Steps to create a personalized loading screen using Angular

I am looking to enhance the loading screen for our angular 9 application. Currently, we are utilizing

<div [ngClass]="isLoading ? 'loading' : ''>

in each component along with the isloading: boolean variable.

Whenever an API call is made, we switch the value of this variable to true which triggers a spinning wheel to appear, freezing the app until the API call completes. Once finished, we set back the value to false and display the content to the user.

I am interested in creating a customized loading screen to provide additional information. Does anyone have any suggestions or solutions for implementing this?

Show a loading spinner using the ngx-spinner library when making calls to a back end service:

Here is an example:

Prior to making the back end call, include this line of code:

this.spinner.show();

In your template, you can add the following:

<ngx-spinner [fullScreen]="true" type="ball-clip-rotate-multiple" size="medium" bdColor="rgba(32, 55, 77, 0.85)">
  <p class="loading" ><Strong>Please wait ...</Strong></p>
</ngx-spinner>

Once the service returns results, use this code:

this.spinner.hide();

When developing my applications, I always make sure to include a loading state component. It's important to cover all aspects of UI components, including:

blank state (Content is loaded but empty, such as an empty list)
loading state (Content is still loading)
partial state (Certain parts of the view are not yet complete or working on certain elements, like a long list with few entries)
error state (Something has gone wrong and cannot be recovered)
ideal state (Perfect scenario where content is available and well-structured)

In my approach, I create components specifically for error, loading, and blank states, while incorporating ideal and partial states into other components. By providing inputs, these components can adapt based on contextual information. For instance, in a project view that is empty, a message like "You have no projects yet" could be displayed by the empty state component.

To implement this, you can use:

<ng-container *ngIf="isLoading" ><app-loading-state></app-loading-state></ng-container>
<ng-container *ngIf="error" ><app-error-state [reason]="Failed to load"></app-error-state></ng-container>
<ng-container *ngIf="!isLoading" ><!-- Content of your view here. --></ng-container>
