Bun's package manager is significantly faster than npm/yarn/pnpm:
Manages dependencies with Bun package manager: installs/removes/updates packages, handles workspaces and lockfiles, runs scripts, migrates from npm/yarn/pnpm.
Installs dependencies from package.json using Bun package manager. Supports --frozen-lockfile for CI/reproducible builds and --production for deployment. Verifies node_modules, peer deps, and runs prepare hooks.
Boosts JS/TS development speed with Bun: native TS/JSX, built-in bundler, test runner, and faster package installs. Start new projects, migrate from Node, or optimize dev tooling.
