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.
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

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.

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.
* Added 'rootEl' oprional property to next/Image component resembling 'root' option of the Intersection Observer API
* changed 'rootEl' to 'lazyBoundary' and its type as well
* added test, fixed initial root detection
* Update test/integration/image-component/default/test/index.test.js

* prop names changed
* added 'lazyroot' prop to the documentation
* removed unused import
* Apply suggestions from code review
* Update docs with lazyRoot added in 12.0.9

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.
