esbuild is an extremely fast JavaScript/TypeScript bundler and minifier written in Go. It bundles ESM and CommonJS modules, CSS, JSX, and TSX with tree shaking, minification, source maps, a local dev server, watch mode, and a plugin API.
Use cases
- bundle a javascript or typescript project for production
- minify js and css with source maps
- replace webpack with a much faster build tool
- bundle jsx and tsx for a react app
- run a local dev server with watch mode and rebuilds
- compile typescript without a separate transpiler step
- bundle css including css modules
When to choose
- you need very fast bundling of JS/TS/CSS without heavy configuration
- you want built-in TypeScript and JSX transpilation without Node-based toolchains
- you need tree shaking, minification, and source maps out of the box
- you want a simple CLI, JS, or Go API for builds
When to avoid
- you need advanced webpack-specific loaders or a huge plugin ecosystem
- you need full TypeScript type checking during the build (esbuild strips types without checking)
- you rely on very new or experimental CSS/JS syntax not yet supported
- you need code splitting features beyond what esbuild supports
