Adding Google Sign In With Rails and React
For this blog post we will be using ruby version 2.4.0 and rails version 5.1.4 as backend and React/Redux as frontend. Adding Google Sign in functionality in your application can be done in two popular ways.
Adding google sign in functionality in the frontend with google api client
Adding google sign in functionality logic in the backend server.
If your application has separate backendend with APIs feeding data to the frontend React application, I suggest you to follow the step 2. If you want yo enhance your application security, then you implement both.
