wasm-bindgen is a Rust library and CLI tool that generates high-level bindings between WebAssembly modules and JavaScript, allowing rich types like strings, objects, and classes to cross the JS/wasm boundary. It is a core part of the Rust and WebAssembly ecosystem, often used together with wasm-pack.

Use cases

• call Rust functions from JavaScript in the browser
• import JavaScript APIs like DOM or console into Rust
• generate TypeScript bindings for Rust wasm code
• pass strings and objects between wasm and JavaScript
• build web apps with Rust compiled to WebAssembly
• publish Rust wasm packages to npm

When to choose

• you are writing Rust that compiles to WebAssembly and needs JS interop
• you want rich type exchange (strings, closures, classes) between wasm and JS
• you want automatic TypeScript definitions for your Rust exports

When to avoid

• you compile to wasm from C/C++ or other non-Rust languages
• your wasm module has no JavaScript interaction
• you target server-side wasm runtimes without a JS host
