Thanks for your reply! I think that's​ good choice to make my back-end with firebase due to the little time that I have.

As I recently understood, I have only 3 weeks and 4 days for creating my project, so I think I've no time to research all these back-end technologies and that's sad. I will probably use firebase for my purpose and I absolutely ready to give some help about React/Redux if I'll know answer on your question. That is my skype - sanyk_strelok (dont smile I was much younger when created this account)

Near one month I guess. The most of time i've spend for understanding how to do good code. How to use React and Redux itself not so hard for understanding, that is only JavaSrcipt. Mechanism of middlewares working(inside) was pretty difficult to realize:)

Hi dude, thanks for your reply:) I have used several resourses for a learning purpose: React - off. documentaion, egghead, a lot of articles with "best practices"(recently I found this article that composes bits that I learned from other articles) and various real apps examples, ofc. Redux - off.doc, egghead and also articles that have allowed me not to write bad code(as much as possible). P.S. sorry for my broken English
