The journey through SSR has come to an end. You are now able to create a server-side rendered application with React, and it should be clear why it can be useful for you. SEO is certainly one of the main reasons, but social sharing and performance are important factors as well. You learned how it is possible to load the data on the server and dehydrate it in the HTML template to make it available for the client-side application when it boots on the browser.
Finally, you have looked at how tools such as Next.js can help you reduce the boilerplate and hide some of the complexity that setting up a server-side render React application usually brings to the code base.
In the next chapter, we will talk about how to improve the performance of our React applications.
