* remove 100 modules form the default modules count
* rename bench_restart -> bench_hydration_cached
* add bench_startup_cached
* run npm install only once per test case and copy the result instead
* use multi-threaded copy
* Run `cached` tests only when `TURBOPACK_BENCH_CACHED` is set
* add `TURBOPACK_BENCH_BENCH` too measure the time it takes to run the
full benchmark (including startup and teardown) instead.
* add `TURBOPACK_BENCH_HEAD` to run non-headless
* add `TURBOPACK_BENCH_DEVTOOLS` to auto open devtools
* retry initial warmup change when it fails to detect that
This should make the benchmarks about 3 times faster... at least on
windows^^
Rebase of vercel/turbo#68, which was merged into a now-closed PR.
Closesvercel/turbo#65.
When configured to use preset-env, this stops turbopack from inserting
dependencies on core-js. It's:
* Buggy/error-prone, at least through swc preset-env:
* https://github.com/vercel/the-three-body/issues/65
* setImmediate "polyfills" always inserted for this nonstandard feature
when
React (scheduler, iirc) does feature detection of it
* Big. Updating the snapshot alone for a test that only used [].includes
resulted in a diff with nearly 4700 line deletions
* Not done by Next.js for modern targets in the past couple of years:
https://twitter.com/timneutkens/status/1234548900272517120
Test Plan: Added [].includes to preset_env snapshot test and verified no
references to core-js are inserted.
This will remove the warning about using `hydrate` instead of
`hydrateRoot`, and fix a mismatch between SSR and CSR when using
styled-jsx (`<style jsx>`).
We can't use the normal `ImportMap` because we stop resolving if looking
up a request within yields a result. However, for module polyfills, we
only need to look up the request when normal resolving fails. Hence the
dichotomy between the `import_map` and the `fallback_import_map`.
In a more modular architecture, we would model this as a stack of three
resolvers:
1. ImportMapResolver
2. DefaultResolver
3. FallbackImportMapResolver
I'm guessing this is what we'll have in the future, but this requires a
bigger refactoring than what I'm comfortable with implementing for now.
This PR also includes the changes in vercel/turbo#12
This optimizes Next.js SSR by marking `react[/*]` and `next[/*]` imports
as externals in Node.js, which means that they will be `require`d
directly instead of bundled.
This optimization reduces the number of modules to analyze on the server
for a single component app from ~1000 (Next.js SSR imports a lot of
modules, including amp-optimizer which includes more) to <10.

add very simple explorer to introspect the graph via `/__turbopack__/`
Allows to "walk" through the content sources and asset graph. Some
assets allows to access inner assets, e. g. from the ecmascript chunk
you can access the entry module asset, so you can go a level deeper.
It works by a `Introspectable` trait which can be implemented by
anything we want to allow the user to inspect. In future the in browser
UI should offer a nice UI to explore your application.
In future we probably also want to add some `metrics` to the
`Introspectable` trait, e. g. to report size of an asset.
This UI is very basic currently, but that works for debugging:
It's important to not create a `cell` outside of the root `source` method as this will create a new cell for each call, which means each `source` will create a separate task, and this bubbles for each cell created in `source`...
This makes the argument to `embed_file!` relative to the package it is invoked from, instead of relative to the file it is invoked from. The latter is closer to how `include_*!` works, but it has a couple of issues:
* Since `file!` returns a path relative to the workspace, it requires knowing the full path to the workspace. However, this is undefined when the package is compiled from outside of the workspace (e.g. as a dependency of another package).
* Procedural macros don't have access to the path of the file where they were originally invoked [(although we could get it with #[feature(proc_macro_span)])](https://doc.rust-lang.org/proc_macro/struct.Span.html), which means that an `embed_dir` macro would not be able to be relative to the invoker file anyway. So this makes things more consistent for such a (to be implemented) macro.
This is a very simplified version of what Next.js does. It adds support for `App` and page components defining `getInitialProps`.

This updates all of our Issues to have a consistent display, and changes the way we display source code and debug-level details. In particular, this makes the following changes:
1. Cleans up the title/description of existing issues
- We were filling the `title` field with too much information, because the `desccription` field wasn't always shown.
1. Always displays the `description`
- This used to be hidden behind the `--detail` flag
1. Always displays the code frame of the issue, if it exists
- This used to be hidden behind the `--detail` flag
1. Fixes the `context` (file path) to display the relative path to the file
- It was hardcoded to the FS string used by turbotrace
1. Creates a new `detail` function which can provide debug-level information about the internal Rust state
- This is not shown by default, user must pass `--detail` flag
The format for a rendered issue roughly matches:
```
${SEVERITY} [${CATEGORY}]
${CONTEXT}
${TITLE}
${CODE FRAME}
${DESCRIPTION}
${DETAIL}
```
Where
- `SEVERITY` is error/warning/etc
- `CATEGORY` is a self-defined string for the phase of the compiler (eg, "parsing", "running")
- `CONTEXT` is a file path to the offending file
- `TITLE` is a short (single-line) title
- `CODE_FRAME` is an optional position that generated the issue, which will display a few context lines and highlight the offending span of code
- `DESCRIPTION` is a longer (multi-line) message that describes the issue, and what to do about it
- `DETAIL` is a (by default not shown) fully detailed, debug-level, message providing insights into the internal state of Rust
This adds preliminary support for pages/_document. The API is more complex than pages/_app, so this required a few more things in order to work.
Right now, our `next/document` shim does much, much less than the original. We will eventually have to figure out whether we should distribute our own module, or find a way to reuse Next.js' internals. There's *a lot* of stuff in there so the second option is probably best.
This adds preliminary support for pages/_app. There's still some work to do here to support things like `App. getInitialProps`, etc., but that will come in later PRs. I've created issues for these for now.
One issue remaining is that renaming `pages/_app.js` does not switch to the default _app asset. The server needs to be restarted for this to happen. Similarly, adding an _app.js file does not switch from the default asset to it. I'm guessing there's something wrong with the way I set up the import mappings, and they aren't being invalidated properly?

remove context_path from AssetContext
remove most with_* methods from AssetContext
add ResolveOrigin trait
use ResolveOrigin to pass along context path and context for resolving
ecmascript and css module assets implement ResolveOrigin
Noteable change: Many places use `origin_path` instead of `context_path` which means it points to the issuer module path instead of the issuer module directory.
Closesvercel/turbo#440
This uses swc's preset_env to automatically downlevel code according to the environment's browser targets, and sets next-dev to use a limited, modern target.
To do:
* [x] Add snapshot test
* [x] turbotrace test failures — looks like this has something to do with the Buffer module? Hitting swc's "multiple constructors" not implemented: f655488cfa/crates/swc_ecma_transforms_compat/src/es2015/classes/mod.rs (L545)
* [x] ~Benchmark downleveling node_modules (probably on front) and make a decision re: downleveling everything vs. just workspaces~ Filed as vercel/turbo#457
Wrapper is a bit of a weird name since it's not actually wrapping the existing asset. Actually it's just a virtual asset with a path below the existing path.
