About esbuild

esbuild achieves 10-100x faster builds than Webpack and Parcel by being written in Go with heavy parallelization. A full application bundle that takes 60 seconds in Webpack completes in under a second.

Handles JavaScript, TypeScript, JSX, and CSS without additional loaders or configuration. Tree shaking, code splitting, source maps, and minification are built in. Used as the production bundler inside Vite.

Plugin API enables custom transformations and resolution. Single Go binary with zero JavaScript dependencies makes installation instant and reproducible.

Ideal as a fast build tool for libraries, CLI tools, and server-side code. For full-featured application bundling with HMR and dev server, Vite (which uses esbuild internally) is typically preferred.

SWC vs esbuild — Rust and Go JavaScript Compilers Compared

SWC and esbuild represent the new generation of JavaScript build tools that replaced Babel and webpack with orders-of-magnitude faster compilation. SWC is written in Rust and focuses on transpilation and minification as a Babel replacement, powering Next.js and Parcel. esbuild is written in Go and provides an integrated bundler, transpiler, and minifier in a single tool. Both deliver remarkable speed but differ in scope, extensibility, and ecosystem integration.
