Summary

In this chapter, we learned all about web sockets and how we can use them to utilize real-time data within our Gatsby applications. Then, we implemented a working visitor count that shows the number of people on the current page, as well as the site as a whole. Visitor count statistics is one of a whole host of possible applications for web sockets within a personal site. Perhaps you could take what you have learned here and try and implement article reactions, polls, or even a chat application?

In the next chapter, we will learn about our final advanced concept – localization. We will learn how we can make our Gatsby site support multiple languages for an international audience.
