This PR adds a new marker for intercepting siblings routes + adds some
validation to intercepting routes ( you shouldn't use (..) at the top
level!)
also fixes a bug with any interception from `/` when navigating from a
child route
the new marker, `(.)`, makes it easier to model cases like
```
/profile/[id]
/profile/[id]/photos/[id]/
```
With the current syntax available, you’d need to do:
```with (..):
/profile/[id]/(..)[id]/photos/[id]
with (...):
/profile/[id]/(...)profile/[id]/photos/[id]
with (..)(..):
/profile/[id]/(..)(..)profile/[id]/photos/[id]
```
now, with (.)
```
/profile/[id]/(.)photos/[id]
```

This PR basically adds support for processing multiple router payloads.
Previously we were only handling one payload at a time but now that we
introduced parallel routes, we need to be able to render and return
separate parts of the layout separately.
Before, the single payload was generated in a DFS manner: we traversed
the router state and rendered the first segment of the tree that we
found needed rendering. In practice, this meant that we could miss
adjacent segments that might need to be re-rendered as well.
Now, we iterate all branches of the tree and return an array of flight
patches to be applied on the client correctly.

For now, this isn't a strong requirement as normal `fetch` requests will
still work with `react@next`. But in the future, form related props e.g.
`action=` and `formAction=` requires the experimental build.
Fixes NEXT-954.
Reverts vercel/next.js#48038
fix NEXT-926
---
The root cause was that when copying the package.json, I removed all
fields except for a few (such as `exports`) but missed the `browser`
field. That caused the client bundle to resolve to the Node.js version
of React DOM, and then we had the `async_hooks` error. Added it back in
99c9b9e51f8b0d4e4503ece9d07bce09161f3341.
I reproduced the error with next-site earlier and confirmed that this
fix is good.
### What?
Our current logic of detecting if a route allows dynamic params or not
(`fallback`) is flawed, and this PR fixes it.
### Why?
Right now, if no `generateStaticParams` is specified we return
`fallback: undefined` during dev. However, for an app with multiple
params, it may have multiple `generateStaticParams` defined in different
levels. If some level isn't covered by any `generateStaticParams`, we
still can't determine the fallback value.
### How?
I added a naive implementation to check if all params are covered by
`generateStaticParams` in the current or inner layers.
Closes NEXT-946
### What?
This PR makes the parent layout of parallel routes re-render when the
parallel route segments are different or when either of them has a
refetch marker.
Example:
```
.
└── app/
├── page.ts
├── layout.ts
├── foo/
│ └── page.ts
└── @modal/
├── default.js
└── foo/
└── page.ts
```
Here if you navigated to `/foo` from `/`, `@modal/foo/page` would never
get re-rendered because the tree would only re-render from
`foo/page.ts`.
This PR adds a check that checks the router state on navigation to see
if the parallel route segments diverge on navigation. Here we would be
checking that `@modal/default` is different from `@modal/page` so we
would re-render.
Also added some logic to make sure that refetch routes are processed
first when handling parallel routes.
### Why?
See example
Closes NEXT-966

x-ref: https://github.com/vercel/next.js/pull/47930
The first implementation had limitation wrt to static routes so this is
a "simpler" approach to making interception work. This also fixes a few
bugs.
In this PR:
- changed the computation of the referrer route to now live on the
client state, since it's the only place where you can accurately keep
track of that. One router state was not sufficient, we needed a delta of
two states to guess which route had changed when having parallel routes
in the tree.
- uses rewrites as the basis for interception now instead of route
handlers, this means that we have to do some sketchy logic to make the
rules work since they only handle regexes whereas we have
`path/like/[this]`
- dev server now reloads rewrites as well when needed

### What
This issue is introduced in #47688, we need to do the same work for
rendering single component which collecting the assets and then render
with root layout + root not found
Fix#47970
Related #47862 (partially fix the css issue but not link issue)
### How
This PR encapsulates the preload and stylesheets assets collection and
rendering process, and move them into a helper, and share between the
component rendering and the root not found rendering
This pull request extends the type checking functionality of the
`typedRoutes` feature, which is currently available in the `<Link
href={Route}>` component, to the following `router` APIs:
`router.push()`, `router.prefetch()`, and `router.replace()`. The
implementation leverages the existing work done for the `<Link>`
component, allowing for a straightforward integration of type checking
into the aforementioned `router` APIs.
fix NEXT-501
### What
When using dynamic metadata image rouets (such as `opengraph-image.js`)
under group routes, the generated urls were still normalized. In this
case it might have conflicts with those ones not under group routes. For
instance `app/(post)/opengraph-image.js` could have same url with
`/app/opengraph-image.js`. In reality we want them to be different
route, unlike layout or pages.
### How
So when we found `()` or `@` signs from the metadata image urls, we'll
generate a unqiue suffix (`-\d{6}`) and append to the generated url. So
they can be isolated from the ones are not under special convention
routes.
Closes NEXT-937
For twitter and og image nested properties we should render them as
snake case according to [og spec](https://ogp.me/) and [twitter card
docs](https://developer.twitter.com/en/docs/twitter-for-websites/cards/guides/getting-started).
For typing we keep them as camel case and then convert them to snake
case during render
This issue is reported in #47960 that user thinks the types are
incorrect, but turns out twitter metadata didn't render it correctly
Closes#47960
This ensures we prefix the dynamic route params in the query so that
they can be kept separate from actual query params from the initial
request.

When `metadataBase` is missing and used for resolving og/tw image urls,
we'll fallback to localhost for it to always safely resolve the url
instead of erroring. Instead, we give a warning in console for which url
is resolved but with fallback `metadataBase`.
Once they found the warning and it's not expected, they need to update
the `metadataBase` to a proper URL for giving the right domain.
Another minor change is always resolve canonical with current pathname
if it's a URL instance.
Remove `resolveStringUrl` as it's not required anymore, the default
`pathname` for `resolveUrl` is '', so no trailing slash needs to be
removed
Next.js includes various feature sets that depend on specific release
channels of React. However, our current setup only includes the `next`
channel of React, which restricts our ability to integrate with features
available on the `experimental` channel.
To address this limitation, this pull request introduces the following
changes:
- Vendors the `react@experimental` version, along with the corresponding
`react-dom` and `scheduler` packages.
- Modifies the `sync-react` script to also update the `experimental`
channel and removes `--version` as they're always synced to the latest
now.
- Retains the default behavior of using the `next` channel in the
`appDir` directory.
- Adds an option to switch to the `experimental` channel by setting
`experimental.experimentalReact: true` in the configuration.
fix NEXT-926 ([link](https://linear.app/vercel/issue/NEXT-926))
### What?
Took a bit to investigate this one, eventually found that the case where
it broke is this one:
```
app
├── [slug] // This matches `/blog`
│ └── page.js
└── blog
└── [name] // This matches `/blog/a-post`
└── page.js
```
The router cache key is based on the "static key" / "dynamic parameter
value" in the tree. This means that the cache key for `/blog` that
matches `/[slug]` would be the same as the static segment `blog`. This
caused the cache to become intertwined between those paths, it's
accidental that the router got stuck in that case, main reason it got
stuck is that the fetch for the RSC payload returned a deeper value than
expected. In `walkAddRefetch` we bailed because that walked the
`segmentPath` didn't match up.
The underlying problem with this was that the render would override the
cache nodes incorrectly. This would also cause wrong behavior, even
though that wasn't reported. E.g. `app/[slug]/layout.js` would apply on
`app/blog/[name]/page.js` because they'd share the `blog` cache node.
### How?
This PR changes the cache key to include the dynamic parameter name and
type, e.g. the dynamic segment `['slug', 'blog', 'd']` previously turned
into `'blog'` as the cache key, with these changes it turns into
`'slug|blog|d'`. For static segments like `blog` in `app/blog/[name]`
the key is still just `'blog'`.
I've also refactored the cases where we read the segment as the code was
duplicated in a few places.

This PR implements the route intercepting feature from [the layouts
RFC](https://nextjs.org/blog/layouts-rfc#intercepting-routes).
You can use route interception by adding these special markers,
`(..),(...) or (..)(..)` to your segment definition, i.e. by creating a
page with this path: `/foo/bar/(..)baz/page.ts`.
Changes in this PR:
- added a new kind of route handlers to support intercepting routes
- added a "referrer" concept that is derived from the client router
state on navigation, where we try to guess which URL you were on before
- added some units tests
- updated the renderer to allow for overrides when the path params don't
include the current dynamic param, so we rely on the passed router state
to create it

Closes NEXT-931
Should fill dynamic routes url with params when generate the metadata
image urls.
For `/(group)`, we need to normalize the path first;
For dynamic routes `/[slug]`, we need to fill the params.
Change the image module from `() => image` to `(prop) => image(proop)`
so we can fill the runtime `params` into url
Closes NEXT-932
---------
This updates to have a separate routing process and separate rendering
processes for `pages` and `app` so that we can properly isolate the two
since they rely on different react versions.
Besides allowing the above mentioned isolation this also helps us
control recovering from process crashes easier as pieces are more
isolated from one another e.g. an infinite loop during rendering will no
longer block the compiler and can be stopped/restarted as needed.
In follow-up PRs we will continue to separate out the routing logic from
the rendering logic so that each process only loads what is relevant to
it helping simplify the flow for requests regardless of type.

### What / why?
Currently there is a bug because the `subTreeData` can only be applied
once, however, we reuse the same response when a url was prefetched.
During the first render of the response we apply the cacheNodes and then
these should be reused for subsequent navigations. There's currently a
bug because `fillLazyItemsTillLeafWithHead` creates `LAZY_INITIALIZED`
cache nodes that don't copy the previous cache node `parallelRoutes` and
`subTreeData` value, causing the cache nodes below where the
`subTreeData` is applied to be deleted from the cache, even when they're
not affected by the navigation.
### How?
This PR adds copying of the cache node when it exists already, I've
added a marker for `wasPrefetched` to trigger that behavior but in
talking to @feedthejim about this it seems we can swap to this behavior
always when applying the server response, that needs to be discussed
further though, this is temporary implementation with the fix for routes
that were prefetched.
