redux-pubsub.js

function firstReducer(state, action) {
  if (action.type === 'LOGIN_PENDING') console.log('firstReducer log');
  return state;
}

function secondReducer(state, action) {
  if (action.type === 'LOGIN_PENDING') console.log('secondReducer log');
  return state;
}

const reducer = combineReducers({ firstReducer, secondReducer })
const store = createStore(reducer);

// all subscribers listened to the triggered event
store.dispatch({ type: 'LOGIN_PENDING' });

// firstReducer log
// secondReducer log
