This PR makes sure that the same polyfills are added in app dir for
browsers that match `nomodule`. Main difference from the polyfills in
pages is that the script tags here cannot have `defer` as all other
scripts will be async by default, and polyfills must be executed before
all of them.

Alias all existing imports from `next/dist/..` to `next/dist/esm` for edge compiler. So that we don't need checking for `process.env.NEXT_RUNTIME === 'edge'` or passing down `nextRuntime` to decide wether the esm or cjs asset to require
This will also fix the issue that some layouts hook are been included twice into the bundle with cjs and esm bundle in edge runtime, now only esm chunk will be bundled in server.
This caused unexpected full page reloads when viewing pages in `pages`. E.g. when navigating to `app`. Since `app` is the only place you can have server components now this is no longer needed.

When possible (`ReactRoot` enabled), we always use
`renderToReadableStream` to render the element to string and drop all
`renderToString` and `renderToStaticMarkup` usages. Since this is always
true for the Edge Runtime (which requires React 18+), so we can safely
eliminate the `./cjs/react-dom-server-legacy.browser.production.min.js`
module there
([ref](https://unpkg.com/browse/react-dom@18.2.0/server.browser.js)).
This reduces the gzipped bundle by 11kb (~9%). Let me know if there's
any concern or it's too hacky.

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.

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.

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
in a subsequent PR.

- ~~swap exported requires in `next/link` (and others) etc to point them

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.

Since React 18 returning `undefined` from components is allowed which renders to `undefined` in the RSC response so we need a separate prop to know if the loading boundary was provided.

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.

Currently, a developer building a website using Next.js could write this
code with no type errors:
```tsx
<Image
width="kangaroo"
height="100px"
quality="medium"
{...rest}
/>
```
This PR adds stricter type checking, which will catch this type of error
earlier.
Similarly, this PR adds stricter types for the `responseLimit`, to
ensure the types align to:

# Context
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
in a subsequent PR.

### 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
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.
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.

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

in a client page or layout. Instead this can be done in the same

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 fixes the WASM handling for edge during deploy as the sandbox

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.

Closes#40571
An earlier fix in #24481 did not consider the `/` case. The page path normalization method `normalizePagePath` turned `/` into `/index` and the route matching was skipped for the index route's non-existent HTML file.

Adds a new option to the current font optimization to enable
experimental font size adjust
The new `optimizeFonts` config will be
```
optimizeFonts: {
inlineFonts: true,
experimentalAdjustFallbacks: false,
},
```
To enable the feature, set `experimentalAdjustFallbacks: true`
`optimizeFonts: false` will disable the entire feature (including
inlining google font definition)

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)

#### 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',
}
```

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] 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:

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.

This PR updates a few features from experimental to stable status:
- `next/future/image` component
- `remotePatterns` configuration
- `unoptimized` configuration
This addresses a bug where invoking `next dev` or `next start` with `--port 0` would fall back to the default port of 3000 instead of binding to port 0 (which typically results in the operating system assigning a free port).
I couldn't find a straightforward way of adding a test for next-start. It looks like we could add a similar test as for dev, but would need to generate a built project to serve.
Manual test plan for `next start`:
```
$ ./packages/next/dist/bin/next start --port 0
ready - started server on 0.0.0.0:53508, url: http://localhost:53508
```

This PR removes `<noscript>` from `next/future/image` since it is no longer needed now that we use a svg blur placeholder (as opposed to css filter).
- Fixes #38621
- Closes#39736
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
We only use `if (child.type === Script)` on the server side to check the
element type, that's unnecessary because we can add a special flag for
that (`__nextScript` in this PR).
This reduces the server bundle by ~13kb if `next/script` is not imported
by the user.

Fixes#39993.
Before the PR:
- `next/script` component mount, `useEffect` for `onReady` executes
- The script's cacheKey is not added to `LoadCache`, skip `onReady`
- The second `useEffect` for `loadScript` executes
- The script's cacheKey is added to `LoadCache` even if it might not fully load yet
- Because of React's strict mode, `useEffect` for `onReady` executes again
- Since the script's cacheKey is in `LoadCache`, `onReady` is called (even when the script is not loaded yet)
- After the script is actually loaded, inside the `script.onload` event handler the `onReady` is called again
After the PR:
- `next/script` component mount, `useEffect` for `onReady` executes
- The script's cacheKey is not added to `LoadCache`, `useEffect` skips `onReady`
- The second `useEffect` for `loadScript` executes
- The script's cacheKey is added to `LoadCache` only if it is an inline script
- Because of React's strict mode, `useEffect` for `onReady` executes again
- The script is not yet loaded, its cacheKey is not in `LoadCache`, `useEffect` skips `onReady` again
- After the script is actually loaded, inside the `script.onload` event handler the `onReady` is finally called
In short, the PR resolves a race condition that only occurs under React strict mode (and makes the `next/script` component more concurrent rendering resilient).

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.

This fixes the prefetching handling when middleware is present as currently we are incorrectly triggering data requests for non-SSG pages to handle the case where a middleware rewrite is present and pointing to an SSG path. Since the majority use case won't be rewriting in middleware and this incurs a lot of potentially heavy requests to `getServerSideProps` paths this matches the prefetch handling when middleware isn't present and only prefetches the data route when we match an SSG path.

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.

This PR enables a path to loading wasm binding first for the few platforms we'll attempt to remove native binaries. As a first step, this change does not actually removes native bindings, but will try to load wasm binding first and use it if loading success.
It may take some time to actually remove native bindings, I expect we may need to fix few regressions from wasm bindings for some places like loading / installing itself for the platforms not being used widely, meanwhile native bindings can be used as a fallback.

We shouldn't be warning when no eslint config file is present as it's valid not to use eslint. The warning is still shown if an empty eslint config file is added as this gives intent to using eslint.

Fixes#39807.
When statically importing an image, the `width` and `height` will always be provided alongside the `src` by the Webpack. `next/image` will ignore `width` and `height` come from Webpack when `layout === 'fill'`, while `next/future/image` will not, hence the issue. The PR fixes that. The corresponding integration test cases are also added.

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.

This removes the usage of `Node12` from the `parsedValues` for `moduleResolution` as this caused false detection of `undefined` being a valid value when it was removed in TypeScript. This also copies over the test from https://github.com/vercel/next.js/pull/37302 to ensure we don't regress on this.

Closes: https://github.com/vercel/next.js/pull/37302
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.
Improve PR improves the error message on `next/future/image` when `objectFit` or `objectPosition` is provided and suggests using `style` instead. It also prints the stack trace so its clear where the error came from.
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 neither fixes a bug nor introduces a new feature. It just makes the current code be more clearer.
We track the `unobserve` method (to clear the side-effect) in a ref before this PR which is not required anymore:
- The `unobserve` method can only be created during the `useEffect`
- The `unobserve` method will be called during `useEffect` cleans up.
In short, the "life cycle" of the `unobserve` method now only lives inside the `useEffect`. So we can remove the usage of `useRef`.
The PR is similar to #39791.
Currently, `<Portal />` saves the container in a ref (with initial value as `null`). The update of the ref happens during the `useEffect`, after creating the corresponding HTMLElement. However, `<Portal />` has to use `forceUpdate` since mutating a ref will not cause the component to update.
The PR fixes that by saving the container of the `Portal` in a state, so no more `forceUpdate`.
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.

Currently, `next/dynamic` will opt-in to `React.lazy` if `{ suspense: true }` is used. And React 18 will always resolve the `Suspense` boundary on the server-side, effectively ignoring the `ssr` option.
The PR fixes#39609 by showing a warning message when `{ suspense: true, ssr: false }` is detected. The error documentation and the corresponding test case has also been updated.
In the future, Next.js could implement a custom version of `React.lazy` that could suspense without executing the lazy-loaded component on the server-side.

tsconfig behaves differently with `tsc` vs. Next.js. When `baseurl` is omitted, `paths` should be resolved against the tsconfig location. Consequentially, in this case the paths must start with `./`. This PR aligns Next.js behavior with `tsc` around `paths` without `baseurl`.

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]`.

Fixes: #38232
Fixes: https://github.com/vercel/next.js/issues/36893
Version [12.1.1-canary.5](https://github.com/vercel/next.js/releases/tag/v12.1.1-canary.5) introduced a bug, more specifically this PR: https://github.com/vercel/next.js/pull/34836
The issue described in #38232 is that the following code starts both the dev and prod servers:
```js
const start = require('next/dist/cli/next-start')
start.nextStart()
```
I searched a bit and found that `lib/get-project-dir.ts#getProjectDir()` now imports `bin/next.ts`
6b8e499c7b/packages/next/lib/get-project-dir.ts (L3)
and it calls a CLI command via
6b8e499c7b/packages/next/bin/next.ts (L137)
This `command` should not be defined, but it fallbacks to `defaultCommand`, which is `dev` (that explains why the dev server is also started)
This PR moves the `cliCommand` types and `commands` variable to a new separate file instead of `bin/next.ts`, to avoid running a CLI command when we import any file that also imports `lib/get-project-dir.ts`
Not sure how integration tests can be added for this issue, but feel free to tell me.

## Bug
When using next/server in different environment ([vitest](https://vitest.dev/)), named import will have runtime error.
```tsx
import { NextRequest } from 'next/server'
// TypeError: NextRequest is not a constructor
const request = new NextRequest()
```
This is conflicted with current `server.d.ts` files.
## Alternative
* reverte current `server.js` to esm, them compiled it to cjs.
In many browsers (other than Chrome), the `alt` text is visible while the image is loading. This causes a sense layout shift since you'll see a flash of text and then the image (although lighthouse measures 0 CLS, likely because Chrome doesn't have this problem). This PR updates `next/future/image` to hide the alt text, unless there is an error while loading the image in which case the `alt` text because relevant as the fallback.
Example:
<img width="115" alt="image" src="https://user-images.githubusercontent.com/229881/183128008-0660c50c-18aa-4e64-872e-ada9a652130f.png">
Unfortunately, Safari also shows a border while lazy loading images and it cannot be styled.
See upstream issue here: https://bugs.webkit.org/show_bug.cgi?id=243601
We were resizing animated images when importing them, but we don't optimize images when they come from an upstream provider. For consistency, we can skip resizing for local animated images as well.

Hi,
- Remove inlined CSS style which have minor performance loss. And hoist it to top of the component.
> Each time you inline an object, React re-creates a new reference to this object on every render. This causes components that receive this object to treat it as a referentially different one which have some performance pitfalls.
_Extremely sorry if I made any mistakes :(_
This PR removes the default styling of `object-fit:"contain"` for images using the future image component. This means images will get the default `object-fit` behavior of `"fill"`.
The main reason for this change is that an inline style will take precedence over external CSS, making this default behavior difficult to override with some styling strategies.

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 commit allows the users to import URLPattern from `next/server`,
by defining a key that uses `global.URLPattern`.
Why is this any good? or: why don't we add URLPattern to the global namespace?
URLPattern is exposed as global on Edge Runtime _only_. This means that if we define a
constructor in global namespace in our TypeScript definitions, people might
have runtime errors in their Node.js functions.
Importing from `next/server` enables users to get the constructor without
risking in runtime errors and wrong type definitions.
Keep in mind, that with the current implementation, we do not check if the
constructor actually exists, but `next/server` shouldn't be imported in
Node.js functions, AFAIK.

Fixes: [slack thread](https://vercel.slack.com/archives/C035J346QQL/p1659387244559979)
This PR adds a `fill` attribute to the future image component, that behave similarly to the fill mode on the existing image component.
Functionally, it mainly adds `position: "absolute"` and `object-fit: "contain"` to the image element, along with `height: "100%"` and `width: "100%"` to preserve the image aspect ratio. All of these can be overwritten by the user, except for `position: "absolute"`, which will throw an error. This is because changing that property without height and width is likely to cause layout shift.
Because we no longer have the wrapper element, this new version of `fill` requires that the user set `overflow: "hidden"` on the parent element themself, if they want that behavior.
This PR also includes several runtime checks to catch instances where the fill mode may provide unexpected results. These runtime checks warn if:
* The image doesn't have the `sizes` attribute and loads much smaller than the viewport
* The containing element does not have `position: "relative"`
* The image height value is 0

When we detect if `reactRoot` rendering should be enabled we `require` the require to check the version. But at that time the `NODE_ENV` isn't set yet. Then the react dev build stays in the `require.cache` that any future require of react will get the wrong build. In that case, React dev bundle is picked in production mode.
Fun fact: if you're using hooks, that seem not to effect you, but context consumer works different then you couldn't get the proper context from provider.

Closes: #30962
This PR adds a new `onReady` prop to `next/script` to handle shortcomings of the current `onLoad` prop. Some third-party providers and widgets require initialization code to run after the script's `load` event and every time the component is mounted. The `onReady` should solve that use case.
For more details, refer to the discussion in #30962.

* test: cleanup telemetry integration test
Instead of constantly parsing the console output, parse the output
once, convert the entries in JavaScript objects, then compare them
logically rather than textually.
* Collect telemetry for next/future/image
Track adoption of next/future/image and add relevant test.
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 adds handling for prefetching `onTouchStart` as this gives a little more time to start parsing required scripts for a page transition if not already done that can help make the transition faster. This is based on research showing the touch start event firing on average `90ms` before click (x-ref: [source](https://instant.page/#:~:text=in%20the%20world.-,On%20mobile,-A%20user%20starts))
This also adds testing safari with playwright so we can run these in PRs instead of only after merge and adds initial mobile testing as well.

Lands #37431 again, but it only solves the re-render issue completely for the middleware case (closes#38267), not the `rewrites` case (#37139).
For `rewrites`, the blocker is `isReady` always being `false` initially and to match the markup on hydration we can't simply work around it without a re-render. Need to come up with another fix.

The PR implements the details about un-extractable fields in the `UnsupportedValueError`.
The PR also enhances the warning message about the unrecognizable `config` field. Now the warning message will look like this:
```
warn - Next.js can't recognize the exported `config` field in route "/unsupported-value-type":
Unsupported node type "CallExpression" at "config.runtime".
The default config will be used instead.
Read More - https://nextjs.org/docs/messages/invalid-page-config
```
The corresponding production test case has also been updated.
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.

Fixes: https://github.com/vercel/next.js/issues/38783
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' }

## 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.

Drop the `next/streaming` endpoint. Currently it only holds the only one experimental api and we'd like to deprecate it in favor of oher future APIs for app dir
Currently, when a user forgets the `src` prop on an image, an error is thrown. However that error doesn't include any of the the user's code in the stack trace, so its nearly impossible to figure out which image is the culprit if there are multiple images on the page.
Since this error only throws on demand when a page is visited during `next dev`, we can instead delay the error so it no longer prints on the server but prints on mount instead. At that point, we'll have the `<img>` element via ref and can print it to the web console with the stack trace.

I noticed our internal comments about exported functions that should not be used in application code.
TSDoc has the [`@internal`](https://tsdoc.org/pages/tags/internal/) option that can be used together with TS's [`stripInternal: true` compiler option](https://www.typescriptlang.org/tsconfig/#stripInternal), hiding these from inferred types:
Before:
After:
It would also be great to use `/**/` comments instead of `//` when documenting methods/properties/functions, as these can be picked up by the editor when referring to these, so someone new to the codebase will hopefully have to jump around less to get some useful comments.

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.
Fixes#38533 by including `src/` as a default linting directory where all files within are linted

### Changes
#### Add missing virtual client entry matcher for css modules
client entry module has no file path, add the missing file matcher for client css modules loader
#### Use relative paths for imports in client entry to avoid module resolving failure.
if it's `next/head` or other 3rd party installed path, just import it instead of the resolved file path
Follow-up to #38682. Instead of checking if the full element is in the viewport we only check if the top of the element is in the viewport. If it is not we have to scroll back up in cases of navigating between items in the same layout for example.
* test: added some test cases for new client side router
* tests: added additional test cases
* test: improved test support
* feat: added support for `<Link soft />`
* tests: improved test reliability
* tests: added more cases for catch-all routes
* tests: added app -> pages -> app tests
* tests: add tests for useCookies + useHeaders
* tests: added tests for usePreviewData
* tests: added more tests for hooks and client components
* tests: added tests for query/params handling
* tests: fix tests for param/query to use props
* tests: added some skipped tests for unimplemented features
* tests: linting
* refactor: updated TODO -> TODO-APP
* tests: added some more test cases
* tests: skipped failing test
Temporarily we need to ensure that `<link>` tags are injected to `<head>` in the stream.

This PR introduces an environment variable that allows to modify the `EdgeRuntime` value on compilation time.
This is done to allow cloud providers like Vercel to have a different value, and enable user code and 3rd party libraries to have different code paths depending on the Edge Functions provider.

# 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
This is second attempt to https://github.com/vercel/next.js/pull/38076 . Most of changes are identical to previous PR. Main difference is introducing features `native-tls` and `rustls` for the sentry's downstream feature. Few platform targets we build (mostly where we cross compiles) fails to find native openssl for the specified target. For those, we falls back to rustls instead. The only exception is aarch64_windows, neither openssl nor rustls can be compiled straightforwardly, For those platform we bail out and do not init sentry at all. There are nearly 0 users on aarch64_windows anyway. We could try to located target's openssl binary, but the effort required seems not worth enough.
Also PR changed `server_name` property to not to include real device hostname to avoid possible PII concerns.

## 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):

## 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.
Client components might result in a page chunk or a standalone splitted chunk marked in flight manifest, this PR filters out the page chunk for standalone chunk so that while loading a client chunk (like for `next/link`) it won't load the page chunk to break the hydration. `chunk.ids` is not enough for getting required chunks, so we get the chunks from chunk group then filter the required ones.
tests: Re-enable few previous rsc tests
chore: refactor few webpack api usage

When an API route is detected for the `getRouteInfo` method (a route with a `/api` prefix), we should redirect the user to the original destination instead of the rewritten destination. This makes the behaviour consistent with how rewrites have been documented thus far.
The reproduction described in #37783 now causes an invariant violation error (for redirecting to the same URL), but this is instead related to the fact that the router (when rehydrated) attempts to redirect the user again to the correct destination. This should be corrected either in this PR or in a future one that addresses the hydration behaviour directly.
## Bug
- Related to #37783
- Related to #37949
## Example
With the following `next.config.js`:
```js
/** @type {import('next').NextConfig} */
const nextConfig = {
reactStrictMode: true,
async rewrites() {
return {
beforeFiles: [
{
source: '/:path(.*)',
has: [{ type: 'query', key: 'json', value: 'true' }],
destination: '/api/json?from=:path',
},
],
}
},
}
module.exports = nextConfig
```
The following link:
```jsx
<Link href="/not/real?json=true">
<a>Take me to JSON</a>
</Link>
```
When clicked, will navigate the user to `/not/real?json=true` and have it's contents served by `/api/json` and not simply redirected to `/api/json` which is incorrect.

this is a regression from the previous implementation where Next.js compiled Middleware using
the client compiler. We used to favor the browser exports over the `module` and `main`,
which allowed packages like `debug` to work without any changes on Edge Functions. This is
no longer the case, and this commit fixes that.
Side note: I believe that in the future we will also have a different key to symbolize edge
deployments. Maybe it will be `winter` to refer to WinterCG, but only time will tell!
Another side note: we need to add support for import maps for advanced use cases.

this commit allows to use EdgeRuntime as a dead code eliminator identifier:
```ts
if (typeof EdgeRuntime !== "undefined") {
console.log("will be stripped away");
} else {
console.log("will be kept in the bundle");
}
```
which means we're replacing `EdgeRuntime` with a literal

Previously we use custom webpack alias for specific react versions for non server side node runtime aliases. This PR alias the entire folders of `react/` and `react-dom/` so that no more alias in next.config is required but only the nodejs require hook.
* Alias `react` and `react-dom` by default
* Use `react@experimental` to run server components integration test
* Drop with-react-17 test util, add `__NEXT_REACT_CHANNEL` as an env var for testing and development to specify the react channel is 17 or new experimental version
* Requires prerequisite PR https://github.com/vercel/next-telemetry/pull/84
This PR adds telemetry to send list of the experimental swc plugins from next.config.js. Implementation largely mimics existing plugins telemetry for next_package (https://github.com/vercel/next.js/blob/canary/packages/next/telemetry/events/plugins.ts), with small modification to read swc plugin package instead.
One notable difference is swc plugin telemetry can be sent without version. This is due to swc plugins can be specified with absolute path without any npm pkg resolutions.

This ensures we properly alias and internalize `@swc/helpers` so that we don't rely on package managers hoisting this dependency for the build to work properly. This also disables the external helpers with `jest` as this can also require hoisting to work and doesn't provide as much of an optimization.

The `chunkFilenameMap` should take priority over the webpack built-in one here.

Fixes#38106.
Currently, the `shared/lib` directory (**which will also be shipped to legacy browsers**) is precompiled under `swcServerOptions`, which targets Node.js 12 and is way too modern:
- The public class field syntax is only supported since Chrome 72, Firefox 69, Edge 79, and Safari 14.1.
- Webpack currently doesn't support the public class field syntax as well (which causes the issue #38106)
- `async/await` syntax is also supported in Node.js 12 but not in the legacy browsers.
The PR fixes the issue by pre-compiling the `shared/lib` directory using `swcClientOptions` (which targets the ES5).
Note:
- The only way to validate the fix is to run an integration test case on a legacy browser.
- The output size is increased by a little. But the size impact can be minimized by enabling `@swc/helpers` (which I will bring up in the next PR)
This PR fixes the case when `next/future/image` is missing the width or height props.
It also fixes a case when `100%` or `100vh` were incorrectly parsed as `100` pixels.
This ensures we create any nested folders necessary when setting initial ISR cache entries with the filesystem cache. Also adds a regression test for this.

Fixes: https://github.com/vercel/next.js/issues/38130
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.

This PR attempts to setup native crash reporter for `next-swc`. Currently, it uses sentry internally, but it is subject to change depending on the usecase & needs. In any case it won't be breaking changes since this is not transparent to the end users.
PR sets up basic, minimal setup to collect crash reports only at the moment. We may want to expand & collect more data in native next-swc, but it is not clear what we need to collect / and I believe most cases next.js's js context can collect those data via existing telemetry. Crash report is an exception native handler can perform much better by having it in native context directly. While this is sent to different endpoint than telemetry, it is considered as same opt-in configuration. If telemetry is disabled, crash reporter won't collect as well.
The information collected by the reporter is minimally configured by sentry's sdk. These are the informations collected for example:
- device arch / family / model
- os kernel version / name / version
- runtime (rust) version / channel
- sentry sdk
- panic backtrace
- next.js release version
- device host name
There's no per-system uuid configurations yet.
It may need some audit if we need to omit some data included in above, while most of them seems ok to me.

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.

We don't need to include `<noscript>` for `next/future/image` since it uses native lazy loading instead of the `IntersectionObserver` (https://github.com/vercel/next.js/pull/37927).
The only case when we still need `<noscript>` is for `placeholder="blur"` because it requires client-side JS to switch the from blur image to final image on load.
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.

this makes all `experimental.images` options optional, so they can be toggled individually.

Fixes#37981.
When handling the legacy link behavior on the current version of Next.js, it only wraps single string child in `<a>` tag. The PR fixes the issue by also wrap single number child in `<a>` tag, too.
