Rust bindings for writing safe and fast native Node.js modules.

Getting started

Once you have the platform dependencies installed, getting started is as simple as:

$ npm install -g neon-cli
$ neon new my-project

See the Getting Started guide for details.

Platform Support

Operating Systems

Linux macOS Windows

Node.js

Node 6 Node 8 Node 10

Support for LTS versions of Node and current are expected. If you're using a different version of Node and believe it should be supported, let us know.

Rust

Neon supports Rust stable version 1.18 and higher. We test on the latest stable, beta, and nightly versions of Rust.

A Taste...

fn make_an_array(mut cx: FunctionContext) -> JsResult<JsArray> {
    // Create some values:
    let n = cx.number(9000);
    let s = cx.string("hello");
    let b = cx.boolean(true);

    // Create a new array:
    let array: Handle<JsArray> = cx.empty_array()?;

    // Push the values into the array:
    array.set(&mut cx, 0, n)?;
    array.set(&mut cx, 1, s)?;
    array.set(&mut cx, 2, b)?;

    // Return the array:
    Ok(array)
}

register_module!(mut cx, {
    cx.export_function("makeAnArray", make_an_array)?;
})
