Use when working with the bun CLI — Bun's all-in-one JavaScript runtime and toolkit. Covers the CLI command reference (install, add, remove, run, build, test, x, create, init, pm, upgrade, link, unlink), bunfig.toml configuration, environment variables, the package manager and lockfile, the test runner, the bundler, the Bun runtime API (Bun.serve, Bun.file, Bun.spawn, Bun.write, hashing, transpiler), the Bun shell ($ template literal), module resolution and loaders, and globals. Triggers on: "bun", "bunx", "bun install", "bun add", "bun remove", "bun run", "bun build", "bun test", "bun x", "bun create", "bun init", "bun pm", "bun upgrade", "bun link", "bun unlink", "bunfig.toml", "bun.lock", "Bun.serve", "Bun.file", "Bun.write", "Bun.spawn", "Bun.hash", "Bun.password", "bun:test", "Bun.build", "Bun.Transpiler", "bun shell", "$ template", "import.meta", "JavaScriptCore", "Bun.serve", "HTMLRewriter", "Bun.SQL", "Bun.RedisClient", "Bun.Glob", "Bun.plugin", "bun:ffi".

Comprehensive reference for the Bun CLI (https://bun.sh/docs), covering the command reference, configuration, package manager, test runner, bundler, runtime API, shell, and module resolution. Bun is an all-in-one JavaScript runtime built on JavaScriptCore (not V8), with a native bundler, transpiler, test runner, and package manager written in Zig and C++.
Source file (.js/.ts/.jsx/.tsx)
→ transpiler (JS/TS/JSX → vanilla JS, dead code elimination)
→ module resolver (node_modules, exports field, tsconfig paths)
→ runtime (JavaScriptCore engine executes)
→ globals (Web API + Node.js + Bun-specific)
→ Bun API (serve, file, spawn, write, hash, etc.)
