Redux; accessing other parts of the state when using composed reducers via combineReducers

Question

Update

Thanks to @Dominic Tobias and @gabdallah for spotting my embarrassing mistake.

The correct answer is of course;

so

Answer 1

Back in the old days before things got simpler for a developer people would listen to the popstate event on the history object ;)

It looks like the required info is on the action?

history.listen((error, nextRouterState) => {
 ...
 store.dispatch(routerDidChange(nextRouterState));

and the action:

export function routerDidChange(state) {
  return {
    type: ROUTER_DID_CHANGE,
    payload: state
  };
}

So try checking action.payload.

However your switch statement is using action instead of action.type so there's something fishy going on there.. You shouldn't need to do action = {} either - see http://redux.js.org/docs/basics/Reducers.html
