This PR changes the experimental `layout=raw` images to use the native lazy loading behavior (as opposed to the IntersectionObserver).
This will (eventually) lead to smaller client bundles and faster image loading since there is no JS needed to load the image.
However, we'll lose the `lazyRoot` and `lazyBoundary` behavior since those are specific to the IntersectionObserver implementation.
This fixes the interop default from https://github.com/vercel/next.js/pull/36877 on the jest `object-proxy` as it currently causes the below error when running tests in our `with-jest` example:
```sh
TypeError: 'get' on proxy: property '__esModule' is a read-only and non-configurable data property on the proxy target but the proxy did not return its actual value (expected 'true' but got 'false')
```

## What's in there?
Partially fixes https://github.com/vercel/edge-functions/issues/82
Relates to #36715
Our webpack plugin for middleware leverages static analysis to detect Dyanamic code evaluation in user `_middleware.js` file (and depedencies). Since edge function runtime do not allow them, the build is aborted.
The use of `Function.bind` is considered invalid, while it is legit. A customer using `@aws-sdk/client-s3` reported it.
This PR fixes it.
Please note that this check is too strict: some dynamic code may be in the bundle (despite treeshaking), but may never be used (because of code branches). Since this point is under discussion, this PR adds tests covering some false positives (`@apollo/react-hook`, `qs` and `has`), but does not change the behavior (consider them as errors).
## Notes to reviewer
I looked for test facilities allowing to download the required 3rd party modules. `createNext()` in production context made my day, but showed two issues:
- `cliOutput` is not cleaned in between tests. While clearance during `stop()` would be annoying, I hope that clearance during `start()` is better.
- if `start()` fails while building, the created instance can never be stopped. This is because we don't clear `childProcess` after `build`.

Implements the first part of #33227
- Applies browserslist to JS transforms when `experimental.browsersListForSwc` is enabled.
- You don't have to use browserslist, there's also `legacyBrowsers: false` which will be the new default in Next.js 13. See #33227 for which browsers and why. `legacyBrowsers` requires `browsersListForSwc: true` to function until it is the default.
```js
module.exports = {
experimental: {
legacyBrowsers: false,
browsersListForSwc: true,
}
}
```
I only implemented the JS part of the RFC, the CSS part should be handled in a follow-up PR.

* remove the experimental web vital hook api
* remove the exported flush effects api and only error on development, keep only usage to styled-jsx
for web vital hook API: The usage is not widly adopted since the existing exported vital api could do the same work. In the future we'll deprecate the `_app.server` in favor of `_app` in server component pages. so that this api won't be required.
for flush effects api: other css-in-js libs are not using the same approach like styled-jsx which holding a style registry and could flush it during streaming. emotion-js and styled-components are still relying on `Document.getInitialProps` atm and we have supported it in latest canary

The PR fixes#30300.
The previous integration test case only checks if `/out/404.html` exists. However, the test passes since `/out/404.html/index.html` is being exported instead.
The PR changes that by checking if a given path exists and is a file.
Stack trace disappears when error is converted to string.
I changed the types in `log.ts` to match `console.log`/`console.error`/`console.warn`.
fixes#31591
When getInitialProps is customized with react 18, since gIP requires to return `html` as doc property which could be used by user-land customization, we do blocking-rendering there and passdown the `html` to document

This PR introduces a more predictable API to manipulate cookies in an Edge Function context.
```js
const response = new NextResponse()
// set a cookie
response.cookies.set('foo, 'bar') // => set-cookie: 'foo=bar; Path=/'`
// set another cookie
response.cookies.set('fooz, 'barz') // => set-cookie: 'foo=bar; Path=/, fooz=barz; Path=/'`
// delete a cookie means mark it as expired
response.cookies.delete('foo') // => set-cookie: 'foo=; Path=/; Expires=Thu, 01 Jan 1970 00:00:00 GMT, fooz=barz; Path=/'`
// clear all cookies means mark all of them as expired
response.cookies.clear() // => set-cookie: 'fooz=; Path=/; Expires=Thu, 01 Jan 1970 00:00:00 GMT, foo=; Path=/; Expires=Thu, 01 Jan 1970 00:00:00 GMT'`
```
This new cookies API uses [Map](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Map) interface, and it's available for `NextRequest` and `NextResponse`.
Additionally, you can pass a specific cookies option as a third argument in `set` method:
```js
response.cookies.set('foo', 'bar', {
path: '/',
maxAge: 60 * 60 * 24 * 7,
httpOnly: true,
sameSite: 'strict',
domain: 'example.com'
}
```
**Note**: `maxAge` it's in seconds rather than milliseconds.
Any cookie manipulation will be reflected over the `set-cookie` header, transparently.

When using pnpm / yarnPnP to install next.js, styled-jsx as dependency is not hoisted in the top level node_modules, it will fail when nodejs is trying to resolve `styled-jsx/style` from project directory. Re-export `styled-jsx/style` in next.js and let swc/babel plugin compile the import path it to `next/dist/shared/lib/styled-jsx`

This PR brings some significant refactoring in preparation for upcoming middleware changes. Each commit can be reviewed independently, here is a summary of what each one does and the reasoning behind it:
- [Move pagesDir to next-dev-server](f2fe154c00) simply moves the `pagesDir` property to the dev server which is the only place where it is needed. Having it for every server is misleading.
- [Move (de)normalize page path utils to a file page-path-utils.ts](27cedf0871) Moves the functions to normalize and denormalize page paths to a single file that is intended to hold every utility function that transforms page paths. Since those are complementary it makes sense to have them together. I also added explanatory comments on why they are not idempotent and examples for input -> output that I find very useful.
- [Extract removePagePathTail](6b121332aa) This extracts a function to remove the tail on a page path (absolute or relative). I'm sure there will be other contexts where we can use it.
- [Extract getPagePaths and refactor findPageFile](cf2c7b842e) This extracts a function `getPagePaths` that is used to generate an array of paths to inspect when looking for a page file from `findPageFile`. Then it refactors such function to use it parallelizing lookups. This will allow us to print every path we look at when looking for a file which can be useful for debugging. It also adds a `flatten` helper.
- [Refactor onDemandEntryHandler](4be685c37e) I've found this one quite difficult to understand so it is refactored to use some of the previously mentioned functions and make it easier to read.
- [Extract absolutePagePath util](3bc0783474) Extracts yet another util from the `next-dev-server` that transforms an absolute path into a page name. Of course it adds comments, parameters and examples.
- [Refactor MiddlewarePlugin](c595a2cc62) This is the most significant change. The logic here was very hard to understand so it is totally redistributed with comments. This also removes a global variable `ssrEntries` that was deprecated in favour of module metadata added to Webpack from loaders keeping less dependencies. It also adds types and makes a clear distinction between phases where we statically analyze the code, find metadata and generate the manifest file cc @shuding @huozhi
EDIT:
- [Split page path utils](158fb002d0) After seeing one of the utils was being used by the client while it was defined originally in the server, with this PR we are splitting the util into multiple files and moving it to `shared/lib` in order to make explicit that those can be also imported from client.
This PR makes the following changes:
* Always add the `height` and `width` prop to image with `raw` layout (previously only added to images without `sizes`)
* Add a warning if a raw layout image is getting stretched (which can be caused by interaction of height and width prop with styles)
* Remove automatic aspect-ratio style from `raw` images. This is no longer necessary if all `raw` images have height and width props.
* Update tests and docs accordingly
Follow-up for https://github.com/vercel/next.js/pull/36463 this fixes an issue with optional catch-all params not being normalized correctly which was caught by the runtimes tests.

Fixes https://github.com/vercel/next.js/discussions/32233⚠️ If you're looking at this PR please read the complete description including the part about incremental adoption.
## TLDR:
Official support for `<Link href="/about">About</Link>` / `<Link href="/about"><CustomComponent /></Link>` / `<Link href="/about"><strong>About</strong></Link>` where `<Link>` always renders `<a>` without edge cases where it doesn’t render `<a>`. You'll no longer have to put an empty `<a>` in `<Link>` with this enabled.
## Full context
### Changes to `<Link>`
- Added an `legacyBehavior` prop that defaults to `true` to preserve the defaults we have today, this will allow to run a codemod on existing codebases to move them to the version where `legacyBehavior` becomes `false` by default
- When using the new behavior `<Link>` always renders an `<a>` instead of having `React.cloneElement` and passing props onto a child element
- When using the new behavior props that can be passed to `<a>` can be passed to `<Link>`. Previously you could do something like `<Link href="/somewhere"><a target="_blank">Download</a></Link>` but with `<Link>` rendering `<a>` it now allows these props to be set on link. E.g. `<Link href="/somewhere" target="_blank"></Link>` / `<Link href="/somewhere" className="link"></Link>`
### Incremental Adoption / Codemod
The main reason we haven't made these changes before is that it breaks pretty much all Next.js apps, which is why I've been hesitant to make this change in the past. I've spent a bunch of time figuring out what the right approach is to rolling this out and ended up with an approach that requires existing apps to run a codemod that automatically opts their `<Link>` usage into the old behavior in order to keep the app functioning.
This codemod will auto-fix the usage where possible. For example:
- When you have `<Link href="/about"><a>About</a></Link>` it'll auto-fix to `<Link href="/about">About</Link>`
- When you have `<Link href="/about"><a onClick={() => console.log('clicked')}>About</a></Link>` it'll auto-fix to `<Link href="/about" onClick={() => console.log('clicked')}>About</Link>`
- For cases where auto-fixing can't be applied the `legacyBehavior` prop is added. When you have `<Link href="/about"><Component /></Link>` it'll transform to `<Link href="/about" legacyBehavior><Component /></Link>` so that your app keeps functioning using the old behavior for that particular link. It's then up to the dev to move that case out of the `legacyBehavior` prop.
**This default will be changed in Next.js 13, it does not affect existing apps in Next.js 12 unless opted in via `experimental.newLinkBehavior` and running the codemod.**
Some code samples of what changed:
```jsx
const CustomComponent = () => <strong>Hello</strong>
// Legacy behavior: `<a>` has to be nested otherwise it's excluded
// Renders: <a href="/about">About</a>. `<a>` has to be nested.
<Link href="/about">
<a>About</a>
</Link>
// Renders: <strong onClick={nextLinkClickHandler}>Hello</strong>. No `<a>` is included.
<Link href="/about">
<strong>Hello</strong>
</Link>
// Renders: <strong onClick={nextLinkClickHandler}>Hello</strong>. No `<a>` is included.
<Link href="/about">
<CustomComponent />
</Link>
// --------------------------------------------------
// New behavior: `<Link>` always renders `<a>`
// Renders: <a href="/about">About</a>. `<a>` no longer has to be nested.
<Link href="/about">
About
</Link>
// Renders: <a href="/about"><strong>Hello</strong></a>. `<a>` is included.
<Link href="/about">
<strong>Hello</strong>
</Link>
// Renders: <a href="/about"><strong>Hello</strong></a>. `<a>` is included.
<Link href="/about">
<CustomComponent />
</Link>
```

## History
In PR #35889, `onError` prop was added explicitly on the `Image` component, but it was ommitted from the `ImageElement` component. In result, the callback didn't work at all.
## Now
This PR deletes the `onError` prop from explicitly defined props. Explicitly adding `onError` on the `const imgElementArgs` is considered, but deleting the defined prop from `Image` is more reasonable because the prop isn't used in `Image` component.

* Move nodejs ptah module usage to next-server, keep base-server and web-server headless for `'path'`
* Use a native module `path` for nodejs runtime and `path` polyfill for edge runtime
This adds a new test mode `next-deploy` which allows testing against deployments using the Vercel CLI. After running these tests they uncovered some bugs we need to correct before fully enabling. Patching the uncovered issues will be done in follow-up PRs and then after resolved this will be enabled to run after new publishes.
Tests that uncovered bugs to patch in follow-ups:
- [ ] test/e2e/getserversideprops/test/index.test.ts (req.url normalizing)
- [ ] test/e2e/i18n-api-support/index.test.ts (locale prefixed API routes matching)
- [ ] test/e2e/prerender.test.ts (/_next/data/build-id/ does not 404)
This ensures we strip ansi encoding from serialized errors as it causes the error to be illegible when rendered. This also adds a test for global CSS import being missing and then fixed.

There wasn't a strong reason to choose `renderToStream` over `renderToStaticMarkup` for the document wrapper. But due to problems like #35870, we can switch back to the static renderer for now.

Even though we never documented it, the `onLoad` prop used to work (in most cases) in Next.js 12.1.4 and broke in 12.1.5 once the code was refactored in PR #35889.
We still shouldn't document it because `onLoad` doesn't work in all cases so [`onLoadingComplete`](https://nextjs.org/docs/api-reference/next/image#onloadingcomplete) is preferred, however tests were added for the cases that do work.
Use cases that don't work with `onLoad` are Data URLs as well as `loading="eager"`.

The `config` was changed from a global variable to a function parameter of the `loader()` function in PR https://github.com/vercel/next.js/pull/33559 as an implementation detail, not as a public API. It was not meant to be used by the end user which is why it was [undocumented](https://nextjs.org/docs/api-reference/next/image#loader).
This config is meant for the default Image Optimization API. Since the `loader` prop bypasses the default Image Optimization API in favor of a custom function, that config is no longer be relevant because the function can implement the optimization url however it desires.

The logic for finding a user's custom `.eslintrc` config file is missing a check for `.eslintrc.cjs`, which is listed as one of the valid filenames in ESLint's docs:
https://eslint.org/docs/user-guide/configuring/configuration-files#configuration-file-formats
...so this PR makes `next lint`'s list of possible config files consistent with ESLint's.
I stumbled upon this when trying to rename my own config file, since I've pretty much moved completely to ESM by now... but [ESLint doesn't support modules yet](https://github.com/eslint/eslint/issues/14137#issuecomment-785421664), so renaming the file to `.cjs` just keeps things cleaner (and VS Code happier). This is my first PR here so even though I've only changed a couple of lines, please let me know if I'm overlooking something! 😊

## History
In PR #24153, `placeholder=blur` was added and it set `element.style.backgroundImage = 'none'` instead of using react state to re-render. Then in PR #25916, a delay was added to handle removing the blur placeholder. Then in PR #25994, `img.decode()` was utilized but we found this caused problems in Firefox in #26011.
## Today
This PR changes the the blur placeholder removal to use react state to re-render. This _should_ prevent Firefox from erroring although we should probably keep the catch() just in case. This was pointed out when React 18 caused subtle differences in Firefox in this comment https://github.com/vercel/next.js/issues/30128#issuecomment-1086754374
This updates our `yarn next` command to leverage react v18 by default and removes the need for the test require hook/config modifying when testing react 18. There are some fixtures we need to investigate react 18 support in follow-ups:
- `test/integration/client-navigation-a11y`
- `test/integration/critical-css`
- `test/integration/custom-error-page-exception`
- `test/integration/font-optimization`

* Only reading page runtime when `reactRoot` is enabled, reduce time for react 17 apps
When using streaming SSR decodeText is called repeatedly with incoming
chunks of data. In that case a multi-byte character may occasionally
split between chunks, causing corruption. By setting the TextDecoder
option 'stream' to true, and reusing the same TextDecoder instance,
TextDecoder will memorise “unfinished” characters and decode them when
the next chunk comes.
Static optimization is now supported with concurrent features, this PR fixes the condition for `useStatic404`.

Minor improvements to the integration test runner to emit process's stdout when its execution failed.
We have `console.log` for the output, but it doesn't emit actually since jest suppresses console output unlesss _assertion_ fails. If we throws in `before*` hook, since there's no actual assertion fails jest won't release captured console logs.
PR adds one straightforward workaround (https://stackoverflow.com/questions/48695717/console-log-statements-output-nothing-at-all-in-jest) to emit if process exits with non-zero errorcode. To avoid any existing behavior, this is not enabled for the cases when process successfully exits.

### source changes
* Error dynamic suspense option in non concurrent mode, don't check react root anymore since they should be bound
### tests changes
* Remove duplicated rsc client test
* Merge type checking cases (`next/dynamic`)
* Remove blocking rendering tests cases since we should opt-in Fizz rendering when using React.lazy
* Remove some thrown promises cases, leverage the streaming component we had in RSC test
In this test we are mainly focusing on the SSR'd result so hydration is't critical, but it will definitely help to get rid of these hydration errors.

This fixes our package manager detection which was changed slightly in https://github.com/vercel/next.js/pull/34947 for `pnpm` support to ensure the default case still attempts detecting the available package manager if no preference is specified in the command args. This also adds a test case to ensure the install succeeds when we fail to detect a valid `yarn` binary and no preference is set via the `npm_config_user_agent` env variable.

We need to handle cjs cases for client/server components when they're compiled to commonjs in some cases.
e.g. if there's an internal `_app.server.js` in nextjs, the assets in the dist files are compiled to cjs by swc. Or any 3rd party libraries are consumed could be cjs only.
### How it works
* Detect the source file is ESM or CJS first by detect if there's any ESM import/export
* Append the new exports or collect exports info based on the module type
.substr() is deprecated so we replace it with .slice() which works similarily but isn't deprecated

I noticed a few issues that had "Output from `next info`" with the first line as
```

This was because `execSync()` was still printing to stderr when a command was not found.
Changing to `execFileSync()` fixed it so we no longer print to stderr when a command is not found.

Currently we ignore any files that are traced and handled by a webpack loader to prevent including webpack specific files although users may attempt reading files directly using `fs` even if they are handled by webpack so this leverages the new reason types in `@vercel/nft` to only ignore if it is solely imported.

### Bugfix
Made some changes for the data register buffer flushing in #34631 and #34475 that tried to delete the buffer or flush them only once. But turns out it will break the navigation between RSC pages.
### Enhancements
Simplify the inline response writer and inline response data for the initial render. Since they're only for the initial render, navigations will leverage the serialized data fetched from router and construct the react tree.

Related to #31678
For streaming pages,
Nodejs runtime: setting global runtime to `"nodejs"` will work with default module resolution.
Edge runtime: previously next.js will pick up browser field since it's the "similar" asset (unlike nodejs) to edge runtime but browser specific things like DOM api could breaks cause edge runtime is more like worker without dom runtime.
This PR is to revert the main field resolution behavior. And if you have a library targeting multiple runtime with different fields, ideally is to make it more isomorphic and will be easy to use in edge runtime
This PR depends on #35242 and #35243. It allows the global runtime to be unset, as well as enables static optimization for Fizz and RSC pages in the Node.js runtime. Currently for the Edge runtime pages are still always SSR'd.
Closes#31317.

This PR adds a new layout mode for images called `raw`, as discussed with the core team a while back. This mode has the following characteristics:
- No wrapper `span` around the `img` element
- No sizer svg
- Almost no styles automatically added to the `img` element
- `style` parameter is allowed and is passed through to the underlying `img` element
This also adds documentation changes to describe the new component.
There are a few tradeoffs and DX decisions that may warrant discussion/revision before merging. I'll add a few comments to highlight those issues.
- Related to #18637
## Summary
This PR adds a new `worker` strategy to the `<Script />` component that automatically relocates and executes the script in a web worker.
```jsx
<Script
strategy="worker"
...
/>
```
[Partytown](https://partytown.builder.io/) is used under the hood to provide this functionality.
## Behavior
- This will land as an experimental feature and will only work behind an opt-in flag in `next.config.js`:
```js
experimental: {
nextScriptWorkers: true
}

- For Partytown to work, a number of static files must be served directly from the site (see [docs](https://partytown.builder.io/copy-library-files)). In this PR, these files are automatically copied to a `~partytown` directory in `.next/static` during `next build` and `next dev` if the `nextScriptWorkers` flag is set to true.

This PR fixes#31517.
Previously we only run `PagesManifestPlugin` in the Node server runtime, because the Edge target doesn't need it as the web server and middleware SSR loader specially handled pages manifest. This cases entrypoints with the Edge runtime configured being missing from there and this PR fixes it.
Part of #31317 and #31506.

Partially implements #31317 and #31506. There're also some trade-offs made with this PR: since we can't know if a certain runtime will be used or not beforehand, we have to start both runtime compilers (Node.js and Edge) and then generate entrypoints correspondingly.
Note that with this PR, the global runtime is still required to use the per-page runtime.

* Add failing colon rewrite test
* add test fixture
* better colon rewrite tests
* middleware rewrite colon tests with query parameters
* fix#31523
this addresses the symptom but the real systemic issue is that prepareDestination is called on rewrite/redirect URLs, which have no defined special behavior for colons and they should not be compiled at all
* hack around prepareDestination to skip compiling x-middleware-rewrite
this is a bit nicer than just escaping colons, but ideally we find a way to obviate prepareDestination
* obviate prepareDestination for x-middleware-rewrite handling
* don't clobber rewrite query data
* omit redundant type
* catch up to main
* It looks like newUrl should contain only pathname

We currently use `dotenv-expand@5` in `@next/env`, which does not support default expansion. It was added in v6 (https://github.com/motdotla/dotenv-expand/pull/39).
Upgrading to the latest version of `dotenv-expand` and fixing an import, the added test passed.

This gracefully handles errors when the `url` query string param looks like an internal image because it starts with `/` but it is not pointing to an internal image.
Previously, this was printing an unnecessary stack trace when the upstream content-type was undefined.

Adds an API config option that disables warning a user when their API response body is over 4 megs. This has been added for users who'd like to stream larger amounts of data from their API acknowledging the drawbacks. This config mirrors the existing [`externalResolver` config](https://nextjs.org/docs/api-routes/api-middlewares#custom-config).

If there's upcoming streaming data from server components, should safely skip the bootstrap process. Previously we deleted the buffer then it will cause the buffer is missing in the later re-renders. Now we mark it as empty array, so it can safely skip the boostrap phase

This removes the config for the `commons` chunk.
I think the idea was that modules are that in all pages are put into a `commons` chunk, but that breaks when next/dynamic comes into play, which also creates chunks. So the `totalPages` condition is broken and could lead to too many modules placed into the commons chunk.
Example: 2 pages, each has one next/dynamic. Both on demand chunks include module A. page 1 includes module B and next/dynamic on page 2 includes module B. A and B are placed into commons. commonjs chunk is loaded in page 1 and both next/dynamic. Page 1 would load module A even while it doesn't need it.

Currently, we print warnings during `next dev` for every render of `next/image`, which can quickly fill the console making it really unfriendly to developers trying to read the logs.

Also fixed the issue that the `env` field is empty when the `process` module is used as the value of the variable (which happens when the module is contained in a dependency of application).

Implements https://github.com/vercel/next.js/issues/30997 with some minor tweaks to the design:
* The hook is moved to Client Components (e.g. `pages/_app` instead of `pages/_document`). This was a silly oversight in the original design: the hook needs to be called during server prerendering.
* `useFlushEffects` instead of `useFlushEffect` as there isn't a particularly safe way to implement the singular semantics as a Client Component hook given the current implementation of server rendering.

Visiting the following page will call gSSP indefinitely in a loop and logs errors from `on-demand-entries-client`:
```js
const Home = () => null
export default Home
export function getServerSideProps() {
console.log("gssp called")
return { notFound: true }
}
```
We should not keep fetching the page if it returns 404 as it can introduce unnecessary data requests.

To collect the requests starting from page load, we need to register event listeners before page loading (`page.goto` API invocation). By default webdriver will wait for hydration, so we need to register events inside `browser.loadPage` to ensure we can collect the requests before hydration is done.
### Changes
* Add `beforePageLoad` for next webdriver
* registry page `'request'` event before loading page
* update related tests for agruments change
### Usage
```js
browser = await webdriver(appPort, '/path', {
waitHydration, // default true
retryWaitHydration, // default false
disableCache, // default false
beforePageLoad, // default undefined
})
```

This PR removes the experimental `optimizeImages` flag. This feature was designed to automatically add preload tags for images, but I was never able to get it to do a very good job of selecting the images that actually need preloading.
This feature never graduated from experimental and in fact we never even publicized it as an experimental feature for people to try.
Additionally, even if someone was using this feature, it wouldn't have a functional effect, only a performance effect (removal of some preloads).
For those reasons, I believe it is safe to remove this functionality and that it is not a breaking change.
As the comment mentioned, React 18 with Strict Mode enabled might cause double invocation of lifecycle methods. This makes the `<RouteAnnouncer/>` being non-empty for the initial page, which is a bug (it should only announce page change whenever a navigation happens).
