@wyw-in-js/turbopack-loader

Turbopack-compatible loader for WyW-in-JS.

This package is designed to be used via Next.js turbopack.rules.

Eval resolver modes

eval.resolver: 'native' and the native step of eval.resolver: 'hybrid' use oxc-resolver with automatic tsconfig.json discovery.

When this loader is configured through @wyw-in-js/nextjs, string aliases from turbopack.resolveAlias or experimental.turbo.resolveAlias are forwarded into native resolver options. Direct turbopack.rules usage should mirror Turbopack-only aliases in oxcOptions.resolver.alias or use hybrid so the bundler fallback can resolve them.

Output strategy

When a file produces CSS, the loader:

• writes *.wyw-in-js.module.css next to the source file (only if content changed, atomically);
• injects import './<file>.wyw-in-js.module.css' into the transformed module;
• wraps selectors in :global(...) so Next's CSS Modules pipeline does not rename WyW-generated class names.
