dynwinrt Wiki

Call Windows Runtime (WinRT) APIs from JavaScript, TypeScript, or Python without writing a native extension.

dynwinrt reads Windows metadata at runtime, generates typed language wrappers, and dynamically invokes the underlying APIs through a shared Rust and libffi runtime.

This wiki is a curated entry point. Versioned documentation and implementation details remain in the main repository.
