promote-peer-dependencies

Searches registered dependencies for peers, and yarn adds them to your project.

Usage:

yarn global add promote-peer-dependencies
cd [your project root]
promote-peer-dependencies

Also, this tool is accessible in code:

const ppd = require('promote-peer-dependencies');
ppd();

Note There is a package npm-install-peers that predated this one and is designed for use as a global command line tool. This does that, but is available as a simple function via require() for integration into other projects.
