Above: the time to do a production bundle of 10 copies of the three.js library from scratch using default settings, including minification and source maps. More info here.

Our current build tools for the web are 10-100x slower than they could be. The main goal of the esbuild bundler project is to bring about a new era of build tool performance, and create an easy-to-use modern bundler along the way.

Major features:

Extreme speed without needing a cache
JavaScript, CSS, TypeScript, and JSX built-in
A straightforward API for CLI, JS, and Go
Bundles ESM and CommonJS modules
Bundles CSS including CSS modules
Tree shaking, minification, and source maps
Local server, watch mode, and plugins
