Uses node's new worker thread API with lightweight wrappers to minimize package size.
Supports async/await. Submit a function to a thread pool to run it and wait for the returned Promise to resolve.
Worker threads can share memory via shared array buffers and synchronize with the Atomic API
With npm,
npm i node-threadpool # OR yarn add node-threadpool
import { Executors } from "node-threadpool";
// creates a thread pool with 4 threads
const pool = Executors.newFixedThreadPool(4);
// these execute in parallel (as long as the pool size >= 2)
const result1 = pool.submit(async () => "done 1");
const result2 = pool.submit(async () => "done 2");
console.log(await result1); // joins and prints "done1"
console.log(await result2); // joins and prints "done2"
COMPATIBILITY NOTE
Requires node 10.5+. You must run node with the --experimental-worker flag enabled.
NODE_OPTIONS=--experimental-worker ./server.js
