Bun is a new JavaScript run time, similar to Node.js or Deno. Unlike Node.js or Deno, however, Bun is built using WebKit's JavaScriptCore instead of Chrome's V8 engine. Designed as a drop-in replacement for Node.js, Bun is a single binary (written in Zig) that acts as a bundler, transpiler and package manager for JavaScript and TypeScript applications. Since our last volume, Bun has gone from beta into a stable 1.0 release. Bun has been built from the ground up with several optimizations — including fast startup, improved server-side rendering and a much faster alternative package manager — and we encourage you to assess it for your JavaScript run-time engine.

Bun is currently in beta, so expect bugs or compatibility issues with a few Node.js libraries. However, it’s been built from the ground up with several optimizations, including fast startup and improved server-side rendering, and we believe it’s worthwhile to assess.
