This ensures revalidate can be fetch specific instead of cache key
specific and adds a test case to ensure config based revalidate isn't
overridden by fetch based revalidate.
* Add `manifest.webmanifest` and `manifest.(j|t)xs?` support for
manifest.json route
* Add `Manifest` type for it for autocomplete purpose.
Remove the exports for `SitemapFile` and `RobotsFile` globally, will
discuss how to re-export them with better naming later
Small fix for `Robots` typing, should allow `string | string[]` for user

This serves to correct a specific issue related to multiple locales being specified in the pathname as well as some general i18n improvements.
- Multiple locales are now parsed correctly (only taking the first locale, treating the rest of the string as the pathname)
- `LocaleRouteNormalizer` has been split into `I18NProvider` and `LocaleRouteNormalizer` (tests added)
- Adjusted the `I18NProvider.analyze` method (previously `LocaleRouteNormalizer.match`) to require the `defaultLocale: string | undefined` to ensure consistent behaviour
- Added more comments around i18n
Resolves#39689, partially resolves#28642 (see notes below)
Inspired by #44627
In #28642 it was also asked to expose `server.headersTimeout`, but it is
probably not needed for most use cases and not implemented even in `next
start`. It was needed to change this option before
https://github.com/nodejs/node/issues/27363.
There also exists a rare bug that is described here
https://github.com/nodejs/node/pull/32329#issuecomment-614119125. To fix
this exposing `server.headersTimeout` might be required both in
`server.js` and in `next start`.

Currently all import CSS resources, including CSS modules, are imported lazily. This means that they can't be chunked as by definition of "lazy" they can be loaded separately.
This PR changes it to always use "eager" so if they're in the same entry, these CSS resources can be chunked together and reduce the total amount of requests. However the downside will be tree shaking, as not all modules in a chunk are used by one entry. Two entries can only share a part of it.
Since CSS modules won't have side effects this should be a good trade off.

Currently if `notFound()` or `redirect()` is called when the shell was already sent out, we can no longer change the status code and head tags. In that case we inject these specific meta tags into the HTML stream so specific agents can read them.
fix NEXT-220 ([link](https://linear.app/vercel/issue/NEXT-220))
Generated metadata icons through api routes instead of using webpack
emitting file. Each metadata image file will go through
`next-metadata-image-loader` to get the image basic info, and then it
will go through `next-metadata-route-loader` to be converted as a
routes.
Related to NEXT-264
Closes NEXT-810
The old `test_generator::test_resources` could only find resources relative to the project root, and not relative to the test file. Because of the new nextpack directory structure, this causes all kinds of headaches between running in nextpack and running in turbo (`next.js/packages/next-swc` vs `nextpack/next.js/packages/next-swc`).
When calling the server (via `callServer`), we concat all closure values
(`$$bound`) and arguments of the function call into one array on the
client. Hence on the server, we will have to compile the function
differently to support that.
With this change, the compiled function will have a `$$with_bound` flag
to indicate that if it accepts closure values. If so, the only argument
passed will be an array like `[...bound_values, ...fn_args]`, and we
compile the function parameters to `(closure, arg1 = closure[N], arg2 =
closure[N + 1], ...)` where `N` is the number of the closure
identifiers. This way we can still fill these arguments by only pass an
"bound + args" array. If it doesn't accept closure values, it will be
directly called with `...fn_args` so no compilation change needed.
The reason that we use `arg1 = closure[N]` is that this can support
complex patterns in parameters such as `f(closure, {a} = closure[1], [b]
= closure[2])`.

x-ref: [slack

Follow-up to https://github.com/vercel/next.js/pull/46317. The issue is
that, if:
- `experimental.clientRouterFilter` is enabled
- `i18n` is enabled with `defaultLocale` set
- Next.js router navigates to a path that (1) is the same as
`defaultLocale` and (2) will be redirected,
then:
- **Expected:** Should hard-navigate to this path without any locale
prefix (and then redirect occurs)
- **Actual:** Hard-navigates to this path with `defaultLocale` prefix,
even though it's not needed (and then redirect occurrs)
### Solution
This PR fixes the above issue by adding `defaultLocale` to `addLocale`
which is passed to `handleHardNavigation`. [`addLocale` skips adding the
locale if `locale` is equal to
`defaultLocale`](02125cf3b1/packages/next/src/shared/lib/router/utils/add-locale.ts (L17)).

fix NEXT-827 ([link](https://linear.app/vercel/issue/NEXT-827))
This aligns use of the next/font transform across the workspace under a
single crate, now called `next-transform-font`.
### What?
This PR introduces a new `--tailwind` flag to the `create-next-app` CLI,
to make it easier to bootstrap a Next.js app with Tailwind CSS
pre-configured. This is going to be the **default**. To opt-out of
Tailwind CSS, you can use the `--no-tailwind` flag.
### Why?
Tailwind CSS is one of the most popular styling solutions right now, and
we would like to make it easier to get started.
Currently, the closest you can come to this is by running `pnpm create
next-app -e with-tailwindcss` which will clone the
https://github.com/vercel/next.js/tree/canary/examples/with-tailwindcss
example. But that example is not configured for the App Router. This PR
will let you add Tailwind CSS to both `app/`, `pages/`, and start out
with TypeScript or JavaScript via the CLI prompts.

https://twitter.com/samselikoff/status/1634662473331617794)
### How?
We are adding 4 new templates to the CLI bundle.
> Note: The styling is not pixel-perfect compared to the current
templates (using CSS modules) to require fewer overrides, but I tried to
match it as close as possible. Here are a few screenshots:

#### For reviewers
This introduces 4 new templates, with a very similar code base to the
original ones. To keep the PR focused, I decided to copy over duplicate
code, but we could potentially create a shared folder for files that are
the same across templates to somewhat reduce the CLI size. Not sure if
it's worth it, let me know. Probably fine for now, but something to
consider if we are adding more permutations in the future.

This PR makes sure that we are not appending statements after the function or arrow expression, if they're actions. Instead we put all them in a `ParenExpr` so the entire thing can be defined inline.
fix NEXT-813 ([link](https://linear.app/vercel/issue/NEXT-813))
Previously when we move to metadata images to custom app routes, when the image files get imported, it matches the `next-image-loader` rule which accidentally generate a static file into media.
This PR appends the metadata reource query to the imported rerource, and then skip in the `next-metadata-route-loader` so they won't get applied by image loader or emit any unexpected assets
Ensures `router.refresh()` matches the upcoming `revalidatePath('/')`
api. This also ensures that when server context has changed it applies
to all routes, not just the one that triggered the refresh.
- When `router.refresh()` is called we fetch the full RSC payload from
the server (root layout till the page)
- The client-side router cache is fully invalidated, effectively making
it empty
- The client-side router prefetch cache is fully invalidated,
effectively making it empty
- RSC payload is applied to the state

### What?
This PR fixes the issue where files from other directories are allowed into type `Route`.
### Why?
It is caused by the fact that `this.collectPage` only blocked files in `appDir` that are not `page.js` and `pages/`'s `_app.js`, `_document.js`,...
### How?
This fixes that by blocking files that are not in any of these directories as well.
Closes NEXT-
Fixes#47151
In short, this PR adds a 3rd layer to the server compiler. This extra
layer is for marking the modules when re-entering the server layer from
a client component. It is almost identical to the existing server layer
and it should have all the same bundling and runtime behaviors, but it's
still special because it's not allowed to enter the client layer again
from there.
Because of that, we create the extra entry for that new layer when the
client layer compilation finishes in the `finishModules` phase. The new
entry is handled normally as it's in the server layer. But the original
module in the client layer will be compiled specially as special no-op
exports, and will then be connected via the `callServer` wrapper.
fix NEXT-809 ([link](https://linear.app/vercel/issue/NEXT-809)).
Builds on https://github.com/vercel/turbo/pull/4202 to implement custom Next.js Transformers in Turbopack.
This is the final piece to moving the `next-*` crates to Next. While we've _technically_ moved everything, Turbopack didn't support running custom transformers. So we're actually stuck on the last version we cut before deleting the next crates, running the transformers that exist in the turbopack repo. With the new support, we're almost back to the tip of main branch (there's still some snafu with `swc_core` upgrading that I'm working on).

navigations for the App Router, mirroring browser behavior.
- `#main-content` → scrolls to `id="main-content"` or

- `#top` → scrolls to the top of the page, this is a special case in
browsers.
- no hash → default scroll behavior, layout that changed

This moves the position of action handling so it can continue page
rendering afterwards. And a `asNotFound` option is added to
`LayoutRouter` to indicate the router to opt into the root not-found
boundary, so not found pages can be programmatically rendered instead of
relying on route mismatching (this is also needed by NEXT-463 later).
Fixes NEXT-467.

When `dynamicRouteTypes` or `staticRouteTypes` is empty, type `DynamicRoutes`/`StaticRoutes` fallbacks to type `string`, causing type `Route` to resolve to type `string` as well, meaning that the user can use any string as `href`. This fixes that by making those types fallback to type `never` instead, and if both `dynamicRouteTypes` and `staticRouteTypes` are empty, fallback to type `string`.

Not certainly sure about the reasonable limitation of this header. For example https://app-dir.vercel.app/context/books sends a state query of size ~110, consider an app with 100x more complicated nested, parallel and named segments, we still have a 3x extra room which should be enough.
Fixes NEXT-137.
This PR implements the route announcer for app directory. It almost uses
the same logic as the route announcer inside pages, with one notable
difference that the inner content node is now inside a shadow root. This
makes sure that it does as little impact as possible, to the
application. This is important as we no longer have the `__next`
wrapper.
Another thing worth mentioning is that the announced title is a global
singleton of the website. It shouldn't be affected by the concept of
layouts, but should be triggered when the router state (not just URL)
changes.

It will be crucial to detect these common problems and abort compilation, because it's intended to be using a server boundary but these problems might cause it ending up in the client.
Fixes NEXT-762.
This PR does two major changes:
1. Make sure both pages renderer and app renderer return `RenderResult`,
no more `null`. This was achieved with a new `null` type in the
constructor `new RenderResult(null)`, and a `.isNull()` method.
2. Remove all mutations of the `renderOpts` object inside renderers. To
pass extra information out, they need to be attached to the
`RenderResult` now. This also requires 1) to be done.
These changes are the initial steps to the isolated rendering worker
architecture. Besides those there're also some type improvements.
Fixes NEXT-807.

Fixes#39330.
I've not added a new test, but extended the existing test instead (and
re-enabled it).
It seems to me that a custom next/image config was not considered during
static generation (which itself uses `next export`?) before. Adding the
config to `renderOpts` in `packages/next/src/export/index.ts` resolves
the issue.
### Fixing a bug
When a timeout occurs the `handleDisconnect` can be called twice on my
machine (Chrome 110.0.5481.178). Once by the timeout code, and once by
the `onerror` handler, possibly triggered by the `source.close()` call.
This leads to every timeout triggering twice as many clients, which
quickly explodes to websocket reconnections spamming the network tab of
devtools. This trivial fix resolves the issue.

This is almost a rewrite of the transform to simply some logic. For a `"use server"` file we now simply annotate every exported identifier and will later do runtime checks. This is because that we can't statically know the source of exported values.
This rewrite also makes it possible to annotate anonymous arrow functions.

`mdx-bundler` is used for server-side transformation of MDX files and currently using it within server components will throw a `Module parse failed: Unexpected token` error.
Adding `serverComponentsExternalPackages: ['mdx-bundler']` to `next.config.js` fixes the issue, but it's probably good to add to the default exclusion list as `mdx-bundler` is a relatively popular approach for using MDX in Next.js apps.

transform stage. Mainly, `enable_typescript_transform` is now accepting
an option instead of boolean flag to down to
`EcmaInputTransform::Typescript`, and `get_*_module_context()` reads the
config value as needed.
Generate `/favicon.ico` route when favicon.ico is placed into `app/`.
Still collect favicon metadata image information through
metadata-image-loader but don't emit the file to static dist anymore.
Also collect favicon through metadata routes, and render it as static
routes. Also remove the `hash` we generated before, not needed anymore.
Change metadata static routes rendering process: collect static metadata
assets, read the buffer of the file data and return it in the response.
Closes NEXT-791
This PR adds basic support for default export of an async arrow
function:
```js
export default async (a, b) => { console.log(a, b) }
```
In upcoming PRs I'll refactor named export handling and inlined
declarations.
This PR adds Zod to the precompiled libraries, and use it to create schemas for the router state tree for validation. In other planned features/changes, Zod will also be used to do run-time data validation.
Fixes NEXT-135.
## Checklist
- [ ] Related issues linked using `fixes #number`
- no related issue exists, happy to open one if desired
- [x] Tests added
- not sure if specific tests are needed? there is an integration test
for environment variables, and Next.js relies a lot on passing
information through environment variables; i'd expect everything to
break if this change broke environment variable handling
- [x] Errors have a helpful link attached, see

- no new errors, does not apply
### What?
Re-assigning `process.env` substitutes the "magic object" that sets
environment variables at the process level with an ordinary JavaScript
object. This causes environment variables that are set after
`process.env` is re-assigned to not be visible to native add-ons.
See [this Node.js issue][issue] and [this reproduction case][repro] for
details.
[issue]: https://github.com/nodejs/node/issues/46996
[repro]: https://github.com/unflxw/nodejs-process-env-addons-repro
### Why?
In general, paraphrasing the maintainer in the Node.js issue,
re-assigning `process.env` is not a thing you should do. More
specifically, I'm trying to use Next.js' experimental OpenTelemetry
support with AppSignal's Node.js integration, which also uses
OpenTelemetry.
The AppSignal Node.js package sets environment variables in order to
configure a long-running process, which is then launched through a
native add-on. Because of the re-assignment of `process.env` that occurs
early in Next.js' lifecycle process, by the time the AppSignal Node.js
package sets environment variables, it's setting them in an ordinary
JavaScript object that Next.js left in the global `process` object, not
in the magic one created by the Node.js runtime.
This means that these environment variables are not _actually_ being set
for the process at the OS level, and therefore they're also not set for
the native add-on, or for the long-running process it spawns.
### How?
A `replaceProcessEnv` function is implemented that takes an environment
object as an argument, and applies the difference between that
environment object and the current environment to the existing
`process.env` object. This function is used instead of re-assigning
`process.env`.

### Description
Add more details to introspection and make it more robust to errors
during introspection
### Testing Instructions

This diff:
* introduces the `VersionedContentMerger` trait, which allows for
merging the updates of versioned contents within the same chunk group;
* implements this for `EcmascriptChunkContent`/`EcmascriptChunkUpdate`,
turning them into
`EcmascriptMergedChunkContent`/`EcmascriptMergedChunkUpdate`;
* creates a new `ChunkList` asset which is capable of merging chunk
updates of chunks within the same chunk group, and create such an asset
for dynamic chunks (through manifest/loader_item.rs) and chunk group
files assets.
This fixes a bunch of edge cases related to HMR:
* HMR of dynamic imports now works;
* Chunks getting added/deleted/renamed now also works with HMR, since
we're listening to updates at the chunk group level;
* CSS chunks get reloaded in the right order, with respect for
precedence.
There are still known edge cases with HMR:
* CSS chunks added through HMR are not inserted at the right position to
respect precedence (WEB-652).
* Update aggregation is disabled because we don't want a critical issue
to stop all HMR (WEB-582) . This would be fixed by applying aggregated
updates when dismissing the error modal, but there are some edge cases
with this too (e.g. what happens when an HMR update also causes an error
on top of an existing error).
Add support for cases like:
```js
const foo = async function () {}
export default foo
const bar = async function() {}
export { bar }
```
Also fix a bug where nested async function declarations are mistakenly
counted as actions.
Fixes NEXT-800.
