As of version Angular 7.1, there is still no mention of the calendar component in the official Angular Material docs. The form controls include a datepicker component, which internally uses a calendar popup for date entry. However, if you want to display a calendar that is always open, the date picker is not feasible. In this post, I will talk about the calendar component that is available as part of the Angular Material library. I will also show how to use it to get date input from the user through events.
When using a guard to protect a route, or using a resolver to pre-fetch data, we can have a delay between the moment we navigate to a route, and the moment that our component is displayed. Notifying the user that something is happening in the background can greatly improve the User Experience.
