To me this underscores the most unspoken point. Redux is meant for when you specifically want to build your app around redux. It's not meant to tack on some global store to an existing UI. It is UI agnostic way of separating your business logic and side effects from the UI iself (which could be react, vue, angular, whatever)

For the most part, yeah.

Now, the other app my team works on is built with Backbone/Marionette. We've introduced React and Redux to it, and are progressively refactoring over time. It works, although we've got some rather ugly code in several places (some data is in Backbone collections, other data is in Redux, and occasionally some bits of data are mirrored in both places).

I wrote about some of the techniques we're using to integrate them here: https://blog.isquaredsoftware.com/2017/07/react-redux-backbo...
