A few months back I wrote about headless WordPress on the Arroyo Labs blog, http://blog.arroyolabs.com/2016/02/headless-wordpress-a-primer/

Since then I have made a bunch of improvements to the package on github.  Take a look and let me know what you think.  We’ll continue to make improvements to the code to make working with WordPress that much easier.  https://github.com/ArroyoLabs/erdiko-wordpress
