What is Million?

Million is a drop-in replacement for React with a lightweight (<1kb) Virtual DOM. It's really fast and makes it easy to create user interfaces.

Oh man... Another /virtual dom|javascript/gim library? I'm fine with React already, why should I bother switching?

Million makes creating user interfaces as easy as React, but with faster performance and smaller bundle size for the end user. By computing the user interface beforehand with a compiler, Million reduces the overhead of traditional Virtual DOM.

Okay cool... but why should I use Million if I can just use Preact if I need something a bit more lightweight?

While alternative libraries like Preact reduce bundle sizes by efficient code design, Million takes it a step further by leveraging compilation to make a quantum leap in improving bundle size and render speed.

Think of it as if React's API and Svelte's compiler had a baby. A baby with super speed! 👶🚀

Why Million?

Advantages	Use Cases
⚛️ Familiar React API (with million/react) 🦁 Built for libraries that compile 📦 Lightweight bundle size (<1kb brotli+min) ⚡ Fast runtime operations 🛠️ Composable using drivers, sensible by default	Write React with a fast Virtual DOM Efficiently updating nodes Creating UI libraries Turning MPAs into SPAs Use granular HMR updates

Note: Million now supports experimental React compatibility.

Installing Million

Inside your project directory, run the following command:

npm install million

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.

Module	Description
million	The main Virtual DOM with all of Million's core.
react	A module that gives React compatibility for Million.
router	A module that enables SPA routing for MPAs.
jsx-runtime	A module that provides JSX runtime utilities
html	A module that provides factory functions and tagged template for easier virtual node creation (JSX alternative)
morph	A module for morphing HTML with just DOM nodes (like morphdom) inside the page. Works great for implementing hot refresh in SSR frameworks
utils	A module that provides conversion utilities for virtual nodes, DOM nodes, and HTML strings
vite-plugin-million	A Vite plugin that optimizes virtual node tree ("the compiler")
