All reducers will be invoked when an action is dispatched?

Question

I am using combineReducers to combine all the reducers to create the store, does it mean that any action dispatched from any view will trigger all the reducers being invoked

Answer 1

You can ignore actions of specific reducer by using https://github.com/omnidan/redux-ignore

import { combineReducers } from 'redux';
// redux-ignore higher-order reducer
import { ignoreActions } from 'redux-ignore'
 combineReducers({
  counter: ignoreActions(counter, [INCREMENT_COUNTER])
});
