📝 Walkthrough

Walkthrough

The plugin-react package gains support for the React Compiler via a new exported ReactCompilerOptions type and an optional reactCompiler field added to the PluginReactOptions interface. In the plugin's setup function, the SWC transform configuration is refactored to construct a transformOptions object that always includes the react transform settings and conditionally includes reactCompiler when the option is provided, before passing the combined object to tools.swc.jsc.transform. Two new tests verify that both the boolean form (reactCompiler: true) and the object form (reactCompiler: { target: '18' }) are correctly reflected in the generated loader rules for .tsx files. The e2e test case is updated to demonstrate the plugin-based React Compiler configuration, and the Babel compiler dependency is removed from the workspace catalog.
