This question is more of best practices than related to code, but I've been searching online for this for sometime without much progress. 

We have an existing AngularJs (1.x) app and we are trying to add simple React components in it. Adding React is not the problem. I want to know if it makes sense to add Redux to this as well? I know that Redux is an app level state component, but since we are adding React in parts only, would using Redux be an unnecessary overkill in this case? I mention Redux only assuming that the complexity and number of React components might grow in the future. I wouldnt consider Redux if we we had to add only a handful of simple React components.

Here is an [excellent post](https://medium.com/@gethylgeorge/how-to-hook-reactjs-to-your-existing-angularjs-1-x-app-5ab1ac59c0c1) that adds React to an Angular app, but not Redux.
