[Compare
Source](https://redirect.github.com/CodSpeedHQ/codspeed-node/compare/v5.4.0...v5.5.0)

### Highlights

We are introducing `@codspeed/playwright`, for walltime benchmarking and
profiling of end to end browser applications through playwright.

Here's an example usage, but head to the
[docs](https://codspeed.io/docs/benchmarks/nodejs/playwright) for more
information

```typescript
import { bench, type Page } from "@&#8203;codspeed/playwright-plugin";
import electronExecutable from "electron";
import path from "node:path";
import { fileURLToPath } from "node:url";

const __dirname = path.dirname(fileURLToPath(import.meta.url));
const appRoot = path.resolve(__dirname, "..");

async function waitUntilSettled(page: Page): Promise<void> {
  await page.waitForFunction(() => {
    const main = document.getElementById("main");
    return !!main && !main.classList.contains("loading");
  });
}

await bench(
  "inbox-search-archive-threads",
  async ({ page }) => {
    await page.fill("#search", "update");
    await waitUntilSettled(page);

    await page.click("#select-visible-btn");
    await page.click("#archive-btn");
    await waitUntilSettled(page);

    await page.click('#sidebar nav button[data-view="threads"]');
    await waitUntilSettled(page);
  },
  {
    target: {
      kind: "electron",
      appPath: path.join(appRoot, "out/main/index.js"),
      cwd: appRoot,
    },
    beforeRound: async ({ page }) => {
      page.setDefaultTimeout(180_000);
      await page.waitForSelector("#main");
      await waitUntilSettled(page);
    },
  },
);
```

Note: this plugin is only compatible with the walltime instrument.

Boshen 963146f4b6 refactor(semantic): use SemanticBuilder presets at remaining call sites (#23057)
Use the `SemanticBuilder::new_linter()` preset at linter call sites that built semantic with ad-hoc `new().with_cfg(true)`-style chains, so they build semantic the same way the linter does instead of replicating its options by hand.

- linter test helpers: `disable_directives`, `utils/{regex,comment,jest,react}`
- playground's lint path

Behaviour-neutral; all linter tests pass.

Boshen 336413bf5d refactor(semantic): use new_linter/new_compiler presets at callsites (#23037)
Replaces ad-hoc `SemanticBuilder::new().with_*()` chains with the `new_linter()` / `new_compiler()` presets where the preset already expands to the exact same option set, so the config lives in one place.

- linter example + linter benchmark → `new_linter()` (cfg + class table + syntax)
- semantic benchmark, cfg example, integration test util → `new_compiler()` (syntax)

Behavior-neutral — each preset matches the options the callsite set by hand. Carved out of the larger store-optional refactor so it can land independently on `main` first.

Boshen 324c8ae137 refactor(semantic): add SemanticBuilder::new_compiler / new_linter presets (#23019)
## Summary

Adds two named constructor presets to `SemanticBuilder` that bake in the options each use case needs, so the configuration lives in one place instead of being repeated at call sites:

- **`SemanticBuilder::new_compiler()`** — compiler pipeline. Enables syntax-error checking; leaves linter-only analyses (control flow graph, class table) off.
- **`SemanticBuilder::new_linter()`** — linter. Enables syntax-error checking, the control flow graph, and the class table.

The presets are applied at the real pipeline entry points:
- `new_linter()` → the linter service build.
- `new_compiler()` → `oxc::Compiler`, and the napi parser/transform bindings.

Everywhere else keeps `SemanticBuilder::new()` and turns on only the features it needs (mangler, minifier, formatter, transformer plugins, examples, tests, ...). Individual options can still be overridden after a preset (e.g. the linter service overrides `check_syntax_error` with its runtime flag).

Behavior is preserved at every migrated site. Node-store access is intentionally untouched in this PR.

## Verified

- Builds across the affected crates + napi; clippy clean; `oxc_linter` tests pass; full `cargo coverage` with no snapshot changes.

leaysgur 5778a2dfb5 refactor(formatter_core): purify core and define rules (#22952)
The Printer never consumes these; they belong with each language formatter.

- Evict `Quote` (each formatter owns `QuoteStyle`)
  - `normalize_string` takes a quote byte
- Evict `Expand` / `BracketSpacing` / `TrailingCommas` into oxc_formatter and oxc_formatter_json
- JSON's `TrailingCommas` is now two-variant (`Always`/`Never`)
  - collapse Prettier's `all`/`es5` at each translation layer
- Rename `util/` -> `spec/` (pure shared helpers)
- Split `SourceText`: mechanical access stays in core, JS/TS lexis moves to `SourceTextExt`
- Drop the `oxc_syntax` dependency from core

All behaviros, Prettier conformance are unchanged.

Dunqing 188b9e6b43 chore(bench): swap cal.com.tsx for excalidraw App.tsx everywhere (#22895)
## Summary

Follow-up to #22590. That PR replaced the synthetic `cal.com.tsx` fixture — a concatenation of Next.js pages that declares top-level names 70–113× and emits thousands of redeclaration diagnostics, inflating semantic `sys_allocs` — with excalidraw's real, single-file `App.tsx`. But it only touched `TestFiles::complicated()` (used by `track_memory_allocations`).

This applies the same swap to every remaining benchmark that still used `cal.com.tsx`, and unifies **all** excalidraw `App.tsx` references on one pin (`f6d85bc8`):

| File | Change |
| --- | --- |
| `tasks/common/src/test_file.rs` | `minimal()` (feeds every `tasks/benchmark` criterion bench): `cal.com.tsx` → `App.tsx@f6d85bc8`. `formatter()` re-pinned `@v0.18.0` → `@f6d85bc8` |
| `napi/parser/bench.bench.js` | parser benchmark fixture → `App.tsx@f6d85bc8` |
| `napi/parser/test/parse-raw.test.ts` | bench-fixture list + size comment → `App.tsx@f6d85bc8` |
| `tasks/benchmark/benches/semantic.rs` | rewrote the now-false "`cal.com.tsx` has many errors" comment |
| `crates/oxc_ast/src/serialize/mod.rs` | removed the stale `cal.com.tsx` row from the capacity-ratio doc table |

## Why a single pin

`get_source_text` caches downloads by the last URL segment only (`App.tsx`). With two different pins live, a single `cargo bench` run would download both into the same `target/App.tsx` and silently bench whichever landed first. Re-pinning `formatter()` to `f6d85bc8` removes that collision — and the pre-existing latent one between `cargo bench` (`@v0.18.0`) and `cargo allocs` (`@f6d85bc8`).

## Notes

No committed snapshots change: these fixtures feed only timing benches and a `programRaw.toEqual(programStandard)` self-consistency test; the snapshotted `complicated()` / `minifier()` sets are untouched.

leaysgur 705c0e969b refactor(formatter): introduce text-in public APIs (#22872)

- Add text-in `format` and `format_fragment`, also `format_program`, `parse_for_format` and the `FragmentContext` enum
  - Parse options, JSX enabling, js-in-xxx context aware handlings are applied internally
  - Make the `Formatter` struct and AST/IR primitives crate-internal
- Fold `get_parse_options` / `enable_jsx_source_type` and the `service` module into `parse_for_format`

leaysgur c323187f37 refactor(formatter): Split oxc_formatter and oxc_formatter_core (#22611)
Split `oxc_formatter` into:

- `oxc_formatter(_js)`: JS/TS specific formatter, comment handling, sortImports, jsdoc, etc
- `oxc_formatter_core`: Language agnostic IR, printer, etc

The naming convention is different from Biome or Ruff (they do not have `_core`, and `_formatter` is equivalent to the core), but this is because in Oxc, items without `_js` are the default.

As a basic task, I have added `Context` as a generic to all relevant parts to ensure support for multiple languages.

There might still be other components that could be refactored into the core, but I would like to finish them as I implement support for other languages.

Also moved some shared utilities to the core in advance.

Boshen e857b0cfe5 feat(napi/minify): expose legalComments option and result (#20370)
## Summary

- Add `legalComments` and `legalCommentsPath` fields to the NAPI `CodegenOptions` struct, accepting `"none"`, `"inline"`, `"eof"`, `"linked"`, `"external"`
- Add `legalComments: Vec<String>` to `MinifyResult`, populated from `CodegenReturn::legal_comments` when using `"linked"` or `"external"` mode
- Replace the `From<&CodegenOptions>` impl with a `to_codegen_options()` method that validates and maps string values to `oxc_codegen::LegalComment` variants

This enables downstream consumers (e.g. `oxc-webpack-plugin`) to use oxc's built-in legal comment extraction instead of regex-based post-processing.

Kyle Cannon ee659b6785 feat(transformer/legacy-decorator): add strictNullChecks option for nullable-union design:type (#22266)
## Summary

Adds a `strictNullChecks` field to `DecoratorOptions` (default `true`)
that
controls whether `null` and `undefined` are elided from union
`design:type`
metadata. The default preserves tsc strict semantics (`T | null` →
`Object`);
setting `strictNullChecks: false` matches
babel-plugin-transform-typescript-metadata
and tsc with `--strictNullChecks=false`, emitting the underlying
primitive
(`T | null` → `String` when `T = string`).

Originally this PR unconditionally elided null/undefined. Per @Dunqing's
review, it's now opt-in so the default-strict behaviour is preserved.

## Motivation

When `strictNullChecks` is off, tsc emits the constructor of the
underlying
primitive. babel-plugin-transform-typescript-metadata always elides null
and
undefined regardless of tsconfig. Downstream consumers (NestJS Swagger,
class-validator, TypeORM, AutoMapper) treat `Object` as "no metadata"
and
silently drop fields, so users with `strictNullChecks: false` (common in
older codebases) get worse behaviour under OXC than under tsc/babel.

## Implementation

```rust
pub struct DecoratorOptions {
    pub legacy: bool,
    pub emit_decorator_metadata: bool,
    #[serde(default = "default_as_true")]
    pub strict_null_checks: bool, // default true
}
```

Threaded through `Decorator::new(options) →
LegacyDecorator::new(&options) →
LegacyDecoratorMetadata::new(&options)` (matching the established
`TypeScript::new(&TypeScriptOptions)` precedent), and gated in
`serialize_union_or_intersection_constituents`:

```rust
TSType::TSNullKeyword(_) | TSType::TSUndefinedKeyword(_)
    if !is_intersection && !self.strict_null_checks => continue,
```

Mirrored at the napi binding (`napi/transform/src/transformer.rs`) so
direct
Node consumers can flip it the day this lands. Consumers that wire
tsconfig
(rolldown, bundlers) can forward `compilerOptions.strictNullChecks` to
it.

## Behaviour matrix

| Source | `strictNullChecks: true` (default) | `strictNullChecks:
false` |
|---|---|---|
| `string \| null` | `Object` (matches tsc strict, current behaviour) |
`String` (matches babel, tsc non-strict) |
| `number \| undefined` | `Object` | `Number` |
| `boolean \| null \| undefined` | `Object` | `Boolean` |
| `null \| undefined` | `void 0` | `void 0` |
| `string \| number` | `Object` | `Object` (distinct primitives) |
| `string & null` | `Object` | `Object` (intersection unchanged) |

## Test plan

- [x] 7 unit tests in `tests/integrations/decorator_metadata.rs`
covering
`T | null` under both `strictNullChecks: true` (emits `Object`, current
  behaviour) and `strictNullChecks: false` (emits primitive), plus
`T | undefined`, `T | null | undefined`, the `null | undefined`
void-only
case, the `string | number` distinct-primitive case (still `Object`),
and
  the intersection-with-null regression
- [x] New conformance fixture `oxc/metadata/nullable-union/` with its
own
  `options.json` setting `strictNullChecks: false`
- [x] `cargo test -p oxc_transformer` passes (31 unit + 11 integration)
- [x] `cargo run -p oxc_transform_conformance` shows 0 regressions;
baseline
  fixtures still pass plus the new `nullable-union`
- [x] `cargo fmt -p oxc_transformer -p oxc_transform_napi` and
  `cargo clippy --tests --no-deps` clean

[Compare Source](https://redirect.github.com/microsoft/playwright/compare/v1.59.1...v1.60.0)

#### 🌐 HAR recording on Tracing

[tracing.startHar()](https://playwright.dev/docs/api/class-tracing#tracing-start-har) / [tracing.stopHar()](https://playwright.dev/docs/api/class-tracing#tracing-stop-har) expose HAR recording as a first-class tracing API, with the same `content`, `mode` and `urlFilter` options as `recordHar`. The returned [Disposable](https://playwright.dev/docs/api/class-disposable) makes it easy to scope a recording with `await using`:

```js
await using har = await context.tracing.startHar('trace.har');
const page = await context.newPage();
await page.goto('https://playwright.dev');
// HAR is finalized when `har` goes out of scope.
```

#### 🪝 Drop API

New [locator.drop()](https://playwright.dev/docs/api/class-locator#locator-drop) simulates an external drag-and-drop of files or clipboard-like data onto an element. Playwright dispatches `dragenter`, `dragover`, and `drop` with a synthetic \[DataTransfer] in the page context — works cross-browser and is great for testing upload zones:

```js
await page.locator('#dropzone').drop({
  files: { name: 'note.txt', mimeType: 'text/plain', buffer: Buffer.from('hello') },
});

await page.locator('#dropzone').drop({
  data: {
    'text/plain': 'hello world',
    'text/uri-list': 'https://example.com',
  },
});
```

#### 🎯 Aria snapshots

- [expect(page).toMatchAriaSnapshot()](https://playwright.dev/docs/api/class-pageassertions#page-assertions-to-match-aria-snapshot) now works on a [Page](https://playwright.dev/docs/api/class-page), in addition to a [Locator](https://playwright.dev/docs/api/class-locator) — equivalent to asserting against `page.locator('body')`.
- New `boxes` option on [locator.ariaSnapshot()](https://playwright.dev/docs/api/class-locator#locator-aria-snapshot) / [page.ariaSnapshot()](https://playwright.dev/docs/api/class-page#page-aria-snapshot) appends each element's bounding box as `[box=x,y,width,height]`, useful for AI consumption.

#### 🛑 test.abort()

New [test.abort()](https://playwright.dev/docs/api/class-test#test-abort) aborts the currently running test from a fixture, hook, or route handler with an optional message. Use it when you have detected an unrecoverable misuse and want to fail the test right away:

```js
test('does not publish to the shared page', async ({ page }) => {
  await page.route('**/publish', route => {
    test.abort('Tests must not publish to the shared page. Use the `clone` option.');
    return route.abort();
  });
  // ...
});
```

#### New APIs

##### Browser, Context and Page

- Event [browser.on('context')](https://playwright.dev/docs/api/class-browser#browser-event-context) — fired when a new context is created on the browser.
- [BrowserContext](https://playwright.dev/docs/api/class-browsercontext) now mirrors lifecycle events from its pages: [browserContext.on('download')](https://playwright.dev/docs/api/class-browsercontext#browser-context-event-download), [browserContext.on('frameattached')](https://playwright.dev/docs/api/class-browsercontext#browser-context-event-frame-attached), [browserContext.on('framedetached')](https://playwright.dev/docs/api/class-browsercontext#browser-context-event-frame-detached), [browserContext.on('framenavigated')](https://playwright.dev/docs/api/class-browsercontext#browser-context-event-frame-navigated), [browserContext.on('pageclose')](https://playwright.dev/docs/api/class-browsercontext#browser-context-event-page-close), [browserContext.on('pageload')](https://playwright.dev/docs/api/class-browsercontext#browser-context-event-page-load).

##### Locators and Assertions

- New option `description` in [page.getByRole()](https://playwright.dev/docs/api/class-page#page-get-by-role) / [locator.getByRole()](https://playwright.dev/docs/api/class-locator#locator-get-by-role) / [frame.getByRole()](https://playwright.dev/docs/api/class-frame#frame-get-by-role) / [frameLocator.getByRole()](https://playwright.dev/docs/api/class-framelocator#frame-locator-get-by-role) for matching the [accessible description](https://www.w3.org/TR/wai-aria-1.2/#dfn-accessible-description).
- New option `pseudo` in [expect(locator).toHaveCSS()](https://playwright.dev/docs/api/class-locatorassertions#locator-assertions-to-have-css) reads computed styles from `::before` or `::after`.
- New option `style` in [locator.highlight()](https://playwright.dev/docs/api/class-locator#locator-highlight) applies extra inline CSS to the highlight overlay, plus new [page.hideHighlight()](https://playwright.dev/docs/api/class-page#page-hide-highlight) to clear all highlights.

##### Network

- [webSocketRoute.protocols()](https://playwright.dev/docs/api/class-websocketroute#web-socket-route-protocols) returns the WebSocket subprotocols requested by the page.
- New option `noDefaults` in [browserType.connectOverCDP()](https://playwright.dev/docs/api/class-browsertype#browser-type-connect-over-cdp) disables Playwright's default overrides on the default context (download behavior, focus emulation, media emulation), so attaching to a user's daily-driver browser doesn't disturb its state.

##### Errors and Reporting

- New [webError.location()](https://playwright.dev/docs/api/class-weberror#web-error-location) mirrors [consoleMessage.location()](https://playwright.dev/docs/api/class-consolemessage#console-message-location).
- [consoleMessage.location()](https://playwright.dev/docs/api/class-consolemessage#console-message-location) now exposes `line` / `column` properties (`lineNumber` / `columnNumber` are deprecated).
- New [testInfoError.errorContext](https://playwright.dev/docs/api/class-testinfoerror#test-info-error-error-context) surfaces additional diagnostic context, such as the aria snapshot of the receiver at the time of an `expect(...)` matcher failure.
- [reporter.onError()](https://playwright.dev/docs/api/class-reporter#reporter-on-error) now receives a `workerInfo` argument with details about the worker for fixture teardown errors.

##### Test runner

- New `{testFileBaseName}` token in [testProject.snapshotPathTemplate](https://playwright.dev/docs/api/class-testproject#test-project-snapshot-path-template) — file name without extension.
- Test runner now errors when a config tries to override a non-option fixture, and rejects `workers: 0` or negative values.

#### 🛠️ Other improvements

- HTML reporter:
  - `npx playwright show-report` accepts `.zip` files directly — no need to unzip first.
  - Steps that contain attachments inside nested children show an indicator on the parent step.
  - The `repeatEachIndex` is shown in the test header when non-zero.
- Trace Viewer adds a pretty-print toggle for JSON / form request and response bodies in the network details panel.

#### Breaking Changes ⚠️

- Removed long-deprecated APIs:
  - `Locator.ariaRef()` — use the standard [locator.ariaSnapshot()](https://playwright.dev/docs/api/class-locator#locator-aria-snapshot) pipeline.
  - `handle` option on `BrowserContext.exposeBinding` and `Page.exposeBinding`.
  - `logger` option on `BrowserType.connect` and `BrowserType.connectOverCDP` — use [tracing](https://playwright.dev/docs/trace-viewer) instead.
  - Context options `videosPath` / `videoSize` — use `recordVideo` instead.

#### Browser Versions

- Chromium 148.0.7778.96
- Mozilla Firefox 150.0.2
- WebKit 26.4

This version was also tested against the following stable channels:

- Google Chrome 147

overlookmotel e3b0d54556 refactor(napi/parser, linter/plugins): improve safety of raw transfer interface (#22424)
Add a check that the input passed to raw transfer parser implementations is valid - both in `napi/parser` and in the raw transfer implementation used in Oxlint's `RuleTester`.

Check that `source_start` and `source_len` which are passed from JS side are within bounds of the active region of the `Arena`. This check is not strictly necessary - it's part of the safety contract, and is enforced on JS side - but it's critical as the setup of the `Arena` on Rust side depends on the accuracy of these values. If they were wrong, it could lead to reading/writing out of bounds. The check is cheap, so it seems worthwhile - safety trumps the tiny perf impact here.

The 3rd invariant of these functions is that the bytes in the buffer between `source_start` and `source_start + source_len` represent a valid UTF-8 string. Here a full runtime check isn't appropriate, as it would involve scanning and validating the whole source text string (expensive). But _do_ enable the full check in debug builds (used by raw transfer parser tests, and Oxlint conformance tests).

overlookmotel c2c8f806f9 refactor(napi/parser): raw transfer store source text at end of buffer (#22392)
Oxlint's raw transfer implementation stores the source text at end of the buffer. Prior to this PR `napi/parser` stored source text at the start of the buffer.

Bring `napi/parser` into line with Oxlint, by also storing source text at end of the buffer.

Making all versions of raw transfer that we use align with each other removes complication (all versions now have the same implementation of `deserializeStr`) and also removes some fragile code where it'd be easy to accidentally trigger UB (see the updated comments in `arena/fixed_size/windows.rs` and `arena/alloc_impl.rs`).

Unfortunately, storing source at end of buffer is slightly less efficient than storing it at the start. We'll switch all implementations to storing source at start of buffer when we move to storing all strings (source text and all other strings) together in a single contiguous block. But in meantime, this slight inefficiency is outweighed by the gain in safety.

NullVoxPopuli 429deac502 fix(napi/parser): export visitorKeys from wasm entrypoint (#21996)
Fixes #21995 

Unblocks
- https://github.com/sxzz/ast-explorer/pull/263

Why?
- getting the actual list of visitorKeys provides an optimization for
tools like zimmerframe, which will `walk` over only the things specified
in the visitorKeys list -- helping prevent accidental recursive
visiting, which can happen when a tree adds parent referencs

overlookmotel 99eef72e2d refactor(allocator, linter/plugins, napi/parser): store raw transfer metadata within Arena chunk (#21869)
Large change to how raw transfer stores metadata about the allocations it uses.

Previously the two metadata structures `RawTransferMetadata` and `FixedSizeAllocator` after the chunk's `ChunkFooter`.

This had a few problems:

1. It was confusing and unwieldy - a recipe for bugs.
2. `ChunkFooter`'s memory was exposed on JS side - a bit unsafe as altering bytes in this region could easily trigger UB.
3. It entwined `Arena` (which is just the thing that allocates) with the details of exactly _what_ raw transfer allocates.
4. Imposed annoying alignment requirements, because `ChunkFooter` must be aligned on 16, and so anything after it must ensure it doesn't break that invariant.

Old layout:

```
                                                        WHOLE BLOCK - aligned on 4 GiB
<-----------------------------------------------------> Allocated block (`BLOCK_SIZE` bytes)

                                                        ALLOCATOR
<----------------------------------------->             `Allocator` chunk (`CHUNK_SIZE` bytes)
                                     <---->             `ChunkFooter` (aligned on 16)
<----------------------------------->                   `Allocator` chunk data storage (for AST)
                                                        (`ACTIVE_SIZE` bytes)

                                                        METADATA
                                           <---->       `RawTransferMetadata`
                                                 <----> `FixedSizeAllocatorMetadata`

                                                        BUFFER SENT TO JS
<----------------------------------------------->       Buffer sent to JS (`BUFFER_SIZE` bytes)
```

This PR moves `RawTransferMetadata` and `FixedSizeAllocatorMetadata` into the chunk itself. New layout:

```
                                                        WHOLE BLOCK - size 2 GiB - 16, aligned on 4 GiB
<-----------------------------------------------------> Allocated block (`BLOCK_SIZE` bytes)

                                                        ARENA
<-----------------------------------------------------> Chunk (fills whole block)
<-------------------------------------->                Allocatable region for AST (`ACTIVE_SIZE` bytes)
                                        <--->           `RawTransferMetadata`
                                             <--->      `FixedSizeAllocatorMetadata`
                                                  <---> `ChunkFooter` (aligned on 16, last in block)

                                                        BUFFER SENT TO JS
<------------------------------------------->           Buffer sent to JS (`BUFFER_SIZE` bytes)
```

`FixedSizeAllocatorMetadata` and `ChunkFooter` are no longer in the region which is shared with JS side. As far as `Arena` is concerned, they're now just some data (like any other data) which is allocated in the arena.

Also:

- Introduce more consistency to the naming of constants which specify the size and position of these various data structures in the arena.
- Add more const assertions to ensure everything is laid out and aligned as it should be.

anthropic-code-agent 245273ef0a feat(napi/playground): add optimizeEnums and optimizeConstEnums options (#21815)
## Summary
This PR adds `optimizeEnums` and `optimizeConstEnums` options to the playground's transformer configuration, enabling TypeScript enum optimization features that are already available in the transformer.

## Changes
- Added `optimize_enums: bool` and `optimize_const_enums: bool` fields to the `OxcTransformerOptions` struct in `napi/playground/src/options.rs`
- Updated `apply_transformations` method in `napi/playground/src/lib.rs` to apply these options to `options.typescript.optimize_enums` and `options.typescript.optimize_const_enums`

## Reference
Resolves https://github.com/oxc-project/oxc/blob/d1cf22efc2bc9cf9fa82e887c34965d2ce3004c3/napi/playground/src/options.rs#L59

These options enable:
- `optimize_enums`: Optimize regular (non-const) enums by inlining their member accesses at usage sites when the member value is statically known
- `optimize_const_enums`: Optimize const enums by inlining their values at usage sites and removing the enum declaration

overlookmotel 9fa362eac7 perf(napi/parser): do not generate tokens except in tests (#21811)
#19885 added support for tokens in `oxc-parser`, but only via raw transfer and behind an undocumented `experimentalTokens` option. It's currently only used in tests for the purpose of conformance testing.

This slowed down `oxc-parser` a little (very little as the difference in execution time on Rust side is dwarfed by the cost of JSON transfer).

The worse effect is that it caused a large binary size increase in Rolldown (https://github.com/rolldown/rolldown/issues/9166) because Rolldown re-exports `napi/parser`'s Rust code, which meant that Rolldown now contains 2 versions of Oxc's parser with different `ParserConfig`s, leading to the entire parser being compiled and included in the binary twice.

Fix this by introducing a Cargo feature `tokens` on `napi/parser` crate. Only when `tokens` feature is enabled is a `ParserConfig` which generates tokens used. When disabled (the default), the default `ParserConfig` which does not produce tokens is used.

Enable the `tokens` feature only in tests.

overlookmotel a7521cb122 refactor(linter/plugins, napi/plugins): use constant for arena alignment from Allocator (#21797)
Refactor.

Don't hard-code the minimum alignment of `Arena` chunks in `apps/oxlint` and `napi/parser`. Get the value from a property on `Allocator`. This will avoid this code getting out of sync if the value changes in future.

Also rename the vars `BUMP_ALIGN` to `ARENA_ALIGN`, as the arena type is now called `Arena` not `Bump`, and update some comments which were out of date.

overlookmotel 502e804ffa perf(ast)!: reduce size of TSTypePredicateName (#21711)
#21653 revealed that `TSTypePredicateName` has an unboxed variant `This`.

Before the introduction of `NodeId` fields, this was fine as `TSThisType` contained only a `Span` (8 bytes). But with `NodeId` field added, it's 16 bytes, which makes `TSTypePredicateName` larger too - 24 bytes.

Box `TSThisType` in this variant, bringing `TSTypePredicateName` back down to 16 bytes.

This also has the side-effect of making `TSTypePredicateName`'s `node_id`, `span`, and `span_mut` methods branchless.

루밀LuMir e4cea255b7 docs(transform): use the node: namespace in the example (#19998)
Hi,

This PR simply updates the documentation example in
`napi/transform/README.md` to use the `node:` namespace when importing a
Node.js built-in module.

As far as I know, the `node:` namespace prefix for built-in modules was
introduced in Node.js `14.18.0` and `16.0.0`, so it should work with the
current Node.js supported version range.


https://github.com/oxc-project/oxc/blob/6245c5629f2ca3bbbfbaffd1400fad06cc23d659/napi/transform/package.json#L87-L89

Also, it appears that the other source files already use it when
importing Node.js built-in modules.


https://github.com/oxc-project/oxc/blob/6245c5629f2ca3bbbfbaffd1400fad06cc23d659/napi/transform/scripts/patch.js#L1-L2


https://github.com/oxc-project/oxc/blob/6245c5629f2ca3bbbfbaffd1400fad06cc23d659/napi/transform/webcontainer-fallback.cjs#L1-L2

Please let me know if there's anything wrong with this change!

Dunqing f5deb55ea6 feat(napi/transform): expose optimizeConstEnums and optimizeEnums options (#21388)
Surface the TypeScript transformer's `optimize_const_enums` and
`optimize_enums` options through the napi bindings so JavaScript
consumers can opt into const enum inlining and regular (non-const)
enum inlining. Previously both were hardcoded to `false` in the
`From<TypeScriptOptions>` conversion, making them unreachable from JS.

Dunqing e7e1aead4c feat(transformer/typescript): add optimize_enums option for regular enum inlining (#20539)
This is required in Rolldown to align with `esbuild`, which could inline a regular enum as long as all its enum members can be evaluated. See https://github.com/rolldown/rolldown/pull/8796
## Summary

Depends on #20508.

- Add `optimize_enums` option to `TypeScriptOptions` that treats regular enums with all-evaluable members the same as const enums: inlines member accesses and removes non-exported declarations
- Regular enums are only removed when no runtime value references remain (e.g., `typeof Foo`, passing as argument)
- Includes 14 conformance test fixtures covering basic, string values, binary expressions, cross-member/cross-enum references, merged enums, exported (kept), non-evaluable (kept), template literals, unary expressions, typeof/value-usage/passed-as-argument (kept), and re-exported (kept)

## Test plan

- [x] 14 new conformance test fixtures under `optimize-enums/`
- [x] `cargo run -p oxc_transform_conformance` passes
- [x] `cargo test -p oxc_transformer` passes
