Alert notifications are an extremely common requirement in web applications for displaying status messages to the user e.g. error, success, warning and info alerts.

This tutorial shows how to implement a simple reusable alert notification module in Angular 9. The example has two pages, one with a single alert and the other with multiple alerts displayed in two separate sections. Styling is done with Bootstrap 4.4 CSS.

The example project code is available on GitHub at https://github.com/cornflourblue/angular-9-alert-notifications.
