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.
Previously we use `path.join(compiler.context, chunk.name)` as the entry
name, which isn't always the case especially when there is the `src`
folder. This PR fixes that by using `appDir`.

fixes https://github.com/vercel/next.js/issues/42006
this issue occurred because images with `data url` src start with `blob`
and `data` will be mark as `unoptimized`, then its `sizes` will be
assigned with `undefined`.
I just skip the check for `data url` images, if there is any better
solution, we can have a discuss here.

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)).

By default the edge page entry is in the client layer because it bundles Next.js. It's a virtual loader (edge-ssr-loader) but that makes the SWC loader think the page's source is a client component.
We use the resource query `__edge_ssr_entry__` to convert it to the server layer but we need to add that condition to the SWC loader too.

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`.
Breaks the build if a page is found that's missing a root layout.

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.

For `next/legacy/image`, the `data-nimg` has the `layout` prop value.
Since `next/image` doesn't have a `layout` prop, we can use `fill` when
the fill prop is used or fallback to `1`.
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 support for:
- outputting what kind of build we did for routes in the app folder:
SSR, SSG, static
- adds the list of SSG'd routes
- adds JS size for app routes

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
Results:

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.

This PR fixes two bugs:
- Fixes#40419
- Fixes#41393
The first is when the aspect ratio of the `width` and `height` does not
match the aspect ratio of the `blurDataURL` provided. This can result in
artifacts around the edges. The solution is to add
`preserveAspectRatio="none"`.
The second is when there is no `width` or `height` provided (which is
normal when using `fill`) so the viewBox was undefined. This can also
cause artifacts around the edges. The solution is to change the blur
technique from gaussian to css filter, similar to `next/legacy/image`.
Note: css blur might be [slower in
firefox](https://bugzilla.mozilla.org/show_bug.cgi?id=925025) which is
why we'll only use it for this corner case.
Fixes#41476, ref #40679

Add failing test for the back button download bug. Created it as a new
app given that adding it to the existing `app` suite did not reproduce
the issue for some reason.
The underlying reason is that we need to add `Vary: __rsc__,
__next_router_prefetch__` to ensure Chrome does not cache the response
and serve it on back button.
The download was caused by the `application/octet-stream` content type,
but that was just a consequence of serving the wrong response.

Consider the following middleware which redirects to
`/path/to#fragment`.
```ts
import { NextResponse } from 'next/server';
export async function middleware(request) {
const url = new URL('/path/to#fragment', request.url);
return NextResponse.redirect(url);
}
```
However, it actually redirects to `/path/to`, namely it discards the
fragment part in the destination URL `#fragment`. This is because
`NextURL.toString()` does not append that part. This PR fixes the bug.

It’s possible that global CSS imports, that come from node_modules, are
marked as side effect free because of possible `sideEffects: false` in
the external package's package.json. In that case, we still need to
handle global CSS imports as side effects on the server because we need
to collect them and avoid tree-shaking for these modules.
You can take a look at the test case to see what exactly happened.

The PR continues from #41392.
In #41392 the `dev ? cache-busting : empty` is executed per stylesheet instead of per page rendering. Since rendering link tags would be a hot path at the server, it might have accidentally introduced a performance overhead. The PR fixes that.
Note, this change also makes `Date.now()` only execute once instead of per stylesheets, however, this will most likely not cause any issues.
Similar to #40872 `useSearchParams` now returns a `URLSearchParams` instance instead of a plain object.

Since we have already bundled dependencies for server layer, so the

This ensures we don't re-use edge workers locally as they are meant to

This PR introduces breaking changes by renaming components.
- Rename `next/image` to `next/legacy/image`
- Rename `next/future/image` to `next/image`
The diff is very confusing because both components are very similar so git got confused.
In this PR, I'm inlining the require for some of the modules that I
noticed take a bit of time to evaluate on a cold boot and are not needed
most of the time.
With this, it's an extra ~15ms win on cold boots (tested locally) and we
are now at around 68ms (started from 110+).

The `ReadOnlyHeaders` class extends the `Headers` class that is provided
via a polyfill. This incurs some costs the first time it's created
because we need to load that polyfill. This saves approximately 10ms on
my machine on a cold request.
This is only useful when a user does not access headers during the
request of course and when the runtime does not support fetch naitvely.

The PR continues from #41164.
`next/script` with `beforeInteractive` should not block the hydration,
**but the `polyfill-nomodule` *should* block the hydration** (and should
be loaded before other scripts), as `polyfill-nomodule` includes
multiple polyfills to even execute `main-app.[hash].js` properly on old
browsers (`Array.prototype.includes`, `String.prototype.startsWith`,
etc.).
Without `polyfill-nomodule` being loaded first, the entire
bootstrap/hydration process might not even work on old browsers. So it
should not be loaded through `__next_s`.

The way we currently track server CSS imports is to collect CSS files that each **module** depends on. This happens on the module graph level which is a global thing and cannot be tree-shaken properly (check the enabled test for more details).
In this PR we collect another information, of CSS files that each **entrypoint** depends on. This is the CSS list after tree-shaken on the entry level. By intersecting these CSS imports with the module-level CSS imports, we can get the final used CSS imports for each _layout_.

This adds two codemods for `next/image`.
The first codemod a safe solution to upgrade from 12 to 13 by swapping
to `next/legacy/image`.
The second codemod is an experimental solution that attempts to automate
the [migration

## Context
I'm investigating cold boot perf
## This PR
Did some manual analysis on next cold boot for the "regular" node target
and found out that we are spending a good 10ms evaluating the edge
runtime module when we shouldn't be in most cases.
This is a quick fix to only load it when actually required.
## Test plan
I have a simple script which I'll push in a separate PR to measure the
cold boot.
Results:
before:
<img width="230" alt="image"
src="https://user-images.githubusercontent.com/11064311/195073994-c3d28961-5d22-401f-a4b0-026c791ff2bd.png">

it appears to be a 10~15ms win on cold boot
## Following up
We probably want a separate NextMinimalServer type of build?

Fixes#41258
When we detect `type: "module"` in `package.json`:
~1. generate `server.mjs`~ Not necessary when `type: "module"` is set.
2. use `import` instead of `require`
3. replace `__dirname` with [ESM compatible
alternative](https://blog.logrocket.com/alternatives-dirname-node-js-es-modules/)
In this PR, I also moved some tests (those using `output: "standalone"`)
to a new `test/production/standalone-mode` directory for easier
discoverability in the future.
Run the related test with `pnpm test

In Jest, we were mocking the `next/image` imports with a width and
height of `24`. If the developer set `placeholder="blur"` on their
images though, this triggered the warning:
> Image with src "/img.jpg" is smaller than 40x40. Consider removing the
"placeholder='blur'" property to improve performance.
Since we cannot reliably hide this warning without knowing the actual
image dimensions, and we also provide a `blurDataURL` by default, we
should increase the mock image size to suppress the warning.
Note that using `moduleNameMapper` in `jest.config.js`, the developer
can already tweak the mock behavior:

This updates to skip the data request done during query hydration when
middleware is present as it was mainly to gather query params from any
potential rewrites in middleware although this is usually not needed for
static pages and the context can be gathered in different ways on the
client.

When using `@next/font/local` we can't have pre calculated metrics for the font. This PR uses fontkit to read metadata about the imported local font in order to generate a fallback.
Also removes some props from the api that's better done automatically in the future.

This PR ensures that for the app directory, `beforeInteractive`, `afterInteractive` and `lazyOnload` scripts via `next/script` are properly supported.
For both `beforeInteractive` and `afterInteractive` scripts, a preload link tag needs to be injected by Float. For `beforeInteractive` scripts and Next.js' polyfills, they need to be manually executed in order before starting the Next.js' runtime, without blocking the downloading of HTML and other scripts.
This PR doesn't include the `worker` type of scripts yet.
Note: in this PR I changed the inlined flight data `__next_s` to `__next_f`, and use `__next_s` for scripts data, because I can't find a better name for `next/script` that is also short at the same time.

Kudos @dferber90 who found this issue. Added a test and handled it gracefully for now. Keep in mind the behavior can't be 1-1 so it takes the `as` as the `href` value given that masking of parameters in this way is no longer supported, that will be superseded by parallel routes / route interception.

It seems that #38867 made `AppProps` always require the `pageProps`
object shape to be passed as a generic since the default `{}` will throw
a TS error if you try accessing any property:

Technically, it would be more correct since accessing `pageProps`
properties would otherwise be unsafe, but this seems to break the

## 🐛 What's in there?
`foo instanceof Function` is wrongly considered as Dynamic code evaluation by our static analyzer.
This PR fixes it.
- [ ] Related issues linked using `fixes #number`
- [x] Integration tests added

## 🧪 How to reproduce?
1. Create a simple repro in `examples` folder:
```js
// examples/instance-of-function/pages/index.js
export default function Home() {
return <h1>home</h1>
}
// examples/instance-of-function/middleware.js
import { NextResponse } from 'next/server'
export default async function handler() {
console.log('is arrow a function?', (() => {}) instanceof Function)
return NextResponse.next()
}
```
1. build with next `pnpm next build examples/instance-of-function`
> the build fails
1. rebuild next to include PR's fix `pnpm build`
1. build with new next `pnpm next build examples/instance-of-function`
> the build works
## 📔 Notes to reviewers
`hooks.expression.for(`${prefix}Function`).tap(NAME, handleExpression)` is actually legacy code from the original implementation. It's used when finding `Function` regardless of how it is used. We only want to find `new Function()` or `Function()`, which `hooks.calls` and `hooks.new` are covering.
`eval instanceof Function` is perfectly legit code on the edge, despite its uselessness :lol-think:
Because we got multiple people asking "how do I relax this error when my code contains unreachable dynamic code evaluation", I've copy-pasted details about `config.unstable_allowDynamic` into the error page. Because users do not always click links :blob_shrug:

Finds the font files connected to font loader modules and adds them to
the font loader manifest. They're then collected and rendered similarly
to CSS links in app-render.
The behaviour of edge-function-runtime in the case of an error was not
identical to the edge-runtime.
If a type other than "Uint8Array" is written to the Response stream a
unhandledreject is raised and logged.
The current implementations(nodejs) accepts also Buffers and Strings
which causes that a Application
Developer things our stream implementation is broken if it is executed
as worker.
We introduced a helper function to consume the response stream and write
the "Uint8Array" stream chunks
to the server implementation. Due to the complication that the error
side effect is emitted via the unhandledrejection
handler it is almost impossible to test --- jest does not allow testing
of the unhandlerejections.
We tested extendsiveliy the helper in the edge-runtime so that this PR
integrates just the consuming function.

Since `next/dynamic` has client hooks that not compatible with server
components, and app renderer doesn't provide context (such as
`LoadableContext`) for it to use. Previously we provided a simple
replacement using `React.lazy` for `next/dynamic` if you want to use it
in appDir.
This PR always alias it to the `React.lazy ` implementation for appDir
so that user won't need to worry about the dynamic options. They can
only use `dynamic()` without 2nd options arg
```js
import dynamic from 'next/dynamic'
const Dynamic = dynamic(() => import('./dynamic-component'))
```
Fixes an issue where `const […foo] = useState(0)` is improperly transformed into `const { 0: …foo } = useState(0)`.
The hook optimizer was useful when hooks first came out, primarily because browsers had never optimized array destructuring. But current browsers have, and the optimization doesn't help anymore.

We're supposed not to use css-in-js in server components since it will
increase the rsc response for navigation. Also adding `styledJsx` option
for next-swc for controlling styled-jsx transform.
Test case: using styled-jsx transform in server components will not be
transformed to `styled-jsx/style` imports.
- Add a failing test for navigating between many levels of dynamic routes
- Create router tree during prefetch action so that it can be reused across multiple urls
- Ensure segmentPath is correct when rendering a subtree. Previously it would generate a segmentPath that starts at the level it renders at which causes the layout-router fetchServerResponse to inject `refetch` at the wrong level.
- Fixed a case where Segment was compared using `===` which is no longer valid as dynamic parameters are expressed as arrays. Used `matchSegment` helper instead.

## Bug
Noticed the warning messages don't have spaces. Just adding spaces for better messaging.

This fixes the build failing due to attempting to read `edgeInfo` that
wasn't present from using the wrong key to look up the manifest entry.
Regression test added by enabling `experimental-edge` on a page that was
failing to be looked up.
Fixes:
```sh
TypeError: Cannot read properties of undefined (reading 'files')

This applies the experimental configs for testing and also fixes
`set-cookie` headers from middleware/edge functions being merged
unexpectedly.

Include the edge server changes that starting in app dir into server components changes. Most changes are merging condition `isAppPath && this.appDir` into `isAppPath`.

As discussed this updates our required minimum Node.js version to `v14` as `v12` is no longer being maintained. Since our targets for babel and swc already target the actively used Node.js version no change has been made there.
