### What?
This PR fixes `next/link`'s `<Link />` missing many `<a />` props when
`experimental.typedRoutes` is enabled.
### How?
It does that by changing `AnchorHTMLAttributes<HTMLAnchorElement>` in
LinkRestProps to
`DetailedHTMLProps<AnchorHTMLAttributes<HTMLAnchorElement>,
HTMLAnchorElement>`, which contains all `<a />` props.
Fixes#51907

This PR changes `fs.stat` calls (to check if a file exists or not) to be
aggregated as `fs.readdir` calls and cached during the entire loader
pass. This is because we have a huge amount of file to check, but they
are always in a small amount of directories.
For example, a route that's 5-directory deep (`/a/b/c/d/page.js`) can
have up to 4,000 special segments and metadata files to check. However
they're always under these 5 directories. So instead of 4,000 `fs.stat`
calls let's just do 5 `fs.readdir` calls.
Didn't measure it carefully but a quick local test shows a 20~30%
improvement.
<details>
<summary>Another idea for future improvements</summary>
Currently, we create a MissingModuleDependency for any combination of
possible metadata filename. But in reality, we only need to track them
incrementally by index. For example if `icon1.js` is missing, it's kinda
waste to still track `icon2.js`~`icon9.js` because `icon1.js` will be
added first. This change should at least reduce the number of file
watchers by 80% and the initial compilation time by 0.5~1s, depending on
the actual route.

### Description
This PR refactors the Image component so that the core logic can be consolidated into a single function.
This allows usage outside of `<Image>`, such as:
1. Working with [`background-image`](https://developer.mozilla.org/en-US/docs/Web/CSS/background-image) or [`image-set`](https://developer.mozilla.org/en-US/docs/Web/CSS/image/image-set)
2. Working with canvas [`context.drawImage()`](https://developer.mozilla.org/en-US/docs/Web/API/Canvas_API/Tutorial/Using_images) or simply `new Image()`
3. Working with [`<picture>`](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/picture) media queries to implement Art Direction or Light/Dark Mode images
### Example
```tsx
import { unstable_getImgProps as getImgProps } from 'next/image'
export default function Page() {
const common = { alt: 'Hero', width: 800, height: 400 }
const { props: { srcSet: dark } } = getImgProps({ ...common, src: '/dark.png' })
const { props: { srcSet: light, ...rest } } = getImgProps({ ...common, src: '/light.png' })
return (<picture>
<source media="(prefers-color-scheme: dark)" srcSet={dark} />
<source media="(prefers-color-scheme: light)" srcSet={light} />
<img {...rest} />
</picture>)
}
```

### What?
Adds `payload` to the external package list
### Why?
To prevent developers using
[Payload](https://github.com/payloadcms/payload) modules within Next.js
from having to add this in their next config.
### What?
This ensures the `request.signal` `AbortSignal` that every Pages API and App Route handler receives aborts when the client disconnects.
### Why?
Now that we [support cancelling](https://github.com/vercel/next.js/pull/51594) responses mid-stream, it's important that we can communicate that abort to developer code. Eg, for AI endpoints that have an streaming `fetch` connection to the some 3p AI service, it's important that they're able to abort that stream when the client's browser disconnects.
### How?
Just need to listen for `error` events on Node's `IncomingMessage` request object, and forward that to an `AbortController`. After that, propagate the signal through the server to web-style handlers.
After migrating a Next.js app from Pages Router to App Router and using as many RSC as possible, I notice that the client js bundle size actually increases by 5%. It turns out that Next.js has introduced a lot of code to the client bundle.
<img width="1354" alt="image" src="https://github.com/vercel/next.js/assets/40715044/c7216fee-818b-4593-917e-bf0d2a00967a">
The PR is an attempt to reduce the client bundle size.
This PR makes the server code be minified.
## Why
This will improve performance of the server code because of the lesser
size, lesser time to parse and lesser code via tree sharking.
Cons: this should lead to increased build times, so a
`disableServerMinification` config was added

To enable the ability of leveraging current `pathname` and configured `metadataBase` for other canonical like urls, we support those urls with auto resolving with `pathename` and `metadataBase` like canonical url, then you could just configure relative paths like below
```js
openGraph: {
url: './abc', // will be resolved based on pathname and metadata base
},
itunes: {
appId: 'my-app-id'
appArgument: './native-app'
}
```
Fixes#51829
Closes NEXT-1302
### What?
Node.js sets stdout to non-blocking by default, rust expects it to be blocking
so when logging a lot of data, it can happen that rust receives an error while writing causing it to panic, the error is just that the resource is temporarily unavailable, but rust doesn't handle this case
See https://github.com/napi-rs/napi-rs/issues/1630
## What?
In the first implementation of App Router a year ago I added `return
null` for this case which is incorrect as we have to suspend rendering
when doing a navigation.
The logic in `app-router.tsx` already handles that automatically. The
logic in layout-router is no longer needed as the flightData will be
applied automatically in the reducer.
## How?
Removed the logic when the fetch returns a path to mpaNavigate to.

Removed an unnecessary dependency mapping from the plugin.
Here's a quick visualization of this change. We have to traversal the module graph twice. The first iteration goes through all server modules and creates the client entries. And the second iteration collects info from all client modules.
Before this PR, the second iteration starts from server entries so it traversals both layers. With this PR, the second iteration will start from client entries only:

This is a ~100ms improvement for HMR of complicate apps.
### What?
`next build` is incorrectly reporting file size stats for the root path
when using the app dir
### Why?
In #50768, the denormalization logic was removed for appDir routes, but
`pagesManifest` has the root page keyed by `/` while the actual path
will be `/index`.
### How?
This re-adds a simpler denormalize function that just replaces `/index`
with `/`.

This is already the default for production build, but we are also enabling it for development. It has small perf impact as gzip takes time, but it significantly improves the disk usage and time for reading and writing to the filesystem. This is especially the case when working on a large codebase and we are transpiling and bundling more modules now.
## Background
Currently we're track all imported CSS modules by an entry, in the
client manifest:
```js
// client manifest
{
entryCSSFiles: {
'app/entry_name': {
modules: ['app/foo.css', ...]
}
}
}
```
And then, in the font manifest we track all emitted assets (fonts) by
each CSS module:
```js
// font manifest
{
app: {
'app/foo.css': [
'static/font/abc.woff', ...
]
}
}
```
These two fields are only used together by `get-preloadable-fonts.tsx`,
so it can know which font files need to be preloaded for this entry.
(Although previously we use `.modules` for something else, but it's gone
now)
## Changes
Since we only need the font assets per entry, it's unnecessary to track
these in the module level and then join them together. This PR removes
the `modules` field from the client manifest, and changes the font
manifest to directly keep the entry—font mapping.
This gets rid of one module traversal from the client manifest plugin.
An annoying issue that slows down compilation times in dev for Next is
that we might trigger compilation of a page via hover on app.
We do this because we want the same experience in production and dev and
the prefetching is important for instantaneous loading states.
The alternative in this PR is that we don't prefetch at all anymore in
dev but instead, when we handle navigation, we can force a prefetch
navigation.
The slight compromise with this approach is that you can't test
prefetching anymore in dev.

Instead of traversing the entire client module graph twice (!), this PR
changes it to only traverse the client **entry** modules only. Because
of the way we create client entries, all client modules' _boundaries_
can be retrieved via all outgoing connections of all chunks' entry
modules, filtered by `next-flight-client-entry-loader`.
This brings down the time complexity from `2 * num_client_modules` to
`num_client_entry_modules`.
Closes#51240.
Additional notes from @timneutkens
- Removed `module.unsafeCache` as it seemed to be leaking modules across
multiple compilations, this should help with memory usage
- Changed entry-loader to have consistent module import map (sort it) to
ensure cache key is consistent

Limit the number of Watchpack's watchers to 20 for the routing worker which runs Watchpack. By default this value is 2000 on macOS and 10000 on Windows, which can hold too much resource.
This PR fixes tree-shaking for the metadata image generation module
(e.g. `opengraph-image.js` and other conventions) when the page has
`runtime = 'edge'`.
## Details
The first step of this fix is to change this from the loader:
```js
import * as exported from "./opengraph-image.js"
```
to be necessary fields only (so the `default` export can potentially be
removed):
```js
import { alt, size } from "./opengraph-image.js"
```
To know which fields are exported, we need to load the module first via
Webpack loader's `loadModule` API and check its
`HarmonyExportSpecifierDependency` dependencies.
This is the first step to make it tree-shakable. Since we have
`./opengraph-image.js` used in another entry, the actual image API route
`opengraph-image/route.js`:
```js
import * as image from "./opengraph-image.js"
```
Webpack still treats both as the same module and generates one chunk for
it. We want to "fork" it into two modules. The technique here is to add
a noop resource query and make it:
```js
import { alt, size } from "./opengraph-image.js?__next_metadata_image_meta__"
```
So it won't be shared in the chunk (as it's a different request), and
can be concatenated inline.
However that's not enough, the inlined result will still have all
imports from our `opengraph-image.js`, including `import { ImageResponse
} from 'next/server'`. Because we can't simply add `"sideEffects":
false` in Next.js' package.json, we need a way to mark this import as
side-effect free. I went through
https://github.com/webpack/webpack/blob/main/lib/optimize/SideEffectsFlagPlugin.js
and used the same method to mark that module with
`module.factoryMeta.sideEffectFree = true`.
With all these added, the page bundle will no longer contain the
`ImageResponse` instance.
## Result
The difference is quite amazing, for the new added test (an empty Edge
runtime page with an opengrah image file) here're the before/after
metrics for the `page.js` server bundle:
Edge bundle size: 892kB → 500kB.
Build time: 26.792s → 8.830s.
### What?
Interception route rewrites are not properly parsing catch-all segments,
which leads to "missing parameter name" errors when passed to
`pathToRegexp`.
### Why?
The existing `toPathToRegexpPath` function ignores `...` and keeps it as
part of the regexp path. This means `pathToRegexp` will attempt to
handle `/foo/bar/:...baz` and `/foo/bar/:[...baz]` rather than
`/foo/bar/:baz*`
### How?
The regex used for matching the path was updated to support the dynamic
optional segment, and then we special case catch-all segments
Fixes#51784
---------
As noted in the comments, it's necessary to always add optional dependencies as missing dependencies even if they exist because they might be deleted and re-added.
Closes#51763.
Close the circle after #51104. The name "size limit" can be confusing as it could also mean the size of the Server Action function itself, so this PR changes it to `serverActionsBodySizeLimit` and makes sure it's well documented.
This adds support for matching against the user-agent header when doing rewrites client side.
Currently a rewrite like this will fail because the user-agent header is not provided, and so next.js tries to prevent infinite rewrites:
```
{
source: '/:path*',
destination: 'https://example.com/:path*',
missing: [
{
type: 'header',
key: 'User-Agent',
value: '.*(?:Electron).*'
},
],
}
```
Adding in the user-agent header allows this rewrite to pass.
Adding `nextConfig.output` to next-info output so that we could determine if users're using standalone mode if the reproduction is not clear or missing sometimes
Example output
