Bun is a fast JavaScript runtime and toolkit that ships runtime, package manager, test runner, and bundler in a single binary. It can replace Node.js workflows by running existing Node.js projects with bun install and bun test, or by running the entire app on Bun, with JavaScript/TypeScript executed on JavaScriptCore and Node.js APIs working as-is. It bundles TS/JSX/CSS/HTML for browsers and servers and includes a dev server with hot reload and Jest-compatible testing, delivering performance advantages across the full development workflow.
