REST-Rails API前端

Question

I want to create a Rails + React.JS application and I've seen that most of the tutorials on the web mention about REST API. The data I want to be served through JSON

I understand what's a REST API but what I do not understand is how does the frontend gets served to the user?

Do I need to have 2 Rails projects , one for the API , from which we get JSON data (like users etc) and one for the View Layer which will return an HTML with plenty of javascript ?

And what if I create only a simple rails app ( not API), which has controllers for the view-layer (to render html/javascript ) and controllers for json data (which would be " API ") ? Would that be a good practice or not?

All I want to create is an app that: you visit a page, say /users/1 , get the HTML content (which would be mostly referencing scripts and that's it) and another route responsible for json data from which we pull data, let's say /api/users/1.json (which would be a namespace route to match the api folder in controllers).

What you want to do here is to use react-rails. It also allows server side rendering (no REST API).

https://github.com/reactjs/react-rails

Just run gem 'react-rails' , bundle install , and rails g react:install

Then you just list components to your application.js file like below and can start using react components from automatically created folder at app/assets/javascripts/components/

//= require react
//= require react_ujs
//= require components
