DraftJS Utils

An collection of useful utility functions for DraftJS.

I have been using DraftJS in few of my projects. DraftJS is very nice library for creating editors. I wrote a couple of utility functions for myself which I can re-use across my projects. They are well tested. I am open-sourcing them so that others can also leverage. Many of the functions described use ImmutableJS.

npm install draftjs-utils
