In this chapter, we first learned how to set up an API server from a JSON file. Then, we learned how to request resources using Effect and State/Reducer Hooks. Next, we learned how to request resources using the axios and react-request-hook libraries. Finally, we learned how to prevent unnecessary re-rendering using React.memo, and how to lazily-load components with React Suspense.

In the next chapter, we are going to add routes to our application, and learn how to use Hooks for routing.
