Unified Package Manager for Node.js and Bun

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 when available.

✅ Minimal implementation.

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