In this chapter we discussed the creation of robust APIs using a LoopBack framework, and approached some very important points regarding the web application as a database, relationships between models, and datasources.
We also saw some similarities between Express and Loopback and learned how to use the web interface of API explorer.
We built an interactive interface using the React.js library and approached the main concept of React.js, which is the creation of components.
In the next chapter, we will see how to build a real-time application using some very useful resources from Node.js.
