对我来说，最好的工作是设置initialState而不是state:

  const reducer = createReducer(initialState,
  on(proofActions.cleanAdditionalInsuredState, (state, action) => ({
    ...initialState
  })),

只是对@dan-abramov答案的扩展，有时我们可能需要保留某些被重置的键。

const retainKeys = ['appConfig'];

const rootReducer = (state, action) => {
  if (action.type === 'LOGOUT_USER_SUCCESS' && state) {
    state = !isEmpty(retainKeys) ? pick(state, retainKeys) : undefined;
  }

  return appReducer(state, action);
};

为什么不直接使用return module.exports.default();)

export default (state = {pending: false, error: null}, action = {}) => {
    switch (action.type) {
        case "RESET_POST":
            return module.exports.default();
        case "SEND_POST_PENDING":
            return {...state, pending: true, error: null};
        // ....
    }
    return state;
}

注意:确保你设置动作默认值为{}，你是可以的，因为你不想在检查动作时遇到错误。在switch语句中输入。

npm install redux-reset
import reduxReset from 'redux-reset'
...
const enHanceCreateStore = compose(
    applyMiddleware(...),
    reduxReset()  // Will use 'RESET' as default action.type to trigger reset
  )(createStore)
const store = enHanceCreateStore(reducers)

为了避免Redux引用初始状态的相同变量，我的建议是:

// write the default state as a function
const defaultOptionsState = () => ({
  option1: '',
  option2: 42,
});

const initialState = {
  options: defaultOptionsState() // invoke it in your initial state
};

export default (state = initialState, action) => {

  switch (action.type) {

    case RESET_OPTIONS:
    return {
      ...state,
      options: defaultOptionsState() // invoke the default function to reset this part of the state
    };

    default:
    return state;
  }
};

在服务器中，有一个变量:global。isSsr = true 在每个reducer中，我都有一个const: initialState 要重置存储中的数据，我对每个Reducer执行以下操作:

appReducer.js的例子:

 const initialState = {
    auth: {},
    theme: {},
    sidebar: {},
    lsFanpage: {},
    lsChatApp: {},
    appSelected: {},
};

export default function (state = initialState, action) {
    if (typeof isSsr!=="undefined" && isSsr) { //<== using global.isSsr = true
        state = {...initialState};//<= important "will reset the data every time there is a request from the client to the server"
    }
    switch (action.type) {
        //...other code case here
        default: {
            return state;
        }
    }
}

最后在服务器的路由器上:

router.get('*', (req, res) => {
        store.dispatch({type:'reset-all-blabla'});//<= unlike any action.type // i use Math.random()
        // code ....render ssr here
});
