This PR implements next.config.js's `modularizeImports` option to
turbopack. It tries to read next.config.js, and then apply transforms as
same as `next-swc` does. Internally it interops betwen next.config.js's
PackageConfig to swc's PackageConfigs, as it doesn't have necessary
attributes for the Vcs / deserialization.
We decided in https://github.com/vercel/next.js/pull/48308 that we won't
use `turbo` when packing packages for tests.
This PR removes all code associated with that effort. The whole thing
fas behind a flag, so it shouldn't affect anything.

### How?
Closes NEXT-

### What?
This PR enforces turbopack uses `automatic` jsx runtime.
- closes WEB-901.
### Why?
If you set `ts|jsconfig`'s `jsx` to any custom value, you'll encounter
next.js message
```
The following mandatory changes were made to your tsconfig.json:
- jsx was set to preserve (next.js implements its own optimized jsx transform)
```
Then internally transform sets jsx to use automatic runtime instead. In
case of turbopack, its transform pass is embedded so instead of setting
it to preserve falls back to automatic by default. PR doesn't handle
validations / or emitting user friendly messages yet, just enforce
runtime config regardless of how user sets it.
There maybe some additional followups to mimic exact transform existing
next.js does.

### What?
* fix app dir chunking
* fix app dir 404s
* improve app dir performance
* rerender shadowportal on errors to re-add nextjs-portal to avoid empty
page
* inject polyfills before user code
* fix manifest generation
see also https://github.com/vercel/turbo/pull/4488
### Why?
App dir was very slow and lead to 404 errors
### How?
add included metadata to chunks to allow deduplicate chunk loads at
runtime
### Description
The next.js router will proxy requests if there's a rewrite with an
external URL, for POST requests this currently leads to an `ECONNRESET`,
because the client request has no body.

### What?
* move some shared runtime logic to turbopack
* use relative imports from internal code when possible
* move react-refresh logic to turbopack
* move benchmark code logic to turobpack
see https://github.com/vercel/turbo/pull/4553
### Why?
We want to have benchmarking again for turbopack PRs
We want to have a standalone turbopack cli (eventually)
We want to avoid duplicating the runtime code
### How?
refactoring, moving code
This accomplishes 2 things:
1. binds the turbopack dev server to the IPv6 unspecified address
2. initializes our router with the same hostname/port of the turobpack
server
The first matches the behavior of the Node.js dev server. The IPv6
unspecified address is similar to IPv4's `0.0.0.0` address, allowing us
to accept connection from anywhere. Importantly, it _also_ allows
accepting IPv4 connections, making this address truly universal.
The second means the `request` parameter to any middleware will have the
correct origin, and the request's URL can be used to craft fetch
requests to API endpoints. `new URL(req.url).origin` will be the origin
of the turbopack dev server.
Fixes https://github.com/vercel/turbo/issues/4456
Fixes WEB-855
### What?
Fix missing `,` in loader tree code.
also adds `unsupported` as category of implicit metadata issue
### Why?
The loader tree to JS generated invalid code when there there where two
non-page files in a directory.
fixes WEB-861
Next.js adds a `Vary: RSC, Next-Router-State-Tree, Next-Router-Prefetch`
to app routes for both rendering and flight requests. Without this, the
browser can mistakenly serve the flight request to the app render, and
vice versa.
This only adds `Vary: RSC` for the moment, I'm not sure what the others
are used for. We also don't add a `Cache-Control: max-age=0` header, but
I'm not sure if that's necessary either.
Fixes NEXT-657
fix#45595
### What?
avoid including the error twice in the output
### Why?
`.context()` already keeps the previous error, no need to include in the
error message again
### What?
enables the benchmark tests from turbopack again
### Why?
It tests common scenarios like HMR

When the devs have a parse/module-eval error in their Page/App module, Turbopack's rendering process will fail to connect the IPC. This is because the entrypoint statically imports the dev module. If either fails, then we'll never reach the code to set up the IPC. This leads to a "timeout while receiving message from process" timeout error after 30s, instead of receiving an exact message/stack detailing the dev's error.
By wrapping the import code in a deferred dynamic-import closure, we're able to connect the IPC first, then evaluate the dev code. This wrapping style is a little awkward, but it's necessary with the way to inject virtual modules into our graph.

### What?
This PR implements a feature for the turbpack to support (partial)
transform configuration inherited from ts/jsconfigs, notably for the
legacy decorators and jsx runtimes.
### Why?
### How?
- Closes WEB-667
### What?
Refactors the resolving logic for the `app` loader tree. This PR ensures
it's used to create entrypoints in turbopack. Next up is integrating it
into the webpack build too.
These changes also ensure that parallel routes resolving is applied,
which previously wasn't supported in turbopack.
### Why?
Part of the effort to deduplicate critical logic between
turbopack/webpack in Next.js, this will help land features in
turbopack/webpack at the same time.
### How?
Quite a few changes. @sokra helped a ton on this PR. `app_structure.rs`
was changed to the new resolving logic so most of the logic is there.
Additionally we added support for calling the same function in two ways
from Node.js: `turbo.entrypoints.get` and `turbo.entrypoints.getStream`.
`get` can be used by `next build` to get the full list of
entrypoints/loadertrees once. `getStream` has watching built-in and
calls a callback function with the new list anytime a file is added that
would change the loadertree.

We need a full process polyfill to fix some edge cases
Also disables SourceMap for edge chunks, since they are not used
### Why?
Some packages do weird things, e. g.
```
var isBrowser = process.title === 'browser'
```
Turbopack starts up the router process with all ENV values, but the edge
function definition didn't list any `env` keys for the function
invocation. So, middleware couldn't access any ENV values.
Turbopack doesn't currently have a way to determine what ENV keys are
actually used by the source program, so I'm just passing everything
defined. I'm not sure if that's an issue during dev (I could see it
being one for the build process, but that doesn't matter for this case).
Fixes#47766
Fixes WEB-831
Fixes WEB-834
Paired with https://github.com/vercel/turbo/pull/4329, this implements
streaming responses for App and API renders. This is accomplished by
sending an initial `headers` message (carrying the status code and
headers list), N `body-chunk` messages of bytes, and a final `body-end`
message to signal completion.
Once sent to Turbopack, these chunk messages will be streamed out of the
node rendering process directly into the HTTP server's response.
Closes WEB-27

### What?
This PR adds an internal compile time flags for the `next-swc`, which exposes two runtime apis into next.js to initialize heap-profiling enabled memory allocator and teardown those once next.js exits. While there are newly added 2 js interfaces (`initHeapProfiler`, `teardownHeapProfiler`) underlying napi binary itself have compile time flags to actually enable those feature: any user who runs npm-published next.js cannot enable this features with any kind of runtime configuration. Only manually built next-swc binary with specific flag can enable this. Since this is primarily for the CI testing workflow only, those flag / configs are not visibily exposed as well.
### Why?
It is for some experiments on the CI to see if it can observe some of memory pressure issues (WEB-593, WEB-804) while it is not easily reproducible on the local machines.
Based on some suggestions from @sokra, this serves to unify the Route Handlers and Route Modules to provide a unified interface for defining route modules and handlers and defining their dependancies.
just took a bit of banging my head against the wall 👀
the `'dynamic route/page check'` route resolves `fsRoutes` (which leads to an object with `{pages: undefined}` because the route doesn't have the list of pages(?))
that route only gets enabled if you have fallback rewrites though

Part of WEB-736.
This PR refactors imports to turbopack to turbo-binding, as same as we
used to do with next-binding. Current next-binding in this repo doesn't
make sense anymore and removed. There are no functional changes. This'll
reducwe surface for the imports and also will make easier to run
integration test over latest turbopack.
Note swc dependency is not reflected in this PR yet - following PR will
update those imports.
Previously the app route handler was included in the server bundle, and called into user code to execute the underlying handler logic. This PR serves to move the handler code into the bundle so that the Node.js environment more closely matches the Edge environment.
This also updates the Rust code for the new loader.
fix NEXT-712 ([link](https://linear.app/vercel/issue/NEXT-712))
Also refactors the `Errors` state into a reducer, which makes things a bit easier to reason about (in my opinion)
I tried adding an ID to the issue, so we don't have to stringify the whole issue, but unfortunately that duplicates (parsing issues)
the reason is probably that files get parsed twice, once for the client and once for the server side
Fixes WEB-787.
This implements automatic font fallbacks for `next/font/local`. It uses the `allsorts` library to query font metrics across woff and ttf fonts.
Test Plan: Now passes 24 Next.js integration tests, up from 14.
Currently in a client boundary file, we only explicitly export
individual fields in ESM (`export foo`) when the source type is
`module`. However in most of the time SWC gives the `auto` source type.
This PR improves the type detection a bit so if it's `auto` and we do
see ESM exports collected, we assume it's ESM and re-export these
fields.

Fixes WEB-249
Depends on vercel/turbo#4288
This implements support for `next/font/local` for Turbopack. It:
* Removes the compile-time feature restricting access to `next/font/local`
* Implements `NextFontLocalReplacerVc` and `NextFontLocalCssModuleReplacerVc`, similar to their `next/font/google` equivalents, and adds them as ImportMappings to handle requests for `next/font/local/target.css` and `@vercel/turbopack-next/internal/font/local/cssmodule.module.css` (these requests are created by the JavaScript returned by the requests for the `target.css` module)
* Implements fallback support for Times New Roman and Arial via `adjust_font_fallback` as the webpack implementation does. Font metric override adjustment will be added in a future PR.
Test Plan: New passes 14 next-font integration tests in the Next.js integration test suite, up from 8.
Previously `next-swc` had relay transform inline, but it makes
maintenance harder. So this PR patches next-swc to use relay plugin from
`swc-project/plugins` repository.
