nanothreads

A super-fast, super-powerful Worker-based multi-threading library for the browser and Node.js.

Nanothreads is only ~2 KB for browsers, ~2.3 KB for Node.js, making it a super tiny alternative to tinypool, threads.js and others!

[Benchmarks] | [Docs]

Overview

  • Zero-dependencies ❌
  • Tiny bundle size! 🙈
  • 100% Fully Typed 💯
  • Super fast, super efficient 🔥
  • Works both in the browser, and Node 👀

Install

npm install nanothreads

pnpm add nanothreads

yarn add nanothreads

Basic Usage

Importing

// Browsers
import { ThreadPool } from "nanothreads/browser";

// Node.js
import { ThreadPool } from "nanothreads";

Note: Browsers must specify the import path as nanothreads/browser.

Kitchen Sink

import { InlineThread, Thread, ThreadPool } from "nanothreads";

type Quote = {
	quote: string;
};

// Inline Thread
const inline_thread = new InlineThread<[name: string], string>((name) => {
	return "Hello " + name;
});

// Thread from a script
const thread = new Thread<number, number>("./worker.ts");

// Thread Pool from an inlined function
const pool = new ThreadPool<string, Quote>({
	task: (url) => {
		return fetch(url)
			.then((res) => res.json())
			.then((json) => json as Quote);
	},
	count: 5, // number of threads = 5
});

// Using the thread pool
for (let idx = 0; idx < 10; idx++) {
	pool.exec("https://api.kanye.rest").then((quote) => {
		// output: "{ quote: "Man... whatever happened to my antique fish tank?" };"
		console.log(JSON.stringify(quote));
	});
}

const greetings = await inline_thread.send("Kanye"); // output: "Hello Kanye"

const my_number = await thread.send(4); // output: 8

// Cleanup when done!
await thread.terminate();
await inline_thread.terminate();
await pool.terminate();
