Run the Rust port of the React Compiler (oxc-project/oxc#22942) at the pre-ecma-ast stage, gated by a new `transform.reactCompiler` option. - pin the oxc crates to the integration PR via [patch.crates-io], and add the oxc_react_compiler git dependency - add `react_compiler` to the bundler transform options; run it on the pristine AST in pre_process_ecma_ast before the oxc transformer, returning the scoping the rest of the pipeline uses - expose it as `reactCompiler?: boolean | ReactCompilerOptions` through the napi binding (reusing oxc_transform_napi's resolver) and the TS types - add a snapshot integration test (enabled vs disabled) Depends on oxc-project/oxc#22942; the patch pins a git rev until it lands.

[patch.crates-io], and add theoxc_react_compilergit dependency.react_compilerto the bundler transform options; run it on the pristine AST inpre_process_ecma_astbefore the oxc transformer, returning the scoping the rest of the pipeline uses (mirrors howoxc::Compilersequences it).reactCompiler?: boolean | ReactCompilerOptionsthrough the napi binding (reusingoxc_transform_napi's resolver) and the TS types.crates/rolldown/tests/rolldown/topics/react_compiler/{basic,disabled}— enabled emits thereact/compiler-runtimeimport +c(n)memo cache; disabled does not.Usage
Notes
[patch.crates-io]pins a git rev until that lands; swap to a released oxc version before merging._cimport alias is renamed by rolldown's scope-hoisting linker (toc/react_compiler_runtime.c), so the test asserts on thereact/compiler-runtimeimport + memo cache rather than the literal_c(token.--workspacecheck, clippy, fmt, tsc, and the Rust snapshot test all pass).🤖 Generated with Claude Code
