Chapter 7. Using Backbone and React for DOM Events

This chapter is going to be the finishing touches on our application. We have built the backend, but this is not very useful unless we have a way of interacting with it. There will be a lot of code being removed, added, and updated. I will try to keep the code changes as localized as possible. I don't want to jump between 13 different files, making small changes. On the other hand, I want to make sure that all code changes happen in a logical order. The following is what we are going to cover in this chapter:

Finishing our Socket.IO events that get and add data to Redis
Creating all our view components with React
Tying our Backbone models to Socket.IO and the components
