Fix the wrong filename evaluation of `MIDDLEWARE_FLIGHT_MANIFEST` in required files. Besides checking the generated files, check if they're declared correctly in `required-server-files.json`
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.

Make the external `Router` state immutable, and make it so there's only one place (`set`) where it is changed and announced. This is to prepare for #33919, which ensures that we only create a new router once per tree.
Given we've spent a ton of time testing and fixing minifier bugs the majority of cases should now be covered.

Fixed lazyRoot functionality (#33290). Changed the unique id for Intersection Observers discrimination since previously they were only identified by the different rootMargins, now each being identified by the rootMargin and the root element as well
Added more Images to the test with different margins and with/without lazyRoot prop. Browser correctly initially loading two of the four Images according to the props' specifications.

* Allow scroll prevention on hash change
Currently, `scrollToHash` is performed on every hash change, even when this change is caused by `<Link scroll={false} {...props} />`.
This change prevents scrolling in this case and allows users to specify the desired scrolling behavior in the router's `hashChangeComplete` event.

In #33968, a warning was added for script tags inserted through the
next/head component. This change unintentionally included
application/ld+json scripts, which shouldn't be triggering the
warnings (as they were originally intended to catch scripts where
loading order or timing could be important). This change adds an
exception for application/ld+json scripts, so they do not log the
warning if they are included through next/head.
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.
This commit adds a development mode warning in the console
if you try to include <link rel="stylesheet"> tags in
next/head, e.g.
```
<Head>
<link ref="stylesheet" href="..." />
</Head>
```
The warning message explains that this pattern will not
work well with Suspense/streaming and recommends using a
custom Document component instead.

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.
This ensures we always transpile optional chaining and nullish coalescing with swc the same as we do [with babel](4812e22992/packages/next/build/babel/preset.ts (L97-L98)) since it can cause issues with webpack even when the node target supports these features.
The specific case this seems to cause issues with webpack is when a value is imported and optional chaining is used on the import value webpack is stripping the optional chaining cc @sokra

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.

This is just my 2nd PR so if I'm missing something please let me know.
This value has been deprecated in favor of `typeof window !== 'undefined'` a long time ago ([ref](https://github.com/vercel/next.js/pull/7651)). We should also deprecate the value in the global types as it might give the wrong assumption that this value should still be used.
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.

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] Related issues linked using `fixes #number`
- [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.

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.

The image prop `onLoadingComplete()` was unexpectedly called multiple times because it uses a [callback ref](https://reactjs.org/docs/refs-and-the-dom.html#callback-refs).
This could lead to an infinite loop if `onLoadingComplete()` calls `setState()` as demonstrated in the updated test.
The solution is to handle refs with `useRef()` and `useEffect` so `onLoadingComplete()` is called at most once per component instance.

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 🕺

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.

Fixes#32727
With this PR we introduce a new header that can be used to respond from Middleware `x-middleware-cache`. When the value of this header is set to `no-cache`, the client will **not** store the effects read from a preflight response to be used in an upcoming check.
Instead of using `Cache-Control` we are using a custom header to not mess with browser specific caching. Accepting a specific value to opt out (`no-cache`) opens the future opportunity of having other caching strategies.
This feature solves the issue of having a preflight request whose parameters can change from the client affecting the effects. For example, having a cookie that would make a middleware rewrite to one pathname or another and allowing to change that cookie from the client. In that case we'd always need to revalidate the effects on navigation synchronously.
Of course when using this feature it is possible that we add some latency on navigation so the preferred mechanism will be caching by default since it covers the most common use cases.
When the URL already contains a hash (like `/#section`) and a `Link` with `href="/"` is clicked, the page should scroll to the top on the first click. Currently, it only happens with the second click (after `#section` has been removed from the URL).

```
Uncaught (in promise) TypeError: This TransformStream is being used as a byte stream, but received a string on its

`process.env.NEXT_PHASE` was moved in https://github.com/vercel/next.js/pull/20900 to be set during `staticCheckSpan.traceAsyncFn`. I believe this to be a mistake, the NEXT_PHASE should be set earlier in the code execution.
On a personal note, this impacts an application I am developing where we rely on the environment variable `NEXT_PHASE` to be set but is `undefined` when we check it.

# 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 an issue on hydration where we rewrote using a middleware to a dynamic path. In such cases we need to run preflight to find out the middleware operation metadata.

Currently we are using `location.href` which doesn't align with the other flight request's cache key (`pathname + search`). This fix unifies it.

**Note**: This PR is applying again changes landed #31935 that were reverted from an investigation.
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.

React freeze element props and element itself in dev mode (ref: a724a3b578/packages/react/src/ReactElement.js (L194-L196))
Then next.js will reassign props with react development bundle while next-boost is enabled. Those operations are only happened in non-dev mode so it's good to remove now.

A middleware can work as a proxy intercepting requests and then performing a `fetch` to the destination adding headers to the request / response as a "man in the middle". When using `fetch` from a middleware we are not in the context of a browser so we can't really use relative URLs, they must be always absolute.
Now consider the previous case when middleware is running in *server mode*. Typically in order to know the host where we are fetching we can use the `request.nextUrl` which is given to the middleware but in this case the invoker (which is next-server) has no context of the hostname, nor the port. To solve this use case we must make the invoker of the middleware aware of the origin hostname and port.
This PR:
- Introduces `hostname` and `port` as options for `NextServer`.
- Refactors types in `NextServer` and `NextDevServer` moving type only imports to the top of the file.
- Refactors `startServer` to do a best guess on the `hostname` and `port`, passing them down.
- Exposes `.port` and `.hostname` to be retrieved from the `app`.
In an upcoming PR we will pass the host guess to the middleware to solve the relative URL issue.
`isAutoExport` should be `false` when `concurrentFeatures` is enabled.

Whenever we trigger a route change in the client we check if there route we are navigating to is affected by a middleware. When this is the case we run a preflight and in case there is an effect that tells us that the middleware is responding with content we force a _refresh_. This is fine for navigation in general but it is not ok when the change is triggered for hydration. For example, in cases where the rendered page is a dynamic page this triggers an infinite reload.
In this PR we add a test where we add a `_middleware` that proxies to a dynamic path. When making a request to `/interface/root-subrequest` there will be a middleware that simply performs a fetch against localhost for the same `/interface/root-subrequest`. The new request will skip the middleware to avoid loops and then render the dynamic page. Then client will force a change for hydration resulting in a preflight request that tells that the client must refresh because for that path there is a middleware writing content.
Then we add a fix which simply consist of checking the internal option that tells when a change is triggered for hydration and skip the preflight in such scenario.

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.

The order in which middleware must be invoked conditions its behaviour. Currently, this is not being taken into consideration for server since we are generating the array of middleware based on an arbitrary order of the middleware existing in the filesystem. This PR ships a change to generate the array of middleware preserving the order defined in the manifest.

Since `localhost` is actually an alias for `127.0.0.1` that points to loopback, we should take that into consideration at `NextURL` when we handle local URLs.
The implementation is based on [is-localhost-url](https://github.com/Kikobeats/is-localhost-url); I added some tests over local URLs variations present at the library to ensure other variations are working fine.
Additionally, I refactor some things over the code to avoid doing the same twice and added some legibility that is always welcome when you are working with URLs stuff.

The issue is that with Middleware we are introducing client compilation on a new layer. When a middleware changes (or is dropped after some time), Webpack reorganizes non-user modules as they are duplicated across different layer. This is currently triggering a full reload.
This also brings tests for HMR:
- Refresh on a Middleware change
- HMR works after a middleware compilation change.

This ensures we properly catch the rejection on route change failure in development so the dev overlay doesn't flash with the unhandled rejection. A test case isn't able to be added for this specific scenario as the unhandled rejection is fired right before the page is navigated so we can't consistently check if the rejection was unhandled or not.

This PR removes the class wrapper that we have for `TextEncoder` and `TextDecoder`. Since this is merged we will be using directly the Node version in the sandbox.
closes: https://github.com/vercel/next.js/issues/30353
According with spec, `'about:client'` is the default value is the user doesn't provide it.
It needs to add a test there, looks like there no unit tests for these classes 🤔
This fixes our `basePath` detection/replacing server-side as we were incorrectly considering `/docss` a match for a `basePath` of `/docs` which caused us to have an unexpected value in the `normalizeLocalePath` function.

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.

This changes the check for whether a rewrite is internal or if it should be proxied. Currently it checks if `protocol` is unset, which is only the case for relative URLs or localhost. This means that requests where there is a hostname set, or if localhost is specified in another way such as `127.0.0.1`, then it will be proxied, which potentially causes a proxy loop or ssl error. This PR changes the test so that it also checks if the hosts match, and only proxies if they are different.

* fix(30724): clear "x-middleware-next" header when chaining middlewares

The `resource` argument[^1] in fetch may also be an instance of URL (or any other stringifiable value) but the sandbox variant of middlewares doesn't support that.
```js
export async function middleware(req, ev) {
await fetch(new URL('https://www.googleapis.com/oauth2/v3/certs'), {
redirect: 'manual',
method: 'GET',
})
return new Response(JSON.stringify({}), { status: 200 });
}
```
This is fixing the use of e.g. URL instance in `fetch`.

This ensures the `asPath` and `req.url` values are normalized correctly for fallback pages with i18n in minimal mode. This also copies the minimal mode test suite to run against i18n as well. This also fixes an issue where rewrite params weren't passed correctly on the client when no params were already used in the destination.

Fixes https://github.com/vercel/next.js/issues/30839
When libraries are required outside of the middleware function context and they do checks such as `a instanceof Uint8Array` since the constructors are different between the two contexts they'll always yield false.
This is a problem for libraries validating user input as well as the WebCryptoAPI polyfill used outside of Edge Functions.
- Fixes#30477
- Fixes#30911
This is only a problem for the sandbox runtime, not when ran inside an Edge Function.
Fixes https://github.com/vercel/next.js/issues/31013
My understanding is that there are currently two functions `Router.change` and `Router.prefetch` leading to `Router._preflightRequest` and they pass `options.as` URL differently regarding base path.
In this PR, such difference will be handled in `Router._preflightRequest` to add base path before actually fetching.
Thanks for the review!
P.S.
Since middleware feature is a relatively new, official maintainers might not want external contributions around this area at this stage.
I totally understand such situation, so please let me know if that's the case. I can look for other issues to investigate instead.

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.

Fixes: #31104
This effecting users who are using expo with next (`@expo/next-adapter`) since react-native use `.web`, `.ios` and `.android` to identify platform. [Reference](https://docs.expo.dev/guides/using-electron/#%F0%9F%A7%B8-behavior)
Change `document.web.js` to `document-web.js` as fallback page in web runtime
Adds support for render props to the `<Main>` component, when using the [functional custom `Document`](https://github.com/vercel/next.js/pull/28515) style. This allows you to write something like this:
```tsx
export default function Document() {
const jsxStyleRegistry = createStyleRegistry()
return (
<Html>
<Head />
<body>
<Main>
{content => (
<StyledJsxWrapper registry={jsxStyleRegistry}>
{content}
</StyledJsxWrapper>
)}
</Main>
<NextScript />
</body>
</Html>
)
}
```
In functional document components, this allows the `<App>` to be wrapped, similar to `enhanceApp` (which is only available via `getInitialProps`, which is not supported by functional document components). The primary use for this is for integrating with 3rd party CSS-in-JS libraries, allowing them to attach an `useFlush` handler to [support React 18](https://github.com/reactwg/react-18/discussions/110):
```tsx
import { unstable_useFlush as useFlush } from 'next/document'
export default function StyledJsxWrapper({ children, registry }) {
useFlush(() => {
/* ... */
})
return (
<StyleRegistry registry={registry}>
{children}
</StyleRegistry>
)
}
```
Support for `useFlush` will be added in a follow up PR.
Based on feedback from @flybayer, this changes the `warn - ` to `info -` for the "Disabled SWC" message.

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.

By conditionally importing `react-dom/server` under the web runtime and reusing `renderToReadableStream` instead of `renderToStaticMarkup`, we can get rid of the legacy browser React DOM server from the runtime. ~Furthermore we can make the build target `es6` for the SSR middleware, and make some code paths tree-shakable (done in another PR).~
Together this makes the runtime ~32kb smaller.

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.
