comes with node


  • Facebook created yarn because npm was slow


  • uses symbolic links and caching
    • every dependency is installed once
      • ~/.pnpm-store/
  • if two dependencies (or nested dependencies) have the same grand dependencies,
    • they can just point to the same package
    • no need to install it twice!
  • drop in replacement for npm
  • pnpm patch | pnpm
    • modify the source code of your dependencies

  • don't technically need

  "dependencies": {
    "forma-package": "workspace:*"
