when user changes his url by hand your application will be unloaded and loaded again. you can do some hacks with javascript like write url on unload, and then return it back on load

window.addEventListener('beforeunload', function(e) {
  localStorage.setItem("appUnloading", JSON.stringify({time: Date.now(), url: location.pathname}));
export class GuardForAllRoutes {
  constructor(private router: Router) {}
  canActivate() {
    const appUnloadingState = localStorage.getItem("appUnloading");
    let time, url;
    if(appUnloadingState) {
      {time, url} = JSON.parse(appUnloadingState);
     if(Date.now() - time < 10000) { //let say your page will be loaded for no more that 10 seconds
        return this.router.parse(url); // this won't work on old angular versions. use router.navigate instead

The ** path in the last route is a wildcard. The router will select this route if the requested URL doesn't match any paths for routes defined earlier in the configuration. This is useful for displaying a "404 - Not Found" page or redirecting to another route.


import { HelloComponent } from './hello.component';
import { PageNotFoundComponent } from './page-not-found/page-not-found.component';
const appRoutes: Routes = [
  { path: 'hello', component: HelloComponent },

  { path: '**', component: PageNotFoundComponent } <---
  imports:      [ BrowserModule,RouterModule.forRoot(

    ), FormsModule ],
  declarations: [ AppComponent, HelloComponent, PageNotFoundComponent ],
  bootstrap:    [ AppComponent ]
