Rollup is a JavaScript module bundler that compiles small ES modules into larger bundles for libraries and applications, with tree-shaking, code-splitting, and a plugin API. It is the bundler behind Vite and supports output formats like ES modules, CommonJS, UMD, and SystemJS.

Use cases

• bundle a javascript library for npm
• tree-shake unused code from es modules
• build a browser iife bundle from modules
• code-split an app by dynamic imports
• set up a custom build pipeline with a plugin api

When to choose

• you are publishing an ES module library and want minimal, tree-shaken output
• you need a configurable bundler with a rich plugin ecosystem
• you want standards-based ES module handling rather than CommonJS-first tooling

When to avoid

• you need a batteries-included dev server and HMR out of the box (use Vite)
• your project is heavily CommonJS-based without plugin setup
• you need bundling for non-JavaScript assets with zero configuration
