings/pages/index.jsx
export default () => <p>hello world</p>
export const runtime = 'experimental-edge'
```
Build next.js then run with `pnpm next dev examples/edge-warnings`.
You can try adding more pages with `experimental-edge` runtime (will not
produce more warnings), adding more API with `experimental-edge` (will
produce new warnings), or change page runtime to `edge` (will produce
errors).
The initial prefetching implementation was based on the response
returning below the common layout, however when static generation was
added the RSC payload for these changed to only include the router tree
patch and the fully rendered page.
Currently the flow for prefetch is this:
- `router.prefetch`
- Fetch RSC payload
- Dispatch `ACTION_PREFETCH` with RSC payload. Note: the fetch is
intentionally not in the reducer as the fetch happens during an event or
effect, e.g. hover or `useEffect`
- Reducer handles `ACTION_PREFETCH`, creates the router tree, applies
the `subTreeData` to the cache append-only. Saves the new router tree in
the `prefetchCache` part of the reducer state.
- Then, on navigation, the `subTreeData` should be already available so
there's no additional apply. The router state is applied based on the
`prefetchCache`.
This approach is fine when the RSC payload returned never overrides the
`subTreeData` of an already existing node, however that does happen in
case of static pages because the subTreeData is for the root cache node
instead of a deeper node.
The new flow for prefetching:
- `router.prefetch`
- Fetch RSC payload
- Dispatch `ACTION_PREFETCH` with RSC payload
- Reducer handles `ACTION_PREFETCH`, creates the router tree, Saves the
new router tree and `subTreeData` in the `prefetchCache` part of the
reducer state.
- Then, on navigation, the `subTreeData` and router state are applied
based on the `prefetchCache`.

When parsing a cookie, extra `=` characters are removed, when only the
first should be removed.
e.g. with the cookie
`csrf_token_ae6261a96213c493a37ea69489ee39c8bc33a53cda7d95f84efa53146145d09c=lnQptRUO/gpU26e8ZKpGIFHKqtP54vVfR7RBiph8Uc0=`
You would expect:
key:
`csrf_token_ae6261a96213c493a37ea69489ee39c8bc33a53cda7d95f84efa53146145d09c`
value: `lnQptRUO/gpU26e8ZKpGIFHKqtP54vVfR7RBiph8Uc0=`
If you use `split`, it will remove the last `=` in value, so you get:
key:
`csrf_token_ae6261a96213c493a37ea69489ee39c8bc33a53cda7d95f84efa53146145d09c`
value: `lnQptRUO/gpU26e8ZKpGIFHKqtP54vVfR7RBiph8Uc0`
This is because `split` still removes all `=` characters, even if you
use the `limit` parameter to limit it to the first 2 elements (as in the
existing code).
Solution is to not use `split` (I've used `slice` instead)

Currently we use `this.appDir + entryName` as the key of app entries. The `appDir` part is an absolute path which contains `\` in Windows, but `entryName` is a general entry name for Webpack, like `app/page`. A quick fix is to replace all `/` in the entry name with the current system separator.
Confirmed that it fixed the problem in Windows.

The default behavior for svg is `dangerouslyAllowSVG: false` which means we won't try to optimize the image because its vector (see #34431 for more).
However, svg was incorrectly getting the `srcset` attribute assigned which would contain duplicate information like:
```
/test.svg 1x, /test.svg 2x
```
So this PR makes sure we treat svg the same as `unoptimized: true`, meaning there is no `srcset` generated. Note that this PR won't change the behavior if `loader` is defined or if `dangerouslyAllowSVG: true`.
This fixes a bug where next.config.js was configured with `images.unoptimzed: true` but the Image Optimization API was not truly disabled. Since there is no way to override the config at the component level, its safe to say the API can be disabled.
Currently, to get all the chunk files that contain a specific module in a build, we use `chunk.files`. However a module itself can be included by multiple chunks, or even chunks from different entries. Theoretically that's correct but in our architecture, we only need these chunks that are from the entry that is currently rendering.
One solution is to add a 2-level key (the entry name) to modules in flight manifest, but that introduces too much size overhead to the manifest. So instead we leverage the `__entry_css_files__` field to generate a list of all files for a specific entry, and then find the intersection set of `{CSSFilesForEntry, CSSFilesForModule}` to get the corresponding CSS files for a specific Next.js entry.
Also renamed `__entry_css__` to be more specific, and did some performance optimizations.

# Reverts vercel/next.js#43587
PR #43587 breaks the `placeholder="blur"` property on the `<Image />`
component by keeping the `blurStyles`, e.g. the blurred image, after the
image is loaded.
**This regression does _not_ introduce any breaking changes or bugs.**
---
The reason for the original PR was:
> This PR remove `React.useState()` from the `next/image` component. It
was only used in the `onError` case and it was causing Safari to become
very slow when there were many images on the same page. We were seeing
1s delay blocking the main thread when there were about 350 images on
the same page. Chrome and Firefox were not slow.
The original PR is a performance improvement for Safari on a corner
case.
Additionally, when tackling this performance improvement again, the
`blurStyle` needs to know when the the image is done loading so it can
get rid of the blur. The state is updated in `handeLoading()` and isn't
just used `onError`.
## Fixes issues
- Fixes#43829
- Fixes#43689
## To reproduce
For reference this when #43587 was pulled into Next.js
[v13.0.6-canary.3](https://github.com/vercel/next.js/blob/v13.0.6-canary.3/packages/next/client/image.tsx)
- Regress the `image.tsx` to
[v13.0.6-canary.2](https://github.com/vercel/next.js/blob/v13.0.6-canary.2/packages/next/client/image.tsx)
- Do a local build with the regressed `image.tsx` on (current canary
build)
[v13.0.8-canary.0](https://github.com/vercel/next.js/releases/tag/v13.0.8-canary.0)
- Example code, (import any image you like) make sure to use
`placeholder="blur"`
```typescript
import Image from 'next/image'
import CatImage from '../public/cat.png'
<Image
src={CatImage}
width={500}
height={500}
alt="Cat"
priority
placeholder="blur"
/>
```
- Image will still have the blur after the image is loaded
- Before and after screenshot

- empty string: match only URLs without a port
- undefined: match URLs with any port

## Bug
The `findDOMNode` will be exported from ReactDOM in esm mode, but it's
not defined for SSR since SSR is using react-dom server stub bundle
which doesn't contain any thing. So `import { findDOMNode } from
'react-dom'` will error in that case with bundling.
Since it's only being used on client, we import ReactDOM and call
`ReactDOM.findDOMNode` to avoid bundling error and adding a condition to
tree-shake it off on client

In some particular cases, while using a middleware and shallow routing
the navigation get stucks and stop refreshing the page. After futher
investigation it seems that a line of code was added that causes the
router pathname to be incorrect and then making Next believe it's the
same page that is loading.

Fixes [#43367
(comment)](https://github.com/vercel/next.js/issues/43367#issuecomment-1338617317)
This fixes the issue in which pages that are in Route Groups return
status code 500 when built with `output: "standalone"` because of the
lack of required chunks in `.next/standalone/.next/server/chunks` by
handling their `.nft.json` files properly through using their
denormalized page paths, rather than their normalized ones to resolve
those files in `copyTracedFiles`.

Previously, query parameters were not available on 404 pages because
calling the router methods would change the pathname in the browser.
This change adds support for the query to update for those pages without
updating the path to include the basePath.
This additionally narrows some Typescript types that were previous set
to `any` which highlighted some type errors that were corrected.

arrow function was trying to use arguments binding but wanted arguments
of the lambda not the nearest normal function. The narrowest change is
to convert to function expression. We could also use varargs rest syntax
since this runs in runtimes that should all support that I think. I
don't think it really matters though.

There has been [some reports ](https://github.com/vercel/next.js/issues/42514)of OOMs-related crashes with Next 13. Whilst we're fixing the memory leaks that are causing this, some of which are caused by upstream issues, this PR makes Next.js' dev server restarts if it detects that it is gonna crash soon.
You can disable this behaviour by passing `__NEXT_DISABLE_MEMORY_WATCHER=1` to the env process.
## Details
Under the hood, we're using Node's cluster API to create a child worker that will basically watch the memory usage after every request and then kill itself if it goes over 90% of the maximum heap allowance.
## Test plan
I added manually a leaking function that I called before handling a request. I then manually tested that the server re-started when we were near the limit.
```
function createMemoryLeak() {
console.log('createMemoryLeak', process.memoryUsage().heapUsed / 1024 / 1024)
for (let i = 0; i < 10; i++) {
buffer.push(new Array(1000000).fill('a'))
}
}
```

Currently `useSearchParams` bails out of static generation altogether, forcing the page to be dynamic. This behaviour is wrong. Instead it should still be statically generated, but `useSearchParams` should only run on the client.
This is achieved by throwing a "bailout to client rendering" error. If there's no suspense boundary the whole page will bailout to be rendered on the client. If there is a suspense boundary it will only bailout from that point.
~This PR also adds handling for `export const dynamic = 'force-static'` combined with `useSearchParams`. If it is enabled it will return an empty `ReadonlyURLSearchParams` and skip the bailout to client rendering. Since the `staticGenerationAsyncStorage` only is available on the server - `forceStatic` is sent to the `app-router` to enable sending an empty `URLSearchParams` to match the server response.~
https://github.com/vercel/next.js/pull/43603#discussion_r1042071542 the implementation was wrong, added skipped tests and todo comment for now.

This PR doesn't change any behavior, its just refactoring.
- renamed `webpack/loaders/next-image-loader.js` to `.ts`
- moved duplicate code into shared function `optimizeImage()`
- support `height` as optional param
- convert `extension` to `contentType`
This will reduce the bundle size and also give user proper hint to upgrade to `head.js`
* Mark `next/head` as noop in app dir
* Add warning for users to check the upgration guide to migrate it to head.js
This PR fixes two memory leaks I found debugging with @sokra.
## 1) Leak in `next-server.ts`
The first leak was caused by the fact that the `require.cache` associated to the `next-server` module was not being cleared up properly, so we leaked context from modules required in that page, like API routes.
## 2) Leak with React Fetch
When evaluating a route, we also evaluated the `react.shared-subset.development.js` module where React patches the `fetch` function. The problem is that when re-evaluating a route as part of hot reloading, we were patching over the previously patched `fetch` function.
The result of this operation meant that we were keeping a reference to the context of the previous `fetch` and thus to the previous route context, thus creating a memory leak, since we only needed the new context.
## Test plan
Checked manually the heap snapshots of a test app.

As @timneutkens pointed out [here](https://github.com/vercel/next.js/pull/43819#discussion_r1042408158), changing the key will make Flight's module cache grow indefinitely. While I've thought about updating Flight's logic to clean the cache at some point, but that's tricky to do correctly as everything is asynchronous and we have to trigger clean up from outside (Webpack).
So currently, a better way I can think of is to just give Flight a proxied object as `moduleExports`. Even if Flight is getting the same object from cache, it will always require the latest module from Webpack.

Updated version of the reverted https://github.com/vercel/next.js/pull/43511
Unhandled errors that did not occur during React rendering (those errors are caught in `getDerivedStateFromError` in the Error Overlay) should be opened in the minimized toast state instead of fullscreen. For example if they occur in event handlers or setTimeout. Errors that breaks the app, such as uncaught render errors or build errors, still opens up in fullscreen mode.
The added test make sure the errors opens up as minimized, but if there's a breaking error it should "win" and open up in fullscreen. The updated tests either throw errors inside an event handler or a setTimeout, or the error is handled in a custom error boundary - which means the app don't break.
Closes NEXT-128

### Summary
Migrate `next/dynamic` to implementation based on `React.lazy` and
`Suspense`. Then it becomes easier to migrate the existing code in pages
to layouts. Then we can support both `ssr` and `loading` option for
`next/dynamic`.
For `loading` option, it will work like `Suspense`'s `fallback` property
```js
<Suspense fallback={loading}>
<DynamicComponent />
</Suspense>
```
For `ssr` option, by default `React.lazy` supports SSR, but we'll
disable the `ssr: false` case for dynamic import in server components
since there's no client side involved.
Then we don't need `suspense` option anymore as react >= 18 is always
required. Mark it as deprecated.
It also supports to load client component dynamically in server
components now.
#### Code code changes
* switch loadable component to `lazy` + `Suspense`
* will make sure it's retuning a module from `loader()` to
`loader().then(mod => ({ default: mod.default || mod }))` since `lazy()`
only accepts loader returning a module
* Inside suspense boundary, throwing an error for ssr: false, catch the
error on server and client side and ignore it.
* Ignore options like ssr: false for server components since they're on
server, doesn't make sense
* Remove legacy dynamic related transform
#### Feature changes
* `next/dynamic` will work in the same way across the board (appDir and
pages)
* For the throwing error, will make it become a API that throws error
later in the future, so users can customize more with `Suspense`
* You can load client components now in server components with dynamic.
Resolves#43147
#### Tests
* existing dynamic tests all work
* add case: import client component and load through next/dynamic in
server components
### Issues
This is one of the required changes to refactor bundling strategy for
pages and app.

Previously we were assuming that `serverOnlyChanges` is the same as
"server component changes". However that's not always true, as one can
change a component from server component to client component, or vice
versa, where the change affects both server and client builds, so
`serverOnlyChanges` will be empty.
This PR fixes the logic by strictly hashing and comparing modules in the
server layer. Note that I intentionally skipped the test as this fix
[isn't
complete](https://vercel.slack.com/archives/C035J346QQL/p1670343453333079).

Reverts vercel/next.js#43597
The tests were disabled and currently the checking of these components
are not reliable, it also breaks the hmr. Revert it for now and then
we'll revisit how to re-enable the required tags checking
There has been a few complaints about memory usage of the Next.js 13 dev server. One of the reasons why is that prefetching is always enabled when a link is visible on app routes (and not on pages). Disabling this behaviour, whilst keeping prefetching on hover/click, should help improve resources usage.

### Update
We removed the `<head>` element checking for root layout in #41621. Since we also need `<head>` for preload in the future, and also css-in-js will require that. We're adding back the `head` element checking to make sure user always provide valid root layout including it.
### Issue
An issue was reported [here](https://github.com/mui/material-ui/issues/34905#issuecomment-1331945868) that the Emotion/MUI site was suffering from FOUC.
After an inspection, I noticed that the SSRed HTML didn't contain the inserted styles at all - despite them being inserted through `useServerInsertedHTML`. I managed to debug it down and discovered that their layout was missing `<head></head>` and thus the stream transformer skipped the insertion altogether cause of this check:
fbc98abab3/packages/next/server/node-web-streams-helper.ts (L177-L183)
I've figured that at the very least we could surface this as a console error in development to nudge the user to fix the missing `<head/>`

In #42987 we added support for `transpilePackages` in `next/jest`, but
the pattern is not functioning how we would expect here, and as a result
all modules from `node_modules` are getting transformed. File patterns
that should not be transformed should match, but due to the trailing
`/`, no packages are matching.
Currently (no match, incorrectly gets transformed):
https://regexr.com/73fvo
With this fix (matches, correctly does not get transformed):
https://regexr.com/73fvr
As far as I can tell, the `pnpm` pattern is being generated correctly.
@balazsorban44 I wasn't sure the best way to test this one, let me know
if you've got an idea. 🙏

This PR is a follow-up PR of [PR
43304](https://github.com/vercel/next.js/pull/43304).
This fix works by checking if the page is listed in
middleware-manifest.json's functions, if true then skip the
handleTraceFiles process. This also fixes the two issues aforementioned
by copying files listed in middleware-manifest.json for those pages.

This PR remove `React.useState()` from the `next/image` component. It
was only used in the `onError` case and it was causing Safari to become
very slow when there were many images on the same page. We were seeing
1s delay blocking the main thread when there were about 350 images on
the same page. Chrome and Firefox were not slow.
Related to the build failure from #41931
We need to bundle `next/head` so that it can appear in the
flight-client-manifest, so we changed the behavior to not treat it as
non externals.

This reverts a part of the changes made in [PR
43268](https://github.com/vercel/next.js/pull/43268), which is checking
whether pagesDir exists in the root/src dir before copying the output in
.next/server to .next/standalone/.next/server as this causes certain
pages to cause the script to log `Error: Cannot find module
'.next/server/pages/_document.js'` and return a `Internal Server Error`
page since Next today still depends on pages/ dir for 404 and 500 pages
and as such needs that dir in .next/standalone/.next/server.
`export const dynamic = "error"` should only throw if the page actually
didn't get exported during `next build`. Test already exist to make sure
it throws:
`test/integration/app-dynamic-error/app/dynamic-error/page.js`

Previously we stopped transform css-in-js libraries for RSC server layer because it's not encouraged to use them in server components but client components for saving the bytes of RSC payload.
We can detect styled-jsx usage on RSC server layer and error with `client-only` condition, but since it was not transformed properly so it's not erroring properly.
In the future, once styled-components and emotion have `client-only` depepdency integrated so we can re-enable the transform for them on server layer

On Windows `cunkGroup.name` is `app\layout` rather than `app/layout`. This causes it to get the wrong chunks in `flight-manifest.json` for `next/script` in this case:
```json
"chunks": ["webpack:webpack", "amp:amp"],
```
After checking for backslash:
```json
"chunks":["app\\layout:app\\layout"],
```

The server and client compilers have different external dependency resolution logic. The server prefers CJS while the client prefers ESM by default. This causes an issue when that dependency is a client component entry. We get the module reference during RSC render, which is the CJS file path. And that module reference can't be located in the flight manifest as it was generated via the client compiler (has the ESM path).
This PR changes the entry creation logic to use resolved requests, instead of the raw requests. So both SSR and client will have the same resolved import paths to ensure the module reference consistency.

fixes#39275 and related issues like #39858 and hopefully #41395 (can't
test because `pnpm next-with-deps build ./dev-app` keeps crashing on
`Collecting page data...` - `useContext` seems to be null, and even
without the changes it still crashes).
This works by checking if the file is an edge function in Next.js's
Webpack plugin `TraceEntryPointsPlugin`, if true then output the nft
file to the output path, if not move up a folder like previously. I
tried changing Webpack config's output.path from `path: !dev &&
isNodeServer ? path.join(outputPath, 'chunks') : outputPath` to `path:
!dev && (isNodeServer || isEdgeServer) ? path.join(outputPath, 'chunks')
: outputPath`, but it just causes the build script to crash because
files like middleware-manifest.json are output to outputPath/chunks
instead of the expected outputPath. So I find this to be the better
solution.

This PR improves the RSC plugin for SWC to throw an error when the `"use
client"` directive is in the top level, but not before other statements
/ expressions. For example:
Code:
```js
import 'react'
'use client'
```
Error:
```
The "use client" directive must be placed before other expressions. Move it to the top of the file to resolve this issue.

Use `WellKnownErrorsPlugin` when formatting `@next/font` errors.
The error handling is different for expected errors (like validation
errors) and unknown ones. If the error is expected it just displays the
formatted error message. If it's an unknown error it will also display
the stacktrace, and in case the versions of `@next/font` and `next` are
different it will encourage you to try to update them both.
Removes the usage of `error-loader` when importing from
`pages/_document.js`, handle that case with `WellKnownErrorsPlugin` as
well.
The current warning when using different versions is removed. If the
versions are incompatible you'll get an error in the overlay instead.

This PR is companion to https://github.com/vercel/next.js/pull/42656.
Previous PR https://github.com/vercel/next.js/pull/41908 allowed to set up integration / e2e tests spawn `next dev` with `--turbo` as needed. This PR leverages those, change all the tests suites to run with `--turbo`. One additional change is it can be configured dynamically via env variable. Setting env `__INTERNAL_NEXT_DEV_TEST_TURBO_GLOB_MATCH` to glob pattern will selectively enables tests to run with --turbo, normally it'll skip and only current devserver will be used.
These changes allow gradual integration between https://github.com/vercel/turbo to next.js. Plan is to run these tests with latest turbopack dev branch. Each time turbopack fixes / implements changes to enable certain set of tests, its CI will change its env variable without manually patching next.js's test cases. Once those change goes to upstream `next-swc` those tests can be permanantly enabled.
For those reasons, PR have somewhat verbose changes to touch individual test cases runs devserver. Changed file counts are lot, but mostly identical changes.

In #41548, I show that I would like to provide an object with images in
getStaticProps. The StaticImageData is parsed correctly and provided as
a prop to the page. Nonetheless, the image is not available in the
static directory. Therefore the image is not shown. This is also
addressed in issue #29571. The underlying cause is that the import of
the image is removed from the client bundle and only present in the
server bundle.
Evaluating the next-image-loader shows that the file is only placed in
the static directory if emitted from the client bundle by firing
this.emitFile. By changing this to only emitting the file from the
serverside bundle in the webpackloader, static images loaded in the
getStaticProps are made available properly as well as images directly
used in componts (so present in server and client bundle).
This would PR would prevent the circumventing solution which enforces
that the StaticImageData should be present in the client side bundle
while it will also be present in the staticprops.

These aliases are needed by default (removed in
b0f87fbc7c)
because when transpiling external packages specified via `file:./` in
package.json, these external packages might not have `react` in their
dependencies and the package manager might not move or link them into
the current project's node_modules. In these cases, `react` can't be
resolved unless we alias it.

After upgrading to Next.js 13, we started seeing the following HMR
errors:
```sh
$ next dev
# ...
warn - Fast Refresh had to perform a full reload. Read more: https://nextjs.org/docs/basic-features/fast-refresh#how-it-works
TypeError: Cannot read properties of null (reading 'length')
at eval (webpack-internal:///./node_modules/next/dist/client/dev/error-overlay/hot-dev-client.js:262:55)
```
This error appears related to the changes made in
https://github.com/vercel/next.js/pull/42350 (cc @alexkirsz). It appears
that `module.hot.check` will pass `null` when there are no updates:
```ts
/**
* Throws an exceptions if status() is not idle.
* Check all currently loaded modules for updates and apply updates if found.
* If no update was found, the callback is called with null.
* If autoApply is truthy the callback will be called with all modules that were disposed.
* apply() is automatically called with autoApply as options parameter.
* If autoApply is not set the callback will be called with all modules that will be disposed on apply().
* @param autoApply
*/
check(autoApply?: boolean): Promise<null|ModuleId[]>;
```
When `updatedModules` is `null`, we skip the `apply()` call as this was
producing `apply() is only allowed in ready status (state: idle)`
errors. This matches [the prior behavior when `autoApply` was
enabled](8241da7f1e/lib/hmr/HotModuleReplacement.runtime.js (L266-L272)).
Fixes#43143. Also reported on Stack Overflow:

Currently in dev the `_devPagesManifest` includes the `/app` routes as
well. However, In production, the `_buildManifest.js` does not include
the `/app` routes. This causes the `/pages` router to behave differently
in the two environments.
This change excludes the `/app` routes from `_devPagesManifest` to make
it work the same in dev/prod.

The fix in #42793 added an unnecessary step by returning a new async function when the result is a promise. We only have to make sure we don't get an unhandledRejection error if the promise rejects, React takes care of getting the data from the promise.

This ensures we properly handle prefetching with config based rewrites
with middleware configured. No additional tests have been added as the
existing tests caught this.

This adds a new `experimental.middlewarePrefetch` config with two modes
with the default being the `flexible` config.
- `strict` only prefetches when the `href` explicitly matches an SSG
route (won't prefetch for middleware rewrite usage unless manual
`href`/`as` values are used)
- `flexible` always prefetches ensuring middleware rewrite usage is
handled and also prevents executing SSR routes during prefetch to avoid
unexpected invocations

## Bug
Bumps `eslint-import-resolver-typescript` in `eslint-config-next` to the
latest version to pick up a fix from `3.1.0`. As mentioned here,
https://github.com/import-js/eslint-import-resolver-typescript/issues/107,
the typescript parser is unable to resolve the `typesVersions ` field in
their `package.json`. An example repo using this is
[`@vercel/examples-ui`](385a2e9686/packages/ui/package.json (L14-L22))
which will report an eslint `import/no-unresolved` error when using the
previous version of `eslint-import-resolver-typescript` (see
https://github.com/import-js/eslint-import-resolver-typescript/issues/107).
This was fixed in
https://github.com/import-js/eslint-import-resolver-typescript/pull/110
This can be locally fixed by bumping
`>=eslint-import-resolver-typescript@3.1.0` but decided it should be
resolved here too.

## Summary
In `appDir`, currerntly `generateStaticParams` must be an `async`
function, even if no data fetching or asynchronous operations are
involved. For example, with this
```ts
// app/[slug]/page.tsx
export async function generateStaticParams() {
return [{ slug: "Hello" }];
}
```
if I remove the `async` keyword, `next build` type checking will fail
with a rather unclear error message
```
Type error: Page "app/[slug]/page.tsx" does not match the required types of a Next.js Page.
```
However `next dev` still works fine, and after applying the type change
in this PR, `next build` and `next start` will also work fine.
Considering that `getStaticPaths` can be synchronous, this requirement
of `async` is pretty confusing. Many people have reported this type
error for not marking `generateStaticParams` as `async` (me included).
This PR lifts the restriction and allows `generateStaticParams` to be
synchronous. (If it's intentional that `generateStaticParams` must be
asynchronous, feel free to close this PR, but I don't think that
restriction is a good idea...)
Since I cannot find any test cases on the type checking process, I'm a
bit unsure in how to write a test case for this... or if a test case is
even necessary at all.

When building (`next/build/index.ts`) files ending with `page.js` got
picked up by the RegEx which meant files like `not-a-page.js` ended up
as a page. This change makes sure the segment actually starts with
`page`.
Dev had the same issue and also missed taking `pageExtensions` into
account.

This PR exposes internal injection point to specify custom binary /
bindings for the turbopack. It doesn't affect any existing native
bindings (swc), but only allows to run custom turbopack
(`turbo.startDev`) if specified.
The changes are mostly for the internal dev / testing iteration purpose.
Currently, the workflow to test new turbopack changes in next.js is
- update next-swc's cargo to point to specific changes in turbopack
- rebuild, specify next.js to use local binary
This requires additional build times (turbopack build cannot be used,
have to rebuild next-swc napi bindings) as well as if we'd like to try
some changes on the CI between next.js canary + latest turbopack,
integration gets bit tricky. 2 env variable is exposed for the purpose -
`__INTERNAL_CUSTOM_TURBOPACK_BINARY` stands for the executable binary
(next-dev) can be built in turbopack,
`__INTERNAL_CUSTOM_TURBOPACK_BINDINGS` stands for the custom napi
bindings if needed. Both are strictly internal as name implies. There
won't be any documentation, no semver guarantee or else. Current plan is
to execute some subset of next.js test on turbopack PRs with these
entrypoints.
Feature / security wise these are mostly harmless I believe - this is
devserver usually don't run on CI, and trying to print out warning if
flag is enabled.

Currently the return type is the same when you declare a variable and
when you don't.
```tsx
const inter1 = Inter()
const inter2 = Inter({ variable: "--inter-font" })
inter1.variable // string | undefined
inter2.variable // string | undefined
```
With this change you get a type error if you try to access `.variable`
without providing a variable name.
```tsx
const inter1 = Inter()
const inter2 = Inter({ variable: "--inter-font" })
inter1.variable // Property 'variable' does not exist on type 'NextFont'.ts(2339)

Cases like `next/link` and `next/router` imports are not alias since
they're not matching the existing alias pattern setting for edge
runtime, which causes router-context being bundled twice (both with cjs
and esm) into edge worker bundle.
so we resolve their paths and alias them to esm bundle for webpack
bundling.
Other minor changes:
* update `require` calls to `import` expressions in edge ssr loaders
* remove client layer for apps without `appDir` enabled
* export `type` for ts typings in next/image to avoid alias to break
resolving

* Use eager `import()` to load page/layout to avoid esm module resolution error, eager is to make sure all the sub resources like css are also included
* Fix layer detection, should use `module.layer` directly since `module.resourceResolveData` is not alway presented. It lost when switching from `require()` to `import()` for page/layout component

This PR fixes (and simplifies) CSS loader rules, major things fixed with
this PR:
- (Tests added) Even if `appDir` isn't enabled, CSS/SASS/CSSM/SASSM
should still be transpiled for packages in node_modules, configured via
`transpilePackages`.
- They should be transpiled from other packages in the same monorepo
(not inside node_modules).

The HTML `<link>` element's `onerror` function receives an Event-shaped object. The rejection here expects an `Error` shaped object. This PR 1:1 adopts the same pattern for `<link>` `onerror` that `script` `onerror` uses.

This PR adds a `--no-mangling` option to `next build` and fixes the `--profile` option so that you can use the React profiling build on production.
The advantage of disabling only mangling versus disabling minification altogether is that we still run terser and still benefit from DCE with this approach, so the `--no-mangling` does not impact performance as much.

The current `setTimeout` logic adds a constant overhead of 30ms when applying updates, which slows down HMR. As @sokra suggested, we can use the `addStatusHandler` API to have the HMR runtime let us know when its status changes. This also switches to `Promise.resolve` for update aggregation.
When under a monorepo, it's possible that the installed TypeScript isn't under `./node_modules/typescript`, and hence the `tsdk` option for VS Code won't work correctly. This PR fixes that to ensure the path is correct.

After speaking with @timneutkens, this PR provides a smoother experience to users trying to migrate over to app without affecting users in pages.
This PR adds a new export available from `next/compat/router` that exposes a `useRouter()` hook that can be used in both `app/` and `pages/`. It differs from `next/router` in that it does not throw an error when the pages router is not mounted, and instead has a return type of `NextRouter | null`. This allows developers to convert components to support running in both `app/` and `pages/` as they are transitioning over to `app/`.
A component that before looked like this:
```tsx
import { useRouter } from 'next/router';
const MyComponent = () => {
const { isReady, query } = useRouter();
// ...
};
```
Will error when converted over to `next/compat/router`, as `null` cannot be destructured. Instead, developers will be able to take advantage of new hooks:
```tsx
import { useEffect } from 'react';
import { useRouter } from 'next/compat/router';
import { useSearchParams } from 'next/navigation';
const MyComponent = () => {
const router = useRouter() // may be null or a NextRouter instance
const searchParams = useSearchParams()
useEffect(() => {
if (router && !router.isReady) {
return
}
// In `app/`, searchParams will be ready immediately with the values, in
// `pages/` it will be available after the router is ready.
const search = searchParams.get('search')
// ...
}, [router, searchParams])
// ...
}
```
This component will now work in both `pages/` and `app/`. When the component is no longer used in `pages/`, you can remove the references to the compat router:
```tsx
import { useSearchParams } from 'next/navigation';
const MyComponent = () => {
const searchParams = useSearchParams()
// As this component is only used in `app/`, the compat router can be removed.
const search = searchParams.get('search')
// ...
}
```
Note that as of Next.js 13, calling `useRouter` from `next/router` will throw an error when not mounted. This now includes an error page that can be used to assist developers.
We hope to introduce a codemod that can convert instances of your `useRouter` from `next/router` to `next/compat/router` in the future.

This changes the API of `usePathname` to return `string | null` to
support hybrid use-cases where the pathname is unknown at build time
(during automatic static optimization and when fallback is set true with
dynamic parameters in the pathname).
This supports a cleaner DX experience for those moving from `pages/` to
`app/` so they can begin to use `usePathname` in components that are
shared across them.
Improvement to how the `app` and `pages` files conflict is shown.
Especially the last log line `"pages/" - "app/"` made it seem like you
should remove the `pages` folder altogether. This was a bug in how the
`''` case was displayed. After having a look at this I went further and
added exactly which file caused the conflict given that `app` allows you
to create `app/(home)/page.js` and such it saves some digging for what
the actual conflicting file is. Similarly in `pages` both
`pages/dashboard/index.js` and `pages/dashboard.js` are possible.
Before:
```
error - Conflicting app and page files were found, please remove the conflicting files to continue:
error - "pages/another" - "app/another"
error - "pages/hello" - "app/hello"
error - "pages/" - "app/"
```
After:

Since `useRouter()` can still be used in `pages` alone and should always
be a valid instance we shouldn't change the default return type to avoid
a breaking type change.

This PR fixes the bug reported by @hanneslund (reproduction:
https://github.com/hanneslund/css-mod-import-test).
There can be multiple modules with the same resource, some of them can
be created via plugins (extracted by the mini-css plugin) and some can
be directly transformed via loaders (e.g. the CSS modules loader). In
these cases, we need to merge the resources generated by all of them.

This PR implements a configuration option in `next.config.js` to support
for rust-based MDX compiler (https://github.com/wooorm/mdxjs-rs).
Currently it is marked as experimental, as mdx-rs and loader both may
need some iteration to fix regressions.
When a new experimental flag is set (`mdxRs: true`), instead of using
`@mdx/js` loader `next/mdx` loads a new webpack loader instead.
Internally, it mostly mimics mdx/js's loader behavior, however actual
compilation will be delegated into next/swc's binding to call mdx-rs's
compiler instead.
I choose to use next-swc to expose its binding function, as mdx-rs
internally uses swc already and creating new binary can double up
bytesize (with all the complex processes of publishing new package).

Vscode `tsdk` configuration handles POSIX path even on Windows, so
there's no reason to write window-specific path to the configuration.
I've always had forward slash path in `tsdk` and work on windows and in
WSL, and that works.
f71e467143/.vscode/settings.json (L3)
Current solution will give a diff for people who have ran previous
versions on windows. We could update the check to allow windows if you
want to.
When `useSelectedLayoutSegment` is used on the current level or in a
page it should return null.

This adapts the new client hooks of `usePathname`, `useSearchParams`,
and `useRouter` to work within the `pages/` directory to aid users
attempting to migrate shared components over to the `app/` directory.
> **Exception:**
> When the pages router is not ready, `useSearchParams` will return an
empty `URLSearchParams`. This mirrors the behavior seen in the `pages/`
directory today in that `router.query` is not available until the client
hydrates.
This also adds a new option for `useRouter` to bring it line with the
correct typings with the app directory. By default, calling
`useRouter()` will return the type `NextRouter | null` to represent what
you get when you call it from a component originating from the app
directory. If you want to instead force it to return `NextRouter` as it
does today, you can pass a boolean into the `useRouter` call as such:
```ts
const router = useRouter() // typeof router === NextRouter | null
const router = useRouter(true) // typeof router === NextRouter
```
This change is designed to ease the incremental adoption of app.
This ensures we don't have a fatal error when not necessary and ensures
`@vercel/og` is working as expected.

As per
https://github.com/vercel/next.js/issues/41951#issuecomment-1294199692,
this PR improves the TS plugin error message when a non-literal
configuration is used:

Also a bug is fixed so string template literals (``const revalidate =
`auto`;``) will no longer result in an error.

In `server/render.tsx` we're switching between `react-dom/server.browser` and `react-dom/server` based on the react version users're using, unlike directly resolving them with nodejs on server side, turbopack needs to resolve both while bundling.
Removing the `hasReactRoot` condition and `__NEXT_REACT_ROOT` env var since next 13 requires latest react 18 to be installed, all the react 17 (non concurrent mode) compatible code can be dropped now.
Previously we use `path.join(compiler.context, chunk.name)` as the entry
name, which isn't always the case especially when there is the `src`
folder. This PR fixes that by using `appDir`.

fixes https://github.com/vercel/next.js/issues/42006
this issue occurred because images with `data url` src start with `blob`
and `data` will be mark as `unoptimized`, then its `sizes` will be
assigned with `undefined`.
I just skip the check for `data url` images, if there is any better
solution, we can have a discuss here.

This PR temporarily fixes#41884 by loosing the type check rules. I will
work on a follow up PR to type params better with tests.

We currently only fallback to the global `runtime` option if the page
actually **needs** a runtime (not statically optimizable). That happens
for SSG (ISR) and SSR for pages/. But for app/, we will always need a
`runtime` to render server components.
Also in this PR, I improved the tests to actually **test** the runtime
to ensure it has `globalThis.EdgeRuntime` so it's not running in the
Node.js runtime
([ref](https://edge-runtime.vercel.app/features/available-apis#addressing-the-runtime)).
