BREAKING CHANGE
Since `next export` has been printing a deprecation warning since https://github.com/vercel/next.js/pull/47376, its safe to remove in semver-major.
The upgrade path is to simply add `output: 'export'` in `next.config.js` - everything will continue to work the same.
This config greatly improves the `next dev` experience today. And in the future, it will improve performance of `next build` because we no longer need to do two passes (build then export).
This PR fixes a memory leak when using `next dev` where on HMR, we would always retain the memory associated with the old VM instance, leading to pretty egregious usage of RAM after only a few edits.
The leak itself comes from methods like `setTimeout` and `setInterval` capturing the context in which they were called and somehow never releasing, even if the timeout happened, when running in a Node.js `vm`. This is probably a Node.js bug.
The fix consists of taking ownership of all timeouts and clearing them ourselves manually at the end of each VM lifecycle.
Tested manually:
- hello world Next.js app with edge runtime
- triggered hmr 10 times
- memory usage
- base: 400MB
- before: 800MB
- after: 400MB
This change makes sure that the iv of AES-GCM encryption is cryptographically random on each request. Also added a constant prefix as some kind of checksum to ensure the data is not damaged (e.g. wrong key is being used).

Refactoring the webpack-config.ts file to no longer have all aliases defined, instead they are in a separate file which should make refactoring these to use them in Turbopack simpler.
### What?
If there's a static asset with edge runtime config, turbopack will bail with
```
⨯ ModuleBuildError: Code generation for chunk item errored
An error occurred while generating the chunk item [project]/test/e2e/app-dir/metadata/app/icon.svg (static, edge rsc)
Caused by:
- expected output_root to contain asset path
Debug info:
- An error occurred while generating the chunk item [project]/test/e2e/app-dir/metadata/app/icon.svg (static, edge rsc)
- Execution of <DevChunkingContext as ChunkingContext>::asset_url failed
- expected output_root to contain asset path
```
Since we creates chunking context for the edge with different output_root and asset_root, by using asset_root to be client_root. The other places creating context with `DevChunkingContext` don't do this, PR simply adjusting root to be output_root.
For the server's chunking context it actually accepts client_root and set the asseturl with client root instead. However not sure if that's what we want with devchunkingcontext.
This is part of metadata fixes for the test; however edge rendering still doesn't work so test doesn't pass yet.
Closes WEB-1798
### What?
- fixes test 17553c5e25/test/e2e/app-dir/metadata/metadata.test.ts (L487)
The way next.js collects static metadata is read static metadata, and then read layout metadata to merge multiple metadatas into a single layout path (17553c5e25/packages/next/src/lib/metadata/resolve-metadata.ts (L347-L352))
When turbopack creates LoaderTree for the corresponding directory tree, it extracts `page` but skips metadata in result there are orphan components that have a metadata doesn't have layout metadata, as well as a component have a layout doesn't have metadata. Latter is being rendered as a page (since it have correct layout), which eventually falls back to the default metadata instead.
PR trickles down the metadata when extracting page (creating a new component with `page`) to consolidates those.
Also PR expands Metadata to have base_page property to capture where it has been originally exists, as we clone down metadata then do `fillMetadataSegment` against the current page where LoaderTree is being created it creates a wrong relative path. For example, currently
```
/icon.svg
- opengragph/
- static -> path being `/opengraph/.../icon.svg` instead of `/icon.svg`
```
When recursively traverse directory tree, capture each components with corresponding base_page to calculate instead.
Unfortunately this doesn't make pass all of the metadata tests; there are lot to dig more. Would like to scope PR in a reasonable size.
Closes WEB-1795
When using server actions on an unsupported version of Node, you might see the following errors:
> NotSupportedError: multipart/form-data not supported
Support in Undici was landed in 5.11.0 which made it into Node v18.11.0
> TypeError: e._formData.forEach is not a function
Earlier versions of v18 (such as 18.0.0) did not have a `.forEach` implementation on FormData
This throws a better error before the user can get to the point of seeing these more confusing errors.
Closes NEXT-1658
Fixes#55932
This PR implements encryption and decryption for Server Action bound values that are from the closure level. Explicit `.bind` values, function arguments and module-level values are NOT handled.
### Compiler
The compiler now groups all closure bound values to an array which gets wrapped with `encrypt`. And then inside the action body, it prepends an expression to recreate the values via `await decrypt`.
Since closure-closed variables will only exist on the server layer, the encryption utility has `"server-only"` annotated.
### Encryption
During build time, a private AES-GCM encryption key is randomly generated and stored in the built server manifest. Before encrypting/decrypting, an extra round of Flight server and client will be used to serialize/deserialize the value.
When encrypting, a salt that contains the action ID is provided to prevent replay attack towards different API endpoints. The encryption key can be overridden via the `NEXT_SERVER_ACTIONS_ENCRYPTION_KEY` env variable so it can be built on multiple machines on scale.
A global singleton for storing the client reference manifest was made for Flight's serialization/deserialization as that might happen outside of rendering.
After encryption, we then serialize the ArrayBuffer as Base64 to send it to the client.

### What?

### How?
By checking the repository name and comparing it with the main

This PR fixes the passing of the `--inspect` option when calling Next.js with it. It's still not great because you need to target the next file in node_modules directly but I'll add a `next --inspect` option in the future.
This:
- Uses `isServer` to use the appropriate Turbopack `FileSystem` when
creating `FileSystemPath`s
- Properly uri decodes path segments originating from `file://` uris
- Correctly reads chunks starting at the project path instead of the
root path
Closes WEB-1815

The asset context is a better place to store the layer, because it's
affected by transitions unlike the chunking context
This PR also removes a bunch of unused code
### Why?
See https://github.com/vercel/turbo/pull/6237 for the rationale
Also needs to wait for that PR to be merged
Closes NEXT-1814

### Description
- Splits the generated code of the `next-edge-ssr-loader` out into 2 templates
- This PR also adds support for optional imports in templates
Closes WEB-1761
### What?
`globalThis.ReadableStream` and `globalThis.WriteableStream` has been exposed since Node.js 18, which is our new default requirement. (#56943)
### Why?
This simplifies the code and might result in slightly better performance.
### How?
Drop any checks of `globalThis` properties that are always defined now.
