# 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

When there's an error in the one of the root level pages, there's no way to handle it. The team discussed this and decided there should be a global error boundary to pick up anything not handled further down in the tree. It can be called `global-error.js`.

The json schema was incorrectly warning because `port: ''` is valid and we document and use it in examples. The empty string is different than undefined
- empty string: match only URLs without a port
- undefined: match URLs with any port
I noticed this when running one of our examples:
```
pnpm next dev examples/image-component
ready - started server on 0.0.0.0:3000, url: http://localhost:3000
warn - Invalid next.config.js options detected:
- The value at .images.remotePatterns[0].port must be 1 character or more but it was 0 characters.
See more info here: https://nextjs.org/docs/messages/invalid-next-config
```
## Bug
The `findDOMNode` will be exported from ReactDOM in esm mode, but it's
not defined for SSR since SSR is using react-dom server stub bundle
which doesn't contain any thing. So `import { findDOMNode } from
'react-dom'` will error in that case with bundling.
Since it's only being used on client, we import ReactDOM and call
`ReactDOM.findDOMNode` to avoid bundling error and adding a condition to
tree-shake it off on client

This PR fixes#41064.
In some particular cases, while using a middleware and shallow routing
the navigation get stucks and stop refreshing the page. After futher
investigation it seems that a line of code was added that causes the
router pathname to be incorrect and then making Next believe it's the
same page that is loading.

Add default head to app dir, when there's no`head.js`, use the default
head with the following meta tags
```html
<meta charSet="utf-8" />
<meta name="viewport" content="width=device-width, initial-scale=1" />
```
It will be replaced if there's custom head.js in child layout.

Fixes [#43367
(comment)](https://github.com/vercel/next.js/issues/43367#issuecomment-1338617317)
This fixes the issue in which pages that are in Route Groups return
status code 500 when built with `output: "standalone"` because of the
lack of required chunks in `.next/standalone/.next/server/chunks` by
handling their `.nft.json` files properly through using their
denormalized page paths, rather than their normalized ones to resolve
those files in `copyTracedFiles`.

Previously, query parameters were not available on 404 pages because
calling the router methods would change the pathname in the browser.
This change adds support for the query to update for those pages without
updating the path to include the basePath.
This additionally narrows some Typescript types that were previous set
to `any` which highlighted some type errors that were corrected.

arrow function was trying to use arguments binding but wanted arguments
of the lambda not the nearest normal function. The narrowest change is
to convert to function expression. We could also use varargs rest syntax
since this runs in runtimes that should all support that I think. I
don't think it really matters though.

## Context
There has been [some reports ](https://github.com/vercel/next.js/issues/42514)of OOMs-related crashes with Next 13. Whilst we're fixing the memory leaks that are causing this, some of which are caused by upstream issues, this PR makes Next.js' dev server restarts if it detects that it is gonna crash soon.
You can disable this behaviour by passing `__NEXT_DISABLE_MEMORY_WATCHER=1` to the env process.
## Details
Under the hood, we're using Node's cluster API to create a child worker that will basically watch the memory usage after every request and then kill itself if it goes over 90% of the maximum heap allowance.
## Test plan
I added manually a leaking function that I called before handling a request. I then manually tested that the server re-started when we were near the limit.
```
function createMemoryLeak() {
console.log('createMemoryLeak', process.memoryUsage().heapUsed / 1024 / 1024)
for (let i = 0; i < 10; i++) {
buffer.push(new Array(1000000).fill('a'))
}
}
```

Currently `useSearchParams` bails out of static generation altogether, forcing the page to be dynamic. This behaviour is wrong. Instead it should still be statically generated, but `useSearchParams` should only run on the client.
This is achieved by throwing a "bailout to client rendering" error. If there's no suspense boundary the whole page will bailout to be rendered on the client. If there is a suspense boundary it will only bailout from that point.
~This PR also adds handling for `export const dynamic = 'force-static'` combined with `useSearchParams`. If it is enabled it will return an empty `ReadonlyURLSearchParams` and skip the bailout to client rendering. Since the `staticGenerationAsyncStorage` only is available on the server - `forceStatic` is sent to the `app-router` to enable sending an empty `URLSearchParams` to match the server response.~
https://github.com/vercel/next.js/pull/43603#discussion_r1042071542 the implementation was wrong, added skipped tests and todo comment for now.

This PR doesn't change any behavior, its just refactoring.
- renamed `webpack/loaders/next-image-loader.js` to `.ts`
- moved duplicate code into shared function `optimizeImage()`
- support `height` as optional param
- convert `extension` to `contentType`
This will reduce the bundle size and also give user proper hint to upgrade to `head.js`
* Mark `next/head` as noop in app dir
* Add warning for users to check the upgration guide to migrate it to head.js
This PR fixes two memory leaks I found debugging with @sokra.
## 1) Leak in `next-server.ts`
The first leak was caused by the fact that the `require.cache` associated to the `next-server` module was not being cleared up properly, so we leaked context from modules required in that page, like API routes.
## 2) Leak with React Fetch
When evaluating a route, we also evaluated the `react.shared-subset.development.js` module where React patches the `fetch` function. The problem is that when re-evaluating a route as part of hot reloading, we were patching over the previously patched `fetch` function.
The result of this operation meant that we were keeping a reference to the context of the previous `fetch` and thus to the previous route context, thus creating a memory leak, since we only needed the new context.
## Test plan
Checked manually the heap snapshots of a test app.

As @timneutkens pointed out [here](https://github.com/vercel/next.js/pull/43819#discussion_r1042408158), changing the key will make Flight's module cache grow indefinitely. While I've thought about updating Flight's logic to clean the cache at some point, but that's tricky to do correctly as everything is asynchronous and we have to trigger clean up from outside (Webpack).
So currently, a better way I can think of is to just give Flight a proxied object as `moduleExports`. Even if Flight is getting the same object from cache, it will always require the latest module from Webpack.

Updated version of the reverted https://github.com/vercel/next.js/pull/43511
Unhandled errors that did not occur during React rendering (those errors are caught in `getDerivedStateFromError` in the Error Overlay) should be opened in the minimized toast state instead of fullscreen. For example if they occur in event handlers or setTimeout. Errors that breaks the app, such as uncaught render errors or build errors, still opens up in fullscreen mode.
The added test make sure the errors opens up as minimized, but if there's a breaking error it should "win" and open up in fullscreen. The updated tests either throw errors inside an event handler or a setTimeout, or the error is handled in a custom error boundary - which means the app don't break.
Closes NEXT-128
