esbuild JavaScript Bundlerとは
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.
