Unified Package Manager for Node.js

🚧 This project is under development. Please follow issues for the roadmap. 🚧

What does nypm do?

✅ Supports npm, yarn, pnpm and bun out of the box with a unified API

✅ Provides an API interface to interact with package managers

✅ Autodetects project's package manager using package.json and known lockfiles

✅ Auto-installs and use exactly expected version of supported package managers using nodejs/corepack

✅ Minimal implementation

nypm, detects package manager type and version and converts command into package manager CLI arguments. It then uses corepack to execute package manager's command (and download it if necessary).
