Authenticating Users in SPA using Node, Passport, React and Redux

Implementing user authentication can be a difficult task, because we can use various libraries and authentication strategies. There are a lot of tutorials on this topic, but often times they miss fundamental information or don’t reflect set up of our project. In this blog post, I don’t attempt to write an universal tutorial for user authentication. However, I will point out some parts in authentication flow I didn’t find in other tutorials.
