I require the use of the main codebase that uses ParseBackboneJs to be converted to regular firebase.js still using the templates. There are 3 main features namely (login,signup) , enter data and save to backend and push notifications. The push notifications can wait for the mean time but what I require mainly is dumping parse and using firebase.
