Follow up for #39953
Detect invalid gSSP/gSP exports in page or layout client components in build time instead of checking them in runtime, in this way we can:
* Error to user eariler with traced file path, help user find the incorrect usage easier
* Make the flight client loader simpler, headless, aligned with react

Follow-up to https://github.com/vercel/next.js/pull/40076 this ensures we handle rendering correctly when the URL doesn't match the edge function exactly e.g. when rewriting since it looks like we don't currently have access to the `x-matched-path` header like we do for serverless functions.

This updates to handle detecting `getStaticProps`/`getServerSideProps` correctly during build when `experimental-edge` is being used. This also fixes not parsing dynamic route params correctly with the edge runtime and sets up the handling needed for the static generation for app opened in the below mentioned PR.

This is intended to refactor the router code to reduce the overhead of executing routes. This is related to #32314 that may help reduce the memory overhead as this also replaced the `Set` with a `WeakMap`.

This PR updates the `next/future/image` component so that CSS `filter` is never needed. Previously, we used SVG to blur for prod and CSS to blur for dev, but now we use SVG for both.
This required a shared function `getImageBlurSvg()` used between both client and server because `next dev` doesn't create Data URIs and instead defers blur generation until request time. So we also need to defer svg generation to request time (on the server) during next dev.
This is the first step to removing `<noscript>` completely (see #39736).
Typescript published 4.8.2 today and it fails CI, bump our typescript version to 4.8.2 and tweak some typings to make existing e2e typescript tests work properly
* Bump web-vitals from 3.0.0-beta to 3.0.0 stable for typing fix (there's an undefined type but it wasn't caught by ts 4.7), also force compiled it as CJS for pre-compiled
* Bump ncc to 3.34.0 for ts-loader compatibility for new typescript version, ncc 3.33.x cannot work with ts 4.8
* Update pre-compiled
### Problem
esm modules imports from client components will be compiled to `m = import('module-name')` when webpack bundles them for server components flight rendering. In this case, they will all become async modules since dyanmic imports will return a promise which react flight cannot handle it then results into module resolving error on server flight rendering.
### Solution
* React flight renderer supports handling async modules in https://github.com/facebook/react/pull/25138
* On next.js side leverage the module proxy change for each client reference, to make sure it always resolve the correct client module
The idea is wrapping each module with a module proxy, and if the module is async and accessed as thenable, it will return a new module reference with `async` label to tell react to handle it as async modules:
exported client reference `*` --> not async module (non thenable) --> original module reference `''`
exported client reference `*` --> it's async module (thenable) --> wrapped module reference `'*'` with `async` label
### Note
Since we need to check if user having incorrect gSSP/gSP specifying in layout client componet, so we still need to parse it and assign those info to the proxy (Does client module containing `ssr`, `ssg` exports). Otherwise the proxy will return the cached module reference
For historical reasons, Next.js has been falling back to polyfill certain Node.js APIs in the browser. `webpack` itself stopped doing it, and so should Next.js. This might unexpectedly break some packages in the ecosystem though, so it is being introduced as an experimental flag. These imports will now throw a `Module not found` error and the package maintainer should make sure that the library isn't relying on these Node.js APIs when the package is meant for browser usage.
Let's take a look at a common example, the `crypto` API, which can be imported as `import crypto from "crypto"` but [should already be available in browsers](https://caniuse.com/cryptography). Until now, Next.js has fallen back to use a polyfilled version for the import, which resulted in a bundle-size increase.
```js
import crypto from 'crypto'
import { useEffect } from 'react'
export default function Page() {
useEffect(() => {
console.log(crypto)
}, [])
}
```
it imports `crypto`, which currently resolves to [`crypto-browserify`](https://www.npmjs.com/package/crypto-browserify).
So the bundle will include `crypto-browserify` as well:
```sh
Page Size First Load JS
┌ ○ / 131 kB 213 kB # <--
└ ○ /404 194 B 82.2 kB
+ First Load JS shared by all 82 kB
├ chunks/framework-bcc2dc0ea27ab0c6.js 45.1 kB
├ chunks/main-dc2421aef72299b4.js 35.4 kB
├ chunks/pages/_app-a85935458980c5c2.js 708 B
└ chunks/webpack-9b312e20a4e32339.js 836 B
```
Here, we can just remove the import, as we are [safely accessing](https://nextjs.org/docs/migrating/from-create-react-app#safely-accessing-web-apis) the [Crypto Web API](https://caniuse.com/cryptography):
```diff
- import crypto from 'crypto'
import { useEffect } from 'react'
export default function Page() {
useEffect(() => {
console.log(crypto)
}, [])
}
```
Which will reduce the bundle size:
```sh
Page Size First Load JS
┌ ○ / 269 B 82.2 kB # <--
└ ○ /404 194 B 82.1 kB
+ First Load JS shared by all 81.9 kB
├ chunks/framework-bcc2dc0ea27ab0c6.js 45.1 kB
├ chunks/main-dc2421aef72299b4.js 35.4 kB
├ chunks/pages/_app-a85935458980c5c2.js 708 B
└ chunks/webpack-fd82975a6094609f.js 727 B
```
This is harder to detect if the `crypto` import is in a third-party package though. By setting `experimental: { fallbackNodePolyfills: false }`, Next.js will now fail at build-time and should show where the unnecessary import comes from, so the developer can reach out to the package maintainer to fix this issue.
Note: There might be differences between the living standard and some of these older polyfills, so you have to make sure your code works well without the polyfilled version.

## Bug
Adding a components folder inside a catch-all page triggers the error: "Catch-all must be the last part of the URL", having the component outside works, for example `app/[...slug]/components/*.tsx` fails but `app/components/*.tsx` works as expected.
### Fix
The reason it errors because they're treated as route and inserted into the url node tree where they shouldn't be treated in this way. Adding a helper to skip collecting and normailizing every file as route for app dir, but only do it for page files

Follow-up to #39758, this PR makes sure that CSS imports (both global and CSS modules) from client components are not handled by mini-css-extract's HMR logic. Instead, we trigger a server component update and let the client to refetch the RSC payload.
However, we are still leveraging the mini-css-extract plugin to emit CSS assets. So in this PR we add a new pitch loader to calculate the original file hash, but replace the final content to eliminate HMR logic but only keep the hash (so hot reloader can keep tracking that).

This PR is a follow up to PR #39190 so that we can dynamically set the `feComponentTransfer` when we know the image doesn't have transparency (at this time its just jpeg).
We also set the stdDeviation to 1 and the viewbox to the placeholder's width/height to avoid any rounding issues.
Finally, we also fix the conversion from `objectPosition` to `backgroundPosition` because they have different default values according to the spec.
As noticed in https://github.com/markdoc/markdoc/issues/131 it seems we are incorrectly disposing active entries causing HMR to fail after the configured `maxInactiveAge`. To fix this instead of only updating lastActiveTime for one compiler type's entry we update all active compiler types for the active entry.
This also updates an existing test to catch this by waiting the `maxInactiveAge` before attempting a change that should trigger HMR.

Fixes: https://github.com/markdoc/markdoc/issues/131
Removed the hack of client-side CSS injection via `chunk`. Instead collect them with the manifest plugin and SSR them as link tags.
Next step is to adjust HMR to not relying on mini-css-extract plugin and webpack.
Follow-up to #39826 this skips ensuring the /500 page when in development as it's not used since we use the error overlay instead. This also fixes the case where we don't clear the stalled timeout debug log when an error is thrown during ensuring.
This updates the stalled ensure log to use debug instead the log isn't really actionable by the user and is more so meant for debugging purposes.

# Bug
I would assume that this should be generated from TypeScript, but based on the [original PR](https://github.com/vercel/next.js/pull/38498/files) it wasn't clear that there was a way to generate these automatically.
Fixes the type of `styledComponents. topLevelImportPaths` and `styledComponents.meaninglessFileNames` so that it matches the [TypeScript type](https://github.com/vercel/next.js/blob/canary/packages/next/server/config-shared.ts#L457).
This was causing a warning here:
```
warn - Invalid next.config.js options detected:
- The value at .compiler.styledComponents must be a boolean but it was an object.
- The value at .compiler.styledComponents.meaninglessFileNames must be a boolean but it was an array.
- The value at .compiler.styledComponents must match exactly one schema in oneOf.

When a user tried to have the following Edge Function:
```ts
export default () => fetch("https://example.vercel.sh");
```
The Edge Function were failing.
Why is that?
When `fetch` was called, an implicit `Accept-Encoding` header was added
to allow the origin to return a compressed response. Then, the origin
will set the `Content-Encoding` header in the response, to let the
client know that the body needs to be decompressed in order to be read.
That creates an issue though: `response.body` will be a
`ReadableStream<Uint8Array>`, or, a stream that contains binary data
that decodes into _the uncompressed data_ (or, plain text!).
What it means, is that `response.body` is uncompressed data, while
`response.headers.get('content-encoding')` is marking the response body
as compressed payload. This confuses the HTTP clients and makes them fail.
This commit removes the `content-encoding`, `transfer-encoding` and
`content-length` headers from the response, as the Next.js server _always_
streams Edge Function responses.

The PR fixes#39706 by adding `avif` mime type directly to `send`. The PR also removes the previous avif workaround for image optimizer.
Note: The PR is still a workaround for now. I will submit a PR to `pillarjs/send` to help them update `mime` to fix the issue once and for all. But now `send.mime.define` just works.

Upgrade experimental React, and render link tags directly in the tree during development. The client bundle won't import CSS anymore, and server CSS imports will be transpiled into no-op strings just for HMR to use.

Currently Edge SSR routes are added to both `routedPages` (catch-all page render routes) and `edgeRoutesSet` (catch-all edge function routes). This causes the request to be handled by both and results in an error (the Node server can't execute the Edge SSR route as a regular page).
Another fix is to make sure Edge Function routes are sorted too, so `/foo` can be caught before dynamic ones like `/[id]`.

Use flush effects to custom apply css-in-js solution to app. Re-introduce flush effects to app-render, and remove default support of styled-jsx in `app/`. So that users will choose their own css-in-js solution if they need any customization. styled-jsx won't appear in client bundle if you didn't use it.
For now we have to inject the initial styles before `</head>` to avoid hydration errors. Later on we can remove this once react can handle it.
- [x] inject styles before end of head element
- [x] add tests
This ensures we properly leverage the `assetPrefix` for `app`. Note for reviewing the test changes are mostly spacing so hiding that may help.

x-ref #39199
The change in #39199 isn't correct. Middleware manifest should only contain middleware route, so that when router navigates, it only try to apply middleware instead of checking all edge routes. This PR also changes the middleware manifest global value from array to object for easier access

Previous next versions supported nested version of middleware, now we simplify it to one global middleware. This PR clarify the middleware and edge functions usage in dev server
This corrects some unhandledRejection errors showing when a connection is canceled with the edge runtime since the changes needed for 14463ddd10. This also adds a regression test to ensure we don't have these class of errors in our middleware tests.

This line was introduced in #38862 to the base server but should only be useful for the Node.js server:
```js
addRequestMeta(req, '__NEXT_CLONABLE_BODY', getClonableBody(req.body))
```
It also introduces polyfill of `stream` to the edge server.
Here we add an abstract method to handle it differently, where only `__NEXT_INIT_QUERY` is used.

This PR updates the Edge Runtime to use a new version that loads dependencies differently. This addresses https://github.com/vercel/next.js/pull/38766 so `instanceof` works as expected.
It involved a few code changes, mostly regarding to types. The most important change is that the `Runner` function in the sandbox doesn't take a `ReadableStream` as `body` anymore since this implies creating the instance on "node land" and makes the runtime `fetch` function not to be able to compare with `ReadableStream` using `instanceof`. Instead we introduce a "clonable body" abstraction that allows to create the `ReadableStream` from `Readable` by using the edge runtime primitive which would hold the correct prototype.
Also, this PR changes the way we pre-compile the Edge Runtime to adapt it to the new version.
`experimental.optimizeCss` from `next.config.js` can be an object containing the critters' option:
70a53e0789/packages/next/server/post-process.ts (L224-L232)
The PR corrects the ajv schema and the type definition of `experimental.optimizeCss`.
## What’s in there?
This PR brings more consistency in how errors and warnings are reported when running code in the Edge Runtime:
- Dynamic code evaluation (`eval()`, `new Function()`, `WebAssembly.instantiate()`, `WebAssembly.compile()`…)
- Usage of Node.js global APIs (`BroadcastChannel`, `Buffer`, `TextDecoderStream`, `setImmediate()`...)
- Usage of Node.js modules (`fs`, `path`, `child_process`…)
The new error messages should mention *Edge Runtime* instead of *Middleware*, so they are valid in both cases.
It also fixes a bug where the process polyfill would issue a warning for `process.cwd` (which is `undefined` but legit). Now, one has to invoke the function `process.cwd()` to trigger the error.
It finally fixes the react-dev-overlay, where links from middleware and Edge API route files could not be opened because of the `(middleware)/` prefix in their name.
About the later, please note that we can’t easily remove the prefix or change it for Edge API routes. It comes from the Webpack layer, which is the same for both. We may consider renaming it to *edge* instead in the future.
## How to test?
These changes are almost fully covered with tests:
```bash
pnpm testheadless --testPathPattern runtime-dynamic
pnpm testheadless --testPathPattern runtime-with-node
pnpm testheadless --testPathPattern runtime-module
pnpm testheadless --testPathPattern middleware-dev-errors
```
To try them out manually, you can write a middleware and Edge route files like these:
```jsx
// middleware.js
import { NextResponse } from 'next/server'
import { basename } from 'path'
export default async function middleware() {
eval('2+2')
setImmediate(() => {})
basename()
return NextResponse.next()
}
export const config = { matcher: '/' }
```
```jsx
// pages/api/route.js
import { basename } from 'path'
export default async function handle() {
eval('2+2')
setImmediate(() => {})
basename()
return Response.json({ ok: true })
}
export const config = { runtime: 'experimental-edge' }
```
The expected behaviours are:
- [x] dev, middleware/edge route is using a node.js module: error at runtime (logs + read-dev-overlay):
```bash
error - (middleware)/pages/api/route.js (1:0) @ Object.handle [as handler]
error - The edge runtime does not support Node.js 'path' module.

## Notes to reviewers
Edge-related errors are either issued from `next/server/web/sandbox/context.ts` file (runtime errors) or from `next/build/webpack/plugins/middleware-plugin.ts` (webpack compilation).
The previous implementation (I’m pleading guilty here) was way too verbose: some errors (Node.js global APIs like using `process.cwd()`) could be reported several times, and the previous mechanism to dedupe them (in middleware-plugin) wasn’t really effective.
Changes in tests are due to renaming existing tests such as `test/integration/middleware-with-node.js-apis` into `test/integration/edge-runtime-with-node.js-apis`. I extended them to cover Edge API route.
@hanneslund I’ve pushed the improvement you did in https://github.com/vercel/next.js/pull/38289/ one step further to avoid duplication.
Fixes a bug where `import { nanoid } from 'nanoid'` broke the tests.

Starting in Node.js 18, the `fetch` global was made available and that caused the squoosh implementation to assume it was on a web browser and try to fetch the wasm file instead of reading it from the filesystem. This PR deletes the code trying to fetch since we know that squoosh only runs in the Image Optimization API, not the browser.
- Fixes#38020
- Enables a test that was disabled in #38460
## How to reproduce
1. create a next.js app with a middleware (or an edge route) that imports a node.js module:
```js
// middleware.js
import { NextResponse } from 'next/server'
import { basename } from 'path'
export default async function middleware() {
basename()
return NextResponse.next()
}
```
2. deploy it to vercel with `vc`
3. go to the your function logs in Vercel Front (https://vercel.com/$user/$project/$deployment/functions)
4. in another tab, query your application
> it results in a 500 page:
<img width="517" alt="image" src="https://user-images.githubusercontent.com/186268/179557102-72568ca9-bcfd-49e2-9b9c-c51c3064f2d7.png">
> in the logs you should see:
<img width="1220" alt="image" src="https://user-images.githubusercontent.com/186268/179557266-498f3290-b7df-46ac-8816-7bb396821245.png">
## Expected behavior
The route should fail indeed in a 500, because Edge runtime **does not support node.js modules**. However the error in logs should be completely different:
```shell
error - Error: The edge runtime does not support Node.js 'path' module.
Learn More: https://nextjs.org/docs/messages/node-module-in-edge-runtime
```
## Notes to reviewers
I introduced this issue in #38234.
Prior to the PR above, the app would not even build, as we were checking imported node.js module during the build with AST analysis.
Since #38234, the app would build and should fail at runtime, with an appropriate error.
The mistake was to declare `__import_unsupported` function in the sandbox's context, that is only used in `next dev` and `next start`, but not shipped to Vercel platform.
By loading it inside webpack loaders (both middleware and edge route), we ensure it will be defined on Vercel as well.
The existing test suite (`pnpm testheadless --testPathPattern=runtime-module-error`) covers them.

# Description
Hi guys! First all, thanks for provide a way to use some custom external cache resource for ISR feature. _(done here: https://github.com/vercel/next.js/pull/37258 and https://github.com/vercel/next.js/pull/37326)_
I managed to get it working by creating my custom external cache resource _(using redis)_ that implements the new `CacheHandler`. _(overriding my own `get` and `set` methods and using the FileSystemCache as fallback as well)_
I'm planning to release some kind of plugin to encapsulate and parse the client's `next.config.js` and bring an initial support for redis using this new Next.js feature.
So, I really don't know if this was intentional, but I noticed that the new `incrementalCacheHandlerPath` prop wasn't passed to the `IncrementalCache` instance in `base-server`.
This PR just connects the wires for this feature, and also provide the default value (`undefined`) to the relative experimental prop config. _(to avoid the warnings as shown below)_

This outputs a separate manifest for leveraging during deploy to handle the new app outputs. Also ensures dynamic routes from `app` our output in the `routes-manifest` correctly along with fixing the `react-dom` import.
x-ref: https://github.com/vercel/next.js/pull/37551
- Remove cache value that was incorrectly nested deeper
- Remove extra useEffect (already applied during hydration based on the `useReducer` input)
- Add dynamic parameter name into the tree
Follow-up to #37551, cleans up some code and prepares for catch-all and optional catch-all routes.
## Client-side router for `app` directory
This PR implements the new router that leverages React 18 concurrent features like Suspense and startTransition.
It also integrates with React Server Components and builds on top of it to allow server-centric routing that only renders the part of the page that has to change.
It's one of the pieces of the implementation of https://nextjs.org/blog/layouts-rfc.
## Details
I'm going to document the differences with the current router here (will be reworked for the upgrade guide)
### Client-side cache
In the current router we have an in-memory cache for getStaticProps data so that if you prefetch and then navigate to a route that has been prefetched it'll be near-instant. For getServerSideProps the behavior is different, any navigation to a page with getServerSideProps fetches the data again.
In the new model the cache is a fundamental piece, it's more granular than at the page level and is set up to ensure consistency across concurrent renders. It can also be invalidated at any level.
#### Push/Replace (also applies to next/link)
The new router still has a `router.push` / `router.replace` method.
There are a few differences in how it works though:
- It only takes `href` as an argument, historically you had to provide `href` (the page path) and `as` (the actual url path) to do dynamic routing. In later versions of Next.js this is no longer required and in the majority of cases `as` was no longer needed. In the new router there's no way to reason about `href` vs `as` because there is no notion of "pages" in the browser.
- Both methods now use `startTransition`, you can wrap these in your own `startTransition` to get `isPending`
- The push/replace support concurrent rendering. When a render is bailed by clicking a different link to navigate to a completely different page that still works and doesn't cause race conditions.
- Support for optimistic loading states when navigating
##### Hard/Soft push/replace
Because of the client-side cache being reworked this now allows us to cover two cases: hard push and soft push.
The main difference between the two is if the cache is reused while navigating. The default for `next/link` is a `hard` push which means that the part of the cache affected by the navigation will be invalidated, e.g. if you already navigated to `/dashboard` and you `router.push('/dashboard')` again it'll get the latest version. This is similar to the existing `getServerSideProps` handling.
In case of a soft push (API to be defined but for testing added `router.softPush('/')`) it'll reuse the existing cache and not invalidate parts that are already filled in. In practice this means it's more like the `getStaticProps` client-side navigation because it does not fetch on navigation except if a part of the page is missing.
#### Back/Forward navigation
Back and Forward navigation ([popstate](https://developer.mozilla.org/en-US/docs/Web/API/Window/popstate_event)) are always handled as a soft navigation, meaning that the cache is reused, this ensures back/forward navigation is near-instant when it's in the client-side cache. This will also allow back/forward navigation to be a high priority update instead of a transition as it is based on user interaction. Note: in this PR it still uses `startTransition` as there's no way to handle the high priority update suspending which happens in case of missing data in the cache. We're working with the React team on a solution for this particular case.
### Layouts
Note: this section assumes you've read [The layouts RFC](https://nextjs.org/blog/layouts-rfc) and [React Server Components RFC](https://reactjs.org/blog/2020/12/21/data-fetching-with-react-server-components.html)
React Server Components rendering leverages the Flight streaming mechanism in React 18, this allows sending a serializable representation of the rendered React tree on the server to the browser, the client-side React can use this serialized representation to render components client-side without the JavaScript being sent to the browser. This is one of the building blocks of Server Components. This allows a bunch of interesting features but for now I'll keep it to how it affects layouts.
When you have a `app/dashboard/layout.js` and `app/dashboard/page.js` the page will render as children of the layout, when you add another page like `app/dashboard/integrations/page.js` that page falls under the dashboard layout as well. When client-side navigating the new router automatically figures out if the page you're navigating to can be a smaller render than the whole page, in this case `app/dashboard/page.js` and `app/dashboard/integrations/page.js` share the `app/dashboard/layout.js` so instead of rendering the whole page we render below the layout component, this means the layout itself does not get re-rendered, the layout's `getServerSideProps` would not be called, and the Flight response would only hold the result of `app/dashboard/integrations/page.js`, effectively giving you the smallest patch for the UI.

Note: the commits in this PR were mostly work in progress to ensure it wasn't lost along the way. The implementation was reworked a bunch of times to where it is now.

## What's in there?
The Edge runtime [does not support Node.js modules](https://edge-runtime.vercel.app/features/available-apis#unsupported-apis).
When building Next.js application, we currently fail the build when detecting node.js module imported from middleware.
This is an blocker for using code that is conditionally loading node.js modules (based on platform/env detection), as @cramforce reported.
This PR implements a new strategy where:
- we can build such middleware/Edge API route code **with a warning**
- we fail at run time, with graceful errors in dev (console & react-dev-overlay error)
- we fail at run time, with console errors in production
## How to test?
All cases are covered with integration tests.
To try them live, create a simple app with a page, a `middleware.js` file and a `pages/api/route.js`file.
Here are iconic examples:
### node.js modules
```js
// middleware.js
import { NextResponse } from 'next/server'
// static
import { basename } from 'path'
export default async function middleware() {
// dynamic
const { basename } = await import('path')
basename()
return NextResponse.next()
}
export const config = { matcher: '/' }
```
```js
// pags/api/route.js
// static
import { isAbsolute } from 'path'
export default async function handle() {
// dynamic
const { isAbsolute } = await import('path')
return Response.json({ useNodeModule: isAbsolute('/test') })
}
export const config = { runtime: 'experimental-edge' }
```
Desired error (+ source code highlight in dev):
> The edge runtime does not support Node.js 'path' module

Desired warning at build time:
> A Node.js module is loaded ('path' at line 2) which is not supported in the Edge Runtime.

## Notes to reviewers
The strategy to implement this feature is to leverages webpack [externals](https://webpack.js.org/configuration/externals/#externals) and run a global `__unsupported_module()` function when using a node.js module from edge function's code.
For the record, I tried using [webpack resolve.fallback](https://webpack.js.org/configuration/resolve/#resolvefallback) and [Webpack.IgnorePlugin](https://webpack.js.org/plugins/ignore-plugin/) but they do not allow throwing proper errors at runtime that would contain the loaded module name for reporting.
`__unsupported_module()` is defined in `EdgeRuntime`, and returns a proxy that's throw on use (whether it's property access, function call, new operator... synchronous & promise-based styles).
However there's an issue with error reporting: webpack does not includes the import lines in the generated sourcemaps, preventing from displaying useful errors.
I extended our middleware-plugin to supplement the sourcemaps (when analyzing edge function code, it saves which module is imported from which file, together with line/column/source)
The react-dev-overlay was adapted to look for this additional information when the caught error relates to modules, instead of looking at sourcemaps.
I removed the previous mechanism (built by @nkzawa ) which caught webpack errors at built time to change the displayed error message (files `next/build/index.js`, `next/build/utils.ts` and `wellknown-errors-plugin`)
since we no longer have a single compiler for browser & edge, we can enable
source map generation by default for all edge functions. This would make it
much easier to debug and understand what's happening when deploying to prod
as the log statements will show us the actual code location instead of post
bundling and minified location.
This also removes the experimental flag as it's not needed anymore.

This PR corrects a mistake where a negative number could pass, as a number greater than 0.
This is due to negative numbers being a truthy value in JS.

Right now if people will accidentally export a typo like `runtime: 'experimental-egde'` we will fail silently.
This commit ensures we will throw and fail loudly when such typos occur.

Currently `renderToReadableStream` will be called whenever the component is re-rendered, but the result should actually be cached (per request).
Thanks to @sebmarkbage for pointing out.

Minor fix to recent experimental configs. While the latest next.js includes support for those experimental features, currently it emits warnings like
```
You have defined experimental feature (swcPlugins) in next.config.js that does not exist in this version of Next.js
```
As validation checks the existence of default values even though config itself allows them to be optional. PR does not attempt to change validation logics, only amends it by having empty default values.

avoid fetching a chunk for api endpoints on middleware redirect.
This still makes a request to the data endpoint, not sure if this is a good idea,
but a rewrite _can_ happen from that data request.

* Refactor `runDependingOnPageType`
* Throw specific error when the compiled middleware cannot be found
* Do not render `MiddlewareNotFoundError` on dev
* Allow to invalidate compilers by type
* Show compile errors when middleware fails to build
* Add tests
This PR introduces a new experimental component, `next/future/image`, which is inspired by the existing experimental `layout="raw"`.
The difference is that much of the code has been deleted in order to reduce client-side code as well as reduce complexity:
- No `layout` prop
- No `loader` config (although `loader` prop works)
- No `IntersectionObserver`, use native `loading="lazy"`
- No `lazyBoundary`
- No `lazyRoot`
- No `fill` (yet) so width & height are required
- No `objectFit` (use `style` instead)
- No `objectPosition` (use `style` instead)
This improves performance because native `loading="lazy"` doesn't need to wait for React Hydration and client-side JS.
In a future PR, we will modify `next/image` to remove `layout="raw"` since this new component supersedes it.

This allows configuring / overriding the default options of the `styled-components` swc transform and allows using the `css` prop support, which was already implemented, but not available.
Edit: made the CSS prop transform run before the display name, so it gets picked up by that and receives the (deterministic) name.
