Angular Router

Chapter 10. Events

The router provides an observable of navigation events. Any time the user navigates somewhere, or an error is thrown, a new event is emitted. This can be useful for setting up monitoring, troubleshooting issues, implementing error handling and so on.

Enable tracing

The very first thing we can do during development to start troubleshooting router-related issues is to enable tracing, which will print out every single event in the console.

@NgModule({
  import: [RouterModule.forRoot(routes, {enableTracing: true})]
})
class MailModule {
}
platformBrowserDynamic().bootstrapModule(MailModule);
