Prebundle react for appDir (#41337)
Inline a react and react-dom for app dir, when `appDir` flag is enabled
opt into the built-in version for all.

For server layer react, use the react share subset for server
components.
For all server side of react-dom usage, use the server-rendering-stub.

BREAKING CHANGE: Remove target: serverless (#41495)
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`.

Include frameworks in main-app (#41465)
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.

Update flakey dev AMP tests (#41428)

Remove edge shared deps (#41413)
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.

BREAKING CHANGE: Rename next/image to next/legacy/image & rename next/future/image to next/image (#41399)
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.

Update middleware query hydration handling (#41243)
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.

Do not bundle react-dom in the SSR build (#41227)
Currently `react-dom` isn't handled as an external dependency in SSR,
unlike `react`. This means that the ReactDOM imported by client
components isn't the same instance as the ReactDOM that does SSR.

This PR also upgrades React experimental to the latest version.

Alias next/dynamic to lazy impl for appDir (#41216)
Since `next/dynamic` has client hooks that not compatible with server
components, and app renderer doesn't provide context (such as
`LoadableContext`) for it to use. Previously we provided a simple
replacement using `React.lazy` for `next/dynamic` if you want to use it
in appDir.

This PR always alias it to the `React.lazy ` implementation for appDir
so that user won't need to worry about the dynamic options. They can
only use `dynamic()` without 2nd options arg

```js
import dynamic from 'next/dynamic'

const Dynamic = dynamic(() => import('./dynamic-component'))
```

Disable built-in css-in-js transform on server layer (#41040)
We're supposed not to use css-in-js in server components since it will
increase the rsc response for navigation. Also adding `styledJsx` option
for next-swc for controlling styled-jsx transform.

Test case: using styled-jsx transform in server components will not be
transformed to `styled-jsx/style` imports.

add attribution to web vitals (#39368)
This commit implements the main proposal presented in
https://github.com/vercel/next.js/issues/39241
to add attribution to web vitals.

Attribution adds more specific debugging info to web vitals,
for example in the case of Cumulative Layout Shift (CLS),
we might want to know
> What's the first element that shifted when the single largest layout shift occurred?

on in the case of Largest Contentful Paint (LCP),
> What's the element corresponding to the LCP for the page?
> If it is an image, what's the URL of the image resource?

Attribution is *disabled* by default because it could potentially
generate a lot data and overwhelm the RUM backend.
It is enabled *per metric* (LCP, FCP, CLS, etc)

As part of this change, `web-vitals` has been upgraded to v3.0.0
This version contains minor bug fixes, please see changelog at
9fe3cc02c8

Fixes #39241

Use deterministic module IDs for server (#41066)
Currently, we use the `isClient ? 'deterministic' : 'named'` condition
for module IDs. We did that because in the context of server compiler,
the server graph (RSC) can directly know the module ID of the referenced
module in the client graph (SSR). The client module's ID _is_ the module
reference module's resource path. However, that makes the server bundle
and the manifest file larger because these module IDs cannot be
minified.

In this PR we are changing it to `deterministic`, with another mapping
for server SSR.

Alias all client, shared, pages dist assets for esm (#41034)
Alias all existing imports from `next/dist/..` to `next/dist/esm` for edge compiler. So that we don't need checking for `process.env.NEXT_RUNTIME === 'edge'` or passing down `nextRuntime` to decide wether the esm or cjs asset to require

This will also fix the issue that some layouts hook are been included twice into the bundle with cjs and esm bundle in edge runtime, now only esm chunk will be bundled in server.

Drop legacy React DOM Server in Edge runtime (#40018)
When possible (`ReactRoot` enabled), we always use
`renderToReadableStream` to render the element to string and drop all
`renderToString` and `renderToStaticMarkup` usages. Since this is always
true for the Edge Runtime (which requires React 18+), so we can safely
eliminate the `./cjs/react-dom-server-legacy.browser.production.min.js`
module there
([ref](https://unpkg.com/browse/react-dom@18.2.0/server.browser.js)).

This reduces the gzipped bundle by 11kb (~9%). Let me know if there's
any concern or it's too hacky.

I am doing some work re: bundle size so I'm spending a lot of time looking at the bundles we generate. This debug options basically deactives mangling and beautifies the output whilst keeping the dead code elimination from Terser which is helpful for me to check what I'm removing.

this is what the output is like with it.

edge-ssr: bundle next/dist as ESM for better tree-shaking (#40251) (#40980)
Re-do of https://github.com/vercel/next.js/pull/40251

Edge SSR'd routes cold boot performances are proportional to the
executed code size.

In order to improve it, we are trying to optimize for the bundle size of
a packed Edge SSR route.

This PR adds ESM compilation targets for all Next.js dist packages and
use them to bundle Edge SSR'd route.

This allows us to leverage the better tree shaking/DCE for ESM modules
in webpack in order to decrease the overall bundle size.

This PR also enables minifying Edge SSR routes. Since we don't control
which minifier might be used later (if any), it's best if we provide an
already optimised bundle.

This is a 10ms cold boot win per my benchmarking script, which I'll put
in a subsequent PR.

Not done yet:
- ~~swap exported requires in `next/link` (and others) etc to point them
to the esm modules version~~

Fix SWC loader ignore for the server layer when Babel is used (#40939)
Specific logic to handle the file transpilation on the server layer is
implemented in SWC (#40603). When Babel is enabled, that SWC transform
is ignored at the moment. In this PR we add an additional SWC pass after
Babel to handle that.

Fix bundling and module resolution in the server layer (#40818)
We currently resolve the `react-server` condition correctly inside
`externals` for the server layer, however that will cause the resolved
path to be external (as it is called "externals").

So we need a way to hook into the module resolution process to force it
to use the `react-server` condition **when it's on the server layer**.
The `resolve` option doesn't give us that ability, and the solution in
this PR is to leverage `normalModuleFactory`'s resolve hook to override
the resolve options before actually resolving it. And there we can have
the `contextInfo`.

One thing left out is bundling for the edge server, we need to add tests
and sort that out carefully.

edge-ssr: bundle next/dist as ESM for better tree-shaking (#40251)
# Context

Edge SSR'd routes cold boot performances are proportional to the
executed code size.

In order to improve it, we are trying to optimize for the bundle size of
a packed Edge SSR route.

This PR adds ESM compilation targets for all Next.js dist packages and
use them to bundle Edge SSR'd route.

This allows us to leverage the better tree shaking/DCE for ESM modules
in webpack in order to decrease the overall bundle size.

This PR also enables minifying Edge SSR routes. Since we don't control
which minifier might be used later (if any), it's best if we provide an
already optimised bundle.

This is a 10ms cold boot win per my benchmarking script, which I'll put
in a subsequent PR.

Not done yet:
- ~~swap exported requires in `next/link` (and others) etc to point them
to the esm modules version~~

Should resolve esm external module imports on server (#40865)
### Issue

When import an esm package in client component, and use it in server
component page, it will fail to SSR but render successfully on client.
It's because the import to esm package will make the client chunk become
an **async module** since esm module will be treated as **async**.

```
page (serve component) -> local module (client) -> external dependency (esm)
```

Then in react SSR layer, it need the module type information of that
chunk, async or not for react so that react could unwrap the async
module from `Promise` properly when SSR.

### Solution

We need to mark the client entries which are effected by async/esm
modules that becoming **async** as `async: true` in SSR manifest.

Since flight manifest plugin is only running against client compiler,
which doesn't have those module information from server compiler. So we
collect the async modules from the **server** compiler **client** layer
from flight entry client plugin, then leverage the collection to detect
if a module is async in flight manifest plugin for react.

Add local font loader (#40801)
Moves font related types to `next/font` so they can be reused in font
loaders.

Adds an argument to font loaders, the relative path from the app root to
the module consuming the loader. Needed for resolving local files
relative to the module calling it. Also used to improve error message.

Adds `@next/font/local` font loader. Similar to `@next/font/google` but
used to host locally downloaded font files.

Fix alias paths for bundling (#40800)
In the server layer, we used to alias `react` to the resolved path e.g. `/next.js/node_modules/.pnpm/react@0.0.0-experimental-e6a062bd2-20220913/node_modules/react`, but it turns out that webpack's enhanced resolver can't handle it correctly together with conditions, and the final resolved path is `/next.js/node_modules/.pnpm/react@0.0.0-experimental-e6a062bd2-20220913/node_modules/react/index.js`. If we change the alias to `react: 'react-exp'` then it correctly resolves to `/next.js/node_modules/.pnpm/react@0.0.0-experimental-e6a062bd2-20220913/node_modules/react/react.shared-subset.js`.

Add support for font loaders (#40746)
For some context:
[https://vercel.slack.com/archives/CGU8HUTUH/p1662124179102509](https://vercel.slack.com/archives/CGU8HUTUH/p1662124179102509)

Continuation of #40221 and #40227

Adds `experimental.fontLoaders`.

SWC next-font-loaders (#40221) transforms font loader (e.g. #40227) call
expressions into an import with the function call arguments as a query.

The imports will be matched by `next-font-loader`. It runs the
configured font loaders - emits font files and returns CSS. Exports are
added, and the font-family is made locally scoped. The returned CSS is
turned into a CSS module with `css-loader` which lets you consume the
font-family.

`FontLoaderManifestPlugin` creates a manifest of the preloaded font
files for each entrypoint. Preload/preconnect are then added in
`_document.tsx` if any font files were found for that path.

Strip internal pages for pagesDir in app edge ssr (#40776)
For app edge SSR, we don't need any internal pages for it since it's
handled by app-renderer. This results around reducing 20KB from app edge
SSR

# Changes
* Strip those internal pages modules when it's in app edge SSR
* Minimize edge SSR chunk to see the tree-shake result
* Add bundle analyzer with switcher in stats-app for testing. Using
`TEST_ANAYLYSE=1` to build stats-app for testing

Remove unnecessary experimental flag (#40766)
`config.experimental.serverComponents` is currently required to be
enabled or disabled together with `config.experimental.appDir` (which
means `serverComponents === appDir` otherwise it will throw) so there is
no reason to keep both of them. This PR removes `serverComponents` from
Next.js and only rely on `appDir` instead.

Improved bundling strategy for the server graph (#40739)
This PR changes the external module resolution to eagerly bundle
node_modules, and some specific Next.js internal modules, if on the
`WEBPACK_LAYERS.server` layer. While resolving corresponding packages,
we use the `react-server` export condition (fallbacks to default).

A follow-up PR will be adding a Next.js option to opt-out specific
packages from being bundled on the server layer.

Refine error messages (#40661)
As per @sebmarkbage's suggestion, this PR refines the error message to
be more readable and friendly:

```
error - ./components/qux.js

You're importing a component that needs useEffect. It only works in a Client Component but none of its parents are marked with "client", so they're Server Components by default.

   ,----
 5 | import { useEffect } from 'react'
   :          ^^^^^^^^^
   `----

Maybe one of these should be marked as a "client" entry:

./components/qux.js
./components/baz.js
./components/bar.js
./app/dashboard/index/page.js
```

It's more ideal to put error codes inside the SWC transform and format
it in the Next.js logging layer. A future improvement is to tweak the
message a bit more for these specific cases:

- [ ] The error already happens inside an entry point (page or layout),
so itself should have "client" added (or removed), not it parents.
- [ ] When importing `"server-only"` inside a client component, we can
directly hint to the user which module in the import chain is marked
with `"client"`.

Client directive (#40415)
## Feature
Change server components convention from using `.server.js` / `.client.js` file extension to determine it's a server or client component to using `'client'` js literal as a directive for determine client components boundary.
React RFC: https://github.com/reactjs/rfcs/pull/189
New behavior doesn't consume `.server.js` as server components any more, if you're enabling `serverComponents` flag, every `page.js` in app dir will become server components by default. If you adding a `'client'` directive to the page, then that page will become a client component. This rule also applies to the normal js components, client components will require a `'client'` directive to indicate its identity, instead of having a `.client.js` extension.
