Auto redirecting after n seconds using Angular 2

its a-bit sketchy but this will work.

    setTimeout(() => {
          setTimeout(() => {
            this.router.navigateByUrl("/home");
          });
        }, 3400);
      }

You can inject and use Router from @angular/router and navigate in setTimeout.

import { Router } from '@angular/router';

constructor(private router: Router) {}

ngOnInit() {
    // do init at here for current route.

    setTimeout(() => {
        this.router.navigate(['nextRoute']);
    }, 5000);  //5s
}
