Suppose I am currently on the page which has the URL /user/:id . Now from this page I navigate to next page :id/posts.
Now Is there a way, so that i can check what is the previous URL, i.e. /user/:id.
Below are my routes
export const routes: Routes = [
{
path: 'user/:id', component: UserProfileComponent
},
{
path: ':id/posts', component: UserPostsComponet
}
];
You can subscribe to route changes and store the current event so you can use it when the next happens
previousUrl: string;
constructor(router: Router) {
router.events
.pipe(filter(event => event instanceof NavigationEnd))
.subscribe((event: NavigationEnd) => {
console.log('prev:', event.url);
this.previousUrl = event.url;
});
}
