## 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.
The PR follows #56536 and #56491, replacing `fs-extra` usages inside the `scripts/` folder.
Note that the `copy` and `move` haven't been replaced yet. Currently, there is no better recursive copy (lightweight, promise-based, Node.js built-in `copyFile` API-based, support the `filter` option) library alternative available on npm, and Node.js built-in `fs.rename` doesn't support `overwrite`.
The PR also replaces many async fs API usage with their sync versions.

In an attempt to avoid introducing experimental features into the Next.js userland space, we're reverting the `Promise.withResolvers` polyfill and preferring an internal `DetachedPromise` interface.
This PR introduces a new API, `unstable_noStore`, which will allow users to declaratively opt out of caching anywhere during static generation in the same way that you can specify `cache: 'no-store'` on a fetch call in Next.js.
An important caveat and difference from just calling `cookies()` to opt-out of static generation is that this won't opt you out when called from within `unstable_cache` and instead defers to the cache configuration to it.
```
import {unstable_noStore as noStore} from 'next/cache';
export default async function Component() {
noStore();
const result = await db.query(...);
}
```

This PR therefore introduces to always set response status code to 500
unless it is a `NotFoundError` or `RedirectError`. This PR would fix
issue #56235. See also:
https://codesandbox.io/p/sandbox/nice-panini-2z3mcp .
**Current Behavior**
At the moment, when an unexpected error occurs during app server
rendering, a 200 ok is returned as status code. This seems to be
undesirable because of the success status CDNs will cache the error
pages and crawlers will index the page considering the error content as
the actual content.
**Desired Behavior**
This issue is related to discussion
https://github.com/vercel/next.js/discussions/53225. Even though I
understand that the response status code cannot be set if streaming has
started, in my view it would be best to set the response status to 500
whenever it can (so before the streaming has started) for SEO and (CDN)
http caching. This would also be consistent with how 404s currently
work; that is, response status code is set to 404 if `NotFoundError`
occurred before streaming (related
[issue](https://github.com/vercel/next.js/issues/43831) &
[PR](https://github.com/vercel/next.js/pull/55542)).
Ideally, when a runtime error happens after streaming, a `<meta
name="robots" content="noindex" />` would also be added. But I didn't
want to make the PR too complex before receiving feedback.

follow up to #56898 where I noticed that we don't apply any filtering to the trace files for the user routes, resulting in files that would need to be filtered like `caniuse` not being filtered out correctly. This fixes that.
A lambda in my test project goes from `2.7MB` to `1.4MB`
followup: add some snapshot tests

### What?
Update Babel packages across the board
### Why?
Since you ship vendored presets and plugins it's impossible for people to update this stuff at their own pace - independently from Next. So users of `next/babel` are currently stuck with old versions and, for example, they might not be able to use the TS `satisfies` operator.
### How?
I just updated ranges (to pinned ones) where I could find them, run `corepack pnpm i` and re-run build scripts in the `packages/next`.

### What?
BREAKING CHANGE: Bump the minimum required Node.js version.
### Why?
Node.js 16 has reached end-of-life in September.
Bumped to `18.18.2` since it contained some security-related patches: https://nodejs.org/en/blog/vulnerability/october-2023-security-releases
### How?
Bumped `engines` where needed, upgraded the workflows.
This will allow us to remove quite a few polyfills, I'll open separate PRs for those.
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).

Since Turbopack doesn't use eval-source-map the CSP nonce will pass correctly, nice improvement over the current state where you can't check CSP in dev.
This ensures `import url from 'url'` works in the edge runtime when using Turbopack. It also ensures the stubs for fetch / object.assignare applied to the client and edge compilation.
Fixes a bunch of the Turbopack test failures for `test/e2e/app-dir/app/index.test.ts`. Not sure how this passed with webpack before as the dep was indeed missing.

### What?
Adding back `x-forwarded-*` headers.
### Why?
Starting with #52492, these headers were lost.
