It was previously exposed as a `reactCompiler` transform option (added in #22942, shipped in 0.135.0 / 0.136.0). **Why not feature-gate it instead?** Gating React Compiler in the binding can't produce a consistent `index.d.ts`: - Keep the option types unconditionally → the published `.d.ts` advertises a `reactCompiler` option that a default (feature-off) build silently ignores. - Gate the type surface too → CI's `build-test` (which would enable the feature) regenerates a `.d.ts` that no longer matches the checked-in lean one, breaking `git diff --exit-code`. Removing it from the binding sidesteps both. React Compiler stays available to the Rust `oxc_transformer` crate behind its own `react_compiler` feature — only the napi binding loses it. ## Changes - Drop the `reactCompiler` option and the `ReactCompilerOptions` / `ReactCompilerGating` / `ReactCompilerDynamicGating` types. - Remove the `oxc_react_compiler` dependency and stop enabling `oxc`'s `react_compiler` feature. - Delete `src/react_compiler.rs` and `test/reactCompiler.test.ts`. - Regenerate `index.d.ts` (drops the three interfaces + the field; `index.js` is unchanged — they were type-only). ## Breaking change `oxc-transform` no longer accepts the `reactCompiler` option. It shipped in 0.135.0 and 0.136.0. ## Verification - `cargo check` + `cargo clippy --all-targets`: clean. - `cargo shear`: no issues; `Cargo.lock` drops only the `oxc_transform_napi → oxc_react_compiler` edge. - No remaining `reactCompiler` / `ReactCompilerOptions` references anywhere else in the repo. - `pnpm build-test` + `pnpm test`: 53/53 pass (the React Compiler test is removed). 🤖 Generated with [Claude Code](https://claude.com/claude-code)	2026-06-18 17:20:55 +08:00

Boshen	c782419c3e	refactor(transformer): order transform options by evaluation order (#23241) ... Reorders the option struct fields in `oxc_transformer` and the napi transform binding to match the order their transforms are evaluated, and documents that order on each struct. Behavior-neutral; the only externally visible change is field order and docs in the generated `index.d.ts`. - **`TransformOptions`** (`oxc_transformer`): `react_compiler` (separate pass before the traversal) → `typescript` → `decorator` → `plugins` → `jsx` → `env`, with `helper_loader` last (not a transform). Previously `plugins` sat after `env` and `react_compiler` was last despite running first. - **`EnvOptions`**: was ascending `es2015`→`es2026`; now `module` (consumed by the TypeScript transform), then `es2026` down to `es2015`, then `regexp` last. - **`ES2020Options`**: `optional_chaining` moved next to `nullish_coalescing_operator`, matching their `enter_expression` order. - **napi `TransformOptions`**: follows the full compiler pipeline — `lang`/`sourceType` (parse) → `assumptions` → `reactCompiler` → `typescript` → `decorator` → `plugins` → `jsx` → `target` → `helpers` → `inject` → `define` → `sourcemap` (codegen). Two things this surfaced: `inject` runs **before** `define` (the struct listed them reversed), and `sourcemap` is a codegen option so it belongs at the end. `index.d.ts` regenerated. The canonical order is `TransformerImpl`'s field order in `lib.rs` (and `CompilerInterface::compile` for the napi pipeline stages); a note on `TransformerImpl` now reminds maintainers to keep `TransformOptions` in sync. Verified: `cargo check`/`clippy --all-features --all-targets` (CI profile), `cargo test -p oxc_transformer`, napi vitest 62/62, transform conformance with zero snapshot diffs. 🤖 Generated with [Claude Code](https://claude.com/claude-code)	2026-06-12 13:33:42 +00:00
Boshen	777f02ae10	refactor(diagnostics)!: return a Diagnostics type instead of Vec<OxcDiagnostic> (#23217) ... ## Summary Introduces `oxc_diagnostics::Diagnostics` — a `Vec<OxcDiagnostic>` newtype that knows the difference between errors and warnings — and makes it the standard diagnostics return value across oxc. - **New type**: `Diagnostics` with `has_errors()`, `has_warnings()`, `errors()`, `warnings()`, plus `Vec`-like ergonomics (Deref, `IntoIterator`, `Extend`, `From`/`Into<Vec>`) so most call sites are unchanged. - **Return types**: `ParserReturn`, `SemanticBuilderReturn`, `IsolatedDeclarationsReturn`, the React Compiler `TransformResult`/`LintResult`, and `TransformerReturn` now expose `diagnostics: Diagnostics` instead of `errors: Vec<OxcDiagnostic>` (the React Compiler's separate `errors`/`warnings` are merged into one severity-tagged list). - **Behaviour**: a React Compiler **error** now stops the transform (no output), while **warnings** flow through and the transform continues. `compile()` aborts codegen only when `diagnostics.has_errors()` — warnings alone no longer abort (previously any diagnostic did). ## Breaking change Consumers reading `*.errors` on these return values must read `*.diagnostics`. React Compiler consumers that read `.errors`/`.warnings` separately should use `diagnostics.has_errors()` / `diagnostics.errors()` / `diagnostics.warnings()`. Parser/semantic/isolated-declarations fatality is otherwise unchanged.

Boshen	ec266bb733	feat(transformer): run React Compiler as a feature-gated transform pass (#23201) ... ## Summary Exposes the React Compiler from `oxc_transformer` behind a Cargo feature so callers no longer need a separate `oxc_react_compiler::transform` + scoping-rebuild step before transforming. - **`oxc_transformer`**: new `react_compiler` Cargo feature (off by default) + `TransformOptions::react_compiler` field. When set, `Transformer::build_with_scoping` runs the React Compiler first (via a private `run_react_compiler` method), replacing the program and rebuilding scoping for the downstream transforms. - **Opt-in**: the feature is **not** enabled by `oxc_transformer`'s defaults, nor by `oxc`'s `transformer`/`full` features — enabling the transformer does not pull the heavy `oxc_react_compiler` dependency. It is a separate `react_compiler` feature on `oxc` (which implies `transformer`); the napi transform binding opts in explicitly. - **Dedupe**: removes the inline React-Compiler orchestration (and the `react_compiler_options()` hook) from `oxc`'s `CompilerInterface` and the napi transform binding; both now drive it through `TransformOptions::react_compiler`. - **Diagnostics**: the compiler's errors and warnings are merged into `TransformerReturn::errors` (each keeps its severity; downstream filters). `compile()` reports them but no longer aborts codegen — the transformer always leaves a valid program, matching the documented "code may still be available even if there are errors" behaviour. - **Links**: updates the React Compiler references to the merged upstream location (`react/react/tree/main/compiler`). ## Notes Transform/codegen output is unchanged when the feature is off (the field defaults to `None` everywhere). The diagnostics behaviour change (no codegen abort) is conformance-safe — the transform-conformance harness keys off reported diagnostics, not printed output. 🤖 Generated with [Claude Code](https://claude.com/claude-code)	2026-06-10 08:03:07 +00:00
Boshen	bb0ed44541	feat(transformer)!: disable styled-components transpileTemplateLiterals by default (#23171) ... ## Summary Closes #13398. The styled-components transform's `transpileTemplateLiterals` option rewrites tagged template literals into the array-call form: ```js // in styled.div`width: 100%;` // out — transpileTemplateLiterals: true styled.div(["width: 100%;"]) ``` This form is only more compact when template literals are *also* down-levelled to ES5 — which is why `babel-plugin-styled-components` enables it by default, to pre-empt Babel's verbose `_taggedTemplateLiteral` output. Oxc does not down-level template literals below ES6, so the array-call form is strictly *larger* than leaving the tagged template untouched. This PR flips the default to `false`, as agreed with @Dunqing in #13398. ## Changes - `StyledComponentsOptions::transpile_template_literals` now defaults to `false` (both the `serde` field default and the `Default` impl), with docs explaining why. - napi: `transpileTemplateLiterals` is documented `@default false` (`transformer.rs` + `index.d.ts`), and the styled-components napi test snapshot now reflects the non-transpiled default output. - Conformance fixtures that relied on the old default and whose reference output is transpiled now pin `transpileTemplateLiterals: true`, so they keep matching `babel-plugin-styled-components`' reference output. The conformance snapshot is unchanged — `plugin-styled-components` stays at 25/40. ## Breaking change `transpileTemplateLiterals` now defaults to `false`. Pass `transpileTemplateLiterals: true` to restore the previous behavior. 🤖 Generated with [Claude Code](https://claude.com/claude-code)	2026-06-10 03:26:40 +00:00

Closes https://github.com/oxc-project/oxc/issues/10048 Integrates the Rust port of the React Compiler ([facebook/react#36173](https://github.com/facebook/react/pull/36173)) into oxc. ## Notes (resolved) - Published crates can't reference Git URLs, so using this from Rolldown needs the React Compiler crates on crates.io. ✅ Published as a fork at https://crates.io/crates/forked_react_compiler; this PR depends on those `forked_react_compiler*` crates so people can get earlier access. - The React Compiler crates had no license field. ✅ The published fork carries `license = "MIT"` (per the React repo's MIT license), so Cargo Deny and Security Analysis pass. ## Benchmark **Wall-clock overhead vs plain transform** (release `transformSync`, same `jsx: automatic`, toggling only `reactCompiler`): | fixture | without | with | overhead | | --- | --- | --- | --- | | RadixUIAdoptionSection.jsx (2.5 KiB) | 0.03 ms | 1.81 ms | +1.8 ms | | excalidraw `App.tsx` (406 KiB) | 4.09 ms | 14.49 ms | +10.4 ms (3.5×) | So roughly a fixed ~1.8 ms floor per file plus a per-size cost — about **3.5× the transform time** on a large real-world component. ## Binary size Linking the React Compiler pulls the whole compiler pipeline (HIR, lowering, inference, SSA, optimization, reactive scopes, validation) plus the oxc⇄Babel AST conversion into the binding.

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, ...).

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

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!	2026-04-23 22:43:16 +01:00

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