For static metadata files, we should always generate static routes
instead of generate dynamic routes, so that they won't be deployed as
serverless functions which executing file reading in deployment
We decided in https://github.com/vercel/next.js/pull/48308 that we won't
use `turbo` when packing packages for tests.
This PR removes all code associated with that effort. The whole thing
fas behind a flag, so it shouldn't affect anything.
fix NEXT-1025
### What?
The team working on vercel.com reported that multiple pages were being
compiled when opening a single page. Investigated this a bit and found
it was caused by the matching logic (that also triggers compiling of
matched pages) running before middleware runs.
### How?
Removed this matcher logic, as far as I can tell it's not actually being
used. Probably a leftover from when we provided `page` as a middleware
parameter before we made middleware run in front of all resolving.

### What?
This PR enforces turbopack uses `automatic` jsx runtime.
- closes WEB-901.
### Why?
If you set `ts|jsconfig`'s `jsx` to any custom value, you'll encounter
next.js message
```
The following mandatory changes were made to your tsconfig.json:
- jsx was set to preserve (next.js implements its own optimized jsx transform)
```
Then internally transform sets jsx to use automatic runtime instead. In
case of turbopack, its transform pass is embedded so instead of setting
it to preserve falls back to automatic by default. PR doesn't handle
validations / or emitting user friendly messages yet, just enforce
runtime config regardless of how user sets it.
There maybe some additional followups to mimic exact transform existing
next.js does.

Currently POST requests to `"use server"` entries are not correctly
handled, and this PR partially fixes the behavior. Note that the
`isMultipartAction` case is still missing as we can't simply use
`busboy`. Later we'll unify the implementation here to always use
FormData via Undici.
Fixes NEXT-1026.
We've supported `export const config = { ... }` to sepecify `runtime`
etc. configs for pages under `app/` for a while. This PR is going to
drop it and only support `export const [config name] = [config value]`
per config
Add a warning if the legacy usage is detectd
Closes NEXT-1016
### What?
This PR ensures the jest configuration is json-serializable. It also
adds a bunch of typescript types.
### Why?
Jest requires that the configuration be json-serializable. See #47407
for details on the issues caused when it isn't. However, prior to this
commit, we were passing the entire next config as a property in the swc
jest transformer options. The next config includes some fields that are
not serializable, such as some functions.
### How?
In this PR we instead pluck the fields out of the next config that we
actually need and pass only those into the swc transformer.
This PR also adds a bunch of more precise typescript types where we were
previously just using `any`. This helps confirm that the configs are
being threaded through correctly. I think this type safety is enough to
confirm this commit and adding tests would just be redundant.

### What?
Rename originUrl to fetchUrl for clarity.
Also remove remove it from origin fetch annotation because the data is
redundant.
### Why?
- The word fetch better matches the other two parameters fetchType and
fetchIdx
- Because the fetch/origin URL is the actual URL being performed on the
origin fetch, it will always be duplicate data
### What?
* fix app dir chunking
* fix app dir 404s
* improve app dir performance
* rerender shadowportal on errors to re-add nextjs-portal to avoid empty
page
* inject polyfills before user code
* fix manifest generation
see also https://github.com/vercel/turbo/pull/4488
### Why?
App dir was very slow and lead to 404 errors
### How?
add included metadata to chunks to allow deduplicate chunk loads at
runtime
### What?
In environments where `FileSystemCache` is used, the cache for static
resources such as image files will be broken.
### Why?
Because `fs.readFile(path, 'utf8')` tries to read a file as a `string`.
### How?
Change to use `fs.readFile(path)` to always read files as binary
(`Buffer`).
### What?
This PR fixes misordered CSS `<link>` tags. CSS imports in inner layers
(e.g. a page) should always take precedence over outer layers (e.g. root
layout), but currently it's reversed.
### Why?
In layouts we usually define more general styles like globals, resets,
and layout specific things. And in inner layers and pages, things need
to be more detailed and override upper layers if there're any conflicts.
Previously we defined the component segment as
```tsx
<>
<Component {...props} />
{assets}
</>
```
which is necessary because of `findDOMNode` - if we put `assets` before
the component, we can't find the correct scrolling DOM and position for
that layer.
However, with `assets` being the last Float will receive the reversed
order of resources.
### How?
I changed the `createComponentTree` function to return a `Component` and
`assets` pair, so in the Layout Router they're no longer passed to the
scroll wrapper altogether but separately.

This PR fixes parallel routes navigation with `prefetch={false}`. This
was broken because the optimistic tree created when navigating with
prefetching disabled resulted in a state where the router tree was
expecting an incorrect node to be rendered and suspended until the
imaginary data arrived.
The fix consists of updating the method that creates the optimistic tree
in order to bailout of the optimistic tree creation when there are
multiple parallel routes for the current node.

This PR fixes a bug with interception where the rewritten path passed an
incorrect segment data on production, resulting in a 404.
The fix consists of moving the rewrite pre-processing step that rewrites
the dynamic segment from the originating path to when we actually
generate the rewrite. This is needed because that step does not run on
production. Now it does and signals correctly to the app-render that the
value for the segment can be determined from the path.
Also enables prod testing, which I had forgotten to enable.

While testing workflow changes noticed that when turborepo cache is
leveraged the `@next/env` types are missing causing unexpected failures
since the types aren't stored in the `dist` folder which is all that is
cached for the build step.
x-ref: https://github.com/vercel/next.js/commits/ijjk/update-ci-workflow
### What?
* Support `generateMetadata(props)` to dynamically generate multiple
metadata images at the same time
```js
// /app/opengraph-image.tsx
import { ImageResponse } from 'next/server';
export async function generateImageMetadata({params}) {
const images = await ...;
return images.map((img, idx) => ({
size: { width: 1200, height: 600 },
alt: img.text,
contentType: 'image/png',
id: idx,
}));
}
export default async function ({params, id}) {
const text = await getTextFor(id);
return new ImageResponse(
(
<div
style={{...}}>
{text}
</div>),
{ width: 1200, height: 600 },
);
}
```
### How?
Use `<metadata image>/[[...__metadata_id__]]/route.js` to catch all
metadata images id, and then use this `params.__metadata_id__` as id
argument for dynamic generate image.
If there's param, then we create `<metadata image>/<id>`, if there's
only 1 static image without dynamic `generateImageMetadata` then we keep
use `<metadata image>`
Closes NEXT-896
This ensures we don't fail to return the full body when storing to
fetch-cache in edge-runtime. Also ensures the fetch cache tests are
running for Node.js v16 correctly.
Fetch handling was also failing on Node.js v16 due to react's use of
`res.clone()` being broken with undici which is fixed in the latest
version of edge-runtime so this bumps that.

### Why?
Making the explanation more obvious because it took quite a while for me
to figure out the difference between catch-all and optional catch-all,
and I think others may feel the same way too.

This PR updates create-next-app's tailwind config to consider .mdx files
when it generates styles.
If you're using MDX, most of a project's styles are generated by the
other file flags, which can make it tricky to debug/notice the rare
subset from .mdx only.

### What?
Fixes a bug where `fetch()` to a page that calls `redirect()` would hang
infinitely.
### How?
The `Location` header was missing. The reason this wasn't surfaced
before is that we also inject the `<meta>` tag to redirect which the
browser would pick up to redirect too.

This updates the app route handler signature to be more correct to
prevent the issue with type casting:
```diff
- (request: Request, ctx) => Response
+ (request: NextRequest, ctx) => Promise<Response> | Response
```
This also ensures that the context paramter has the correct types:
```diff
type AppRouteHandlerFnContext = {
- params?: { [param: string]: any }
+ params?: Record<string, string | string[]>
}
```
