App Reducer

Create application reducer and meta reducer.

Also like normal NgRX apps, add a reducer map to your app.state.ts file. We recommend creating this file in a root state directory, located at src/app/state.

app.state.ts

import { ActionReducerMap, MetaReducer } from '@ngrx/store';
import { IEntityState } from '@briebug/ngrx-auto-entity';
import { environment } from '../../environments/environment';

export interface IAppState {
  // todo: add each entity state interface to our application state interface
}
export type AppState = IAppState;

export const appReducer: ActionReducerMap<AppState> = {
  // todo: add each entity reducer
};

In versions of NgRx Auto-Entity prior to v0.2, the developer was also responsible for including the autoEntityMetaReducer in the app meta reducers collection. As of version 0.2 of the library, import of the NgrxAutoEntityModule with the .forRoot() call is all that is necessary to include the meta reducer.

If you are upgrading from a version prior to v0.2, you should remove the autoEntityMetaReducer from your app meta reducers!

With NgRx 8, runtime checks have replaced the need to use the storeFreeze meta reducer. As such, a standard state configuration no longer requires any meta reducers.
