Access to Redux store from another module?

A question about structuring my code. I have a module that connects to an external server and supplies updates that want to go into the Redux store. It must run on the server, and I am (successfully) initializing and starting the module from server.js, right before the call to server.listen()

I want that module to be able to send actions to the Redux store. I think I see how to handle all the reducers, etc. My question:

What's the "right way" to make my module aware/able to access the redux store?

(I see that app.use() in server.js calls createStore(). I thought about passing store as a parameter to my module's init(), but that seems to be called with every request...)

Update: Oh, wait. It could be worse than I thought. The store is constantly being updated/replaced - how can my module continually track the current store? Thanks.
