tsup is a zero-config bundler for TypeScript libraries, powered by esbuild. It bundles .ts, .tsx, .js, ., and .mjs files into distributable output with a simple CLI.

Use cases

  • bundle a TypeScript library with no config
  • build multiple entry points for an npm package
  • generate dist output for publishing to npm
  • quickly compile ts/tsx files to js
  • replace a complex rollup setup with a simple bundler

When to choose

  • you want fast, zero-config bundling of a TypeScript library
  • you need to build multiple entry points quickly
  • you prefer esbuild speed over rollup/webpack complexity

When to avoid

  • you need actively maintained tooling - the project is no longer maintained and recommends tsdown
  • you need advanced bundling features like CSS (experimental) or complex plugin ecosystems
  • you're bundling a full web application rather than a library
