Note: Future updates to this package have moved to the main package rooks. All hooks now reside in a single package which you can install using

npm install rooks

or

yarn add rooks

Rooks is completely treeshakeable and if you use only 1 of the 50+ hooks in the package, only that hook will be bundled with your code. Your bundle will only contain the hooks that you need. Cheers!
