Where to read about the backend of a mobile application?

Question

Mobile development

Tell me literature or tutorials on raising the backend for a mobile application, but not freebase.

Answer 1

So why read 20 articles. In the doc itself, in the motivation section, everything is briefly and clearly described:
redux.js.org/docs/introduction/Motivation.html
+ they often write that if you think that you don’t need Redux, you really don’t need it
