In this chapter, we've explored the use of Node.js for creating RESTful APIs. We've considered various uses of APIs and some techniques for designing them. Looking at aspects such as HTTP codes and input validation, we've considered common problems that are dealt with when creating and maintaining APIs. Despite this, there are still many areas of API design and development that haven't been considered.
The best way to continue improving your knowledge about API design and creation is to start making your own, whether at work or through personal projects. The code we've created throughout the exercises in this chapter can be used as a jumping-off point. Try expanding on what we've done here to create your own endpoints and eventually your own APIs.
In the next chapter, we'll talk about code quality. This will include techniques for writing readable code as well as techniques that can be used to test our code. Those techniques can be used...
