## Install `wasm-bindgen-cli`
You can install it using `cargo install`:
```
cargo install wasm-bindgen-cli
```
Or, you can download it from the
[release page](https://github.com/wasm-bindgen/wasm-bindgen/releases).
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.

## MSRV Policy
* Libraries that are released on [crates.io](https://crates.io) have a MSRV of v1.71.
* CLI tools and their corresponding support libraries have a MSRV of v1.82.
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 |
