WASM - Bindings/adapters: TypeScript

Generate high-performance TypeScript type definitions and JavaScript glue code for WebAssembly components using the Component Model.

Jco (and the underlying wit-bindgen tooling) streamlines the integration of WASM modules into TypeScript environments by transpiling WIT (WebAssembly Interface Types) files into native ESM modules. This process eliminates manual buffer management: it automatically generates precise TypeScript interfaces for complex types like strings, records, and variants. By leveraging the Bytecode Alliance's tooling, developers get full IDE autocompletion and type safety for cross-language imports, ensuring that a WASM binary compiled from Rust or C++ behaves like a standard, type-safe npm package.
