angular - Ionic 3 ngrx/store reducer 仅在生产模式下不接收调度的操作

Question

我有一个 Ionic 3 应用程序，它使用 web sockets 和 redux 使用 ngrx/store。起初，我的所有代码在开发模式下都运行良好。在浏览器和真实设备中。

但是当我尝试在生产模式 中构建它时。该操作仍在分派(dispatch)，但 reducer 未收到已分派(dispatch)的操作，导致应用程序的状态未更新。

下面是我的 reducer 代码。

import { Action } from '@ngrx/store';

const UPDATE_AVATAR = '[Websokcet] New ORDER';
type Type = UpdateAvatar

export class UpdateAvatar implements Action {
  readonly type = UPDATE_AVATAR;
  constructor(public payload: any) { }
}

export function UpdateAvatarReducer(state: any, action: Type) {
  console.log('ACTION RECEIVED:', state, action)
  switch (action.type) {
    case UPDATE_AVATAR:
      return action.payload;
  }
}

在我的 rootReducers

import { UpdateAvatar, UpdateAvatarReducer } from './reducers/uploadAvatar';

export function rootReducer () {
  return {
    reducers: {
      driverUpdateProfile: DriverUpdateProfileReducer,
    },
  }
}

在我的app.module.ts

import { rootReducer } from '../store/websocket';

// and in the **imports arrays**

StoreModule.forRoot({
  ...rootReducer().reducers
}),

它在开发模式下有效，但在生产模式下无效。为什么？

感谢有人能提供帮助。提前致谢。

Answer 1

我设法通过改变我实现 rootReducer 和 rootActions 的方式来解决问题。我没有导出函数，而是返回了声明的 2 个独立对象。

下面是我的 rootReducer 和 actions

的旧代码

export default function () {
  return {
    reducers: {
      newLocation: NewLocationReducer,
      newOrder: NewOrderReducer,
      orderTaken: OrderTakenReducer,
      driverUpdateProfile: DriverUpdateProfileReducer,
      driverUpdateAvatar: UpdateAvatarReducer,
      newTransaction: NewTransactionReducer,
      updateTransaction: UpdateTransactionReducer,
      orderNewMessage: OrderNewMessageReducer,
    },
    actions: {
      newLocation: NewLocation,
      newOrder: NewOrder,
      orderTaken: OrderTaken,
      driverUpdateProfile: DriverUpdateProfile,
      driverUpdateAvatar: UpdateAvatar,
      newTransaction: NewTransaction,
      updateTransaction: UpdateTransaction,
      orderNewMessage: OrderNewMessage,
    }
  }
}

这是下面的新代码:

export const rootActions = {
  newLocation: NewLocation,
  newOrder: NewOrder,
  orderTaken: OrderTaken,
  driverUpdateProfile: DriverUpdateProfile,
  driverUpdateAvatar: UpdateAvatar,
  newTransaction: NewTransaction,
  updateTransaction: UpdateTransaction,
  orderNewMessage: OrderNewMessage,
}

export const rootReducer = {
  newLocation: NewLocationReducer,
  newOrder: NewOrderReducer,
  orderTaken: OrderTakenReducer,
  driverUpdateProfile: DriverUpdateProfileReducer,
  driverUpdateAvatar: UpdateAvatarReducer,
  newTransaction: NewTransactionReducer,
  updateTransaction: UpdateTransactionReducer,
  orderNewMessage: OrderNewMessageReducer,
}

我将它们声明为两个独立的变量，我认为它比旧的更有条理。
