All you need is resolver , that can be done from the routes

{ 
    path: 'detail/:id', 
    component: HeroDetailComponent,
    resolve: {
      hero: HeroDetailResolve
    },
},

thanks for the answer, but resolver is already in routes. > resolver readRequest(){ ... this.service.getRequest().subscribe(data => { return data; }) } //router { path: 'detail/:id', component: SomeCompnent, resolve: { item: resolver(class name) }, }

In a resolver you have to return the observable so the Router can subscribe on it and wait for data to be returned.

1/ you forgot to return the observable 2/ you added a useless subscription on it

so try this :

> resolver

readRequest(){
...
  return this.service.getRequest();
}
