This adapts the new client hooks of `usePathname`, `useSearchParams`,
and `useRouter` to work within the `pages/` directory to aid users
attempting to migrate shared components over to the `app/` directory.
> **Exception:**
> When the pages router is not ready, `useSearchParams` will return an
empty `URLSearchParams`. This mirrors the behavior seen in the `pages/`
directory today in that `router.query` is not available until the client
hydrates.
This also adds a new option for `useRouter` to bring it line with the
correct typings with the app directory. By default, calling
`useRouter()` will return the type `NextRouter | null` to represent what
you get when you call it from a component originating from the app
directory. If you want to instead force it to return `NextRouter` as it
does today, you can pass a boolean into the `useRouter` call as such:
```ts
const router = useRouter() // typeof router === NextRouter | null
const router = useRouter(true) // typeof router === NextRouter
```
This change is designed to ease the incremental adoption of app.
Fixes typo and makes sure both loaders always have a default value.

As per
https://github.com/vercel/next.js/issues/41951#issuecomment-1294199692,
this PR improves the TS plugin error message when a non-literal
configuration is used:

Also a bug is fixed so string template literals (``const revalidate =
`auto`;``) will no longer result in an error.

Removing the `hasReactRoot` condition and `__NEXT_REACT_ROOT` env var since next 13 requires latest react 18 to be installed, all the react 17 (non concurrent mode) compatible code can be dropped now.
Follows `reactStrictMode`. Still recommended to have it enabled (which is the default for new apps). This will become increasingly more important as other features on top of concurrent rendering are implemented.

We currently only fallback to the global `runtime` option if the page
actually **needs** a runtime (not statically optimizable). That happens
for SSG (ISR) and SSR for pages/. But for app/, we will always need a
`runtime` to render server components.
Also in this PR, I improved the tests to actually **test** the runtime
to ensure it has `globalThis.EdgeRuntime` so it's not running in the
Node.js runtime
([ref](https://edge-runtime.vercel.app/features/available-apis#addressing-the-runtime)).

`next/dist/shared` will not be bundled, but we shouldn't apply it to rsc

Right now the SSG condition is determined _only_ based on
`supportsDynamicHTML`. However that `supportsDynamicHTML` flag can be
affected by bots too.
Here we exclude the `isBot` condition from the SSG flag, and set proper
status and meta tags for static HTML requests (and/or 404 cases).

When esm package that depending on react is used between `pages/` and
`app/`, it's loading the user installed react through esm loader which
doesn't go through require hook, so we cannot intercept it with
require-hook.
Disable esm resolving when `appDir` is enabled for now, prefering to
pick the cjs bundle so that react import is intercepted by require hook
and pointing to the built-in react

Creates a root layout if it is missing in DEV when building the page in
`next-app-loader`. If the page is in a route group, the layout will be
created there. Otherwise it will create a layout directly under `/app`.

Bundle the ssr client layer for RSC, this solves the problem when
there's an esm package is using on client components, but esm imports
the installed react instead of the built-in react version since esm
imports is not intercepted by require hook.
After bundling the ssr client layer and treating react as externals, now
react compiles as cjs externals and could be intercepted by require
hook, other code are bundled together which can also get optimized.

This PR updates `@types/node` to `14.14.31`. The most important type is
that `ParsedUrlQuery` can hold `undefined` so we are updating the code
here to explicitly handle those cases. Aside from it we are adding a
global definition taken from NodeJS for `AsyncLocalStorage` that we
export in `server.d.ts`
Adds default config if @next/font is a dependency. Warns instead of
errors when subsets is missing.

This PR adds a new configure property, `images.loaderFile` that allow
you to define a path to a file with an exported image loader function.
This is useful when migrating from `next/legacy/image` to `next/image`
because it lets you configure the loader for every instance of
`next/image` once, similar to the legacy "built-in loaders".
## 📖 Feature
Adds `AsyncLocalStorage` as a global variable to any edge function (middleware, Edge API routes).
Falls back to Node.js' implementation.
## 🧪 How to test
1. `pnpm build`
2. `pnpm testheadless --testPathPattern async-local`
Remove head as required in root layout.

I'm investigating the runtime perf of the node server and this was one of the hot spot I stumbled upon.
This diff:
- refactors getPagePath to not throw when it doesn't find a path: this function is used to check if a path exists, we don't want that kind of overhead there
- adds a LRU cache to cache the result of the evaluation

This PR adds a feature in middleware to add, modify, or delete request headers. This feature is quite useful to pass data from middleware to Serverless/Edge API routes.
### Questions for Reviewers
- Should we deny modifying standard request headers like `Transfer-Encoding`?
- Should we throw an error if the header is too large? Real-world HTTP servers will accept up to only 8KB - 32KB.
### New APIs
Adds a new option `request.headers` to the `MiddlewareResponseInit` parameter in `NextResponse.next()` and `NextResponse.rewrite()`. It's a [`Header`](https://developer.mozilla.org/en-US/docs/Web/API/Headers) object holding *all* request headers. Specifically:
```ts
interface MiddlewareResponseInit extends ResponseInit {
request?: {
headers?: Headers
}
}
```
### Example
```ts
// pages/api/hello.ts
export default (req, res) => {
const valueFromMiddleware = req.headers['x-hello-from-middleware']
return res.send(valueFromMiddleware)
}
// middleware.ts
import { NextRequest, NextResponse } from 'next/server'
export default function middleware(request: NextRequest) {
// Clone request headers
const headers = new Headers(request.headers);
// Add a new request header
headers.set('x-hello-from-middleware', 'foo');
// Delete a request header from the client
headers.delete('x-from-client');
const resp = NextResponse.next({
// New option `request.headers` which accepts a Headers object
// overrides request headers with the specified new ones.
request: {
headers
}
});
// You can still set *response* headers to the client, as before.
resp.headers.set('x-hello-client', 'bar');
return resp;
}
```
### New middleware headers
- `x-middleware-override-headers`: A comma separated list of *all* request header names. Headers not listed will be deleted.
- `x-middleware-request-<name>`: A new value for the header `<name>`.

This PR implements the TypeScript plugin (only applied to the app directory), and it will be automatically added to tsconfig.json when running the CLI. Due to how TS plugins work (a package name is required to specify), hence we can't use a subpath import like `next/typescript` for the plugin. To avoid installing a separate dependency, here I propose to reuse the `next` package: if the default export is called with the TypeScript option, we can say it's being used as a plugin. There is also environment variables we can check here, however it's specifically for VS Code (`VSCODE_CLI=1`) where this plugin should be working with other editors too.
