Our app's architecture
The frontend layer of the recipes book app will be implemented in Angular 12 and will communicate with a RESTful backend based on Node.js.
Note
The aspects related to the backend are not the subject of this book and will not be detailed. You can find the ready-to-use fake backend in the GitHub repository: https://github.com/PacktPublishing/Reactive-Patterns-with-RxJS-7-in-Angular-applications.
The frontend of the recipes book app is pluggable to any RESTful backend. Therefore, you can use pretty much any other technology for the backend. All communications will be performed through the HTTP Client module and will request REST controllers in the backend.
