We should use the `hasConcurrentFeatures` as the condition to enable Fizz, instead of reactRoot, otherwise just by installing React 18 will break stuff such as CSS imports.
Currently `hasConcurrentFeatures` still needs to opt-in via the global `runtime` option. Once we fixed all the CSS bugs and add back #35245, we can flip the condition here again.

The web server is used as minimal mode, whereas public file handling, envs and compression are both handled by the upper layer (edge runtime if deployed serverlessly, or node server if self-hosted).

This PR adds a new layout mode for images called `raw`, as discussed with the core team a while back. This mode has the following characteristics:
- No wrapper `span` around the `img` element
- No sizer svg
- Almost no styles automatically added to the `img` element
- `style` parameter is allowed and is passed through to the underlying `img` element
This also adds documentation changes to describe the new component.
There are a few tradeoffs and DX decisions that may warrant discussion/revision before merging. I'll add a few comments to highlight those issues.
- Related to #18637
## 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.

This PR fixes#31517.
This PR removes the `` const documentPage = `_document${globalRuntime ? '-concurrent' : ''}` `` condition from the config resolution phrase, and only use the built-in one. And later when rendering, we can conditionally convert the default class component into a function component. This change is necessary for the switchable runtime feature (#31506).

* Fix the static streaming render result isn't the resolved streaming rendering content (resolve suspense)
* Update readable stream polyfill to fit the w3c standard
Only happened with SSR without suspense case
Similar reason to #34474, the prefix (script parts) might be flushed during the render stream causing bad HTML. Use the same tricky to delay the prefix flushing
#### Expected
```html
<div>content</div> <!-- render stream -->
<script>...</script> <!-- prefix -->
```
#### Observed
```html
<!-- prefix choked the render stream -->
<div <script>...</script> >content</div>
```

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.

* Add failing colon rewrite test
* add test fixture
* better colon rewrite tests
* middleware rewrite colon tests with query parameters
* fix#31523
this addresses the symptom but the real systemic issue is that prepareDestination is called on rewrite/redirect URLs, which have no defined special behavior for colons and they should not be compiled at all
* hack around prepareDestination to skip compiling x-middleware-rewrite
this is a bit nicer than just escaping colons, but ideally we find a way to obviate prepareDestination
* obviate prepareDestination for x-middleware-rewrite handling
* don't clobber rewrite query data
* omit redundant type
* catch up to main
* It looks like newUrl should contain only pathname

Implements https://github.com/vercel/next.js/issues/30997 with some minor tweaks to the design:
* The hook is moved to Client Components (e.g. `pages/_app` instead of `pages/_document`). This was a silly oversight in the original design: the hook needs to be called during server prerendering.
* `useFlushEffects` instead of `useFlushEffect` as there isn't a particularly safe way to implement the singular semantics as a Client Component hook given the current implementation of server rendering.

Fixes#30997
Currently if you have a Next config like the following:
```js
module.exports = {
experimental: {},
},
```
You are presented with the warning for experimental features, even though you haven't actually enabled any experiments. This PR checks there's at least one key in the `experimental` object before logging the warning.
The shared utils file included an import from `react` (because it was using `createContext`) which seems to be unnecessary in the Middleware bundle.
With this PR and steps #34425 laid out, the bundle size did decrease without breaking functionality.

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
* Adding steps to build the app with docker in existing projects (without the need to create the app with the with-docker example)
* Update examples/with-docker/README.md

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).

Since we're always using `ReadableStream`, we should just get rid of `ResultPiper`.
This also lets us replace things like `bufferedReadFromReadableStream` with a `TransformStream` that does the same thing, so that it's `TransformStream`s all the way down.
Finally, we can get rid of the one-off call to `renderToReadableStream` and just use `renderToStream` whenever we're rendering a concurrent tree.
Instead of branching rendering based on Node.js and browser/web runtimes, we should just use the web version for now, which can run as-is on versions >=16.5.0 of Node.js, polyfilling `ReadableStream` on older versions when necessary.
There are a few potential downsides to this, as React is less able to optimize flushing and execution. We can revisit that in the future though if desired.

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.

This allows to have a more streamlined API for rewrites.
Since middlewares are code and not static configurations, we can allow people to
delete query params and not just overwrite them.
**⚠️ Warning ⚠️** this is a breaking change in query parameter behavior with middlewares, but the API will make more sense now. Compare the following:
```diff
import {NextResponse} from 'next/server'
export default function middleware({ nextUrl }) {
- nextUrl.searchParams.set('ignored-query-param', '');
+ nextUrl.searchParams.delete('ignored-query-param'); // 🎉
return NextResponse.rewrite(nextUrl);
}
```
Since this is breaking change, we're adding a warning every time we find a query param that is missing, and eventually--the warning will be deleted.
I don't think we need to worry about older versions of Next.js as the current behavior is misleading: merging query parameters make sense for static rewrites, but not for middlewares where you have access to all the query parameters and can manipulate them freely.

In the web runtime, currently we use `absolute500Path || absoluteErrorPath` to act like `/_error`. This PR fixes the behavior to use the `/pages/500.js` for 500 errors and `/pages/_error.js` for 500 fallback and other errors.

which ultimately leads to a 504 Gateway Timeout error.
This is fixed by invoking the 'callback' in `_write()`.

Implements feature requested in https://github.com/vercel/next.js/issues/30805.
A few people including myself have been looking to use Relay with Next.JS and want to use the new Rust Compiler. This is my stab at an implementation.
### How it works?
Finds all `graphql` tagged template experssions and replaces them with `require`s to the file generated by Relay.
### Where I need help
- I've only worked with Rust a handful of times so I would appreciate any feedback on my use of language features.
- Is there any performance overhead to many duplicate usages of `require`? I imagine there's a cache in place but I want to be sure.
- I've added some unit tests & integration tests but I might be missing some use cases. Feel free to comment some use cases I'm not thinking about.

- [x] Integration tests added
- [ ] Documentation added
- I haven't added any docs since this is an experimental API.
## Documentation / Examples
You're expected to be running the Relay Compiler along side Next.JS when you're developing. This is pretty standard. I wouldn't expect people to have any problem with this.
### Usage
In your `next.config.js`
```js
module.exports = {
experimental: {
relay: {
language: 'typescript', // or 'javascript`
artifactDirectory: 'path/to/you/artifact/directory' // you can leave this undefined if you did not specify one in the `relay.json`
}
}
}
```

(#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.

Subtask of #31506
* move `serverBuildDir` and getter function of `publicDir` to next-server as only used place
* simplify `getMiddlewareInfo`, remove `distDir` and other params could be accessed from web server itself
Related to #31506, this PR adds `getPrerenderManifest` and `getRoutesManifest` methods to provide manifest files to the base server. In the future, we can consider making these methods async, or provide necessary manifests from the very top.

We currently have inconsistencies when working with URLs in the Edge Functions runtime, this PR addresses them introducing a warning for inconsistent usage that will break in the future. Here is the reasoning.
### The Browser
When we are in a browser environment there is a fixed location stored at `globalThis.location`. Then, if one tries to build a request with a relative URL it will work using that location global hostname as _base_ to construct its URL. For example:
```typescript
// https://nextjs.org
new Request('/test').url; // https://nextjs.org/test
Response.redirect('/test').headers.get('Location'); // https://nextjs.org/test
```
However, if we attempt to run the same code from `about:blank` it would not work because the global to use as a base `String(globalThis.location)` is not a valid URL. Therefore a call to `Response.redirect('/test')` or `new Response('/test')` would fail.
### Edge Functions Runtime
In Next.js Edge Functions runtime the situation is slightly different from a browser. Say that we have a root middleware (`pages/_middleware`) that gets invoked for every page. In the middleware file we expose the handler function and also define a global variable that we mutate on every request:
```typescript
// pages/_middleware
let count = 0;
export function middleware(req: NextRequest) {
console.log(req.url);
count += 1;
}
```
Currently we cache the module scope in the runtime so subsequent invocations would hold the same globals and the module would not be evaluated again. This would make the counter to increment for each request that the middleware handles. It is for this reason that we **can't have a global location** that changes across different invocations. Each invocation of the same function uses the same global which also holds primitives like `URL` or `Request` so changing an hypothetical `globalThis.location` per request would affect concurrent requests being handled.
Then, it is not possible to use relative URLs in the same way the browser does because we don't have a global to rely on to use its host to compose a URL from a relative path.
### Why it works today
We are **not** validating what is provided to, for example, `NextResponse.rewrite()` nor `NextResponse.redirect()`. We simply create a `Response` instance that adds the corresponding header for the rewrite or the redirect. Then it is **the consumer** the one that composes the final destination based on the request. Theoretically you can pass any value and it would fail on redirect but won't validate the input.
Of course this is inconsistent because it doesn't make sense that `NextResponse.rewrite('/test')` works but `fetch(new NextRequest('/test'))` does not. Also we should validate what is provided. Finally, we want to be consistent with the way a browser behaves so `new Request('/test')` _should_ not work if there is no global location which we lack.
### What this PR does
We will have to deprecate the usage of relative URLs in the previously mentioned scenarios. In preparation for it, this PR adds a validation function in those places where it will break in the future, printing a warning with a link that points to a Next.js page with an explanation of the issue and ways to fix it.
Although middleware changes are not covered by semver, we will roll this for some time to make people aware that this change is coming. Then after a reasonable period of time we can remove the warning and make the code fail when using relative URLs in the previously exposed scenarios.
Part of #31506, this PR moves the code of middleware handling from the base server to 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 🕺

Something [between `11.0.2-canary.5` and `11.0.2-canary.6`](https://github.com/vercel/next.js/compare/v11.0.2-canary.5...v11.0.2-canary.6) changed the behavior that logged any runtime errors in `getStaticProps` to stderr. This is only observable if `getStaticProps` has a `revalidate` value, and the build did not fail. The error has to happen in a subsequent revalidation step.
This PR reverts the change and fixes#30375.

Only chunks are allowed to write to writable. This fixes the following error in the web runtime:
```
Uncaught (in promise) TypeError: This TransformStream is being used as a byte stream, but received a string on its
writable side. If you wish to write a string, you'll probably want to explicitly UTF-8-encode it with TextEncoder.
```
It doesn't fail in the Node.js sandbox since we polyfilled this case (which should be reverted back later).

# 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 fixes#30398
By default Next will polyfill some fetch APIs (Request, Response, Header and fetch) only if fetch is not found in the global scope in certain entry points. If we have a custom server which is adding a global fetch (and only fetch) at the very top then the rest of APIs will not be polyfilled.
This PR adds a test on the custom server where we can add a custom polyfill for fetch with an env variable. This reproduces the issue since next-server.js will be required without having a polyfill for Response which makes it fail on requiring NextResponse. Then we remove the code that checks for subrequests to happen within the **sandbox** so that we don't need to polyfill `next-server` anymore.
The we also introduce an improvement on how we handle relative requests. Since #31858 introduced a `port` and `hostname` options for the server, we can always pass absolute URLs to the Middleware so we can always use the original `nextUrl` to pass it to fetch. This brings a lot of simplification for `NextURL` since we don't have to consider relative URLs no more.

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.
