  "description": "Use Bun as a unified runtime, package manager, and bundler to speed up Node development and builds by several times.",
  "keyword": "Bun in practice",
  "summary": "Bun unifies runtime, package manager, and bundler into one toolchain, beating Node on startup and install speed. It pairs especially well with AI Coding workflows, replacing npm + esbuild with one command. Three steps: (1) bun install to add dependencies; (2) bun run dev to start the server; (3) bun build to produce an optimized bundle. Bottom line up front: migrating a Node project to Bun usually needs zero code changes for an instant speed boost — best for local dev and scripts. Common pitfalls are Bun fs and a few other APIs differing from Node, and legacy native modules missing under Bun that force a fallback to Node.",

      "q": "Can Bun fully replace Node?",
      "a": "For most use cases yes, but if production depends on Node-only native modules, verify compatibility first."
    },
    {
      "q": "Does Bun conflict with pnpm?",
      "a": "No conflict. Bun ships its own package manager, but you can keep pnpm for dependencies and use Bun purely as a runtime."
