How to write a server for react app in ruby?

Question

Ruby on Rails

Give an idea of ​​how to write a server for react. I heard about the rest api, but I really don’t understand what the point is

Answer 1

Do you have any experience with Ruby? If not, then it's probably too early to start writing web services.
For a quick entry, I recommend that you first familiarize yourself with the lightweight Sinatra + Sinatra JSON API framework .
