Cancel Route Navigation from Resolver in Angular 2

In order to cancel route from resolver, you can use observable instead of promise and call: observer.complete() without calling: observer.next()

For example:

 resolve(route: ActivatedRouteSnapshot, state: RouterStateSnapshot){

   return new Observable((observer) => {
     let somePromiseOrObservableToGetDate=?????;

     somePromiseOrObservableToGetDate.then(data => {
       if (data) {
         observer.next(1);
       }
       observer.complete();
     })
       .catch((err: any) => {
         observer.complete();
       });
   });

 } 

and in your example:

let model: MyModel = new MyModel();

return new Observable((observer) => {
  model.init().then((obj: any) => {
    observer.next(obj);
    observer.complete();
  })
    .catch((err: any) => {
      observer.complete();
    });
});
