Client components might result in a page chunk or a standalone splitted chunk marked in flight manifest, this PR filters out the page chunk for standalone chunk so that while loading a client chunk (like for `next/link`) it won't load the page chunk to break the hydration. `chunk.ids` is not enough for getting required chunks, so we get the chunks from chunk group then filter the required ones.
tests: Re-enable few previous rsc tests
chore: refactor few webpack api usage

x-ref: #31506
This PR migrates existing SSR on edge from middleware to edge functions implmentation. So that we can get rid of limitation of middleware and resolve the conflicts between middleware and edge SSR routes.
* Adding edge functions matching route in middleware catch all route,keep the order as `middleware catch all` -> redirects/rewrites -> `edge catch all` -> others
* Dropping middleware related code for edge SSR: removing client info and preflight request handling
In Middlewares, dynamic code execution is not allowed. Currently, we warn if eval / new Function are invoked in dev but don't warn another dynamic code execution in WebAssembly.
This PR adds warnings for `WebAssembly.compile` and `WebAssembly.instantiate` with a buffer parameter (note that `WebAssembly.instantiate` with a **module** parameter is legit) invocations. Note that other methods that compile WASM dynamically such as `WebAssembly.compileStreaming` are not exposed to users so we don't need to cover them.

* Ensure custom middleware matcher is used correctly in client manifest
* lint-fix
* patch e2e case
* fix rsc case
* update test
* add missing normalize
* Re-introduce Edge API Endpoints
This reverts commit 210fa39961, and
re-introduces Edge API endpoints as a possible runtime selection in API
endpoints.
This is done by exporting a `config` object:
```ts
export config = { runtime: 'edge' }
```
Note: `'edge'` will probably change into `'experimental-edge'` to show
that this is experimental and the API might change in the future.
* Support `experimental-edge`, but allow `edge` too

This ensures we use the correct dynamic route params favoring params from the URL/matched-path over route-matches. This also ensures we properly cache `_next/data` requests client side when the page is not a `getServerSideProps` page.

## Bug
fixes#37106
Please note that, as for `pages/` the `src/middleware` file is ignored when `/middleware` is present.
## How to test
1. Rebuild next.js `pnpm build`
2. Run dedicated tests: `pnpm testheadless --testPathPattern middleware-src/`
It would be nice to have this attribute to compare runs with and without the `swcMinify` options.

Another strategy to do achieve the goal of #36995. With this PR the module IDs will be:
- (1) RSC: named (_this one doesn't matter_)
- (2) SSR: named
- (3) Client: deterministic
And we include the client module IDs in the flight manifest, as well as an extra mapping of 3) → 2) so during SSR it can require the correct module still.

Follow-up PR for #37134, this PR adds back the hash in each chunk's filename. This `chunks` in the flight manifest will now be `chunkId:chunkFilename` with this PR, and `globalThis.__next_chunk_load__` then handles the chunk registration (uses chunkId) and chunk loading (uses chunkFilename). (Q: how can we port this to React?)
We can't use `[contenthash]` but only `[chunkhash]` because at the stage of generating the flight manifest, the content isn't finalized and the hash changes after that.

We added custom _app as server component support in #33149, but we found it's pretty confusing on usage like support it both server component pages and regular pages at the same time for having similar layout purpose.
When using the _app.server and _app at the same time, applying them into proper places become more confusing.
In that case, we decide to make _app.js can't be a server component, and you can still keep all the existing thing there. And also you don't need to think of the corresponding APIs of custom _app in RSC

_Hello Next.js team! First PR here, I hope I've followed the right practices._
### What's in there?
It has been decided to only support the following uses cases in Next.js' middleware:
- rewrite the URL (`x-middleware-rewrite` response header)
- redirect to another URL (`Location` response header)
- pass on to the next piece in the request pipeline (`x-middleware-next` response header)
1. during development, a warning on console tells developers when they are returning a response (either with `Response` or `NextResponse`).
2. at build time, this warning becomes an error.
3. at run time, returning a response body will trigger a 500 HTTP error with a JSON payload containing the detailed error.
All returned/thrown errors contain a link to the documentation.
This is a breaking feature compared to the _beta_ middleware implementation, and also removes `NextResponse.json()` which makes no sense any more.
### How to try it?
- runtime behavior: `HEADLESS=true yarn jest test/integration/middleware/core`
- build behavior : `yarn jest test/integration/middleware/build-errors`
- development behavior: `HEADLESS=true yarn jest test/development/middleware-warnings`
### Notes to reviewers
The limitation happens in next's web adapter. ~The initial implementation was to check `response.body` existence, but it turns out [`Response.redirect()`](https://github.com/vercel/next.js/blob/canary/packages/next/server/web/spec-compliant/response.ts#L42-L53) may set the response body (https://github.com/vercel/next.js/pull/31886). Hence why the proposed implementation specifically looks at response headers.~
`Response.redirect()` and `NextResponse.redirect()` do not need to include the final location in their body: it is handled by next server https://github.com/vercel/next.js/blob/canary/packages/next/server/next-server.ts#L1142
Because this is a breaking change, I had to adjust several tests cases, previously returning JSON/stream/text bodies. When relevant, these middlewares are returning data using response headers.
About DevEx: relying on AST analysis to detect forbidden use cases is not as good as running the code.
Such cases are easy to detect:
```js
new Response('a text value')
new Response(JSON.stringify({ /* whatever */ })
```
But these are false-positive cases:
```js
function returnNull() { return null }
new Response(returnNull())
function doesNothing() {}
new Response(doesNothing())
```
However, I see no good reasons to let users ship middleware such as the one above, hence why the build will fail, even if _technically speaking_, they are not setting the response body.

This PR deprecates declaring a middleware under `pages` in favour of the project root naming it after `middleware` instead of `_middleware`. This is in the context of having a simpler execution model for middleware and also ships some refactor work. There is a ton of a code to be simplified after this deprecation but I think it is best to do it progressively.
With this PR, when in development, we will **fail** whenever we find a nested middleware but we do **not** include it in the compiler so if the project is using it, it will no longer work. For production we will **fail** too so it will not be possible to build and deploy a deprecated middleware. The error points to a page that should also be reviewed as part of **documentation**.
Aside from the deprecation, this migrates all middleware tests to work with a single middleware. It also splits tests into multiple folders to make them easier to isolate and work with. Finally it ships some small code refactor and simplifications.
## What's in there?
Partially fixes https://github.com/vercel/edge-functions/issues/82
Relates to #36715
Our webpack plugin for middleware leverages static analysis to detect Dyanamic code evaluation in user `_middleware.js` file (and depedencies). Since edge function runtime do not allow them, the build is aborted.
The use of `Function.bind` is considered invalid, while it is legit. A customer using `@aws-sdk/client-s3` reported it.
This PR fixes it.
Please note that this check is too strict: some dynamic code may be in the bundle (despite treeshaking), but may never be used (because of code branches). Since this point is under discussion, this PR adds tests covering some false positives (`@apollo/react-hook`, `qs` and `has`), but does not change the behavior (consider them as errors).
## Notes to reviewer
I looked for test facilities allowing to download the required 3rd party modules. `createNext()` in production context made my day, but showed two issues:
- `cliOutput` is not cleaned in between tests. While clearance during `stop()` would be annoying, I hope that clearance during `start()` is better.
- if `start()` fails while building, the created instance can never be stopped. This is because we don't clear `childProcess` after `build`.

Implements the first part of #33227
- Applies browserslist to JS transforms when `experimental.browsersListForSwc` is enabled.
- You don't have to use browserslist, there's also `legacyBrowsers: false` which will be the new default in Next.js 13. See #33227 for which browsers and why. `legacyBrowsers` requires `browsersListForSwc: true` to function until it is the default.
```js
module.exports = {
experimental: {
legacyBrowsers: false,
browsersListForSwc: true,
}
}
```
I only implemented the JS part of the RFC, the CSS part should be handled in a follow-up PR.

This PR brings some significant refactoring in preparation for upcoming middleware changes. Each commit can be reviewed independently, here is a summary of what each one does and the reasoning behind it:
- [Move pagesDir to next-dev-server](f2fe154c00) simply moves the `pagesDir` property to the dev server which is the only place where it is needed. Having it for every server is misleading.
- [Move (de)normalize page path utils to a file page-path-utils.ts](27cedf0871) Moves the functions to normalize and denormalize page paths to a single file that is intended to hold every utility function that transforms page paths. Since those are complementary it makes sense to have them together. I also added explanatory comments on why they are not idempotent and examples for input -> output that I find very useful.
- [Extract removePagePathTail](6b121332aa) This extracts a function to remove the tail on a page path (absolute or relative). I'm sure there will be other contexts where we can use it.
- [Extract getPagePaths and refactor findPageFile](cf2c7b842e) This extracts a function `getPagePaths` that is used to generate an array of paths to inspect when looking for a page file from `findPageFile`. Then it refactors such function to use it parallelizing lookups. This will allow us to print every path we look at when looking for a file which can be useful for debugging. It also adds a `flatten` helper.
- [Refactor onDemandEntryHandler](4be685c37e) I've found this one quite difficult to understand so it is refactored to use some of the previously mentioned functions and make it easier to read.
- [Extract absolutePagePath util](3bc0783474) Extracts yet another util from the `next-dev-server` that transforms an absolute path into a page name. Of course it adds comments, parameters and examples.
- [Refactor MiddlewarePlugin](c595a2cc62) This is the most significant change. The logic here was very hard to understand so it is totally redistributed with comments. This also removes a global variable `ssrEntries` that was deprecated in favour of module metadata added to Webpack from loaders keeping less dependencies. It also adds types and makes a clear distinction between phases where we statically analyze the code, find metadata and generate the manifest file cc @shuding @huozhi
EDIT:
- [Split page path utils](158fb002d0) After seeing one of the utils was being used by the client while it was defined originally in the server, with this PR we are splitting the util into multiple files and moving it to `shared/lib` in order to make explicit that those can be also imported from client.
This PR makes the `Options` type of base server configurable as well as assigning to `this.serverOptions`, so the web server can access it during `constructor()`. This gets rid of the dirty `__server_context` hack.

This continues off of the change in https://github.com/vercel/next.js/pull/36368 and ensures a fallback rewrite does not influence the `asPath` as these are only matched when a filesystem or dynamic route aren't matched.

We are currently using `!!ComponentMod.__next_rsc__` as the hint for the renderer to tell if the component is a server component, however that export field (`__next_rsc__`) is assigned to client components (`.client.[ext]`) as well.
This PR adds a new `__next_rsc_server__` field which is only true when the component is a server component so the renderer can handle client components correctly.

Simplify the esmodule detection. If there's any import/exprt usage, it will return `Module` in ast.type otherwise `Script` when `isModule` is set to `"unknown"`
We need to handle cjs cases for client/server components when they're compiled to commonjs in some cases.
e.g. if there's an internal `_app.server.js` in nextjs, the assets in the dist files are compiled to cjs by swc. Or any 3rd party libraries are consumed could be cjs only.
### How it works
* Detect the source file is ESM or CJS first by detect if there's any ESM import/export
* Append the new exports or collect exports info based on the module type
.substr() is deprecated so we replace it with .slice() which works similarily but isn't deprecated

Currently we ignore any files that are traced and handled by a webpack loader to prevent including webpack specific files although users may attempt reading files directly using `fs` even if they are handled by webpack so this leverages the new reason types in `@vercel/nft` to only ignore if it is solely imported.

## Summary
This PR adds a new `worker` strategy to the `<Script />` component that automatically relocates and executes the script in a web worker.
```jsx
<Script
strategy="worker"
...
/>
```
[Partytown](https://partytown.builder.io/) is used under the hood to provide this functionality.
## Behavior
- This will land as an experimental feature and will only work behind an opt-in flag in `next.config.js`:
```js
experimental: {
nextScriptWorkers: true
}
```
- This setup use a similar approach to how ESLint and Typescript is used in Next.js by showing an error to the user to install the dependency locally themselves if they've enabled the experimental `nextScriptWorkers` flag.

- For Partytown to work, a number of static files must be served directly from the site (see [docs](https://partytown.builder.io/copy-library-files)). In this PR, these files are automatically copied to a `~partytown` directory in `.next/static` during `next build` and `next dev` if the `nextScriptWorkers` flag is set to true.

Partially implements #31317 and #31506. There're also some trade-offs made with this PR: since we can't know if a certain runtime will be used or not beforehand, we have to start both runtime compilers (Node.js and Edge) and then generate entrypoints correspondingly.
Note that with this PR, the global runtime is still required to use the per-page runtime.

This PR removes the experimental `optimizeImages` flag. This feature was designed to automatically add preload tags for images, but I was never able to get it to do a very good job of selecting the images that actually need preloading.
This feature never graduated from experimental and in fact we never even publicized it as an experimental feature for people to try.
Additionally, even if someone was using this feature, it wouldn't have a functional effect, only a performance effect (removal of some preloads).
For those reasons, I believe it is safe to remove this functionality and that it is not a breaking change.
### Changes
* node server and webpack should share the same logic: auto detect react 18 and enable `reactRoot`
* fallback `_error` should use functional document if concurrent rendering is enabled
### Test
* Remove the hard code `reactRoot: true` in test suite
* Test some react-18 test suite with nodejs runtime
Related to #34185, this PR reduces the size of chunk that contains web-server.ts from 1.14mb to 210.8kb, by splitting base-http and api-utils into different environments.
Only affected thing is we can't have SSG preview mode for the web runtime via `getStaticProps`.

This PR ensures that the test "should render 500 error correctly" doesn't break when `runtime` is set to `nodejs` with `serverComponents` enabled.
This test case is now moved to the "basic" suite to ensure it doesn't break in both runtimes. And "should not bundle external imports into client builds for RSC" is enabled for the `nodejs` runtime too.

I took a naive approach and simply added `.env` to the files that need to be copied.
Do we want to include `.env.production` as well? Ref: https://nextjs.org/docs/basic-features/environment-variables#loading-environment-variables
(I haven't tested what happens if the file does not exist on copy.)
Other files like `.env.*local` or `.env.{test,development}` don't make sense to copy.

As per React 18 recommendation, we should use e.g. `renderToReadableStream` whenever we use `createRoot`. This is particularly important for currently supported suspense features like `React.lazy` to work properly during SSR.
However, unless you have opted in to streaming support (via [the `runtime` flag](https://github.com/vercel/next.js/pull/34068)), we will wait until `onCompleteAll` before sending it (via the `generateStaticHTML` flag).

Fixes: https://github.com/vercel/next.js/issues/30631
Cleans up the code of the middleware SSR loader and the web server. Currently the page components and render options are provided to the server via `globalThis` which is not ideal.
Instead we can inject `extendRenderOpts` and `loadComponent` to the web server. Since this is the the minimal mode and we'll need to handle `?flight` requests, we update the server render opts upon `updateRenderOpts` (In the future this should be changed to be passed to `requestHandler` to avoid race conditions).
Currently, we can't fully get rid of the `__server_context` global as we call `getBuildId` in the base server constructor.

(#31506 for context)
This PR implements the minimum viable web server on top of the Next.js base server, and integrates it into our middleware (edge) SSR runtime to handle all the requests.
This also addresses problems like missing dynamic routes support in our current handler.
Note that this is the initial implementation with the assumption that the web server is running under minimal mode. Also later we can refactor the `__server_context` environment to properly passing the context via the constructor or methods.
Part of #31506, this PR removes `loadEnvConfig` and `chalk` from the base server while keeping the same behavior for the node server.

Production middlewares will only expose env vars that are statically analyzable, as mentioned here: https://nextjs.org/docs/api-reference/next/server#how-do-i-access-environment-variables
This creates some incompatibility with `next dev` and `next start`, where all `process.env` data is shared and can lead to unexpected behavior in runtime.
This PR fixes it by limiting the data in `process.env` with the inferred env vars from the code usage. I believe the test speaks for itself 🕺

After discussing with @sokra, seems that the proposed solution is split in two:
* We need to make sure that the `process` polyfill uses `global.process` if available. This is because middlewares are bundled using `browser` target and therefore `process.env.MY_ENV` gets shimmed into `require('process').env.MY_ENV`.
* Allow `process.env` to be statically analyzed for dependencies so they will be exported to the manifest.

* should fix#33043.

* Move resolve-url-loader into Next.js
Fixes#32157
Moves resolve-url-loader into Next.js and strips out all features that are not used like `rework` support. Will reduce install size as well as allow for optimizing the approach in the near future.
* Update precompiled
* Use loader-utils 2
* Update trace test
* Revert "Update trace test"
This reverts commit 7c09a07871cc0ab72d5fcd4151a2d8efbc1aad8f.
* Add es5-ext as it's used in trace tests
* Update join-function.js
* Update bundle5.js
* Don't render `next/head` in _error for RSC
* Save an error in `__next_s` for client to be aware RSC rendering is errored
* Fix `req.url` when errored
* Refactor some changes in middleware ssr loader
Currently we are using a TransformStream to process the forwarded stream for the inlined data, but unfortunately the `pipeTo` method is not implemented in the web runtime. This PR changes it to a naive way of doing so.

# Description
The redirect responses do not contain a message body. This is in conflict with the RFCs (below) and causes Traefik (a reverse proxy) to invalidate the responses. In this pull request, I add a response body to the redirect responses.
This PR is similar to https://github.com/vercel/next.js/pull/25257, it appears that there are some other locations where redirection is handled incorrectly in next.js.

This PR implements the basic inline embedded server response data (#30994) for RSC, as well as partial hydration (#31338) for RSC and React 18 SSR streaming.
For #30994, `renderTargetSuffix` is passed to the `bodyResult` resolver so the stream can inject corresponding hydration scripts and the closing body tag at the correct time. The expected behavior should be _prefix_, _body shell_, _suffix scripts_, _stream and inlined data_, _close body_.
For #31338, we have to force turn on `disableOptimizedLoading` when `concurrentFeatures` is enabled to opt-out of deferred script tags.

Since #31939 is going to move the `Document` components, we can't rely on `DefinePlugin` to provide environment variables. This PR passes them as render opts instead. We can't just force this to be bundled like e.g. `next/dynamic`, because we use it internally.
`isAutoExport` should be `false` when `concurrentFeatures` is enabled.

To run middleware we are using a **sandbox** that emulates the web runtime and keeps a module cache. This cache is shared for all of the modules that we run using the sandbox while there are some module-level APIs that must be scoped depending on the module we are running.
One example of this is `fetch` where we want to always inject a special header that indicate the module that is performing the fetch and use it to avoid getting into infinite loops for middleware. For those cases the cached implementation will be the first one that instantiates the module and therefore we can actually get into infinite loops. This is the reason why #31800 is failing.
With this PR we refactor the sandbox so that the module cache is scoped per module name. This means that one execution of a middleware will preserve its cache only for that module so that each execution will still have its own `fetch` implementation, fixing this issue. Also, with this refactor the code is more clear and we also provide an option to avoid using the cache.

Initial step to refactor the rendering logic by decoupling the handler and renderer:
1. Delegate Flight rendering to server/render
2. Reuse the piper glue code for both Fizz and Flight streams
3. Add buffering for ReadableStream
In 1), this PR also makes sure that gSSP/gSP are correctly executed before the Flight stream and `pageProps` and `router` are correctly delivered to the component.

1. Align `renderToReadableStream` with `renderToNodeStream`, resolve promise of `NodeWritablePiper` only when `onCompleteShell` is called.
2. update webpack to disable chunk loading for web runtime
Item 1 is the preparation for middleware-ssr-loader. Then we can do the following there
```js
try {
result = await renderToHTML(page)
} catch (e) {
result = await renderToHTML(errorPage)
}
result.pipe(renderResult)

Fixes#30897
This PR fixes the linked issue where rewrites are not being applied for locale. It adds the corresponding test but also, as it was added in debugging process, it introduces a helper to read/write into the `request` object.
We are currently writing directly into the request by casting to `any` and then using flags like `_nextRewrote`. Instead, this PR puts all of this metadata under a symbol so it is not directly accessible. This also allows to have a single place where all of this metadata is listed so we can add comments describing the purpose of each flag.
In the same way, there is metadata written in the querystring. This is adding some types for it in order to throw some visibility on where is this metadata accessed. In an upcoming PR we can move all of it to the `request` object if possible to simplify the system.

When using the web runtime with SSR streaming, this PR significantly improves the build speed for large applications when there're large modules shared by most pages.
With another optimization, `react-dom` will now be excluded in the web runtime build if it's imported in the application. It will only take effect in the client bundle.

This fix the custom 404 is not rendering properly and can’t be built in web runtime when `concurrentFeatures` is enabled. We force 404 page to be rendered outside of middleware ssr. Then it could be the real fallback 404 page in next-server when any routes is not macthed.
Will check 500 related after #31057 is landed.

This PR improves error handling in the SSR middleware. Previously the response was sent out synchronously, and and errors were silently swallowed. There was no `.catch` for `renderToHTML`. This changes the middleware to be asynchronous, which waits until the initial Document to be rendered correctly and then starts the streaming.
With this change we can also send correct status code when there're immediate errors before Fizz.

With this PR we are updating the way we check the usage of `eval` and other dynamic code evaluation (like `new Function`) for middleware. Now instead of simply showing a warning it will behave differently depending on if we are building or in development.
- Development: we replace the dynamic code with a wrapper so that we print a warning only when the code is used. We don't fail in this scenario as it is possible that once the application is built the code that uses `eval` is left out.
- Build: we detect with tree shaking if the code that will be bundled into the middleware includes any dynamic code and in such scenario we make the build fail as don't want to allow it for the production environment.
