@ngrx/router-store

Bindings to connect the Angular Router with @ngrx/store

Installation

Install @ngrx/router-store from npm:

npm install @ngrx/router-store --save OR yarn add @ngrx/router-store

Nightly builds

npm install github:ngrx/router-store-builds OR yarn add github:ngrx/router-store-builds

Usage

During the navigation, before any guards or resolvers run, the router will dispatch a ROUTER_NAVIGATION action, which has the signature RouterNavigationAction<T>:

/**
 * Payload of ROUTER_NAVIGATION.
 */
export declare type RouterNavigationPayload<T> = {
  routerState: T;
  event: RoutesRecognized;
};

/**
 * An action dispatched when the router navigates.
 */
export declare type RouterNavigationAction<T = RouterStateSnapshot> = {
  type: typeof ROUTER_NAVIGATION;
  payload: RouterNavigationPayload<T>;
};

• Reducers receive this action, throwing an error in the reducer cancels navigation.
• Effects can listen for this action.
• The ROUTER_CANCEL action represents a guard canceling navigation.
• A ROUTER_ERROR action represents a navigation error .
• ROUTER_CANCEL and ROUTER_ERROR contain the store state before the navigation. Use the previous state to restore the consistency of the store.

Setup

import { StoreRouterConnectingModule, routerReducer } from '@ngrx/router-store';
import { AppComponent } from './app.component';

@NgModule({
  imports: [
    BrowserModule,
    StoreModule.forRoot({
      router: routerReducer,
    }),
    RouterModule.forRoot([
      // routes
    ]),
    StoreRouterConnectingModule.forRoot({
      stateKey: 'router', // name of reducer key
    }),
  ],
  bootstrap: [AppComponent],
})
export class AppModule {}
