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.
Create Angular Application
Follow the following steps to update the Angular application we created in Angular 6 – Project Setup chapter −
| Step | Description |
|---|---|
| 1 | Create a project with a name materialApp as explained in the Angular 6 – Project Setup chapter. |
| 2 | Modify app.module.ts, app.component.ts, app.component.css and app.component.html as explained below. Keep rest of the files unchanged. |
| 3 | Compile and run the application to verify the result of the implemented logic. |
Following is the content of the modified module descriptor app.module.ts.
import { BrowserModule } from ''@angular/platform-browser'';
import { NgModule } from ''@angular/core'';
import { AppComponent } from ''./app.component'';
import {BrowserAnimationsModule} from ''@angular/platform-browser/animations'';
import {MatBadgeModule, MatButtonModule, MatIconModule} from ''@angular/material''
import {FormsModule, ReactiveFormsModule} from ''@angular/forms'';
@NgModule({
declarations: [
AppComponent
],
imports: [
BrowserModule,
BrowserAnimationsModule,
MatBadgeModule, MatButtonModule, MatIconModule,
FormsModule,
ReactiveFormsModule
],
providers: [],
bootstrap: [AppComponent]
})
export class AppModule { }
Following is the content of the modified HTML host file app.component.html.
<p><span matBadge = "4" matBadgeOverlap = "false">Mail</span></p>
<p>
<button mat-raised-button color = "primary"
matBadge = "8" matBadgePosition = "before" matBadgeColor = "accent">
Action
</button>
</p>
<p><mat-icon matBadge = "15" matBadgeColor = "warn">home</mat-icon></p>
