Yarn Berry: a next generation package manager

The recently released Yarn Berry (aka Yarn 2) brings a host of great new features for JavaScript developers. The slick new CLI, more readable output, clear errors, and significant enhancements to workspaces make Yarn Berry a solid upgrade from the already impressive Yarn 1. But with an incredible feature called Plug-n-Play (PnP), Yarn Berry takes a massive leap ahead.

Have you ever thought "I really love dealing with this ginormous node_modules folder." No, and no one else has either! With Yarn Berry and PnP you can forever be free of node_modules. PnP dispenses with the node_modules folder entirely and creates an opportunity for perfect module resolution, faster startup, and instant package installs. Imagine cloning a node app and running it immediately, no lengthy install step required. With PnP and Yarn Berry, this dream is a reality.

Come away with an overview of all the new features and the knowledge you need to migrate your app to Yarn Berry.
