Summary
The first version of our backend service is now complete, allowing us to create, read, update, and delete blog posts via a REST API (using Express), which then get stored in a MongoDB database (using Mongoose). Additionally, we have created service functions with unit tests, defined using the Jest test suite. All in all, we managed to create a solid foundation for our backend in this chapter.
In the next chapter, Chapter 4, Integrating a Frontend Using React and TanStack Query, we are going to integrate our backend into a React frontend using TanStack Query, a library to handle asynchronous state and thus data fetched from our server. This means that, after the next chapter, we will have developed our first full-stack application!
