We currently don't make it obvious when next export is being leveraged
and middleware is present which won't work when deployed to a static
host so this ensures we warn the same way we do for API routes.

This option was initialial added in #8378.
This pr removes `config.experimental.profiling` since this option is no

Fixes handling in isolated tests for windows and adds initial setup to run the main `app-dir` test suite. Also adds retrying when fetching test timings fails due to rate limiting.
Closes: https://github.com/vercel/next.js/pull/44331
The default behavior for svg is `dangerouslyAllowSVG: false` which means we won't try to optimize the image because its vector (see #34431 for more).
However, svg was incorrectly getting the `srcset` attribute assigned which would contain duplicate information like:
```
/test.svg 1x, /test.svg 2x
```
So this PR makes sure we treat svg the same as `unoptimized: true`, meaning there is no `srcset` generated. Note that this PR won't change the behavior if `loader` is defined or if `dangerouslyAllowSVG: true`.
This fixes a bug where next.config.js was configured with `images.unoptimzed: true` but the Image Optimization API was not truly disabled. Since there is no way to override the config at the component level, its safe to say the API can be disabled.
# Reverts vercel/next.js#43587
PR #43587 breaks the `placeholder="blur"` property on the `<Image />`
component by keeping the `blurStyles`, e.g. the blurred image, after the
image is loaded.
**This regression does _not_ introduce any breaking changes or bugs.**
---
The reason for the original PR was:
> This PR remove `React.useState()` from the `next/image` component. It
was only used in the `onError` case and it was causing Safari to become
very slow when there were many images on the same page. We were seeing
1s delay blocking the main thread when there were about 350 images on
the same page. Chrome and Firefox were not slow.
The original PR is a performance improvement for Safari on a corner
case.
Additionally, when tackling this performance improvement again, the
`blurStyle` needs to know when the the image is done loading so it can
get rid of the blur. The state is updated in `handeLoading()` and isn't
just used `onError`.
## Fixes issues
- Fixes#43829
- Fixes#43689
## To reproduce
For reference this when #43587 was pulled into Next.js
[v13.0.6-canary.3](https://github.com/vercel/next.js/blob/v13.0.6-canary.3/packages/next/client/image.tsx)
- Regress the `image.tsx` to
[v13.0.6-canary.2](https://github.com/vercel/next.js/blob/v13.0.6-canary.2/packages/next/client/image.tsx)
- Do a local build with the regressed `image.tsx` on (current canary
build)
[v13.0.8-canary.0](https://github.com/vercel/next.js/releases/tag/v13.0.8-canary.0)
- Example code, (import any image you like) make sure to use
`placeholder="blur"`
```typescript
import Image from 'next/image'
import CatImage from '../public/cat.png'
<Image
src={CatImage}
width={500}
height={500}
alt="Cat"
priority
placeholder="blur"
/>
```
- Image will still have the blur after the image is loaded
- Before and after screenshot

### Summary
Migrate `next/dynamic` to implementation based on `React.lazy` and
`Suspense`. Then it becomes easier to migrate the existing code in pages
to layouts. Then we can support both `ssr` and `loading` option for
`next/dynamic`.
For `loading` option, it will work like `Suspense`'s `fallback` property
```js
<Suspense fallback={loading}>
<DynamicComponent />
</Suspense>
```
For `ssr` option, by default `React.lazy` supports SSR, but we'll
disable the `ssr: false` case for dynamic import in server components
since there's no client side involved.
Then we don't need `suspense` option anymore as react >= 18 is always
required. Mark it as deprecated.
It also supports to load client component dynamically in server
components now.
#### Code code changes
* switch loadable component to `lazy` + `Suspense`
* will make sure it's retuning a module from `loader()` to
`loader().then(mod => ({ default: mod.default || mod }))` since `lazy()`
only accepts loader returning a module
* Inside suspense boundary, throwing an error for ssr: false, catch the
error on server and client side and ignore it.
* Ignore options like ssr: false for server components since they're on
server, doesn't make sense
* Remove legacy dynamic related transform
#### Feature changes
* `next/dynamic` will work in the same way across the board (appDir and
pages)
* For the throwing error, will make it become a API that throws error
later in the future, so users can customize more with `Suspense`
* You can load client components now in server components with dynamic.
Resolves#43147
#### Tests
* existing dynamic tests all work
* add case: import client component and load through next/dynamic in
server components
### Issues
Updates our test config to take advantage of more concurrency and also
updates to leverage the playwright docker image to reduce flakes from
actions/setup-node stalling or playwright dependencies stalling on `apt
install`.
This reduces our test times from upwards of 30 minutes down to back
around 15 minutes.
Fixes pnpm w/ example being the only test outside the test suite.

In #41548, I show that I would like to provide an object with images in
getStaticProps. The StaticImageData is parsed correctly and provided as
a prop to the page. Nonetheless, the image is not available in the
static directory. Therefore the image is not shown. This is also
addressed in issue #29571. The underlying cause is that the import of
the image is removed from the client bundle and only present in the
server bundle.
Evaluating the next-image-loader shows that the file is only placed in
the static directory if emitted from the client bundle by firing
this.emitFile. By changing this to only emitting the file from the
serverside bundle in the webpackloader, static images loaded in the
getStaticProps are made available properly as well as images directly
used in componts (so present in server and client bundle).
This would PR would prevent the circumventing solution which enforces
that the StaticImageData should be present in the client side bundle
while it will also be present in the staticprops.

This adds a new `experimental.middlewarePrefetch` config with two modes
with the default being the `flexible` config.
- `strict` only prefetches when the `href` explicitly matches an SSG
route (won't prefetch for middleware rewrite usage unless manual
`href`/`as` values are used)
- `flexible` always prefetches ensuring middleware rewrite usage is
handled and also prevents executing SSR routes during prefetch to avoid
unexpected invocations

**I'm not sure if this is legit to fix, shared context below**
This PR attempts to fix test fixtures to reflect test failures. On my
working branch has unrelated changes to `next-env.d.ts` declaration. I
started to seeing intermittent test failures on CI, as well as local. It
was nearly 100% reproducible on local, while on CI it was nearly not
reproducible but only appears intermittently.
Some code archaeology leads me to this PR
https://github.com/vercel/next.js/pull/28316, specifically
77150dac79 (diff-9495c8b2cd0a5f2c471a37c24eac56caba4bd5cf95e2d021f95c4718e3191b47L33)
seems implying test fixture need to be updated. However, I can't figure
out why this does not fail in CI since changes landed.
Please feel free to close out if this is not expected changes. It is
entirely possible my setup have some weird side effect to cause test
failures.

After speaking with @timneutkens, this PR provides a smoother experience to users trying to migrate over to app without affecting users in pages.
This PR adds a new export available from `next/compat/router` that exposes a `useRouter()` hook that can be used in both `app/` and `pages/`. It differs from `next/router` in that it does not throw an error when the pages router is not mounted, and instead has a return type of `NextRouter | null`. This allows developers to convert components to support running in both `app/` and `pages/` as they are transitioning over to `app/`.
A component that before looked like this:
```tsx
import { useRouter } from 'next/router';
const MyComponent = () => {
const { isReady, query } = useRouter();
// ...
};
```
Will error when converted over to `next/compat/router`, as `null` cannot be destructured. Instead, developers will be able to take advantage of new hooks:
```tsx
import { useEffect } from 'react';
import { useRouter } from 'next/compat/router';
import { useSearchParams } from 'next/navigation';
const MyComponent = () => {
const router = useRouter() // may be null or a NextRouter instance
const searchParams = useSearchParams()
useEffect(() => {
if (router && !router.isReady) {
return
}
// In `app/`, searchParams will be ready immediately with the values, in
// `pages/` it will be available after the router is ready.
const search = searchParams.get('search')
// ...
}, [router, searchParams])
// ...
}
```
This component will now work in both `pages/` and `app/`. When the component is no longer used in `pages/`, you can remove the references to the compat router:
```tsx
import { useSearchParams } from 'next/navigation';
const MyComponent = () => {
const searchParams = useSearchParams()
// As this component is only used in `app/`, the compat router can be removed.
const search = searchParams.get('search')
// ...
}
```
Note that as of Next.js 13, calling `useRouter` from `next/router` will throw an error when not mounted. This now includes an error page that can be used to assist developers.
We hope to introduce a codemod that can convert instances of your `useRouter` from `next/router` to `next/compat/router` in the future.

Improvement to how the `app` and `pages` files conflict is shown.
Especially the last log line `"pages/" - "app/"` made it seem like you
should remove the `pages` folder altogether. This was a bug in how the
`''` case was displayed. After having a look at this I went further and
added exactly which file caused the conflict given that `app` allows you
to create `app/(home)/page.js` and such it saves some digging for what
the actual conflicting file is. Similarly in `pages` both
`pages/dashboard/index.js` and `pages/dashboard.js` are possible.
Before:
```
error - Conflicting app and page files were found, please remove the conflicting files to continue:
error - "pages/another" - "app/another"
error - "pages/hello" - "app/hello"
error - "pages/" - "app/"
```
After:
```
error - Conflicting app and page files were found, please remove the conflicting files to continue:
error - "pages/another.js" - "app/another/page.js"
error - "pages/index.js" - "app/page.js"
error - "pages/hello.js" - "app/hello/page.js"
```

This PR implements a configuration option in `next.config.js` to support
for rust-based MDX compiler (https://github.com/wooorm/mdxjs-rs).
Currently it is marked as experimental, as mdx-rs and loader both may
need some iteration to fix regressions.
When a new experimental flag is set (`mdxRs: true`), instead of using
`@mdx/js` loader `next/mdx` loads a new webpack loader instead.
Internally, it mostly mimics mdx/js's loader behavior, however actual
compilation will be delegated into next/swc's binding to call mdx-rs's
compiler instead.
I choose to use next-swc to expose its binding function, as mdx-rs
internally uses swc already and creating new binary can double up
bytesize (with all the complex processes of publishing new package).

This adapts the new client hooks of `usePathname`, `useSearchParams`,
and `useRouter` to work within the `pages/` directory to aid users
attempting to migrate shared components over to the `app/` directory.
> **Exception:**
> When the pages router is not ready, `useSearchParams` will return an
empty `URLSearchParams`. This mirrors the behavior seen in the `pages/`
directory today in that `router.query` is not available until the client
hydrates.
This also adds a new option for `useRouter` to bring it line with the
correct typings with the app directory. By default, calling
`useRouter()` will return the type `NextRouter | null` to represent what
you get when you call it from a component originating from the app
directory. If you want to instead force it to return `NextRouter` as it
does today, you can pass a boolean into the `useRouter` call as such:
```ts
const router = useRouter() // typeof router === NextRouter | null
const router = useRouter(true) // typeof router === NextRouter
```
This change is designed to ease the incremental adoption of app.

Following up https://github.com/vercel/next.js/pull/42012 this adds an
additional prompt for include ESLint config/dependencies or not. As
discussed, this also removes the slow down from doing separate
`dependencies` and `devDependencies` installs since this separation is
no longer required now that we have `output: 'standalone'` which ensures
only actual necessary dependency files are used for production builds.

Fixes#41856. There is no way to apply those loader rules to specific
directories, especially when `transpileModules` is used. This PR changes
that to be based on the issuer layer.

Resubmitting this PR following this comment from Tim. This work has been done already and we can build off of it to get this in faster.
> Just to be clear we're planning to rework create-next-app to give you the option to choose between JavaScript or TypeScript so it'll solve this request. For `app` right now it'll stay TypeScript till that is implemented.

I added the `--ts, --typescript` flag to `create-next-app` in https://github.com/vercel/next.js/pull/24655, and since then I have seen it used very frequently, including in recent issues (such as https://github.com/vercel/next.js/issues/33314) and most Next.js tutorials on YouTube. I noticed the template logic added in this PR was also used to add the `appDir` configuration as well.
We discussed a while ago adding the following user flow:
- `create-next-app --js, --javascript` creates a JS project
- `create-next-app --ts, --typescript` creates a TS project
- `create-next-app [name]` (no `--js, --ts`) prompts the user to choose either JS or TS, with TS selected by default.
### Review
Adding support for appDir and refactoring the templates brought the pain-of-review up a bit, but it's not so bad when broken into increments.
The original 8-file diff is here:
1f47d9b0bf
And the PR that brought the diff up to 59 files (mostly owed to `app` template dirs and file structure refactors):

fixes https://github.com/vercel/next.js/issues/42006
this issue occurred because images with `data url` src start with `blob`
and `data` will be mark as `unoptimized`, then its `sizes` will be
assigned with `undefined`.
I just skip the check for `data url` images, if there is any better
solution, we can have a discuss here.

This PR updates test fixture setup to pass `--turbo` when devserver is
initiated. Due to lot of existing tests are not working with turbopack
yet, changes are focused to setup necessary logics for the fixtures
only. With this change we can create some sort of burndown list to fix
forward.

Previously, creating the `app` dir without enabling the config would
print an error about `pages` missing:
> Couldn't find a `pages` directory. Please create one under the project
root
This PR prints a better error message:
> The `app` dir is experimental. Please add `{experimental:{appDir:
true}}` to your `next.config.js` to enable it

For `next/legacy/image`, the `data-nimg` has the `layout` prop value.
Since `next/image` doesn't have a `layout` prop, we can use `fill` when
the fill prop is used or fallback to `1`.
Next.js 13 will require React 18.
In this PR I've only updated the peerDependency and removed the test runs in GH actions. Further cleanup will follow later, this allows us to remove the code supporting it later.

This PR adds a new configure property, `images.loaderFile` that allow
you to define a path to a file with an exported image loader function.
This is useful when migrating from `next/legacy/image` to `next/image`
because it lets you configure the loader for every instance of
`next/image` once, similar to the legacy "built-in loaders".

Updating size-adjust calc to use azAvgWidth instead of xAvgCharWidth
Co-authored-by: Hannes Bornö <hannes.borno@vercel.com>

This PR fixes two bugs:
- Fixes#40419
- Fixes#41393
The first is when the aspect ratio of the `width` and `height` does not
match the aspect ratio of the `blurDataURL` provided. This can result in
artifacts around the edges. The solution is to add
`preserveAspectRatio="none"`.
The second is when there is no `width` or `height` provided (which is
normal when using `fill`) so the viewBox was undefined. This can also
cause artifacts around the edges. The solution is to change the blur
technique from gaussian to css filter, similar to `next/legacy/image`.
Note: css blur might be [slower in
firefox](https://bugzilla.mozilla.org/show_bug.cgi?id=925025) which is
why we'll only use it for this corner case.
Remove `browsersListForSwc` since it is enabled by default now, and disable `legacyBrowsers` by default.
This PR also bumps the default browserslist to the following:
- Chrome 64+
- Edge 79+
- Firefox 67+
- Opera 51+
- Safari 12+
See related RFC:
- Closes#33227

The `target: serverless` config was deprecated a year ago starting in
[Next.js 12](https://nextjs.org/blog/next-12).
Tests were disabled in #41252 so we can now remove `target: serverless`
and all usage of `target` in `next.config.js`.

- Enable newNextLinkBehavior. See #36436
- Run next/link codemod on test suite
Note that from when this lands on apps trying canary will need to run
the new-link codemod in order to upgrade.
Ideally we have to detect `<a>` while rendering the new link and warn
for it.

This PR introduces breaking changes by renaming components.
- Rename `next/image` to `next/legacy/image`
- Rename `next/future/image` to `next/image`
The diff is very confusing because both components are very similar so git got confused.
Gracefully parse the environment package manager when calling
`create-next-app` instead of passing extra arguments.
