In this chapter, we started with an overview about RESTful APIs. From there we dove into practical topics such as data modeling, defining routes, grouping routes, and creating handlers. We covered the knowledge necessary to write functional web APIs in Go.
We also got our first exposure to the powerful Gin framework, which is very popular for writing production-level RESTful APIs.
In the next chapter, we'll dive deeper into backend web APIs. More advanced topics will be covered like ORMs and security. We will also revisit our application's frontend, and discuss how it connects to the backend that we built.
