This PR fixes a bunch of bugs and it now supports:
- Importing a client component from a nested server component (a.server → b.server → c.client).
- The `export from` syntax in server component (`export { default } from './a.server'`)
- Native modules in server components (currently broken)

Fixes#35449
Include the shared components (from source code) is in client bundles, previously we lost them so that the client components imported by them are lost in module graph
* let flight server loader apply to all pages and imported modules (except node_modules at the moment)
* if it's a shared component from source code, include it in client bundle
* ignore handling node_modules at the moment (due to the limitation support of esm imports with RSC)

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

## 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.

Since we are applying this loader to more files, and these two simple RegExp filters will be executed ~70 times per entry, it's an easy optimization to move the RegExp creation outside and merge related testers into the RegExp.

Fixes the problem that global `process` variable has only the `env` field.
Also fixed the issue that the `env` field is empty when the `process` module is used as the value of the variable (which happens when the module is contained in a dependency of application).

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.

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#33879
The `export default xxx` statement is slightly different from estree when exporting an arrow function instead of identifier in swc.
We also need to capture arrow exports.
This fixes our parsing of params with i18n for optional catch-all routes and ensures a regression test catches this case.

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.

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.

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.
Related to #30994.

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.

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.

Closes#30654
Currently the `dev` option isn't passed to the render function inside the middleware SSR loader. This PR fixes it with a test case.
Fixes#30547.

This PR adds buffering to `renderToReadableStream` with `onCompleteShell`, to ensure that we don't flush too early and `<head>` is completed when the client receives the first chunk of data.
X-ref: #30547.
resolve absolute URLs in CSS when using urlImports
remove `[path]` from static static image output path
replace file-loader with asset module, remove file-loader
This will ensure an image hashed consistently regardless of how its imported:
- `import file from "./file.png"` -> /_next/static/media/file.12345678.png
- `url(./file.png)` -> /_next/static/media/file.12345678.png
- `new URL("./file.png", import.meta.url)` -> /_next/static/media/file.12345678.png
This PR adds support for [Middleware as per RFC ](https://github.com/vercel/next.js/discussions/29750).

Follow-up to https://github.com/vercel/next.js/pull/29307 this ensures the `blurDataURL` is correctly prefixed with the `basePath` in development since we use the `_next/image` endpoint to generate the placeholder in dev mode.

This ensures we prefix the `src` for static images with the `basePath` correctly, this also copies over the static image tests to the basePath image-component suite.

We're no longer currently planning on supporting caching for dynamic responses, so we can do some cleaning & simplification:
* Multiplexing can be removed since we only ever subscribe once (via `RenderResult.pipe`, described below)
* `RenderResult.toUnchunkedString` can become synchronous since static responses are never chunked
* `RenderResult.forEach` can become `RenderResult.pipe` which helps encapsulate some of the details of `RenderResult`
Our `Observable` use has gotten sufficiently complex that it makes sense to just use a 3rd party implementation and not worry about maintaining it ourselves. As a bonus, it doesn't rely on Node APIs.
Adds `RenderResult`, replacing the `string` that `renderToHTML` used to return, with an `Observable`-like API that callers can use to subscribe and get a callback when chunks are available to flush, etc.
This is the last architectural change needed for streaming. There are, however, other things currently standing in the way of streaming. For example, it is common to mutate `res` in `getServerSideProps` to do routing work, or write headers, before fetching page data. This pattern effectively nullifies any advantages of streaming. I may do a follow-up PR that adds an experimental alternative for applications not using React 18, but the main purpose for this support is for Suspense and Server Components.
For that reason, there's no actual streaming here yet: instead we just flush a single chunk. A follow-up PR will add support for streaming suspense boundaries in React 18.

Currently there is a lot of mutation in the Next.js Server and the checks for Locale are directly coded in the general request handler. Ideally, we should have a function where we just pass the request input (url + headers + config) and generate a bunch of metadata that analyzes it generating all metadata we might require for both the URL and i18n + basePath information.
This PR brings:
- A new parsing function `parseUrl` that joins parsing an absolute/relative URL into a data structure compatible with the Node parsing output but missing redundant properties.
- A wrapper `parseNextURL` that extends `parseUrl` analyzing `i18n` and `basePath` based on the provided configuration, url and headers. This function is pure and stateless so it can be used outside of the Next.js context.
- Types improvements and reuse.
- Refactors `next-server.ts` request handling using the above mentioned functions so that the code there just apply effects to the `req` object and the `parsedUrl.query` leaving the code much more straightforward.
- Refactors `getRouteRegex` decomposing in two different functions where `getParametrizedRoute` can be used to retrieve the serializable data that is used to generate the Regex.
This PR changes the implementation of `placeholder=blur` when using `next dev` so that it lazy loads on-demand.
This will improve the developer experience for web apps with many blurred images.
fixes#26607
This change makes it so the image loader plugin only emits a file while processing an image import for the client. The final generated image URL was already the same in SSR and CSR anyway, so this change doesn't have any functional impact.
I also changed the name of the static page in the image component tests, since it was causing some conflicts with the static assets folder.

There are strict conditions for using `placeholder=blur` documented in #25949 but this will give the user a better understanding during `next dev` and links to the error.
- Error when `placeholder=blur` and no `blurDataURL`
- The Error for small images with `placeholder=blur` has been changed to a warning
- Added support for blurring a webp image
- Added error page linking to relevant docs
This makes sure a catch-all rewrite doesn't override the params from a dynamic route in minimal mode, it also makes sure we don't attempt applying headers and rewrites un-necessarily in minimal mode.

This bumps the babel cache key since we modified the `react-loadable` babel plugin and we don't want any cached versions used since the module names generated in previous cached version won't match the newly expected values.
