storeFreeze 和 ngrx8

Question

我刚刚升级到 ngrx/store 版本 8。我注意到 ng 更新已经删除了所有出现的 storeFreeze。也将其从 metaReducer 中删除。

所以我的问题是 - 为什么？

在 ngrx 8 上使用 storeFreeze 有问题吗？

ngrx8 之前：

import { ActionReducerMap, MetaReducer } from '@ngrx/store';
import { storeFreeze } from 'ngrx-store-freeze';
import * as fromGroupMember from './group-member.reducer';
import * as fromDirectoryForm from './directory-filter-form.reducer';

export const metaReducers: MetaReducer<IState>[] =
(localStorage && localStorage.getItem('production') === 'false') ? [storeFreeze] : [];

之后：

import { ActionReducerMap, MetaReducer } from '@ngrx/store';

import * as fromGroupMember from './group-member.reducer';
import * as fromDirectoryForm from './directory-filter-form.reducer';

export const metaReducers: MetaReducer<IState>[] =
(localStorage && localStorage.getItem('production') === 'false') ? [] : [];

Answer 1

已在 8.0.0-rc.1 上添加迁移以删除 ngrx-store-freeze 的用法，根据：

The majority of our users are probably using ngrx-store-freeze to guard against state mutations. We have built-in run-time checks in version 8 to guard against those.

参见github issue。

Answer 2

如果您运行 ng update @ngrx/store，这是迁移的一部分。它还应该添加 runtime checks 作为替代，因为它现在是 ngrx 的一部分：

@NgModule({
  imports: [
    StoreModule.forRoot(reducers, {
      runtimeChecks: {
        strictStateImmutability: true,
        strictActionImmutability: true,
      },
    }),
  ],
})
export class AppModule {}
