Rustify Node.js in few lines!#

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:

import { fibonacci } from './index.js'

// output: 5
console.log(fibonacci(5))

const { fibonacci } = require('./index')

// output: 5
console.log(fibonacci(5))
