## What?
Fixes the condition being checked to match for Turbopack which always
adds the blur.
Webpack needed to lazy eval blur during `next dev` but Turbopack can
always blur since its much faster.
Closes NEXT-2259
## What?
Turbopack has the correct behavior of preferring `.ts` / `.tsx` for
first-party code. In Webpack we don't have a way to only resolve
`.ts`/`.tsx` in first-party code. Turbopack doesn't resolve `.ts`/`.tsx`
in `node_modules`.

## What?
`exportPathMap` didn't work when Turbopack was enabled because the
`serializeNextConfig` function mutates the original values, overriding
`exportPathMap`.
This PR changes the serialization to copy the object and mutate only the
copied object.
Also refactored the test that was checking `_next`, the better way to
test that is to have the page render something dynamically, which is
what is added in this PR.

# Turbopack

`styled-jsx` crate now has a hook to transform CSS code using a

### How?

Closes PACK-2256
formalizes the concept of dynamic APIs inside Next to allow for varying
semantics beyond just staticGenerationBailout.
### Dynamic APIs
#### `markCurrentScopeAsDynamic`
useful to bail out of default caching semantics but does not imply a
Request specific data source was read. critically, this semantic is
ignored if you are inside a cache scope
#### `trackDynamicDataAccessed`
Must be called before reading any data source that is derived from
Request specific data. Currently this is `cookies()`, `headers()`, and
`searchParams`. This kind of data access inside a cache scope is
forbidden (it always should have been, but now it will error).
#### `trackDynamicFetch`
This one is unideal but the complexity of patch-fetch's current
implementation necessitates it for now. Essentially it will postpone if
we are prerendering. Long term this should be eliminated with a refactor
of patch fetch.
### Other Improvements
Also removes the `staticGenerationBailout` implementation as it has been
replaced with more specific logic in the places it was previously being
used.
One area that has also been enhanced is the proxy for app-route modules.
Previously we proxied the Request every time however when we are doing
non-static generation executions we generally don't want the overhead of
wrapping the request. In the refactor here I also improved the runtime
performance by using static proxy handlers and I believe I also fixed a
few bugs related to `clone` and `url`
In general there has been a bit of refactoring to clarify how we should
handle various render/execution states and a reduction in implicit side
effects for proper execution.
Another callout to notice is that app-route modules do not attempt a
static generation if they are force-dynamic regardless of the PPR
setting. Previously the PPR setting would opt them into this code path
which is not necessary because PPR itself does not work for routes, only
pages.
Closes NEXT-2099
This PR adds a warning when attempting to optimize an animated image.
```jsx
<Image src="/image.gif" />
```
The warning looks like the following:
```
The requested resource "/image.gif" is an animated image so it will not be optimized. Consider adding the "unoptimized" property to the <Image>.
```
To remove the warning, add the `unoptimized` prop.
```jsx
<Image src="/image.gif" unoptimized />
```
We don't attempt to optimized animated images because it can be very
slow (30+ seconds) and sometimes deoptimizeds (the output is larger than
the input) so its best to serve the animated image as-is.
Closes NEXT-2199
## What?
There were a bunch of Sharp related tests failing when running the test
suite with Turbopack. The reason for this was that we automatically
detect the root of the project based on the closest lockfile (i.e.
package-lock.json). In this particular test a new package-lock.json was
added and since this suite is not yet isolated it cases problems.
This PR adds `outputFileTracingRoot` to explicitly provide the root of
the project, which ensures the right files are resolved.
Closes NEXT-2180
### 🧐 What's in there?
`config.analyticsId` is a rarely-used mechanism, initially intended to
Next.js users hosting their application themselves and willing to report
Core Web Vitals to Vercel Speed Insights.
This platform specific mechanism can be replaced with the built-in
[`useReportWebVitals`](https://nextjs.org/docs/app/api-reference/functions/use-report-web-vitals).
### 🧪 How to test?
1. make a new Next.js app
1. define env variable `VERCEL_ANALYTICS_ID` to a dummy value
1. start your application in dev mode:
```shell
⚠ config.analyticsId is deprecated and will be removed in next major

- Both the standalone server and the `startServer` function it calls
attempt to stop the server on `SIGINT` and `SIGTERM` in different ways.
This lets `server.js` yield to `startServer`
- The cleanup function in `startServer` was not waiting for the server
to close before calling `process.exit`. This lets it wait for any
in-flight requests to finish processing before exiting the process
- Sends `SIGKILL` to the child process in `next dev`, which should have
the same effect of immediately shutting down the server on `SIGTERM` or
`SIGINT`
fixes: #53661
refs: #59551
------
Previously #59551 attempted to fix#53661, but had broken some tests in
the process. It looks like the final commit was also missing an intended
change to `utils.ts`. This should fix those issues as well as introduce
a new set of tests for the graceful shutdown feature.
In the last PR I was squashing and force-pushing updates along the way
but it made it difficult to track the changes. This time I'm pushing
quite a few commits to make it easier to track the changes and refactors
I've made, with the idea that this should be squashed before being
merged.

## What?
While working on some other refactors I noticed that this check for
duplicate routes is incorrect.
Upon further investigation with @feedthejim we noticed that this check
can be removed altogether as it's already being checked correctly in the
route matcher.
I've moved the test to use `createNextDescribe` and removed the check
for build because it's a dev-only warning.

Closes NEXT-1941
Passing `NODE_OPTIONS='--inspect'` was failing because a sub-process was
getting created (`getRegistry()`) which would trigger a "address already
in use" error when the process inherited the same debugger port from the
parent process.
I had to disable this test in
https://github.com/vercel/next.js/pull/59508 because it wasn't passing,
CI was just skipping it. This PR fixes the behavior and re-enables the
test.
Fixes#55862
Closes NEXT-1854
This was incorrectly setting the upper bound on the `--group` argument
to our test runners (ie, `11/122`), which was causing a lot of tests to
be missed.
Closes NEXT-1851
Fixes ability to run `NODE_OPTIONS='--inspect' next dev` as described in

This bug seem to have been introduced in

Closes NEXT-1791
### What?
In #57062, a deprecation warning was added for usage of `nextConfig.images.domains`. This warning was erroneously showing up for users that had an `assetPrefix` configured.
### Why?
When an `assetPrefix` specified, during assignment for `nextConfig` default values, we push to `nextConfig.images.domains` so that the user doesn't receive errors about hostnames not being configured ([Original PR](https://github.com/vercel/next.js/pull/29307)). This means people are indirectly being opted into a deprecated config, and receiving a warning because of it.
### How?
We no longer push any defaults to the deprecated config option. Additionally, this applies the same defaults handling to `remotePatterns,` as otherwise people using this new config will run into the same issue as this block was originally intended to fix.
Fixes#58074
This PR fixes a bug where Next.js would not use the serverComponentsExternalPackages config when opting into the `experimental.bundlePagesExternals` flag.
The fix consists of just adding a check for the externals config.
This PR enables the `experimental.webpackBuildWorker` to be on by
default. This flag enables logic inside Next.js to run the compilation
in an isolated worker. The reason for this is that the webpack
compilation process retains a lot of memory for the whole duration of
the build process because it uses some packages that leak. We don't need
it for the rest of the process so it's best to use it in a worker and
leave the memory to be used for static generation.
This will improve memory usage during build, avoiding OOMs caused by
webpack exceeding memory.

Do not log the removed experiments in the start server logs, for instance `experimental.appDir` should get warned as unexpected option but it's not the valid experiment anymore
This doesn't need to error, we can instead warn that the functionality will not work as expected out of the box. Support can be added for outside of Next for this to behave as expected.
These are supported when deployed via the Nextjs builder ([x-ref](https://github.com/vercel/vercel/blob/main/packages/next/src/index.ts#L851-L855)).
BREAKING CHANGE
Since `next export` has been printing a deprecation warning since https://github.com/vercel/next.js/pull/47376, its safe to remove in semver-major.
The upgrade path is to simply add `output: 'export'` in `next.config.js` - everything will continue to work the same.
This config greatly improves the `next dev` experience today. And in the future, it will improve performance of `next build` because we no longer need to do two passes (build then export).
### What?
* no need to clear require cache when assets where not used previously
* make build status reporting more consistent
* report build status to client side for build indicator
### Why?
### How?
Closes WEB-1826
This:
- Uses `isServer` to use the appropriate Turbopack `FileSystem` when
creating `FileSystemPath`s
- Properly uri decodes path segments originating from `file://` uris
- Correctly reads chunks starting at the project path instead of the
root path
Closes WEB-1815

The asset context is a better place to store the layer, because it's
affected by transitions unlike the chunking context
This PR also removes a bunch of unused code
### Why?
See https://github.com/vercel/turbo/pull/6237 for the rationale
Also needs to wait for that PR to be merged
Closes NEXT-1814

This avoids testing against latest exact canary version as this causes these tests to fail while the publish is still in progress. As a follow-up we can investigate moving this post publish or packing/deploying tarballs to use.

## History
We used to pass `onLoad` through directly to the underlying img so `onLoadingComplete` was introduced in order to handle the case when `placeholder="blur"` was used and `onLoad` would trigger before the placeholder was removed.
We have since changed the behavior of `onLoad` so that it acts the same as `onLoadingComplete` and therefore `onLoadingComplete` is no longer needed.
## What is this PR doing?
This PR marks `onLoadingComplete` as deprecated in favor of `onLoad`. In the future, we may remove `onLoadingComplete`.
I think some of the runners are missing `yarn` globally installed so its attempting to install with corepack. But the default behavior of corepack is to use the repo version (pnpm in this case) so running `yarn` will error. This PR disables corepack strict mode to avoid that problem.
Looked for `webpack(config` in the test suites and disabled the ones that are testing webpack specifically. There are a few more that are not skipped as they should be implemented for Turbopack.
Closes WEB-1702
This PR implements initial support for the `next/dynamic` in Turbopack,
more specifically resolving some hydration errors and other components
boot up cases.
Previously, turbopack had partial next/dynamic support via its own mode
(https://github.com/vercel/next.js/pull/56389/files#diff-e1af4f79cb88a73f819a25443d15ed4b1ffabcbb879256caa59b751fad46d7c4L68),
which does a transform against `next/dynamic` wrapped import to embed
dynamically resolvable chunk ids like
(ad42b610c2/packages/next-swc/crates/next-transform-dynamic/tests/fixture/wrapped-import/output-turbo-dev-server.js).
However, since next.js relies on static path to the chunks to the
dynamic import and passing those ids in between client-server to ensure
component load (and avoid hydration errors), it doesn't work out of the
box. This PR changes turbopack's behavior to closely mimic what current
next.js's webpack plugin does, by
1. Traverse the module graph, find out `dynamic(import())`
2. Generate chunks for those imports, creates a partial LoadableManifest
per each imports
3. Merge partial manifest into a single `react-loadable-manifest.json`
4. For the id, use static (Webpack mode) instead of dynamic so we can
embed it in `react-loadable-manifest` as well as next.js can use it to
pass it between server-client context.
I left a small comment to the implementation
(https://github.com/vercel/next.js/pull/56389/files#diff-bf12ed2c69d0bc89a06884779da4ae44967eb8becada031dea12bedef28e2622R155)
for the lifecycle of this feature in case to fix further.
This makes to pass most of the basic next-dynamic related integration
tests, except if the import have webpack specific features like
ad42b610c2/test/development/basic/next-dynamic/pages/dynamic/multiple-modules.js (L5).

this is a follow-up to #48018 (don't add `isolatedModules: true` to
`tsconfig.json` when `verbatimModuleSyntax: true` is set), which also
handles the case where `verbatimModuleSyntax: true` is set in a base
tsconfig which is being referenced via `tsconfig#extends`.

This adds a test that asserts that, without additional configuration like `experimental.bundlePagesExternals`, Next.js does not bundle `node_modules` for pages.
Closes WEB-1708
The PR supersedes the https://github.com/vercel/next.js/pull/53150, which is way too outdated, has way too many conflicts, and also heavily relies on GitHub Copilot (which makes the progress slow and tedious).
The PR uses [`json-schema-to-zod`](https://github.com/StefanTerdell/json-schema-to-zod) (instead of the GitHub Copilot) to generate the zod schema, and manually replaces all generated `z.customRefine` with my hand-written zod schema.
TODO:
- [x] Convert schema
- [x] Reduce `z.any()` usage
- [x] Create human-readable errors from the `ZodError`
- [x] Update test cases to reflect the latest error message
-----
The benefit of using zod over ajv:
- Easier maintenance: zod schema is straightforward to compose.
- Better typescript support: config schema now strictly reflects the `NextConfig` type.
- Smaller installation size: by replacing `ajv` and `@segment/ajv-human-errors` w/ `zod`, I am able to reduce installation size by 114 KiB.
- Better Extension: the zod error message is easy to customize.
-----
In the previous PR https://github.com/vercel/next.js/pull/56083, @feedthejim replaces `zod` w/ `superstruct`. `superstruct` is lightweight and fast, which makes it perfect for creating simple schemas for RSC payload. But, this also means `superstruct` has its limitations compared to `zod`:
- `superstruct`'s syntax is different, and some utilities's usage is counter-intuitive:
- `z.array(z.string()).gt(1)` vs `s.size(s.array(s.string()), 1)`
- `z.numer().gt(1)` vs `s.size(s.number(), 1)`, `s.min(s.number(), 1)`
- `z.boolean().optional().nullable()` vs `s.nullable(s.optional(z.boolean()))`
- `superstruct` has weaker TypeScript support and worse DX compared to `zod` when composing huge schema:
- `zod.ZodType + z.object()` can provide a more detailed type mismatch message on which specific property is the culprit, while `Describe + s.object()` provides almost no information at all.
- `zod`'s schema is more powerful
- `z.function()` supports `z.args()` and `z.returns()`, while `superstruct` only has `s.func()`
- zod also has Promise type `z.promise()` and intersection type `z.and()`
- `superstruct`'s error is harder to parse compared to `zod`'s `ZodError`
So in the PR, I re-introduced `zod` for `next.config.js` validation.
Reland #54403
Also modifies the implementation of #55950 to not change the prefetch behavior when there is flight router state - we should only check the entire loader tree in the static prefetch case, otherwise we're inadvertently rendering the component tree for prefetches that match the current flight router state segment. ([slack x-ref](https://vercel.slack.com/archives/C03S8ED1DKM/p1695862974745849))
This includes a few other misc fixes for static prefetch generation:
- `next start` was not serving them (which also meant tests weren't catching a few small bugs)
- the router cache key casing can differ between build and runtime, resulting in a bad cache lookup which results suspending indefinitely during navigation
- We cannot generate static prefetches for pages that opt into `searchParams`, as the prefetch response won't have the right cache key in the RSC payload
- Layouts that use headers/cookies shouldn't use a static prefetch because it can result in unexpected behavior (ie, being redirected to a login page, if the prefetch contains redirect logic for unauthed users)
