Step 1: Install the Angular Material package:

You need to install and configure Angular Material in your Angular 17 project. The process is easy and straightforward.

Step 2: Import the necessary modules into your Angular app:

import { MatSnackBarModule } from '@angular/material/snack-bar';

Step 3: Create a service to manage the alert messages:

import { Injectable } from '@angular/core';
import { MatSnackBar } from '@angular/material/snack-bar';

@Injectable({
  providedIn: 'root'
})
export class AlertService {

  constructor(private snackBar: MatSnackBar) { }

  openSnackBar(message: string, action?: string) {
    this.snackBar.open(message, action, {
      duration: 3000,
    });
  }
}

Step 4: Inject the AlertService into your component:

import { Component, OnInit } from '@angular/core';
import { AlertService } from './alert.service';

@Component({
  selector: 'my-app',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent implements OnInit {

  constructor(private alertService: AlertService) { }

  ngOnInit() { }

  openSnackBar() {
    this.alertService.openSnackBar('This is an alert message.');
  }
}

Step 5: Add a button to your template and bind the click event to the openSnackBar() method:

<button mat-raised-button (click)="openSnackBar()">Open Snack Bar</button>

Step 6: Start your Angular app:

ng serve

In this detailed blog post, we have meticulously outlined the process of implementing an Angular Material alert message. While the example provided is foundational, it serves as a solid starting point that you can build upon and tailor to align precisely with your unique requirements.

Beyond the fundamental implementation, you have the flexibility to customize the alert message to suit your specific needs.
