bun install is Bun's built-in package manager, a fast alternative to npm, yarn, and pnpm. It installs dependencies from package.json into a node_modules folder compatible with Node.js.
The package manager uses a global cache to avoid re-downloading packages and employs the fastest system calls available for writing files.

-d, --dev

Add as development dependency

Pin package to exact version

Install only production dependencies

Skip running lifecycle scripts

Error if lockfile needs update

Force re-download of all packages

Install package globally

Bun uses bun.lock (text-based) as the default lockfile since v1.2. Remove other lockfiles (package-lock.json, yarn.lock, pnpm-lock.yaml) before first install to avoid conflicts.

Bun does not run dependency lifecycle scripts by default for security. Allow-list trusted packages using trustedDependencies in package.json.

Compatible with existing package.json files. Supports workspaces, git/http/tarball dependencies, and custom registries. Some npm-specific features may behave differently.
