When there're only one edge route in `pages/` and one in `app/`, the virtual client entry is split into pages chunks which is not expected.
We should only create client virtual entries for `app/`, not `pages/`, now we skip the `pages/` entries for client entry now

Reported by @hanneslund, when a CSS modules file gets imported in server
components, during `collectClientComponentsAndCSSForDependency` in our
client entry plugin it will always be collected no matter it is used or
not. Due to the restriction that we have to collect these imports to
create the client entry, it has to run in the `finishMake` compiler
phase and at that time, module optimization hasn't started yet.
To fix that issue, we run another pass in `afterOptimizeModules` just to
collect CSS imports for the server style manifest and we can filter out
unused modules there.

We observed this bug when using `.tsx` as the extension (currently the
condition only matches `.m?js`). Besides that, `react/jsx-runtime`
shouldn't be external too because it has React imported.

I am doing some work re: bundle size so I'm spending a lot of time looking at the bundles we generate. This debug options basically deactives mangling and beautifies the output whilst keeping the dead code elimination from Terser which is helpful for me to check what I'm removing.
this is what the output is like with it.

Re-do of https://github.com/vercel/next.js/pull/40251
Edge SSR'd routes cold boot performances are proportional to the
executed code size.
In order to improve it, we are trying to optimize for the bundle size of
a packed Edge SSR route.
This PR adds ESM compilation targets for all Next.js dist packages and
use them to bundle Edge SSR'd route.
This allows us to leverage the better tree shaking/DCE for ESM modules
in webpack in order to decrease the overall bundle size.
This PR also enables minifying Edge SSR routes. Since we don't control
which minifier might be used later (if any), it's best if we provide an
already optimised bundle.

This is a 10ms cold boot win per my benchmarking script, which I'll put

When fetching the middleware rewrite information via `_next/data` for a static page that is not a `fallback` we can use a `HEAD` request instead of a `GET` request which provides the necessary header information and saves some bandwidth by avoiding sending back the data that is already present in the page.

This PR adds a new `experimental.enableUndici` option to let the
developer switch from `next-fetch` to `undici` as the underlying
polyfill for `fetch` in Node.js.
In the current implementation, Next.js makes sure that `fetch` is always
available by using `node-fetch`. However, we do not polyfill in Node.js
18+, since those versions come with their own `fetch` implementation
already, built-in.
Node.js 18+ uses `undici` under the hood, so letting the developer use
`undici` earlier could make the migration easier later on.
Eventually, we hope to be able to stop polyfilling `fetch` in an
upcoming major version of Next.js, shipping less code.

We currently resolve the `react-server` condition correctly inside
`externals` for the server layer, however that will cause the resolved
path to be external (as it is called "externals").
So we need a way to hook into the module resolution process to force it
to use the `react-server` condition **when it's on the server layer**.
The `resolve` option doesn't give us that ability, and the solution in
this PR is to leverage `normalModuleFactory`'s resolve hook to override
the resolve options before actually resolving it. And there we can have
the `contextInfo`.
One thing left out is bundling for the edge server, we need to add tests
and sort that out carefully.

### 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.

When navigating from app to pages, we do a flight render on the server
to generate the redirected path. However due to our new bundling
strategy we can't use the bundled `ComponentMod.renderToReadableStream`
because the component is now a regular component, not a RSC. In that
case we have to import the unbundled flight server.

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

Adds `@next/font/local` font loader. Similar to `@next/font/google` but
used to host locally downloaded font files.
In the server layer, we used to alias `react` to the resolved path e.g. `/next.js/node_modules/.pnpm/react@0.0.0-experimental-e6a062bd2-20220913/node_modules/react`, but it turns out that webpack's enhanced resolver can't handle it correctly together with conditions, and the final resolved path is `/next.js/node_modules/.pnpm/react@0.0.0-experimental-e6a062bd2-20220913/node_modules/react/index.js`. If we change the alias to `react: 'react-exp'` then it correctly resolves to `/next.js/node_modules/.pnpm/react@0.0.0-experimental-e6a062bd2-20220913/node_modules/react/react.shared-subset.js`.

Fixes#40463
Could use some help figuring out where to add a test! I looked around
and found
[`jest-next-swc.test.ts`](https://github.com/vercel/next.js/blob/canary/test/unit/jest-next-swc.test.ts),
but I don't think I can use that to test this fix. Anyways, from my
local testing this PR seems to fix the issue.

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.

For app edge SSR, we don't need any internal pages for it since it's
handled by app-renderer. This results around reducing 20KB from app edge
SSR
# Changes
* Strip those internal pages modules when it's in app edge SSR
* Minimize edge SSR chunk to see the tree-shake result
* Add bundle analyzer with switcher in stats-app for testing. Using
`TEST_ANAYLYSE=1` to build stats-app for testing

Adds `@next/font` package.
`scripts/update-google-fonts.js` generates functions and metadata for
all available google fonts. The metadata is used in `loader.ts` to
validate font options (from #40221). It then fetches the CSS from google
fonts, downloads the font files and emits them as static assets.
The actual integration with `packages/next` and integration tests
depends on #40221, will follow up with new PR.

`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.

Leverages `AsyncLocalStorage` when available for handling static generation context and falls back to requiring render to be isolated when `AsyncLocalStorage` is not available.
Note: most changes are spacing so toggling to ignore spacing may make reviewing easier
## Problem
Currently the Next.js infer utility (`InferGetServerSidePropsType` and
`InferGetStaticPropsType`) types can lead to a wrong inferred types
(`never`). This happens if these functions return something different
than: `{props: {}}`.
**Example:** `getServerSideProps`
```typescript
export async function getServerSideProps({ query }: GetServerSidePropsContext) {
if (query.foo) {
return {
notFound: true,
}
}
return {
props: {
foo: "bar"
},
}
}
type PageProps = InferGetServerSidePropsType<typeof getServerSideProps>
// => type PageProps = never
```
**Example:** `getStaticProps`
```typescript
import type { InferGetStaticPropsType, GetStaticPropsContext } from 'next'
export async function getStaticProps(context: GetStaticPropsContext) {
if (context.params?.bar) {
return {
notFound: true,
}
}
return {
props: {
foo: 'bar',
},
}
}
type PageProps = InferGetStaticPropsType<typeof getStaticProps>
// => type PageProps = never
```
This is because the first infer condition of the utility type is not
satified leading to a never result.
```typescript
export type InferGetServerSidePropsType<T> = T extends GetServerSideProps<
infer P, // <- NOT SATISFIED
any
>
? P
: T extends (
context?: GetServerSidePropsContext<any>
) => Promise<GetServerSidePropsResult<infer P>>
? P
: never // <- NOT SATISFIED
```
## Solution
I have experimented with different solutions ending with a much simpler
type, that is faster to execute, easier to read and universally usable
for both prop variations.
```typescript
/**
* Flow:
* - Make sure getStaticProps is a function
* - Get its return type
* - Extract the one that contains {props: any}
* - Return the props
*/
export type InferGetStaticPropsType<T extends (args: any) => any> = Extract<
Awaited<ReturnType<T>>,
{ props: any }
>['props']
```

- [x] Type tests added
## Future thoughts
Since `InferGetStaticPropsType` and `InferGetServerSidePropsType` are
now the same, it's api could be merged into one utility type (e.g:
InferNextProps). I recommend doing this in a different PR.
## Additional info
I have tested this approach using the following [external
package](https://www.npmjs.com/package/infer-next-props-type)
(@timneutkens sorry for the late PR). Since about 12 Month I haven't
received any negative feedback (issues) regarding this approach.

We have heuristic checks in the SWC transform to make sure you are not
using client-only APIs such as `useState` inside the Server Components
graph. However inside our server graph compilation we also have to
import the framework and renderer itself (not just the component), and
some utility files import these client APIs (because they can be shared
by the SSR or client code). Hence we have errors like
https://github.com/vercel/next.js/actions/runs/3083270196/jobs/4984135491.
To manually opt-out these errors, you can do `import React from 'react'`
and use these APIs via `React.useState`.

Tree share the `typeof window` conditions in styled-jsx for edge runtime. Let swc loader go through the styled-jsx assets under node_modules, applying the optimization as well
`test-app/server/edge-ssr.js` -155B
As per @sebmarkbage's suggestion, this PR refines the error message to
be more readable and friendly:
```
error - ./components/qux.js
You're importing a component that needs useEffect. It only works in a Client Component but none of its parents are marked with "client", so they're Server Components by default.
,----
5 | import { useEffect } from 'react'
: ^^^^^^^^^
`----
Maybe one of these should be marked as a "client" entry:
./components/qux.js
./components/baz.js
./components/bar.js
./app/dashboard/index/page.js
```
It's more ideal to put error codes inside the SWC transform and format
it in the Next.js logging layer. A future improvement is to tweak the
message a bit more for these specific cases:
- [ ] The error already happens inside an entry point (page or layout),
so itself should have "client" added (or removed), not it parents.
- [ ] When importing `"server-only"` inside a client component, we can
directly hint to the user which module in the import chain is marked
with `"client"`.

We used to do an extra pass of SWR `parse` and loop over the AST inside
JavaScript to check if `getServerSideProps` or `getStaticProps` is used
in a client page or layout. Instead this can be done in the same
`react_server_components` SWC transform now.

When the error comes from the RSC transform in SWC, we want to enforce the verbose mode because the module trace can be critical here. An example:
<img width="635" alt="CleanShot 2022-09-18 at 12 37 02@2x" src="https://user-images.githubusercontent.com/3676859/190898135-7b258ae1-64e4-4c7b-b4d3-b2e9d2ee0245.png">
Also in this PR I changed `trace.originName` to `trace.moduleName` in the output as the former can contain loader information and options:
```
Import trace for requested module:
./app/dashboard/index/page.js

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.

Bump the version of `react-server-dom-webpack` and use `experimental_use` to unwrap the promise to access RSC payload instead of using `readRoot`. `readRoot` is removed from the response type.
This masks flight parameters from middleware so it doesn't interfere with RSC or routing.

Another step toward fixing #40025.
Multiple `next/script` components with the same `src` may exist in the
Next.js app. So the `loadScript` function will always attach the
`onLoad` handler to the `loadingPromise` every time it executes.
However, with strict mode (or wrapped inside the `<OffScreen />`
component), the `useEffect` could execute more than once for the same
`next/script` component, thus the `loadScript` for each `next/script`
component could execute more than once (and `onLoad` to be attached more
than once), results in `onLoad` fires more than once.
The PR makes sure that for every `next/script` component mounted, the
`loadScript` will always be executed only once for each of them.
The corresponding `onload fires correctly` integration test case is also
updated to run in dev mode.

### 📖 What's in there?
Dynamic code evaluation (`eval()`, `new Function()`, ...) is not
supported on the edge runtime, hence why we fail the build when
detecting such statement in the middleware or `experimental-edge` routes
at build time.
However, there could be false positives, which static analysis and
tree-shaking can not exclude:
- `qs` through these dependencies (get-intrinsic:
[source](https://github.com/ljharb/get-intrinsic/blob/main/index.js#L12))
- `function-bind`
([source](https://github.com/Raynos/function-bind/blob/master/implementation.js#L42))
- `has`
([source](https://github.com/tarruda/has/blob/master/src/index.js#L5))
This PR leverages the existing `config` export to let user allow some of
their files.
it’s meant for allowing users to import 3rd party modules who embed
dynamic code evaluation, but do not use it (because or code paths), and
can't be tree-shaked.
By default, it’s keeping the existing behavior: warn in dev, fails to
build.
If users allow dynamic code, and that code is reached at runtime, their
app stills breaks.
### 🧪 How to test?
- (existing) integration tests for disallowing dynamic code evaluation:
`pnpm testheadless --testPathPattern=runtime-dynamic`
- (new) integration tests for allowing dynamic code evaluation: `pnpm
testheadless --testPathPattern=runtime-configurable`
- (amended) production tests for validating the new configuration keys:
`pnpm testheadless --testPathPattern=config-validations`
To try it live, you could have an application such as:
```js
// lib/index.js
/* eslint-disable no-eval */
export function hasUnusedDynamic() {
if ((() => false)()) {
eval('100')
}
}
export function hasDynamic() {
eval('100')
}
// pages/index.jsx
export default function Page({ edgeRoute }) {
return <p>{edgeRoute}</p>
}
export const getServerSideProps = async (req) => {
const res = await fetch(`http://localhost:3000/api/route`)
const data = await res.json()
return { props: { edgeRoute: data.ok ? `Hi from the edge route` : '' } }
}
// pages/api/route.js
import { hasDynamic } from '../../lib'
export default async function handle() {
hasDynamic()
return Response.json({ ok: true })
}
export const config = {
runtime: 'experimental-edge' ,
allowDynamic: '/lib/**'
}
```
Playing with `config.allowDynamic`, you should be able to:
- build the app even if it uses `eval()` (it will obviously fail at
runtime)
- build the app that _imports but does not use_ `eval()`
- run the app in dev, even if it uses `eval()` with no warning
### 🆙 Notes to reviewers
Before adding documentation and telemetry, I'd like to collect comments
on a couple of points:
- the overall design for this feature: is a list of globs useful and
easy enough?
- should the globs be relative to the application root (current
implementation) to to the edge route/middleware file?
- (especially to @sokra) is the implementation idiomatic enough? I've
leverage loaders to read the _entry point_ configuration once, then the
ModuleGraph to get it back during the parsing phase. I couldn't re-use
the existing `getExtractMetadata()` facility since it's happening late
after the parsing.
- there's a glitch with `import { ServerRuntime } from '../../types'` in
`get-page-static-info.ts`
([here](https://github.com/vercel/next.js/pull/39539/files#diff-cb7ac6392c3dd707c5edab159c3144ec114eafea92dad5d98f4eedfc612174d2L12)).
I had to use `next/types` because it was failing during lint. Any clue
why?

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.

Added missing trace for `client-full-reload` event in hot reloader. Full
reload tests moved to hmr, think they make more sense there than on
their own.
The PR fixes#40388.
Currently, `next/dynamic` will try to provide a default `loading` to the
`loadableOptions` even when `suspense` is enabled, thus triggering the
incorrect warning. The PR fixes that. The corresponding integration test
case is also updated.

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.
When a client module is imported by both a module from an `app` entry and a module from `pages` entry, it is possible that it is included in the `pages` chunk eventually. The current check makes the manifest incomplete in that case.

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',
}
```

Fixes#36251
This PR allows you to resize a statically imported image using only `width` or only `height`. For example:
```jsx
import img from './img.jpg'
<Image src={img} width="200" />
```
Previously, you had to specify both or else the image aspect ratio would not be preserved.

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.

Fixes: https://github.com/vercel/next.js/issues/39853
Check `pagesDir` to bypass empty pages folder when appDir is enabled
* Output empty loadable manifest for now if there's no `pagesDir`
* No custom aliases with all page extensions for `/_app`, `_document` if pagesDir is empty, only keep the built-in ones
* Check pagesDir in build/dev-server/eslint
* Type safe: change arguments of some APIs from optional to required, so that we won't mess up with default arguments
The PR is the first step toward fixing #40025. The PR makes the `script-loader` integration test run on both dev and production modes.
Some existing test cases are skipped in dev mode because corresponding features are not strict mode resilient and thus will fail. They will be included in dev mode tests in the future.
The PR also merges some duplicated logic in `next/script`, and adds a detailed comment about how `onReady` works.
In the next PR, I will try to fix `onLoad` being called more than once under strict mode.
