Angular - Mat spinner

To use the Angular Material spinner (mat-spinner), follow these steps:

Step-by-Step Guide

  1. Install Angular Material: If you haven't already installed Angular Material, do so with the following command:

    ng add @angular/material

  2. Import MatProgressSpinnerModule: In your module file, import MatProgressSpinnerModule.

    import { MatProgressSpinnerModule } from '@angular/material/progress-spinner'; @NgModule({ imports: [ MatProgressSpinnerModule, // other imports ], }) export class AppModule {}

  3. Using the Spinner in Your Component: You can use the mat-spinner in your component's HTML.

Example Component TypeScript

import { Component } from '@angular/core'; @Component({ selector: 'app-your-component', templateUrl: './your-component.component.html', }) export class YourComponent { isLoading = true; // Simulate a data loading process loadData() { setTimeout(() => { this.isLoading = false; // Stop loading after 3 seconds }, 3000); } ngOnInit() { this.loadData(); } }

Example Component HTML

<!-- your-component.component.html --> <div *ngIf="isLoading" class="spinner-container"> <mat-spinner></mat-spinner> </div> <div *ngIf="!isLoading"> <p>Data loaded successfully!</p> <!-- Your content goes here --> </div>
  1. Styling the Spinner: You may want to center the spinner or apply custom styles.
/* your-component.component.css */ .spinner-container { display: flex; align-items: center; justify-content: center; height: 100vh; /* Full viewport height */ }

Customization

  • Size: You can set the spinner size using the diameter attribute.
<mat-spinner diameter="100"></mat-spinner>
  • Color: You can customize the spinner color using CSS or Angular Material's theme.
<mat-spinner color="primary"></mat-spinner>

Summary

  • Use mat-spinner to indicate loading states in your application.
  • Control the spinner's visibility using a boolean flag (e.g., isLoading).
  • Customize size and color to match your design.

This setup will help you effectively use the spinner in your Angular application!
