wasm-bindgen

Facilitating high-level interactions between wasm modules and JavaScript.

Introduction blog post: "JavaScript to Rust and Back Again: A wasm-bindgen Tale"

Build Status Build status API Documentation on docs.rs

Import JavaScript things into Rust and export Rust things to JavaScript.

src/lib.rs:

#![feature(use_extern_macros)]

extern crate wasm_bindgen;
use wasm_bindgen::prelude::*;

// Import the `window.alert` function from the Web.
#[wasm_bindgen]
extern {
    fn alert(s: &str);
}

// Export a `greet` function from Rust to JavaScript, that alerts a
// hello message.
#[wasm_bindgen]
pub fn greet(name: &str) {
    alert(&format!("Hello, {}!", name));
}

Use exported Rust things from JavaScript!

index.js:

// Asynchronously load, compile, and import the Rust's WebAssembly
// and JavaScript interface.
import("./hello_world").then(module => {
  // Alert "Hello, World!"
  module.greet("World!");
});
