Angular Material - Badge

The <mat-badge>, an Angular Directive, is used to create a badges which is a small status descriptor for UI elements. A badge typically carries a number or other short set of characters, that appears in proximity to another UI element.

In this chapter, we will showcase the configuration required to draw a badge control using Angular Material.

app.html
