Yarn vs NPM – You won’t believe how fast it is

Yarn is the hot new drop-in NPM replacement utility for projects using node.js packages. It's way faster, more stable, and more secure than NPM and you can use it with zero configuration on your end.

In the sample for this video, the NPM install takes between 20 and 30 seconds for just a few packages, while the yarn install takes 4-10 seconds to install all of the node packages.

Yarn is also more predictable across environments, so you don't need to npm-shrinkswrap anything, because Yarn manages the dependency tree with a yarn.lock file automatically.
