postinstall-prepare

Run your app's prepare npm script during this package's postinstall script.

Why

Yarn runs the prepare script after yarn, yarn install and yarn add <package> but not after yarn remove <package>. If you add this package to your project, it will execute your project's prepare hook even after a yarn remove <package>. This requires your prepare script to be idempotent, becase it will be run twice for yarn, yarn install, and yarn add <package>
