Let’s open up up src/application/app.module.ts and add AppRoutingModule into the imports array in AppModule’s @NgModule metadata:
it should insert Every single of Those people components in the route, we’ll incorporate ours to the AppComponent, like so:
Continuing with our example, we will now make a company RouteGuardService import Injectable from '@angular/Main'
Following, we will make a resolver to check here fetch the present todos from our again-stop API using Angular Router.
