Summary

Socket.IO is one of the most popular Node.js tools used to develop real-time applications. In this chapter, we successfully used it to build an interactive chat. The users in our network were able to not only post content that appeared in their feeds but also exchange messages with other users in real time. The WebSockets technology made this possible.

The next chapter is dedicated to testing. We will learn about a few popular modules that will help us write tests.
