What is Million?

Million is an extremely fast and lightweight (<4kb) virtual DOM that makes React components up to 70% faster.

Oh man... Another /virtual dom|javascript/gi framework? I'm fine with React already, why do I need this?

Million works with React. Million makes creating web apps just as easy (It's just wrapping a React component!), but with faster rendering and loading speeds. By using a fine-tuned, optimized virtual DOM, Million.js reduces the overhead of React (try it out here)

TL;DR: Imagine React components running at the speed of raw JavaScript.

Installing Million

Inside your project directory, run the following command:

npm install million

Example Usage

Million.js is a library that enables you to create blocks. A block is a special Higher Order Components (HOCs) that can be used as a React component but are hyper-optimized for rendering speed.

Blocks are essentially components wrapped by block(). Below is an example of a React "counter" component that's been wrapped with Million.js.

import { useState } from 'react';
import { block } from 'million/react';

// Just wrap Counter in a block() function!
const Counter = block(function Counter({ initialCount }) {
  const [count, setCount] = useState(initialCount);
  const handleClick = () => {
    setCount(count + 1);
  };

  return <button onClick={handleClick}>{count}</button>;
});

export default Counter;

Codebase

This repo is a "mono-repo" with modules. Million ships as one NPM package, but has first class modules for more complex, but important extensions. Each module has its own folder in the /packages directory.

You can also track our progress through our Roadmap.

Module	Description
million	The main Virtual DOM with all of Million's core.
react / react-server /	React compatibility for Million.
preact / preact-server /	Preact compatibility for Million.
compiler	The compiler for Million in React.
jsx-runtime	A simple JSX runtime for Million core.
types	Shared types between packages

Acknowledgments

Million takes heavy inspiration from the following projects:

• blockdom (Géry Debongnie) Thank you to Géry pioneering the concept of "blocks" in the virtual DOM. Many parts of the Million.js codebase either directly or indirectly derive from his work.
• voby (Fabio Spampinato) The Million.js "template" concept is derived from Voby's template() API.
• Hack the Wave (Melinda Chang) for their homepage.
• react and turbo for their documentation. Many parts of the current Million.js documentation are grokked and modified from theirs.
• ivi, Preact, and more

Million is being used at companies like Wyze and Dimension, as well as open source work like Quartz, TinyPages, and more.
