react-native - React native - how to combine reducers to store socket.io & redux-thunk

Question

I’m trying to combine two different projects. The first is chat app and the second is store app. I have a issue to create the store for the reducers of the projects. How can I add the two reducers to the same store? Thanks

/* chat only */
// const store = applyMiddleware(socketIOMiddleware)(createStore)(reducer);

/* store only */
const store = createStore(rootReducer, applyMiddleware(ReduxThunk));
