如何從Reducer修改Redux存儲的狀態

Question

下面是我寫的減速器：

function rootReducer(state = rootInitialState, action) {
  const appleState = _.cloneDeep(state.get('apple') || {});
  const orangeState = _.cloneDeep(state.get('orange') || {});

switch(action.type){
case 'appleAction':
  return state.set('apple', action.appleChanges);

case 'orangeAction':
  return state.set('orange', action.orangeChanges);
}

default:
  return state;
}

如果我有一個action.type =='both'並且想要修改狀態為'apple'和'orange'的怎么辦，那么我將如何返回修改后的狀態？

Answer 1

就像是...

case 'both':
return Object.assign({}, state, { apple: action.appleChanges, orange: action.orangeChanges });
