Vad är esbuild JavaScript Bundler

esbuild is a JavaScript and CSS bundler written in Go. It's famous for being extremely fast, often 10–100x faster than webpack or Babel. esbuild bundles JavaScript, TypeScript, JSX, and CSS files, minifies them, performs tree-shaking, and generates source maps. It's minimal by design: no plugins, minimal configuration, zero magic. You use it for production builds, CLI tools, and serverless functions where speed and simplicity matter more than flexibility.

❓ Vanliga frågor

Is esbuild production-ready?
Yes, it's used by thousands of teams in production, but it's simpler than webpack and Rspack, some use cases may need plugins.
Does esbuild support code splitting?
Yes, esbuild supports dynamic imports and automatic code splitting; output is clean and optimized.
Can I use esbuild for large projects?
Yes, but for highly complex scenarios (micro-frontends, multiple entry points), Rspack or webpack may be better.
What about CSS support?
esbuild bundles CSS files, but doesn't have advanced features like CSS modules or postcss integration out of the box.
How does esbuild compare to Vite?
esbuild is the bundler; Vite uses esbuild for development and Rollup for production. Vite is higher-level; esbuild is lower-level.
