Fixed issue where `require` will return a Promise if (and only if) there
is an ESM module imported in `instrumentation.ts`:
61cd219f15/packages/next/src/server/next-server.ts (L212)
Had to move stuff to async function from constructor, but luckily we
already have `prepare`.
### What / Why / How?
In a project with `"type": "module"` in `package.json` and a `compilerOptions.moduleResolution` of `Node16` or `NodeNext` in `tsconfig.json`, running `tsc` will yield errors like the following:
```
.next/types/app/[...not_found]/page.ts:1:40 - error TS2307: Cannot find module 'next/dist/lib/metadata/types/metadata-interface' or its corresponding type declarations.
1 import type { ResolvingMetadata } from 'next/dist/lib/metadata/types/metadata-interface';
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
.next/types/app/layout.ts:2:24 - error TS2835: Relative import paths need explicit file extensions in EcmaScript imports when '--moduleResolution' is 'node16' or 'nodenext'. Did you mean '../../../app/layout.jsx'?
2 import * as entry from '../../../app/layout'
~~~~~~~~~~~~~~~~~~~~~
.next/types/app/layout.ts:3:40 - error TS2307: Cannot find module 'next/dist/lib/metadata/types/metadata-interface' or its corresponding type declarations.
3 import type { ResolvingMetadata } from 'next/dist/lib/metadata/types/metadata-interface'
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
```
These files are checked because of the following `tsconfig.json` line which Next.js adds:
```diff
{
"include": [
+ ".next/types/**/*.ts",
]
}
```
Adding the extensions will make it work with these projects and still maintain backwards compatibility with other TypeScript / module configurations.
### What?
This PR vendors @vercel/og and export `ImageResponse` from
`next/server`. When you render a opengraph image the below code snippets
will be legit:
```tsx
import { ImageResponse } from 'next/server'
export default function og() {
return new ImageResponse(<div style={{ width: '100%', height: '100%' }}>hello</div>)
}
```
### Why?
To make development more easier, user can directly use `@vercel/og`
Image Response with nextjs instead of install it and use it. This makes
building metadata icons, og or twitter images more convenient.
### How?
Closes NEXT-899

This PR refactors imports to turbopack to turbo-binding, as same as we
used to do with next-binding. Current next-binding in this repo doesn't
make sense anymore and removed. There are no functional changes. This'll
reducwe surface for the imports and also will make easier to run
integration test over latest turbopack.
Note swc dependency is not reflected in this PR yet - following PR will
update those imports.

### What?
This PR fixes the issue where `next-types-plugin`'s typeguard files include unused imports, which was introduced by #47185 and might be problematic with certain configuration.
### Why?
We don't need `ResolvingMetadata` when `options.type` is `'route'` and `NextRequest` when `options.type` is `'page'`/`'layout'`, and so caused the issue.
### How?
Simply check whether `options.type` is `'route'` or `'page'`/`'layout'`.
Fixes#47646
This PR removes usage of `appPaths` in favor of `hasAppDir` to avoid the
issue where export does not read app manifest.
Fixes the error:
```
TypeError: Cannot read properties of undefined (reading 'cssModules')
```
fix NEXT-885 ([link](https://linear.app/vercel/issue/NEXT-885))
Previously the app route handler was included in the server bundle, and called into user code to execute the underlying handler logic. This PR serves to move the handler code into the bundle so that the Node.js environment more closely matches the Edge environment.
This also updates the Rust code for the new loader.
fix NEXT-712 ([link](https://linear.app/vercel/issue/NEXT-712))
### What?
- Besides existing `Metadata` type, expose `ResolvingMetadata` and `ResolvedMetadata` to `'next'`.
- Group `Robots` / `Sitemap` / `Manifest` these dynamic data routes types as `MetadataRoute` type and expose to `'next'`
### Why?
Allow users to type the more API easily, and grouping them to avoid type conflicts (e.g. we have `Robots` in metadata interface field, `MetadataRoute.Robots` can avoid conflicts)
### How?
Closes NEXT-908
### What?
Fix robots.txt generation
### Why?
Should support multiple allow/disallow rules, they should be generated in different lines
### How?
Closes NEXT-905
Fixes#47224
fix NEXT-905 ([link](https://linear.app/vercel/issue/NEXT-905))
In #47328 we made the root level `/not-found.js` a special entry, to
override the page 404 during builds. However, it's possible that the
user has a valid `/not-found/page.js` route that might conflict with
this special entry. This PR changes the entry to be `/_not-found` so it
will never conflict with existing valid entries.
Previously the app route handler was included in the server bundle, and
called into user code to execute the underlying handler logic. This PR
serves to move the handler code into the bundle so that the Node.js
environment more closely matches the Edge environment.
fix NEXT-712 ([link](https://linear.app/vercel/issue/NEXT-712))
Previously to this PR, if an absolute path contained an `_` it would
ignore all app files. If for example the Next.js app was in a folder
named `/some/_directory` then today:
```
/some/_directory/app/page.js <- should 200, currently 404
/some/_directory/app/route.js <- should 200, currently 404
/some/_directory/app/_internal/route.js <- should 404, currently 200 in development
```
This also enables the same `_` functionality for app routes in
development. After this PR, we get:
```
/some/_directory/app/page.js <- 200
/some/_directory/app/route.js <- 200
/some/_directory/app/_internal/route.js <- 404
```
Adding OpenBSD and NetBSD platforms
Fixes: #44058
Probably needs more review I tried compiling the codebase as instructed
with pnpm
[here](https://github.com/dante-robinson/next.js/blob/canary/contributing/core/developing.md),
but turbo (a dependency of pnpm) has no BSD binary so I can't compile
the code on OpenBSD to test it however @gjskha mentioned in the issue he
added openbsd as a platform to get it working so in theory this change
should work and shouldn't break anything.

Currently in a client boundary file, we only explicitly export
individual fields in ESM (`export foo`) when the source type is
`module`. However in most of the time SWC gives the `auto` source type.
This PR improves the type detection a bit so if it's `auto` and we do
see ESM exports collected, we assume it's ESM and re-export these
fields.

Previously `next-swc` had relay transform inline, but it makes
maintenance harder. So this PR patches next-swc to use relay plugin from
`swc-project/plugins` repository.
Closes WEB-782
Fixes#47239
fix NEXT-883 ([link](https://linear.app/vercel/issue/NEXT-883))
### What?
Adds a warning when `useSearchParams` deopts the entire page to
client-side rendering.
When there is no Suspense boundary the entire page becomes client-side
rendered, you can learn more about that here:
https://beta.nextjs.org/docs/api-reference/use-search-params#static-rendering
### Why?
We've seen a few cases where people accidentally deopt the entire page
by calling `useSearchParams` as there was no indicator that this deopt
happened.
### How?
When the full page deopt happens the error is caught by the rendering
code so we warn there.
Closes NEXT-589

### What?
This PR adds next-types-plugin's support for Route Handlers.
### Why?
Since `route.js` is somewhat like `page.js` and `layout.js`, I find it to be necessary that we also enable TS checks for these files as well.
### How?
Just changing the `createTypeGuardFile` function a bit and adding a few new tests, yeah.
More cleanup flowing out of the removal of the `target` option.

### What?
Ensures `useParams` can be called in `pages`. In that case it returns
`null` similar to other navigation hooks that can't be backported.
### Why?
When migrating you can have components that are rendered in both `app`
and `pages`.
### How?
Uses the same approach as `useSearchParams` and `usePathname`. Type is
added to `navigation.d.ts` that overrides `next/navigation` only when
`pages` exist, that way applications built entirely on `app` don't get
the `null` type.

### What?
Removes `head.js` file convention in favor of built-in SEO support through `metadata`: https://beta.nextjs.org/docs/guides/seo

This PR is another part of making parallel routes viable!
- enables some of the tests, partially only in dev (build fails because
the intersection routes are not implemented)
- introduces a new type of special file: a `default` file that can be
added to any segment, next to `page` etc, that will act as the
default/placeholder when a layout does not match

Fixes issue with app directory that caused problems with `i18n` was
enabled. Previously, when you accessed a URL like `/blog/first-issue`,
you would expect it to hit the app route at `/app/blog/[slug]/page.tsx`,
but instead it internally attempted to access
`/app/{defaultLocale}/blog/[slug]/page.tsx` (where `{defaultLocale}` is
set in `next.config.js` via `i18n.defaultLocale`). This is because while
the path did not assume the locale, the domain/default was enough to
suggest it, causing the mismatch.
This adds a new internal parameter for tracking this _default_
assignment so it can be handled by the matcher correctly.

Revert some code in #47379 and finalize HOC support. We should require
the HOC to return a "use server" function, so there's no need to compile
the function call specially now.
To make that wrapping logic work, we need to allow passing a server
reference to another server reference. This usually happens in the
function closure in the HOC case, but ideally it's also allowed to
directly pass it as an argument. This requires adding React server DOM's
`encodeReply` and `decodeReply` and other corresponding changes,
including adding `busboy` (can probably be vendored?) as we need to
parse the multipart body now.
fix NEXT-808 ([link](https://linear.app/vercel/issue/NEXT-808))
([link](https://linear.app/vercel/issue/NEXT-808))
### What?
In `app` all directories starting with `_` are now considered private
and won't be routed.
E.g. `app/_components/page.js` -> does not route
If you want to have a route starting with an underscore like
`/_settings` you can use `%5F` which is the url encode version of `_`:
`app/%5Fsettings/page.js`-> does route
### Why?
Ensures that you can create directories that will never conflict with
Next.js internal naming. E.g. when additional conventions are added for
file names.
### How?
It's a bit more involved than you might expected:
- build
- While resolving entries by traversing `app` parts with `_` are ignored
- While normalizing entires `%5F` is replaced with `_`
- I've changed one case that was relying on the entry name for resolving
to use the full path to the file instead.
- dev
- Ignored paths with underscore from being generated as part of the
initial scan of the filesystem
- Updated development and production the route matcher to replace `%5F`
with `_` so that it matches the right path.

### What?

### Why?
next.js users who use [Axiom](https://axiom.co) has been [asking](https://github.com/axiomhq/next-axiom/issues/109) for this feature for nextjs 13, as it was working for nextjs 12.
This ensures we only honor cache entries from the in memory cache for up
to 2 seconds so that revalidates can correctly propagate and also
increases max fetch cache entry size to 2 MB. The `fetchCache` export is
also being detected in this PR but not yet honored which will be done in
a follow-up.
