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.
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>
Verify the result.
