create-react-app-redux | React Router , Redux , Redux Thunk | Router library

There's an open issue that would address this, but until that is done it requires a hack. I called combineReducers with something like this (I am using immutable js. but if you're not it's simple to convert to that)

I assume the api call will be made after your page loads up i.e. you must be firing the action in componentWillMount() or componentDidMount().

The api call is asynchronous, so console.log( FETCHED_COUNT[0] ) is always going to be undefined since the axios promise will not be resolved by the time the console.log(...) statement is executed.

If you put console.log inside axios().then((res) => {....// put console.log here}), then you'll see expected response. So you need to update state AFTER the api call has returned.

For such circumstances, its best you initialize redux initial state with an empty array.
