x-ref: #31506
This PR migrates existing SSR on edge from middleware to edge functions implmentation. So that we can get rid of limitation of middleware and resolve the conflicts between middleware and edge SSR routes.
* Adding edge functions matching route in middleware catch all route,keep the order as `middleware catch all` -> redirects/rewrites -> `edge catch all` -> others
* Dropping middleware related code for edge SSR: removing client info and preflight request handling
In Middlewares, dynamic code execution is not allowed. Currently, we warn if eval / new Function are invoked in dev but don't warn another dynamic code execution in WebAssembly.
This PR adds warnings for `WebAssembly.compile` and `WebAssembly.instantiate` with a buffer parameter (note that `WebAssembly.instantiate` with a **module** parameter is legit) invocations. Note that other methods that compile WASM dynamically such as `WebAssembly.compileStreaming` are not exposed to users so we don't need to cover them.

* Ensure custom middleware matcher is used correctly in client manifest
* lint-fix
* patch e2e case
* fix rsc case
* update test
* add missing normalize
* Re-introduce Edge API Endpoints
This reverts commit 210fa39961, and
re-introduces Edge API endpoints as a possible runtime selection in API
endpoints.
This is done by exporting a `config` object:
```ts
export config = { runtime: 'edge' }
```
Note: `'edge'` will probably change into `'experimental-edge'` to show
that this is experimental and the API might change in the future.
* Support `experimental-edge`, but allow `edge` too

This commit enables the following patterns in Middleware:
```ts
// with a dot notation
const { ENV_VAR, "ENV-VAR": myEnvVar } = process.env;
// or with an object access
const { ENV_VAR2, "ENV-VAR2": myEnvVar2 } = process["env"];
```

## Bug
fixes#37106
Please note that, as for `pages/` the `src/middleware` file is ignored when `/middleware` is present.
## How to test
1. Rebuild next.js `pnpm build`
2. Run dedicated tests: `pnpm testheadless --testPathPattern middleware-src/`
It would be nice to have this attribute to compare runs with and without the `swcMinify` options.

Another strategy to do achieve the goal of #36995. With this PR the module IDs will be:
- (1) RSC: named (_this one doesn't matter_)
- (2) SSR: named
- (3) Client: deterministic
And we include the client module IDs in the flight manifest, as well as an extra mapping of 3) → 2) so during SSR it can require the correct module still.

Follow-up PR for #37134, this PR adds back the hash in each chunk's filename. This `chunks` in the flight manifest will now be `chunkId:chunkFilename` with this PR, and `globalThis.__next_chunk_load__` then handles the chunk registration (uses chunkId) and chunk loading (uses chunkFilename). (Q: how can we port this to React?)
We can't use `[contenthash]` but only `[chunkhash]` because at the stage of generating the flight manifest, the content isn't finalized and the hash changes after that.

We added custom _app as server component support in #33149, but we found it's pretty confusing on usage like support it both server component pages and regular pages at the same time for having similar layout purpose.
When using the _app.server and _app at the same time, applying them into proper places become more confusing.
In that case, we decide to make _app.js can't be a server component, and you can still keep all the existing thing there. And also you don't need to think of the corresponding APIs of custom _app in RSC

_Hello Next.js team! First PR here, I hope I've followed the right practices._
### What's in there?
It has been decided to only support the following uses cases in Next.js' middleware:
- rewrite the URL (`x-middleware-rewrite` response header)
- redirect to another URL (`Location` response header)
- pass on to the next piece in the request pipeline (`x-middleware-next` response header)
1. during development, a warning on console tells developers when they are returning a response (either with `Response` or `NextResponse`).
2. at build time, this warning becomes an error.
3. at run time, returning a response body will trigger a 500 HTTP error with a JSON payload containing the detailed error.
All returned/thrown errors contain a link to the documentation.
This is a breaking feature compared to the _beta_ middleware implementation, and also removes `NextResponse.json()` which makes no sense any more.
### How to try it?
- runtime behavior: `HEADLESS=true yarn jest test/integration/middleware/core`
- build behavior : `yarn jest test/integration/middleware/build-errors`
- development behavior: `HEADLESS=true yarn jest test/development/middleware-warnings`
### Notes to reviewers
The limitation happens in next's web adapter. ~The initial implementation was to check `response.body` existence, but it turns out [`Response.redirect()`](https://github.com/vercel/next.js/blob/canary/packages/next/server/web/spec-compliant/response.ts#L42-L53) may set the response body (https://github.com/vercel/next.js/pull/31886). Hence why the proposed implementation specifically looks at response headers.~
`Response.redirect()` and `NextResponse.redirect()` do not need to include the final location in their body: it is handled by next server https://github.com/vercel/next.js/blob/canary/packages/next/server/next-server.ts#L1142
Because this is a breaking change, I had to adjust several tests cases, previously returning JSON/stream/text bodies. When relevant, these middlewares are returning data using response headers.
About DevEx: relying on AST analysis to detect forbidden use cases is not as good as running the code.
Such cases are easy to detect:
```js
new Response('a text value')
new Response(JSON.stringify({ /* whatever */ })
```
But these are false-positive cases:
```js
function returnNull() { return null }
new Response(returnNull())
function doesNothing() {}
new Response(doesNothing())
```
However, I see no good reasons to let users ship middleware such as the one above, hence why the build will fail, even if _technically speaking_, they are not setting the response body.

This PR deprecates declaring a middleware under `pages` in favour of the project root naming it after `middleware` instead of `_middleware`. This is in the context of having a simpler execution model for middleware and also ships some refactor work. There is a ton of a code to be simplified after this deprecation but I think it is best to do it progressively.
With this PR, when in development, we will **fail** whenever we find a nested middleware but we do **not** include it in the compiler so if the project is using it, it will no longer work. For production we will **fail** too so it will not be possible to build and deploy a deprecated middleware. The error points to a page that should also be reviewed as part of **documentation**.
Aside from the deprecation, this migrates all middleware tests to work with a single middleware. It also splits tests into multiple folders to make them easier to isolate and work with. Finally it ships some small code refactor and simplifications.
## What's in there?
Partially fixes https://github.com/vercel/edge-functions/issues/82
Relates to #36715
Our webpack plugin for middleware leverages static analysis to detect Dyanamic code evaluation in user `_middleware.js` file (and depedencies). Since edge function runtime do not allow them, the build is aborted.
The use of `Function.bind` is considered invalid, while it is legit. A customer using `@aws-sdk/client-s3` reported it.
This PR fixes it.
Please note that this check is too strict: some dynamic code may be in the bundle (despite treeshaking), but may never be used (because of code branches). Since this point is under discussion, this PR adds tests covering some false positives (`@apollo/react-hook`, `qs` and `has`), but does not change the behavior (consider them as errors).
## Notes to reviewer
I looked for test facilities allowing to download the required 3rd party modules. `createNext()` in production context made my day, but showed two issues:
- `cliOutput` is not cleaned in between tests. While clearance during `stop()` would be annoying, I hope that clearance during `start()` is better.
- if `start()` fails while building, the created instance can never be stopped. This is because we don't clear `childProcess` after `build`.

- fix to show the message on overlay of error browser with `next dev`
- fix https://github.com/vercel/next.js/issues/36237
The message is NOT shown when using edge runtime (not middleware) since I cannot find a way to detect a webpack compilation is for edge runtime.

This PR brings some significant refactoring in preparation for upcoming middleware changes. Each commit can be reviewed independently, here is a summary of what each one does and the reasoning behind it:
- [Move pagesDir to next-dev-server](f2fe154c00) simply moves the `pagesDir` property to the dev server which is the only place where it is needed. Having it for every server is misleading.
- [Move (de)normalize page path utils to a file page-path-utils.ts](27cedf0871) Moves the functions to normalize and denormalize page paths to a single file that is intended to hold every utility function that transforms page paths. Since those are complementary it makes sense to have them together. I also added explanatory comments on why they are not idempotent and examples for input -> output that I find very useful.
- [Extract removePagePathTail](6b121332aa) This extracts a function to remove the tail on a page path (absolute or relative). I'm sure there will be other contexts where we can use it.
- [Extract getPagePaths and refactor findPageFile](cf2c7b842e) This extracts a function `getPagePaths` that is used to generate an array of paths to inspect when looking for a page file from `findPageFile`. Then it refactors such function to use it parallelizing lookups. This will allow us to print every path we look at when looking for a file which can be useful for debugging. It also adds a `flatten` helper.
- [Refactor onDemandEntryHandler](4be685c37e) I've found this one quite difficult to understand so it is refactored to use some of the previously mentioned functions and make it easier to read.
- [Extract absolutePagePath util](3bc0783474) Extracts yet another util from the `next-dev-server` that transforms an absolute path into a page name. Of course it adds comments, parameters and examples.
- [Refactor MiddlewarePlugin](c595a2cc62) This is the most significant change. The logic here was very hard to understand so it is totally redistributed with comments. This also removes a global variable `ssrEntries` that was deprecated in favour of module metadata added to Webpack from loaders keeping less dependencies. It also adds types and makes a clear distinction between phases where we statically analyze the code, find metadata and generate the manifest file cc @shuding @huozhi
EDIT:
- [Split page path utils](158fb002d0) After seeing one of the utils was being used by the client while it was defined originally in the server, with this PR we are splitting the util into multiple files and moving it to `shared/lib` in order to make explicit that those can be also imported from client.
This PR fixes a bunch of bugs and it now supports:
- Importing a client component from a nested server component (a.server → b.server → c.client).
- The `export from` syntax in server component (`export { default } from './a.server'`)
- Native modules in server components (currently broken)

Currently we ignore any files that are traced and handled by a webpack loader to prevent including webpack specific files although users may attempt reading files directly using `fs` even if they are handled by webpack so this leverages the new reason types in `@vercel/nft` to only ignore if it is solely imported.

Partially implements #31317 and #31506. There're also some trade-offs made with this PR: since we can't know if a certain runtime will be used or not beforehand, we have to start both runtime compilers (Node.js and Edge) and then generate entrypoints correspondingly.
Note that with this PR, the global runtime is still required to use the per-page runtime.

I took a naive approach and simply added `.env` to the files that need to be copied.
Do we want to include `.env.production` as well? Ref: https://nextjs.org/docs/basic-features/environment-variables#loading-environment-variables
(I haven't tested what happens if the file does not exist on copy.)
Other files like `.env.*local` or `.env.{test,development}` don't make sense to copy.

Production middlewares will only expose env vars that are statically analyzable, as mentioned here: https://nextjs.org/docs/api-reference/next/server#how-do-i-access-environment-variables
This creates some incompatibility with `next dev` and `next start`, where all `process.env` data is shared and can lead to unexpected behavior in runtime.
This PR fixes it by limiting the data in `process.env` with the inferred env vars from the code usage. I believe the test speaks for itself 🕺

After discussing with @sokra, seems that the proposed solution is split in two:
* We need to make sure that the `process` polyfill uses `global.process` if available. This is because middlewares are bundled using `browser` target and therefore `process.env.MY_ENV` gets shimmed into `require('process').env.MY_ENV`.
* Allow `process.env` to be statically analyzed for dependencies so they will be exported to the manifest.

* should fix#33043.
it should not leak into the client runtime

To run middleware we are using a **sandbox** that emulates the web runtime and keeps a module cache. This cache is shared for all of the modules that we run using the sandbox while there are some module-level APIs that must be scoped depending on the module we are running.
One example of this is `fetch` where we want to always inject a special header that indicate the module that is performing the fetch and use it to avoid getting into infinite loops for middleware. For those cases the cached implementation will be the first one that instantiates the module and therefore we can actually get into infinite loops. This is the reason why #31800 is failing.
With this PR we refactor the sandbox so that the module cache is scoped per module name. This means that one execution of a middleware will preserve its cache only for that module so that each execution will still have its own `fetch` implementation, fixing this issue. Also, with this refactor the code is more clear and we also provide an option to avoid using the cache.

1. Align `renderToReadableStream` with `renderToNodeStream`, resolve promise of `NodeWritablePiper` only when `onCompleteShell` is called.
2. update webpack to disable chunk loading for web runtime
Item 1 is the preparation for middleware-ssr-loader. Then we can do the following there
```js
try {
result = await renderToHTML(page)
} catch (e) {
result = await renderToHTML(errorPage)
}
result.pipe(renderResult)
```

When using the web runtime with SSR streaming, this PR significantly improves the build speed for large applications when there're large modules shared by most pages.
With another optimization, `react-dom` will now be excluded in the web runtime build if it's imported in the application. It will only take effect in the client bundle.

This fix the custom 404 is not rendering properly and can’t be built in web runtime when `concurrentFeatures` is enabled. We force 404 page to be rendered outside of middleware ssr. Then it could be the real fallback 404 page in next-server when any routes is not macthed.
Will check 500 related after #31057 is landed.

With this PR we are updating the way we check the usage of `eval` and other dynamic code evaluation (like `new Function`) for middleware. Now instead of simply showing a warning it will behave differently depending on if we are building or in development.
- Development: we replace the dynamic code with a wrapper so that we print a warning only when the code is used. We don't fail in this scenario as it is possible that once the application is built the code that uses `eval` is left out.
- Build: we detect with tree shaking if the code that will be bundled into the middleware includes any dynamic code and in such scenario we make the build fail as don't want to allow it for the production environment.
Closes#30674

- Code splitting should be disabled for the server-web build. Done via `ServerlessPlugin`.
- ~Target can't be `web`, `webworker` is better.~ Using `web` and `es6` for now, still not ideal.

This re-enables minifying middleware chunks as testing on nextjs.org and front shows it is working properly now. The separation of middleware chunks from other client chunks is still kept in this PR to ensure client code doesn't leak into middleware bundles.
