Yarn 2.0

Edit on GitHub

Node

Why Yarn?

  • it’s not the speed anymore, it’s the change in approaches to dependency management. i like Yarn’s approach and explanation better
  • Plug’n’Play is cool. Instead of installing a bajillion files, you can have just one file called .pnp.cjs instead of a whole folder called node_modules in EVERY project. (React Native isn’t yet supported though).
  • See all available commands with yarn help
1npm i -g yarn
