Disable url change navigation or direct page access in Angular 7 without authguard?

Related searches

Hi I am looking for a method or suggestions that if user change url to access to different page like this

it will restrict the user and user redirect to same page, is there any method to do without Authguard or without using any Modules ?

my stackblitz project which is not working

Here

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
     }

  }
}

Prevent routing in Angular when user manually changes url in , asked Mar 29 '16 at 7:01 We can add this functionality and prevent the access to some of our A service for eg AuthGuard that implements the CanActivate interface and URL was blank, then the user is directly accessing this page if it will automatically be set back to false, not allowing url to change. At the core of the Angular router lies a powerful URL matching engine which transforms URLs and converts them into router states. In this article, I will show how to use three of the engine’s

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.

app.module:

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 } <---
];
@NgModule({
  imports:      [ BrowserModule,RouterModule.forRoot(
      appRoutes,

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

  • angular.io/guide/router
  • One thing you can do is - creating a service that looks for every route change and restrict routing for specific url and navigating back to previous route
  • Where i need to put this code to works globally in router.ts? or should i need to put in every ts file also it shows cannot find time .
  • you can put event listener in app component on init hook, and attach guard to your root route
  • as you said i put CanActivate function in routing.module but still getting error ERROR in app-routing.module.ts(72,20): error TS2304: Cannot find name 'time'. app-routing.module.ts(73,19): error TS2339: Property 'router' does not exist on type 'AppRoutingModule'.
  • @Andei but now it gives error ERROR in app-routing.module.ts(74,19): error TS1128: Declaration or statement expected. here is link for my app-routing.module.ts link
  • Does it works in your local system because your new updated code has error ERROR in app-routing.module.ts(19,19): error TS2449: Class 'ForbidRedirectByHandGuard' used before its declaration. .
  • I need to return the user to the previous state rather than page not found whenever he is changing url manually
