Check whether SWC is used or not by checking "useSWCLoader" variable, not by checking "babelConfigFile".
Since we can bypass babel config file by turning on experimental.forceSwcTransforms, we should not check babel by its config file.

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 fixes the bug reported by @hanneslund (reproduction:
https://github.com/hanneslund/css-mod-import-test).
There can be multiple modules with the same resource, some of them can
be created via plugins (extracted by the mini-css plugin) and some can
be directly transformed via loaders (e.g. the CSS modules loader). In
these cases, we need to merge the resources generated by all of them.

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).

to get it from the font file. That way we know we won't get any invalid
characters in the font-family name.

When generating a fallback font family it will pick the font file with
the weight closest to normal, this will typically make up most of the

Removing the `hasReactRoot` condition and `__NEXT_REACT_ROOT` env var since next 13 requires latest react 18 to be installed, all the react 17 (non concurrent mode) compatible code can be dropped now.
Previously we use `path.join(compiler.context, chunk.name)` as the entry
name, which isn't always the case especially when there is the `src`
folder. This PR fixes that by using `appDir`.

When emitting the client components entry from server compiler, merging
app internal entry into main-app to avoid duplicated chunks like react
are generated in both sides
Related: https://github.com/vercel/next.js/issues/41870
We currently only fallback to the global `runtime` option if the page
actually **needs** a runtime (not statically optimizable). That happens
for SSG (ISR) and SSR for pages/. But for app/, we will always need a
`runtime` to render server components.
Also in this PR, I improved the tests to actually **test** the runtime
to ensure it has `globalThis.EdgeRuntime` so it's not running in the
Node.js runtime
([ref](https://edge-runtime.vercel.app/features/available-apis#addressing-the-runtime)).

We have existing rule for pages ssr that `next/dist/server` and
`next/dist/shared` will not be bundled, but we shouldn't apply it to rsc
layers since the they should bundle the dependencies in their own way.
Adding a test that using `next/head` in the page, since head is exported
from `next/dist/shared`, expect the page is not broken but we don't
expect it's working

By default the edge page entry is in the client layer because it bundles Next.js. It's a virtual loader (edge-ssr-loader) but that makes the SWC loader think the page's source is a client component.
We use the resource query `__edge_ssr_entry__` to convert it to the server layer but we need to add that condition to the SWC loader too.

When esm package that depending on react is used between `pages/` and
`app/`, it's loading the user installed react through esm loader which
doesn't go through require hook, so we cannot intercept it with
require-hook.
Disable esm resolving when `appDir` is enabled for now, prefering to
pick the cjs bundle so that react import is intercepted by require hook
and pointing to the built-in react

Bundle the ssr client layer for RSC, this solves the problem when
there's an esm package is using on client components, but esm imports
the installed react instead of the built-in react version since esm
imports is not intercepted by require hook.
After bundling the ssr client layer and treating react as externals, now
react compiles as cjs externals and could be intercepted by require
hook, other code are bundled together which can also get optimized.

This PR updates `@types/node` to `14.14.31`. The most important type is
that `ParsedUrlQuery` can hold `undefined` so we are updating the code
here to explicitly handle those cases. Aside from it we are adding a
global definition taken from NodeJS for `AsyncLocalStorage` that we
export in `server.d.ts`
Adds support for:
- outputting what kind of build we did for routes in the app folder:
SSR, SSG, static
- adds the list of SSG'd routes
- adds JS size for app routes

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".
We can't directly put `filePath` in the generated code as it can contain in valid JavaScript string such as `"\2"` in `"C:\Users\foo\2022\bar.js"`. Reference: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Errors/Deprecated_octal

It’s possible that global CSS imports, that come from node_modules, are
marked as side effect free because of possible `sideEffects: false` in
the external package's package.json. In that case, we still need to
handle global CSS imports as side effects on the server because we need
to collect them and avoid tree-shaking for these modules.
You can take a look at the test case to see what exactly happened.

- 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.

There is no need to have a separate `framework` chunk for React and React DOM, as they're already included in the `main-app` entry. With this PR, React and React DOM will be included in `main-app` directly and app is no longer depending on the `framework` chunk.

Since we have already bundled dependencies for server layer, so the
shared deps chunk group is not needed anymore.
Also changing to esm assets import with next internals for edge function
and middleware build.
The changes are originally from #41337, try to land them separately.
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.
Fixes tree shaking for font loaders in server components.

The way we currently track server CSS imports is to collect CSS files that each **module** depends on. This happens on the module graph level which is a global thing and cannot be tree-shaken properly (check the enabled test for more details).
In this PR we collect another information, of CSS files that each **entrypoint** depends on. This is the CSS list after tree-shaken on the entry level. By intersecting these CSS imports with the module-level CSS imports, we can get the final used CSS imports for each _layout_.

Fixes#41258
When we detect `type: "module"` in `package.json`:
~1. generate `server.mjs`~ Not necessary when `type: "module"` is set.
2. use `import` instead of `require`
3. replace `__dirname` with [ESM compatible
alternative](https://blog.logrocket.com/alternatives-dirname-node-js-es-modules/)
In this PR, I also moved some tests (those using `output: "standalone"`)
to a new `test/production/standalone-mode` directory for easier
discoverability in the future.
Run the related test with `pnpm test
test/production/standalone-mode/type-module/index.test.ts`

In Jest, we were mocking the `next/image` imports with a width and
height of `24`. If the developer set `placeholder="blur"` on their
images though, this triggered the warning:
> Image with src "/img.jpg" is smaller than 40x40. Consider removing the
"placeholder='blur'" property to improve performance.
Since we cannot reliably hide this warning without knowing the actual
image dimensions, and we also provide a `blurDataURL` by default, we
should increase the mock image size to suppress the warning.
Note that using `moduleNameMapper` in `jest.config.js`, the developer
can already tweak the mock behavior:

This updates to skip the data request done during query hydration when
middleware is present as it was mainly to gather query params from any
potential rewrites in middleware although this is usually not needed for
static pages and the context can be gathered in different ways on the
client.

Check that the module has assets. This might not always be the case in
app dev if there was an error. Test added to make sure it recovers
correctly.

## 🐛 What's in there?
`foo instanceof Function` is wrongly considered as Dynamic code evaluation by our static analyzer.
This PR fixes it.
- [ ] Related issues linked using `fixes #number`
- [x] Integration tests added
- [x] Errors have a helpful link attached, see `contributing.md`
## 🧪 How to reproduce?
1. Create a simple repro in `examples` folder:
```js
// examples/instance-of-function/pages/index.js
export default function Home() {
return <h1>home</h1>
}
// examples/instance-of-function/middleware.js
import { NextResponse } from 'next/server'
export default async function handler() {
console.log('is arrow a function?', (() => {}) instanceof Function)
return NextResponse.next()
}
```
1. build with next `pnpm next build examples/instance-of-function`
> the build fails
1. rebuild next to include PR's fix `pnpm build`
1. build with new next `pnpm next build examples/instance-of-function`
> the build works
## 📔 Notes to reviewers
`hooks.expression.for(`${prefix}Function`).tap(NAME, handleExpression)` is actually legacy code from the original implementation. It's used when finding `Function` regardless of how it is used. We only want to find `new Function()` or `Function()`, which `hooks.calls` and `hooks.new` are covering.
`eval instanceof Function` is perfectly legit code on the edge, despite its uselessness :lol-think:
Because we got multiple people asking "how do I relax this error when my code contains unreachable dynamic code evaluation", I've copy-pasted details about `config.unstable_allowDynamic` into the error page. Because users do not always click links :blob_shrug:
Move react-dev-overlay into hot reloader client components, and let it imported by app router. So then we don't need to have hot reloader and react tree as adjacent sibilings but the overlay with error boundary is wrapping the react tree

Changes how font loaders are configured in next config, makes more sense since options can be optional. Also adds error for when font loaders are used from within node_modules.
