Summary
Bun is a fast JavaScript runtime that also handles package management, bundling, and testing in one toolkit. It's a drop-in Node replacement built on JavaScriptCore, and the install speeds really are noticeably faster. Reach for it on new projects where you want a unified toolchain, or when you're deploying to Vercel with Bun runtime support. The skill covers migration from Node (mostly just swap `node` for `bun run`), the difference between text and binary lockfiles across versions, and Bun-specific APIs like the native file reader and HTTP server. Stick with Node if you need maximum ecosystem compatibility or have dependencies with known Bun issues.
