Home – NAPI-RS

NAPI-RS is a framework for building pre-compiled Node.js addons in Rust.

Rustify Node.js in few lines!

lib.rs

use napi_derive::napi;
 
#[napi]
fn fibonacci(n: u32) -> u32 {
  match n {
    1 | 2 => 1,
    _ => fibonacci(n - 1) + fibonacci(n - 2),
  }
}

Compatible with both CommonJS and esm, with auto generated .d.ts file:

main.mjs

import { fibonacci } from './index.js'
 
// output: 5
console.log(fibonacci(5))

main.cjs

const { fibonacci } = require('./index')
 
// output: 5
console.log(fibonacci(5))

🚀 Bring native performance for Node.js

👷‍♂️ Memory safe, guaranteed by Rust compiler

⚡️ Zero copy data interactive between Rust & Node.js via Buffer and TypedArray

⚙️ Parallelism in few lines
