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. #### What's Changed - Add playwright profiling package by [@&#8203;GuillaumeLagrange](https://redirect.github.com/GuillaumeLagrange) in [#&#8203;80](https://redirect.github.com/CodSpeedHQ/codspeed-node/pull/80) **Full Changelog**: <https://github.com/CodSpeedHQ/codspeed-node/compare/v5.4.0...v5.5.0> </details> <details> <summary>typescript-eslint/typescript-eslint (@&#8203;typescript-eslint/parser)</summary> ### [`v8.60.1`](https://redirect.github.com/typescript-eslint/typescript-eslint/blob/HEAD/packages/parser/CHANGELOG.md#8601-2026-06-01) [Compare Source](https://redirect.github.com/typescript-eslint/typescript-eslint/compare/v8.60.0...v8.60.1) This was a version bump only for parser to align it with other projects, there were no code changes.

camc314	7baed9c4b7	fix(transformer/private-method): clear inherited strict flags (#22508) ... Fixes private method transforms so scopes inherited from a transformed private method are converted back to sloppy mode when the surrounding scope is sloppy. Previously we only cleared `StrictMode` on the private method function scope itself. That left child scopes, such as async/generator wrapper scopes, marked as strict even though the transformed output is no longer inside a class method. This caused semantic rebuild mismatches across Babel and Test262 coverage. Nested classes are still left strict, since class bodies are always strict mode.	2026-05-25 09:39:48 +00:00
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 AI assistance was used in writing this patch and tests; the contributor has reviewed and tested locally. --------- Co-authored-by: Dunqing <dengqing0821@gmail.com>	2026-05-25 13:42:41 +08:00
Kyle Cannon	69a6ba6353	fix(transformer/legacy-decorator): emit Array for ReadonlyArray<T> in decorator metadata (#22265) ... ## Summary `ReadonlyArray<T>` is a TypeScript-only utility type with no runtime value. The legacy decorator metadata emit currently wraps it in the runtime guard `typeof (_ref = typeof X !== "undefined" && X) === "function" ? _ref : Object`, which always falls through to `Object` because there is no runtime `ReadonlyArray` binding. tsc resolves this through the checker and emits `Array`; OXC's existing handling of the short form `readonly T[]` already emits `Array`, so the generic form is the only divergent shape. ## The bug ```ts class Entity { @D() shortForm!: readonly string[]; // tsc: Array, OXC: Array (already correct) @D() genericForm!: ReadonlyArray<string>; // tsc: Array, OXC: Object (bug) @D() nestedReadonly!: ReadonlyArray<ReadonlyArray<number>>; // same } ``` The two surface forms describe the same type but produce different runtime metadata. Downstream consumers (TypeORM `@Column` array inference, NestJS Swagger schema, AutoMapper field detection) rely on the `Array` constructor; `Object` causes silent degradation. ## Fix In `serialize_type_reference_node`, recognize `ReadonlyArray` by name when the symbol is unresolved or type-only. Emit `global_array(ctx)` directly, bypassing the wrapper. A user-shadowed `class ReadonlyArray {}` would have a value symbol and falls through to the normal class-handling path, so the shadow case is preserved. ```rust if ident.name == "ReadonlyArray" && symbol_id.is_none_or(|sid| ctx.scoping().symbol_flags(sid).is_type()) { return Self::global_array(ctx); } ``` ## Scope Only `ReadonlyArray` is handled in this PR. `ReadonlyMap`, `ReadonlySet`, `WeakMap`, `WeakSet`, and `Readonly<Array<T>>` peel are left for a follow-up because tsc's spec emit for those is less unambiguous and warrants case-by-case verification. The same predicate-style approach extends naturally if reviewers want them folded in. ## Test plan - [x] 4 unit tests in `decorator_metadata_readonly_array.rs`: bare ReadonlyArray, nested ReadonlyArray, regression on `readonly T[]` short form, and a user-shadowed `class ReadonlyArray {}` regression - [x] New conformance fixture `oxc/metadata/readonly-array/` - [x] `cargo test -p oxc_transformer` passes (31 unit + 9 integration) - [x] `cargo run -p oxc_transform_conformance` shows 229 OXC fixtures still passing, +1 new fixture (`readonly-array`); 0 regressions - [x] `cargo fmt -p oxc_transformer` and `cargo clippy -p oxc_transformer --tests --no-deps` clean AI assistance was used in writing this patch and tests; the contributor has reviewed and tested locally. --------- Co-authored-by: Dunqing <dengqing0821@gmail.com>	2026-05-21 18:19:35 +08:00
Dunqing	e421ef0f84	fix(transformer/legacy-decorator): return runtime binding for design:type (#22640) ... Closes #22227. Closes #22228. ## Summary - Switch `design:type` / `design:paramtypes` / `design:returntype` emit from `typeof X === "function" ? X : Object` to `typeof X === "undefined" ? Object : X`, matching SWC and Babel. Cross-file imported enums and namespace-imported enums (`NS.E`) now return the actual enum object instead of silently degrading to `Object` — consumers like type-graphql, typeorm, NestJS Swagger, AutoMapper, and class-validator can introspect via `Object.values()`. - Cases where the runtime binding is genuinely missing still fall back to `Object` (stale ambient declarations, erased type imports, unresolved references), so existing behavior is preserved everywhere else. - See #14740 for the design rationale: matching SWC/Babel rather than tsc's primitive-type emit (which requires cross-file type information OXC doesn't have). - Conformance: 5 existing fixtures updated for the new emit shape, 6 new fixtures cover the bug paths and predicate boundaries; no `Output mismatch` regressions. ## Example Input: ```ts import { StringEnum } from './enums'; class Source { @dec value!: StringEnum; } ``` Before: ```js // design:type === Object — StringEnum is an enum object, typeof !== "function" babelHelpers.decorateMetadata("design:type", typeof (_ref = typeof StringEnum !== "undefined" && StringEnum) === "function" ? _ref : Object) ``` After: ```js // design:type === StringEnum (the enum object — introspectable via Object.values) babelHelpers.decorateMetadata("design:type", typeof StringEnum === "undefined" ? Object : StringEnum) ``` ## Note on the SWC enum-metadata debate [swc-project/swc#11033](https://github.com/swc-project/swc/issues/11033) argues SWC's emit is wrong for cross-file enums — the runtime returns the enum object (an `{...}`) rather than `Number` / `String` / `Object` as tsc would. This PR adopts the same emit shape SWC and Babel use, so it has the same property: cross-file enum metadata is the enum binding itself, not a primitive constructor. OXC chose this side of the debate deliberately in #14740 — returning the enum object is what type-graphql, typeorm, NestJS Swagger, AutoMapper, and class-validator depend on to introspect enum members. Matching tsc's primitive emit would require cross-file type information OXC doesn't have, and would unblock no real consumer. If TypeScript publishes a position on what non-type-checker transformers should emit, this can be revisited. AI disclosure: drafted with Claude Code, reviewed manually.	2026-05-21 09:50:07 +00:00

Dunqing	e6090e7ccc	fix(transformer): keep enum IIFE when a non-inlinable value reference remains (#22501) ... Refs vitejs/vite#22452 (comment). The optimize pass dropped the enum declaration whenever the members were all evaluable — regardless of whether some non-inlinable value reference still named the enum at runtime. The result referenced a binding that no longer existed: ```ts const enum Phase { one = 'one' } export default Phase; // -> export default Phase; // ReferenceError at runtime enum Direction { Up } Direction.Up.toString(); // -> Direction.Up.toString(); // ReferenceError at runtime ``` ## Fix Decide based on the remaining resolved references: drop only when none of them is a value reference (`Read`/`Write`). Type references (`as E`, `: E`) are kept here and stripped later by `annotations.rs`, so they don't block removal. `typeof E` in JS expression position is `Read` and correctly keeps the IIFE; `typeof E` in TS type position is `ValueAsType` (not in `Value`) and doesn't. Unifies the rule for regular and const enums — the previous asymmetry (const always dropped, regular dropped only when no refs at all) had no principled basis. ## Compatibility Diverges from Babel on two `optimize-const-enums/*` fixtures where the input has a bare value reference to the enum that we can't inline. Three engines disagree on what to do: | Engine | Inline `E.X` member accesses | Preserve `E` binding (IIFE) | Result for `E.unknown` / bare `E` | |---|---|---|---| | Babel `transform-typescript` (optimize-const-enums) | yes | **no** | runtime ReferenceError / TypeError | | tsc `--isolatedModules` | no | yes | `undefined` / resolves | | oxc after this PR | yes | yes | `undefined` / resolves | We now hybridize: inline what's inlinable (Babel) **and** keep the binding (tsc). Local overrides under `tasks/transform_conformance/overrides/` record the new expected output for the two affected Babel fixtures. ### `optimize-const-enums/local` Input: ```ts const enum A { x, y } A.x; A["y"]; A.z; A; ``` Babel (and oxc before this PR): ```js 0; 1; A.z; A; ``` `A.z` is `TypeError: cannot read properties of undefined`; `A;` is `ReferenceError`. tsc (`--isolatedModules`): ```js var A; (function (A) { A[A["x"] = 0] = "x"; A[A["y"] = 1] = "y"; })(A || (A = {})); A.x; A["y"]; A.z; A; ``` Keeps the IIFE binding, no member-access inlining. `A.z` evaluates to `undefined`; `A;` is a no-op. oxc after this PR (`overrides/.../optimize-const-enums/local/output.mjs`): ```js var A = /* @__PURE__ */ function(A) { A[A["x"] = 0] = "x"; A[A["y"] = 1] = "y"; return A; }(A || {}); 0; 1; A.z; A; ``` Hybrid: inlines `A.x` / `A["y"]` like Babel, **and** keeps the IIFE binding like tsc — so `A.z` evaluates to `undefined` (not crash) and `A;` resolves. ### `optimize-const-enums/merged` Input: ```ts const enum A { x, y } const enum A { z } A.x; A["y"]; A.z; A.w; A; ``` Babel (and oxc before this PR): ```js 0; 1; 0; A.w; A; ``` `A.w` is `TypeError: cannot read properties of undefined`; `A;` is `ReferenceError`. tsc (`--isolatedModules`): ```js var A; (function (A) { A[A["x"] = 0] = "x"; A[A["y"] = 1] = "y"; })(A || (A = {})); (function (A) { A[A["z"] = 0] = "z"; })(A || (A = {})); A.x; A["y"]; A.z; A.w; A; ``` Both IIFEs emitted, no inlining. `A.w` is `undefined`; `A;` resolves. oxc after this PR (`overrides/.../optimize-const-enums/merged/output.mjs`): ```js var A = /* @__PURE__ */ function(A) { A[A["x"] = 0] = "x"; A[A["y"] = 1] = "y"; return A; }(A || {}); A = /* @__PURE__ */ function(A) { A[A["z"] = 0] = "z"; return A; }(A || {}); 0; 1; 0; A.w; A; ``` Hybrid: both enum bodies lower (the second reuses the first's binding via `A = (function(A) { … })(A || {})` — assignment, not `var`) **and** members are inlined like Babel. `A.w` evaluates to `undefined`; `A;` resolves. ## Verification New fixtures cover the bug shapes: - `babel-plugin-transform-typescript/const-enum-value-ref-kept/` — `export default Phase` - `babel-plugin-transform-typescript/const-enum-mixed-refs/` — member access + bare ref combined Existing `optimize-enums/type-cast` updated to drop the IIFE for the all-type-refs case (the regular-enum side of the unified rule).	2026-05-18 02:19:11 +00:00
Dunqing	931b7d6b97	fix(transformer): inline const enum members through type-cast wrappers (#22500) ... Closes #22444. `Phase.idle as Phase`, `Phase.idle satisfies Phase`, `Phase.idle!`, and `<Phase>Phase.idle` failed to inline under `optimizeConstEnums`. The const enum declaration was stripped while the member access was left as `Phase.idle`, producing a runtime `ReferenceError`. ## Cause The enum inliner's `enter_expression` matched only bare `StaticMemberExpression`/`ComputedMemberExpression`. `annotations.rs` strips TS-only wrappers in its own `enter_expression`, but `walk_expression` only calls `enter_expression` once per node — after the strip the inner `Phase.idle` was never revisited. ## Fix Peek through the wrappers via `Expression::get_inner_expression_mut()` (it already handles `TSAsExpression`, `TSSatisfiesExpression`, `TSNonNullExpression`, `TSTypeAssertion`, `TSInstantiationExpression`, `ParenthesizedExpression`). The outer `*expr = …` replacement then drops the wrapper along with the inlined value. ## Example ```ts const enum Phase { idle, active } class Foo { #foo = Phase.idle as Phase; } ``` Before: ```js class Foo { #foo = Phase.idle; // dangling reference } ``` After: ```js class Foo { #foo = 0; } ``` ## Verification New fixtures cover all wrapper shapes for const + regular enums: - `babel-plugin-transform-typescript/const-enum-type-cast/` - `babel-plugin-transform-typescript/optimize-enums/type-cast/`	2026-05-18 02:19:10 +00:00
camc314	c73c159e16	fix(transformer/async-to-generator): reparent parameter initializer scopes (#22507) ... Fixes a semantic mismatch in `async_to_generator` for async methods with parameter default initializers. Before this change, the transform reused the original method scope as the inner generator scope and moved parameter bindings to the wrapper scope. Scopes created inside parameter defaults were left parented under the generator, even though the transformed AST places those defaults with the wrapper parameters. For example: ```js class C { async method(value = function fallback() {}) {} } ``` Conceptually this became: ```js class C { method(value = function fallback() {}) { // `value` belongs to this wrapper scope. return asyncToGenerator(function* () { // Before: the scope for `fallback` was still parented here, // because this generator reused the original async method scope. })(); } } ``` A fresh semantic rebuild from the transformed AST sees it differently: ```js class C { method(value = function fallback() { // After rebuild: `fallback` is created from the parameter default, // so its direct parent is the wrapper method scope. }) { return asyncToGenerator(function* () { // The generator should only own body scopes. })(); } } ``` This updates `BindingMover` so that when parameter bindings move to the wrapper, direct scopes created inside parameter-side expressions are reparented there too. It still stops at function/class scope boundaries, so nested body scopes are not traversed or moved.	2026-05-17 19:36:14 +00:00

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: -

camc314	ecfd3ca7c5	fix(transformer/async-to-generator): move only parameter bindings (#22503) ... Previously, given: ```js class C { async method(x = function y() {}) {} } ``` The async-to-generator transform generates: ```js class C { method(x = function y() {}) { return babelHelpers.asyncToGenerator(function* () {})(); } } ``` The method parameter stays on the outer wrapper method, while only the original body moves into the inner generator function. Before this change, `BindingMover` walked the full parameter AST while moving those parameter bindings. That meant it also visited default initializer expressions, so bindings created inside the initializer, like `y` above, could be moved out of their own function/class scope and into the wrapper method scope. After transform, rebuilt semantics would disagree with the transformed scope tree because the parameter binding was correct, but nested initializer bindings had the wrong owning scope. This PR makes `BindingMover` only visit the binding positions for formal parameters, rest parameters, and the left side of assignment patterns. It skips initializer expressions so nested function/class bindings stay in the scopes created for those expressions.	2026-05-17 17:22:46 +00:00
camc314	3ce3431717	fix(transformer/explicit-resource-managment): preserve shadowed for-head block (#22451) ... Given: ``` for (using x of y) { const x = z; } ``` Previously we would produce ``` var _usingCtx2 = require("@oxc-project/runtime/helpers/usingCtx"); for (const _x of y) try { var _usingCtx = _usingCtx2(); const x = _usingCtx.u(_x); const x = z; } catch (_) { _usingCtx.e = _; } finally { _usingCtx.d(); } ``` Now we produce ``` var _usingCtx2 = require("@oxc-project/runtime/helpers/usingCtx"); for (const _x of y) try { var _usingCtx = _usingCtx2(); const x = _usingCtx.u(_x); { const x = z; } } catch (_) { _usingCtx.e = _; } finally { _usingCtx.d(); } ``` Which avoids a syntax error - cannot create a duplicate var named `x`.	2026-05-16 11:10:11 +00:00

camc314	4e880de872	fix(transformer/object-rest-spread): declare temp vars for computed keys (#22284) ... Given some code like ```js const { [({ ...rest }) => { let { ...b } = {}; }]: a, [({ ...d } = {})]: c, } = {}; export {}; // necessary so we are in strict mode ``` It would previously be transformed to: ```js const { [(_ref) => { let rest = _extends({}, (_objectDestructuringEmpty(_ref), _ref)); let _ref2 = {}, b = _extends({}, (_objectDestructuringEmpty(_ref2), _ref2)); }]: a, [(_ref3 = {}, {} = _ref3, d = _extends({}, (_objectDestructuringEmpty(_ref3), _ref3)), _ref3)]: c } = {}; export {}; ``` This is a problem because there was no declaration to `_ref3` This causes runtime errors. After this PR, we now emit: This new code includes `var _ref3`, fixing the unresolved reference issue. ```js var _ref3; const { [_ref => { let rest = babelHelpers.extends({}, (babelHelpers.objectDestructuringEmpty(_ref), _ref)); let _ref2 = {}, b = babelHelpers.extends({}, (babelHelpers.objectDestructuringEmpty(_ref2), _ref2)); }]: a, [(_ref3 = {}, {} = _ref3, d = babelHelpers.extends({}, (babelHelpers.objectDestructuringEmpty(_ref3), _ref3)), _ref3)]: c } = {}; ``` This aligns with Babel. ---- This has been fixed by walking up to find the containing statement, and inserting the var declaration before it. Previously, the `var` declaration would only be inserted if we were inside `ExpressionStatementExpression` which was not guaranteed.	2026-05-11 09:14:25 +00:00
Dunqing	5da9fda0d8	fix(transformer/explicit-resource-management): preserve class names (#22306) ... Stacked on #22305. ## Why `class C { static getSelf() { return C } }` lowered by the explicit resource management transform was emitting `var C = class {}` (anonymous), so when the outer `C` is reassigned (`C = 123`), `getSelf()` returns the reassigned value instead of the original class — the exact behaviour the named class expression's inner binding is supposed to protect against. Babel emits `var C = class C {}` for the same input. ## Fix 1. **Emit `var C = class C {}`** for both `class C {}` and `export default class C {}`. Adds a `preserve_class_expression_name` helper that mirrors the swap in `decorator::legacy::transform_class_declaration_with_class_decorators` — generate a fresh `Class`-flagged symbol in the class scope for the inner class id, swap `class_decl.id.symbol_id` (via `Cell::replace`) to the new symbol, and repurpose the original symbol as the outer `var` (flags → `FunctionScopedVariable`). Returns the outer `BoundIdentifier` and the original span so the caller can emit the outer declarator with the correct span. 2. **Carry the original span through both sides of the swap.** The inner symbol is created with the original `id.span` (via `Scoping::create_symbol(span, ...)` + `add_binding`); the outer var's `BindingIdentifier` is emitted with the same span (via `BoundIdentifier::create_spanned_binding_pattern`, added in #22305). This eliminates the `Symbol span mismatch` diffs in: - `transform-top-level/hoisting/input.mjs` - `transform-top-level/hoisting-default-class/input.mjs` - `export-class-name/input.js` ## Comparison with Babel Babel reuses the *original `id` node* for the outer `var` and clones it for the inner class. This PR does the inverse — reuses the original *symbol id* for the outer `var` and generates a new symbol for the inner class. Given oxc's symbol-aware model, the inversion avoids rewiring every outer-scope reference (`const K = C`, `C = 123`, …): they already point at the original symbol. ## Remaining follow-up `export-class-name/input.js` still has `Symbol reference IDs mismatch` for `C` — references inside the class body (`return C`) still resolve to the outer symbol in the transformer's bookkeeping. A fresh semantic rebuild over the printed AST correctly resolves them to the inner class symbol, so tools that re-run semantic (rolldown / oxc_minifier on a fresh build) are fine. Tools that trust the transformer's symbol table directly (in-place minification / mangler) will see the stale binding. Rewiring those references is a separate follow-up (`Reference.symbol_id` update + `delete_resolved_reference` / `add_resolved_reference`). ## Conformance impact - Babel suite: **692 → 694 passing** (+2) - `transform-top-level/hoisting/input.mjs` ✓ - `transform-top-level/hoisting-default-class/input.mjs` ✓ - `export-class-name/input.js`: 4 span mismatches eliminated; reference-rewiring follow-up remains. ## Test plan - [x] `cargo run -p oxc_transform_conformance` - [x] `cargo run -p oxc_transform_conformance -- --exec` - [x] `cargo test -p oxc_transformer`	2026-05-11 08:34:24 +00:00

Dunqing	dd88726b8c	fix(transformer/legacy-decorator): preserve accessor type annotation for emitDecoratorMetadata (#21966) ... Fixes bug 7 of https://github.com/oxc-project/oxc/issues/21922. ## The bug `@dec accessor x: T` always emitted `design:type = Object` regardless of `T`: ```ts class Entity { @dec accessor name: string = ""; // tsc: design:type = String @dec accessor count: number = 0; // tsc: design:type = Number } ``` `Reflect.getMetadata("design:type", entity, "name")` returned `Object` instead of `String`. Frameworks reading `design:type` (NestJS Swagger, class-validator, TypeORM column metadata) silently degraded for every typed accessor field. ## Cause `lower_accessor_properties` (in `enter_class`) rewrites ```ts @dec accessor x: T = init; ``` into three members — a private storage field, a synthesized getter, and a synthesized setter — and transfers the decorators to the getter so the existing decorator pipeline picks them up. But it dropped the type annotation: the synth getter was constructed with `return_type: NONE`. The metadata pass runs later and takes the getter branch: ```rust if method.kind.is_get() { (self.serialize_type_annotation(method.value.return_type.as_ref(), ctx), None) } ``` `return_type` is `None` because lowering discarded it, so `serialize_type_annotation` correctly fell through to `Object` for what it sees as an untyped getter. The metadata pass's `enter_accessor_property` dispatch exists, but it never fires because the `AccessorProperty` no longer exists by the time traversal reaches the class body. ## Fix Stop dropping the type annotation. In `lower_accessor_properties`: ```rust let decorators = std::mem::replace(&mut accessor.decorators, ctx.ast.vec()); let type_annotation = accessor.type_annotation.take(); ``` Thread `type_annotation` through `create_accessor_method` to the getter (setter passes `None`). To avoid a post-construction patch on the synthesized `MethodDefinition`, `create_class_method` now takes a `return_type: Option<ArenaBox<TSTypeAnnotation>>` parameter and threads it directly into the function's return-type slot. The other caller (`create_class_constructor_with_params`) passes `None`. The lowered AST is now self-consistent — the synth getter for `accessor x: T` reads as a getter that returns `T`, which is what it semantically is, and the existing getter-metadata path serializes it correctly. ## Out of scope (architectural limit) `type Uuid = string; @dec accessor x: Uuid` still emits `Object`, same as for non-accessor properties. Resolving type-alias references to their primitive constituent requires a name-based alias-resolution pass (the same one that `tsc`'s checker provides via `getTypeReferenceSerializationKind`). That's bug 1 of #21922 and a separate change from this fix; flagged here so reviewers don't mistake it for an omission. ## Test plan - [x] Conformance fixture `oxc/metadata/accessor` covers primitives, untyped (correctly stays `Object`), `string[]` → `Array`, `static accessor`, and computed-key (`@dec accessor ["computed"]: number`) - [x] `cargo test -p oxc_transformer` — 31 + 5 passed - [x] `cargo run -p oxc_transform_conformance -- --filter legacy-decorators` — 73 pass / 23 fail (baseline 72/24, +1 new fixture, **0 regressions**) - [x] `cargo run -p oxc_transform_conformance -- --exec` — accessor exec test verifies `Reflect.getMetadata` returns the correct constructor at runtime - [x] `cargo fmt -p oxc_transformer`	2026-05-07 14:17:45 +00:00
Dunqing	0c7c01c63b	fix(transformer/typescript): inline optional-chain enum member access (#21834) ... ## Summary Closes #21813. Closes #21828. `c_num?.x` and `c_num?.['x']` were not handled by the enum-inlining pass in `enter_expression`, which only matched `Expression::StaticMemberExpression` and `Expression::ComputedMemberExpression`. When the es2020 optional-chain plugin lowered the chain first, the member access became: ```js c_num === null || c_num === void 0 ? void 0 : c_num.x ``` Then the inline pass saw the inner `c_num.x` and replaced it with the constant + deleted *that one* reference — but the two references in the test condition stayed live. With `optimizeConstEnums: true`, the const-enum declaration is then unconditionally removed, leaving dangling references to a binding that no longer exists. The same shape underlies the rolldown report ([rolldown/rolldown#9181](https://github.com/rolldown/rolldown/issues/9181)) where rolldown's cross-module enum inlining drops the import that `c_num` was bound to. ## Fix Match `Expression::ChainExpression` whose top element is an optional `StaticMemberExpression` or `ComputedMemberExpression` on an enum identifier, and inline the entire chain to the constant **before** es2020 sees it. Reuses the existing `try_inline_enum_member` / `try_inline_computed_enum_member` helpers — they don't care about the `optional` flag. ## Fixtures - `optimize-enums/optional-chain-issue-21813/` — the bug case + an `exec.ts` that runs the transformed output to verify runtime semantics - `optimize-enums/optional-chain-value-kept/` — IIFE preserved when a bare `Foo` ref also exists - `optimize-enums/optional-chain-deeper-access/` — `Foo?.x.toString()` / `Bar?.['y']?.toString()` exercise nested chains where the inner inline still fires via the existing arms - `const-enum-optional-chain/` — const-enum path with `optimizeConstEnums: true` ## Known limitation Deeper chains under es2020 lowering — `c_num?.x.y` or `c_num?.x()` where the optional access is below the chain element — still produce dangling refs because the chain element is non-optional or a `CallExpression` and this fix's match arm doesn't trigger. Without es2020 lowering they work (the inner `?.x` gets visited as a regular `Expression::StaticMemberExpression`), so the conformance fixtures pass. A more general fix would walk the chain to find the leftmost optional-on-enum access; out of scope for this PR. ## Test plan - [x] `cargo run -p oxc_transform_conformance -- --filter optimize-enums/optional-chain` — all three pass - [x] `cargo run -p oxc_transform_conformance -- --filter const-enum-optional-chain` — passes - [x] `cargo run -p oxc_transform_conformance -- --exec --filter optimize-enums/optional-chain-issue-21813` — runtime check passes - [x] `cargo test -p oxc_transformer` — green - [x] `cargo clippy -p oxc_transformer -- -D warnings` — clean - [x] CI Conformance — green (snapshots updated for `oxc.snap.md` + `oxc_exec.snap.md`)	2026-05-07 09:04:41 +00:00

Ido Rosenthal	9593ec8b6b	feat(transformer/jsx): add jsxDEV source metadata for fragments (#21932) ... Before this change, fragment transforms omitted source location metadata: ```js _jsxDEV(_Fragment, { children: "test" }, void 0, false); ``` After this change, fragments receive the same trailing development metadata as other JSX `jsxDEV` calls: ```js _jsxDEV(_Fragment, { children: "test" }, void 0, false, { fileName: _jsxFileName, lineNumber: 2, columnNumber: 10 }, this); ``` ## Motivation This came from [#21042](https://github.com/oxc-project/oxc/issues/21042). TypeScript's `react: reactJSXDev` transform also emits fragment source locations and `this` for same case: https://www.typescriptlang.org/play/?jsx=5#code/DwPgUABBwCYJYDcTAPTyZa7lseV4QA ## Changes - allow fragment `jsxDEV` calls to receive source metadata in the JSX transformer - update the local transform conformance fixture for `fragment-static-children` --------- Co-authored-by: Dunqing <dengqing0821@gmail.com>	2026-04-30 14:39:49 +08:00
Dunqing	e3399ec3a6	fix(transformer/class-properties): preserve RHS in logical-assignment to static private field (#21950) ... fixes #21874 `transform_static_assignment_expression` took `assign_expr.right` once at the top of the function (correct for the `=` branch), then took it a second time inside the `else` branch that handles compound operators. The second `take_in` returned a `NullLiteral` dummy, so `??=` / `&&=` / `||=` (and the binary ops) on a static private field where the receiver isn't a direct class reference — e.g. `this.#shared ??= 1` inside a static method — emitted `null` in place of the RHS: ```js // before class Singleton { static #shared; static shared() { this.#shared ??= 1; return this.#shared; } } // transformer output (broken): _assertClassBrand(Singleton, this, _shared)._ ?? (_shared._ = _assertClassBrand(Singleton, this, null)); // ^^^^ should be 1 ``` Removes the redundant inner `let class_ident = …; let value = assign_expr.right.take_in(…);` shadowing so the compound-operator branches use the already-captured outer `value` (the real RHS) when building the `_assertClassBrand(Class, object, value)` call. Output now matches Babel. Adds a `private-static-logical-assignment` conformance fixture covering `??=`, `&&=`, and `||=`, plus an `exec.js` to verify runtime behavior.	2026-04-30 00:39:26 +00:00
Dunqing	c59c1990bc	fix(transformer/typescript): emit class fields for parameter properties (#21831) ... ## Summary Fixes a long-standing inconsistency in the TypeScript transformer's handling of constructor parameter properties under the documented default (`useDefineForClassFields: true` per [`compiler_assumptions.rs:137-139`](https://github.com/oxc-project/oxc/blob/main/crates/oxc_transformer/src/compiler_assumptions.rs#L137-L139)). The transformer already emitted TS-true-aligned output for **declared** fields (kept `boom: number;` as `boom;`) but silently dropped the field declaration for **parameter properties**, so downstream tools that re-analyze the transformed AST saw the property only as a `this.*` write, not as a declared class field. ```ts // input class Foo { boom: number; // declared field constructor(public foo) {} // parameter property } ``` ```js // before — inconsistent class Foo { boom; // ✅ kept (TS-true) constructor(foo) { // ❌ missing `foo;` (TS-false-style for params only) this.foo = foo; } } // after — consistent class Foo { foo; // ✅ now matches `boom;` boom; constructor(foo) { this.foo = foo; } } ``` This is **not a policy change** — the documented default has always been `useDefineForClassFields: true` (set both `set_public_class_fields` and `remove_class_fields_without_initializer` to `true` to opt into `false` semantics). The fix just closes the missing case for parameter properties. ## Implementation - Add `add_parameter_property_fields` to the `enter_class` path that runs when `set_public_class_fields` is `false`, mirroring the existing branch that calls `transform_class_fields` when it is `true`. - Skip parameter properties whose name matches an existing instance field on the same class (matches tsc's dedup). Static, private, and `declare`-only fields are different bindings, so they don't suppress the new field. - Early-bail before allocating the dedup set when the class has no parameter properties — keeps the transformer-allocations snapshot at baseline. No new option is added; the existing `set_public_class_fields` assumption already maps cleanly to `useDefineForClassFields` (the playground's `useDefineForClassFields: true` already toggles `set_public_class_fields = false`).

Dunqing	91e5bde420	fix(transformer/typescript): preserve computed-key static block when class has an empty constructor (#21562) ... ## Summary When a TypeScript class used a computed-key static property together with a constructor that has no parameter-property assignments, the early return in `transform_class_fields` dropped the `computed_key_assignment_static_block` that initializes the temp var, leaving it declared but never assigned. ```ts export class SampleClass { static [Symbol.toPrimitive] = "test" constructor() {} } ``` previously emitted: ```js let _Symbol$toPrimitive; export class SampleClass { static { this[_Symbol$toPrimitive] = "test"; } constructor() {} } ``` Now emits (matching TypeScript's own output under `useDefineForClassFields: false`): ```js let _Symbol$toPrimitive; export class SampleClass { static { _Symbol$toPrimitive = Symbol.toPrimitive; } static { this[_Symbol$toPrimitive] = "test"; } constructor() {} } ``` ## Test plan - Added fixtures `computed-static-property-with-constructor` (exact repro) and `computed-static-property-with-constructor-super` (super() + multiple computed keys) under `babel-plugin-transform-typescript`. - Verified output against `tsc` 5.7 with `useDefineForClassFields: false`. Closes rolldown/rolldown#9121	2026-04-20 15:58:31 +08:00
Dunqing	56af2f4fe0	fix(transformer/async-to-generator): correct scope of inferred named FE in async-to-generator (#21458) ... When the async-to-generator transform wraps an async arrow / anonymous async function expression whose name is inferred from its parent (e.g. `const foo = async () => {}`, `{ foo: async () => {} }`), it emits a named function expression as the caller: ```js const foo = function () { var _ref = asyncToGenerator(function* () { /* body */ }); return function foo() { return _ref.apply(this, arguments); }; }(); ``` Per the JS spec, the inferred name `foo` binds only inside the named FE itself — not in the enclosing wrapper IIFE scope. But the previous code had two bugs that together caused oxc to emit an AST that a fresh semantic analysis (e.g. Rolldown's minifier in Vite, or oxc's own minifier) would misread: 1. `create_function` set `FunctionType::FunctionDeclaration` whenever `id.is_some()`, even for callers using the result as a function expression. Any fresh semantic pass trusts `r#type` and treats the node as a declaration — which binds the name in the enclosing wrapper scope. 2. The inferred id's binding was registered in `wrapper_scope_id` rather than the function's own scope. Combined, downstream minifiers resolve a body reference like `typeNext()` inside `const typeNext = async () => { typeNext(); }` to the inner caller instead of the outer `const typeNext`. The outer const then looks unused, gets inlined away, and the body reference fails at runtime with `ReferenceError: typeNext is not defined`. ## Fix Pass `FunctionType` explicitly (via new `create_function_expression` and `create_function_declaration` helpers), and place the inferred id's binding in the caller function's own scope. ## Runtime verification Ran input → oxc transform → oxc compress (same pipeline Rolldown/Vite uses): **Pre-fix** output (matches the exact bug in the Vite issue — outer const inlined away): ```js (function() { var _ref = _asyncToGenerator(function* () { ..., typeNext(); }); return function typeNext() { return _ref.apply(this, arguments); }; })()(); ``` Runtime: `ReferenceError: typeNext is not defined` ✗ **Post-fix** output (outer const preserved; minifier correctly drops the now-unused inner FE name): ```js const typeNext = function() { var _ref = _asyncToGenerator(function* () { ..., typeNext(); }); return function() { return _ref.apply(this, arguments); }; }(); typeNext(); ``` Runtime: works correctly ✓ Closes #21125 Closes #21445	2026-04-15 14:06:08 +00:00

Dunqing	4fb73a7af9	fix(transformer/typescript): preserve execution order for accessor with useDefineForClassFields: false (#21369) ... ## Summary When `useDefineForClassFields: false` (`setPublicClassFields` assumption), the TypeScript transform moves public/TS-private field initializers into the constructor. However, private field initializers (including `accessor` backing fields from the legacy decorator transform) were left as class field declarations, causing them to execute **before** the constructor body. This broke execution order when the initializer depended on other fields that were already moved to the constructor. **Input:** ```ts class Hello { private input = { foo }; accessor util = this.input.foo(); } ``` **Before (broken):** `this.input.foo()` runs before `this.input = { foo }` ```js class Hello { constructor() { this.input = { foo }; } #_util_accessor_storage = this.input.foo(); // ← runs BEFORE constructor } ``` **After (fixed):** all instance initializers in the constructor, in source order ```js class Hello { constructor() { this.input = { foo }; this.#_util_accessor_storage = this.input.foo(); } #_util_accessor_storage; } ``` ### Approach Matches TypeScript's [`WillHoistInitializersToConstructor`](https://github.com/microsoft/TypeScript/blob/7b8cb3bdf82f400642b73173f941335775d6f730/src/compiler/transformers/classFields.ts#L339) logic in [`shouldTransformAutoAccessorsInCurrentClass`](https://github.com/microsoft/TypeScript/blob/7b8cb3bdf82f400642b73173f941335775d6f730/src/compiler/transformers/classFields.ts#L1069-L1073): - Pre-scan the class body to check if any non-private instance field has an initializer that will be hoisted - When hoisting occurs, include **all** instance fields (including `#` private) in the hoisting to preserve execution order - When no public fields are being hoisted, private fields stay as class field declarations No changes needed to the decorator/legacy transform — the fix is entirely in `transform_class_fields`.

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	2026-04-13 08:49:23 +00:00

Amal Jossy	af1a586501	fix(transformer/class-properties): use correct property name when converting parameter properties (#21268) ... ## Summary Fixes #21116 where TypeScript constructor parameter properties emit the wrong property name when the parameter name clashes with a free variable referenced in a class field initializer. ## Problem When targeting pre-ES2022 (or with `transform-class-properties` enabled), the class properties plugin detects that a constructor parameter name shadows an outer variable referenced in a field initializer, and renames the parameter binding (e.g. `x` → `_x`) to preserve the initializer's semantics. `convert_constructor_params` (TypeScript plugin) ran after this rename and read `id.name` — which had already been mutated — to produce the `this.X = X` assignment. This caused: ```ts let x = 10; class Foo { field = x; constructor(public x: number) {} } ``` to incorrectly emit: ```js constructor(_x) { this._x = _x; // ❌ property name should be x ... } ``` ## Root Cause Both plugins share a single traversal pass with interleaved hooks. `enter_class_body` (class properties) fires before `enter_method_definition` (TypeScript), so by the time `convert_constructor_params` runs, `BindingIdentifier.name` has already been mutated by `ConstructorSymbolRenamer`. ## Fix Recover the property name from `id.span.source_text(source_text)` instead of `id.name`. Spans are set by the parser and never mutated by any transformer, so this always returns the original user-written identifier regardless of renames. ```ts constructor(_x) { this.x = _x; // ✅ ... } ``` ## AI Disclosure This fix was developed with Claude Code assistance.

Dunqing	eab13b39e3	fix(transformer/decorators): avoid accessor storage name collisions (#21106) ... ## Summary - Use raw property/identifier names instead of `get_var_name_from_node` (which strips leading underscores) when generating private backing field names for accessor properties - For non-computed keys, use `PropertyKey::name()` which preserves leading underscores - For computed keys, match on `Expression::Identifier` to get the raw name directly - No counters, maps, or helper functions needed — collisions are avoided at the source This prevents `accessor prop` and `accessor _prop` from producing the same `#_prop_accessor_storage` name, which caused a runtime `TypeError: Cannot initialize the same private elements twice on an object`. Closes #20946 Supersedes #21023 ## Test plan - [x] Added test fixture covering both non-computed (`prop`/`_prop`) and computed (`[prop]`/`[_prop]`) accessor name collisions - [x] All existing accessor tests pass unchanged - [x] `cargo test -p oxc_transformer` passes - [x] Full `cargo run -p oxc_transform_conformance` passes - [x] `cargo clippy` clean 🤖 Generated with [Claude Code](https://claude.com/claude-code)	2026-04-08 02:22:25 +00:00

Dunqing	33756270c8	fix(transformer): remove false positive duplicate __source/__self prop error (#20678) ... Fixes #20654 The JSX source and self plugins were erroneously reporting "Duplicate `__source` prop found" / "Duplicate `__self` prop found" warnings when a user wrote `<div __source={{}} />` or `<div __self={this} />`. This prevented valid code from being transformed. In Babel, the duplicate error only exists to warn users who have both the automatic runtime AND the deprecated standalone plugins enabled simultaneously ([source](https://github.com/babel/babel/blob/9137617716e200cb440948562789ae3744559fcb/packages/babel-plugin-transform-react-jsx/src/create-plugin.ts#L847-L853)). It's not relevant for oxc as a standalone transformer. Now the plugins silently skip adding `__source`/`__self` when the user has already provided one, matching the behavior of Babel's standalone plugins.	2026-03-24 10:47:59 +00:00
Dunqing	3931b98132	fix(transformer): ignore @jsxImportSource inside inline code spans in comments (#20674) ... ## Summary - Fix JSX pragma scanner incorrectly matching `@jsxImportSource` inside backtick code spans (e.g. `` `@jsxImportSource custom/source` ``) in doc comments - Add validation that `@` must be preceded by whitespace, `*`, or be at the start of the comment ## Problem The `memchr`-based `@` search found pragma directives anywhere in a comment, including inside inline code spans. This caused: 1. A `@jsxImportSource` inside a doc comment overriding the actual file-level pragma 2. The trailing backtick being included in the import specifier (`` custom/source` ``) This broke Vite 8 dev server when `.tsx` files had JSDoc comments mentioning `@jsxImportSource`. ## Design | Tool | `@` position check | |------|-------------------| | esbuild | None — matches `@jsx` anywhere in comment | | Babel | Full start-of-line regex (`^\s*(?:\*\s*)?@jsx`) | | **Oxc (this PR)** | Preceding byte must be whitespace, `*`, or start of comment | We intentionally sit between esbuild and Babel — checking only the immediately preceding byte is sufficient for the backtick case without being as strict as Babel's full start-of-line regex. Fixes #20669 ## Test plan - [x] Unit tests added for backtick-wrapped pragmas - [x] Conformance test fixture added (`issue-20669`) - [x] All existing transformer tests pass - [x] Clippy clean 🤖 Generated with [Claude Code](https://claude.com/claude-code)	2026-03-24 09:22:51 +00:00
