If you have [`cargo-binstall`](https://crates.io/crates/cargo-binstall) installed, then you can install the pre-built artifacts by running: ``` cargo binstall wasm-bindgen-cli ``` ## Example Import JavaScript things into Rust and export Rust things to JavaScript. ```rust use wasm_bindgen::prelude::*; // Import the `window.alert` function from the Web. #[wasm_bindgen] extern "C" { 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 with ECMAScript modules! ```js import { greet } from "./hello_world"; greet("World!"); ``` ## Features * **Lightweight.** Only pay for what you use. `wasm-bindgen` only generates bindings and glue for the JavaScript imports you actually use and Rust functionality that you export. For example, importing and using the `document.querySelector` method doesn't cause `Node.prototype.appendChild` or `window.alert` to be included in the bindings as well. * **ECMAScript modules.** Just import WebAssembly modules the same way you would import JavaScript modules. Future compatible with [WebAssembly modules and ECMAScript modules integration][wasm-es-modules]. * **Designed with the ["Web IDL bindings" proposal][webidl-bindings] in mind.** Eventually, there won't be any JavaScript shims between Rust-generated wasm functions and native DOM methods. Because the Wasm functions are statically type checked, some of those native methods' dynamic type checks should become unnecessary, promising to unlock even-faster-than-JavaScript DOM access.

The project aims to maintain a 2-year MSRV policy for libraries (meaning we support Rust versions released within the last 2 years), but with a shorter MSRV policy for the CLI. Changes to the MSRV may be made in patch versions, and will be logged in the CHANGELOG and MSRV history below. ### MSRV History | Version | Library MSRV | CLI MSRV | Date | |---------|--------------|----------|------------| | 0.2.106 | 1.71 | 1.82 | 2025-11-xx | | 0.2.103 | 1.57 | 1.82 | 2025-09-17 | | 0.2.93 | 1.57 | 1.76 | 2024-08-13 | ## License This project is licensed under either of * Apache License, Version 2.0, ([LICENSE-APACHE](LICENSE-APACHE) or http://www.apache.org/licenses/LICENSE-2.0) * MIT license ([LICENSE-MIT](LICENSE-MIT) or http://opensource.org/licenses/MIT) at your option. ## Contribution **[See the "Contributing" section of the guide for information on hacking on `wasm-bindgen`!][contributing]** Unless you explicitly state otherwise, any contribution intentionally submitted for inclusion in this project by you, as defined in the Apache-2.0 license, shall be dual licensed as above, without any additional terms or conditions.
