When should I add Redux to a React app?

Question

I\'m currently learning React and I am trying to figure out how to use it with Redux for building a mobile app. I\'m kind of confused on how the two are related/usable toget

I've found that the ideal path for adding Redux to an application/stack is to wait until after you/app/team are feeling the pains that it solves. Once you start seeing long chains of props building up and being passed down through multiple levels of components or your finding yourself orchestrating complex state manipulations/reads, that could be a sign that your app may benefit from introducing Redux et al.

I recommend taking an app that you've already built with "just React" and see how Redux might fit into it. See if you can gracefully introduce it by plucking out one piece of state or set of "actions" at a time. Refactor towards it, without getting hung up on a big bang rewrite of your app. If you're still having trouble seeing where it might add value, then that could be a sign that your app is either not large or complex enough to merit something like Redux on top of React.

If you haven't come across it yet, Dan (answered above) has a great short-video series that walks through Redux on a more fundamental level. I highly suggest spending some time absorbing pieces of it: https://egghead.io/series/getting-started-with-redux

Redux also has some pretty great docs. Especially explaining a lot of the "why" such as http://redux.js.org/docs/introduction/ThreePrinciples.html
