@ngrxs/router-store

@ngrxs/router-store library serializes Angular router snapshots for NgRx Router Store. It searches entire route tree and puts only useful attributes into NgRx store.

Installation

1. Make sure that you've installed and setup @angular/router and @ngrx/store.

2. npm install --save @ngrxs/router-store
   

3. Import provideNgrxRouterState in app.config.ts:

   import { ApplicationConfig } from '@angular/core';
   import { provideNgrxRouterState } from '@ngrxs/router-store';
   
   export const appConfig: ApplicationConfig = {
     providers: [
       provideNgrxRouterState()
     ]
   };

3.1. Use NgrxRouterStateModule:

```typescript

import { ApplicationConfig } from '@angular/core';
import { NgrxRouterStateModule } from '@ngrxs/router-store';

@NgModule({
  imports: [NgrxRouterStateModule.forRoot()]
})
export class MyModule {
}

```

4. Done! You can see ngrx-router state in Redux DevTools.
