### Issue
When import an esm package in client component, and use it in server
component page, it will fail to SSR but render successfully on client.
It's because the import to esm package will make the client chunk become
an **async module** since esm module will be treated as **async**.
```
page (serve component) -> local module (client) -> external dependency (esm)
```
Then in react SSR layer, it need the module type information of that
chunk, async or not for react so that react could unwrap the async
module from `Promise` properly when SSR.
### Solution
We need to mark the client entries which are effected by async/esm
modules that becoming **async** as `async: true` in SSR manifest.
Since flight manifest plugin is only running against client compiler,
which doesn't have those module information from server compiler. So we
collect the async modules from the **server** compiler **client** layer
from flight entry client plugin, then leverage the collection to detect
if a module is async in flight manifest plugin for react.

Updates the output path so it's the same as when font files are imported
in CSS: `url(./font.woff2)`
Also adds missing font types to next package.

This updates to ensure we properly error during static generation when a
non-dynamic SSR error is thrown so that unexpected errors are not
tolerated. This also fixes the static generation async storage not being
shared correctly due to different instances being created during
bundling.
Moves font related types to `next/font` so they can be reused in font
loaders.
Adds an argument to font loaders, the relative path from the app root to
the module consuming the loader. Needed for resolving local files
relative to the module calling it. Also used to improve error message.
Adds `@next/font/local` font loader. Similar to `@next/font/google` but
used to host locally downloaded font files.
For some context:
[https://vercel.slack.com/archives/CGU8HUTUH/p1662124179102509](https://vercel.slack.com/archives/CGU8HUTUH/p1662124179102509)
Continuation of #40221 and #40227
Adds `experimental.fontLoaders`.
SWC next-font-loaders (#40221) transforms font loader (e.g. #40227) call
expressions into an import with the function call arguments as a query.
The imports will be matched by `next-font-loader`. It runs the
configured font loaders - emits font files and returns CSS. Exports are
added, and the font-family is made locally scoped. The returned CSS is
turned into a CSS module with `css-loader` which lets you consume the
font-family.
`FontLoaderManifestPlugin` creates a manifest of the preloaded font
files for each entrypoint. Preload/preconnect are then added in
`_document.tsx` if any font files were found for that path.

`config.experimental.serverComponents` is currently required to be
enabled or disabled together with `config.experimental.appDir` (which
means `serverComponents === appDir` otherwise it will throw) so there is
no reason to keep both of them. This PR removes `serverComponents` from
Next.js and only rely on `appDir` instead.

This PR changes the external module resolution to eagerly bundle
node_modules, and some specific Next.js internal modules, if on the
`WEBPACK_LAYERS.server` layer. While resolving corresponding packages,
we use the `react-server` export condition (fallbacks to default).
A follow-up PR will be adding a Next.js option to opt-out specific
packages from being bundled on the server layer.

Follow up for https://github.com/vercel/next.js/pull/40415
Remove internal next client api determination, fully relying on `'client'` directive.
Change `.client.js` extension to `.js ` in tests, remove legacy / unused test files
## Feature
Change server components convention from using `.server.js` / `.client.js` file extension to determine it's a server or client component to using `'client'` js literal as a directive for determine client components boundary.
React RFC: https://github.com/reactjs/rfcs/pull/189
New behavior doesn't consume `.server.js` as server components any more, if you're enabling `serverComponents` flag, every `page.js` in app dir will become server components by default. If you adding a `'client'` directive to the page, then that page will become a client component. This rule also applies to the normal js components, client components will require a `'client'` directive to indicate its identity, instead of having a `.client.js` extension.

This is an initial implementation of the Server Components SWC
transformer. For the server graph, it detects client entries via the
`"client"` directive and transpile them into module reference code; for
the client graph, it removes the directives. And for both graphs, it
checks if there is any invalid imports for the given environment and
shows proper errors.
With that added, we can switch from `next-flight-client-loader` to
directly use the SWC loader in one pass. Next step is to get rid of the
`.client.` extension in other plugins.

Found that the cause was that `React.useId()` returns the same value across requests whereas it was being used to create a unique key. On further inspection that code could be removed altogether as `id` was not used client-side and the `rscCache` map is no longer needed as the flight instance is already being created per request so it can live in the context of the request execution.

This serves to add support for [Subresource
Integrity](https://developer.mozilla.org/en-US/docs/Web/Security/Subresource_Integrity)
hashes for scripts added from the new app directory. This also has
support for utilizing nonce values passed from request headers (expected
to be generated per request in middleware) in the bootstrapping scripts
via the `Content-Security-Policy` header as such:
```
Content-Security-Policy: script-src 'nonce-2726c7f26c'
```
Which results in the inline scripts having a new `nonce` attribute hash
added. These features combined support for setting an aggressive Content
Security Policy on scripts loaded.

For edge routes in app dir, we passed the page name as url so that the
url will be incorrect:
* a non-dynamic route `/dashboard` will become `/dashboard/page`
* a dynamic route `/dynamic/[id]` with url `/dyanmic/123` will still hit
`/dynamic/page/[id]/page`
This PR uses normalized `params.page` with interoplated as correct
pathname for the page.
Given the change in #40076, when a middleware rewrites into an Edge
API route and changes the querystring, the changed querystring does
not appear in the incoming NextRequest object in the Edge API route
```ts
// middleware.ts
export function middleware(req: NextRequest) {
const url = req.nextUrl;
url.pathname = "/api/hello";
url.searchParams.set("foo", "bar");
return NextResponse.rewrite(url);
}
// pages/api/hello.ts
import { NextRequest } from "next/server";
export default function handler(req: NextRequest) {
return NextResponse.json(req.nextUrl.searchParams.get("foo"));
}
export const config = { runtime: "experimental-edge" };
```
Our expectation when requesting `/api/hello` is to see `"bar"`,
but instead we are getting `null` back.
This commit fixes this issue by reading the given `query` instead of using
the initial querystring provided with the user request (prior to rewriting)

Makes it possible to switch between edge/server runtime in dev without
breaking the server.

#### middleware-plugin.ts
`middlewareManifest` moved from module scope to local scope. Stale state
from earlier builds ended up in `middleware-manifest.json`. Functions
that changed from edge to server runtime stayed in the manifest as edge
functions.
#### on-demand-entry-handler.ts
When a server or edge entry is added we check if it has switched
runtime. If that's the case the old entry is removed.
#### Reproduce
Create edge API route and visit `/api/hello`
```js
// pages/api/hello.js
export const config = {
runtime: 'experimental-edge',
}
export default () => new Response('Hello')
```
Change it to a server api route and visit `/api/hello`, it will explode.
```js
// pages/api/hello.js
export default function (req, res) {
res.send('Hello')
}
```
#### Bug not fixed
One EDGE case is not fixed. It occurs if you switch between edge and
server runtime several times without changing the content of the file:
Edge runtime
```js
export const config = {
runtime: 'experimental-edge',
}
export default () => new Response('Hello')
```
Change it to a server runtime
```js
export default function (req, res) {
res.send('Hello')
}
```
Change back to edge runtime, the content of the file is the same as the
first time we compiled the edge runtime version.
```js
export const config = {
runtime: 'experimental-edge',
}
export default () => new Response('Hello')
```
The reason is that both the edge and server compiler emits to the same
file (/.next/server/pages/api/hello.js) which makes this check fail in
webpack:
https://github.com/webpack/webpack/blob/main/lib/Compiler.js#L849-L861
Possible solution is to use different output folders for edge and server

Currently the DEV server can't recover if you export an invalid runtime
config. It ends up in a state where it stops to work but nothing is
printed to the terminal.
It now prints an error but keeps working. When building it should crash,
there's an existing test for that
https://github.com/vercel/next.js/blob/canary/test/production/exported-runtimes-value-validation/index.test.ts#L5-L17
#### Reproduce
```tsx
export default function Page() {
return <p>hello world</p>
}
export const config = {
runtime: 'something-odd',
}
```
Follow-up to #37551
Implements prefetching for the new router.
There are multiple behaviors related to prefetching so I've split them out for each case. The list below each case is what's prefetched:
Reference:
- Checkmark checked → it's implemented.
- RSC Payload → Rendered server components.
- Router state → Patch for the router history state.
- Preloads for client component entry → This will be handled in a follow-up PR.
- No `loading.js` static case → Will be handled in a follow-up PR.
---
- `prefetch={true}` (default, same as current router, links in viewport are prefetched)
- [x] Static all the way down the component tree
- [x] RSC payload
- [x] Router state
- [ ] preloads for the client component entry
- [x] Not static all the way down the component tree
- [x] With `loading.js`
- [x] RSC payload up until the loading below the common layout
- [x] router state
- [ ] preloads for the client component entry
- [x] No `loading.js` (This case can be static files to make sure it’s fast)
- [x] router state
- [ ] preloads for the client component entry
- `prefetch={false}`
- [x] always do an optimistic navigation. We already have this implemented where it tries to figure out the router state based on the provided url. That result might be wrong but the router will automatically figure out that
---
In the first implementation there is a distinction between `hard` and `soft` navigation. With the addition of prefetching you no longer have to add a `soft` prop to `next/link` in order to leverage the `soft` case.
A heuristic has been added that automatically prefers `soft` navigation except when navigating between mismatching dynamic parameters.
An example:
- `app/[userOrTeam]/dashboard/page.js` and `app/[userOrTeam]/dashboard/settings/page.js`
- `/tim/dashboard` → `/tim/dashboard/settings` = Soft navigation
- `/tim/dashboard` → `/vercel/dashboard` = Hard navigation
- `/vercel/dashboard` → `/vercel/dashboard/settings` = Soft navigation
- `/vercel/dashboard/settings` -> `/tim/dashboard` = Hard navigation
---
While adding these new heuristics some of the tests started failing and I found some state bugs in `router.reload()` which have been fixed. An example being when you push to `/dashboard` while on `/` in the same transition it would navigate to `/`, it also wouldn't push a new history entry. Both of these cases are now fixed:
```
React.startTransition(() => {
router.push('/dashboard')
router.reload()
})
```
---
While debugging the various changes I ended up debugging and manually diffing the cache and router state quite often and was looking at a way to automate this. `useReducer` is quite similar to Redux so I was wondering if Redux Devtools could be used in order to debug the various actions as it has diffing built-in. It took a bit of time to figure out the connection mechanism but in the end I figured out how to connect `useReducer`, a new hook `useReducerWithReduxDevtools` has been added, we'll probably want to put this behind a compile-time flag when the new router is marked stable but until then it's useful to have it enabled by default (only when you have Redux Devtools installed ofcourse).
> ⚠️ Redux Devtools is only connected to take incoming actions / state. Time travel and other features are not supported because the state sent to the devtools is normalized to allow diffing the maps, you can't move backward based on that state so applying the state is not connected.
Example of the integration:
<img width="1912" alt="Screen Shot 2022-09-02 at 10 00 40" src="https://user-images.githubusercontent.com/6324199/188637303-ad8d6a81-15e5-4b65-875b-1c4f93df4e44.png">
This PR implements the logic to make next-app-loader able to match multiple routes.
The app loader is refactored to construct the tree recursively instead of within a loop, as there could be multiple branches. Similarly, when entering a new layout level or branch, we resolve both the slot name (defaults to `"children"`) and the segment.
In order to make that work, the loader has to know all matched app paths. This is passed in as the `appPaths` loader option, which is gathered when creating the entrypoint.

## Feature
As the title, support `has` match, `local` that works the same with the `rewrites` and `redirects` of next.config.js on middleware config. With this PR, you can write the config like the following:
```js
export const config = {
matcher: [
"/foo",
{ source: "/bar" },
{
source: "/baz",
has: [
{
type: 'header',
key: 'x-my-header',
value: 'my-value',
}
]
},
{
source: "/en/asdf",
locale: false,
},
]
}
```

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
