+# Router Events Simplified
+
+`RouterEvents` is a utility service to provide an easy implementation for one of the most frequent needs in Angular templates: `TrackByFunction`. Please see [this page in Angular docs](https://angular.io/guide/template-syntax#ngfor-with-trackby) for its purpose.
+
+
+
+
+## Benefit
+
+You can use router events directly and filter them as seen below:
+
+```js
+import {
+  NavigationEnd,
+  NavigationError,
+  NavigationCancel,
+  Router,
+} from '@angular/router';
+import { filter } from 'rxjs/operators';
+
+@Injectable()
+class SomeService {
+  navigationFinish$ = this.router.events.pipe(
+    filter(
+      event =>
+        event instanceof NavigationEnd ||
+        event instanceof NavigationError ||
+        event instanceof NavigationCancel,
+    ),
+  );
+  /* Observable<Event> */
+
+  constructor(private router: Router) {}
+}
+```
+
+However, `RouterEvents` makes filtering router events easier.
+
+```js
+import { RouterEvents } from '@abp/ng.core';
+
+@Injectable()
+class SomeService {
+  navigationFinish$ = this.routerEvents.getNavigationEvents('End', 'Error', 'Cancel');
+  /* Observable<NavigationCancel | NavigationEnd | NavigationError> */
+
+  constructor(private routerEvents: RouterEvents) {}
+}
+```
+
+`RouterEvents` also delivers improved type-safety. In the example above, `navigationFinish$` has inferred type of `Observable<NavigationCancel | NavigationEnd | NavigationError>` whereas it would have `Observable<Event>` when router events are filtered directly.
+
+
+
+
+## Usage
+
+You do not have to provide `RouterEvents` at the module or component level, because it is already **provided in root**. You can inject and start using it immediately in your components.
+
+
+### How to Get Specific Navigation Events
+
+You can use `getNavigationEvents` to get a stream of navigation events matching given event keys.
+
+```js
+import { RouterEvents } from '@abp/ng.core';
+import { merge } from 'rxjs';
+import { mapTo } from 'rxjs/operators';
+
+@Injectable()
+class SomeService {
+  navigationStart$ = this.routerEvents.getNavigationEvents('Start');
+  /* Observable<NavigationStart> */
+
+  navigationFinish$ = this.routerEvents.getNavigationEvents('End', 'Error', 'Cancel');
+  /* Observable<NavigationCancel | NavigationEnd | NavigationError> */
+
+  loading$ = merge(
+    this.navigationStart$.pipe(mapTo(true)),
+    this.navigationFinish$.pipe(mapTo(false)),
+  );
+  /* Observable<boolean> */
+
+  constructor(private routerEvents: RouterEvents) {}
+}
+```
+
+
+### How to Get All Navigation Events
+
+You can use `getAllNavigationEvents` to get a stream of all navigation events without passing any keys.
+
+```js
+import { RouterEvents, NavigationStart } from '@abp/ng.core';
+import { map } from 'rxjs/operators';
+
+@Injectable()
+class SomeService {
+  navigationEvent$ = this.routerEvents.getAllNavigationEvents();
+  /* Observable<NavigationCancel | NavigationEnd | NavigationError | NavigationStart> */
+
+  loading$ = this.navigationEvent$.pipe(
+    map(event => event instanceof NavigationStart),
+  );
+  /* Observable<boolean> */
+
+  constructor(private routerEvents: RouterEvents) {}
+}
+```
+
+
+### How to Get Specific Router Events
+
+You can use `getEvents` to get a stream of router events matching given event constructors.
+
+```js
+import { RouterEvents } from '@abp/ng.core';
+import { ActivationEnd, ChildActivationEnd } from '@angular/router';
+
+@Injectable()
+class SomeService {
+  moduleActivation$ = this.routerEvents.getEvents(ActivationEnd, ChildActivationEnd);
+  /* Observable<ActivationEnd | ChildActivationEnd> */
+
+  constructor(private routerEvents: RouterEvents) {}
+}
+```
+
+
+### How to Get All Router Events
+
+You can use `getEvents` to get a stream of all router events without passing any event constructors. This is nothing different from accessing `events` property of `Router` and is added to the service just for convenience.
+
+```js
+import { RouterEvents } from '@abp/ng.core';
+import { ActivationEnd, ChildActivationEnd } from '@angular/router';
+
+@Injectable()
+class SomeService {
+  routerEvent$ = this.routerEvents.getAllEvents();
+  /* Observable<Event> */
+
+  constructor(private routerEvents: RouterEvents) {}
+}
+```
