Everybody builds chat apps with Socket.IO these days, yet messaging applications are only the tip of the iceberg. Think a moment about it: there are a million of other things you can build within the real-time domain.

In the following post we will start with some basic concepts all the way through exploring what Socket.IO and React can do for us when paired together.

By the end of the article you will build a simple proof of concept.

• What you will learn
