Angular Bootstrap Alerts

Angular Bootstrap alerts are a convenient way to display important and timely information to users. It can be used to notify users about successful operations, errors, warnings, or information requests. In Angular, we can use the ng-bootstrap package to create alerts with the Bootstrap styles.

Syntax

<ngb-alert [dismissible]="true|false" [type]="success|info|warning|danger" (close)="onClose()">
  Alert content here
</ngb-alert>

Example

  The operation was successful!
</ngb-alert>

Clicking on the close button will dismiss the alert.

The ngb-alert component is part of the ng-bootstrap package that provides Angular directives and components for Bootstrap. It accepts several parameters, such as:

• dismissible: a Boolean value that indicates whether the alert can be dismissed by the user or not.
• type: a string value that determines the alert type - success, info, warning, or danger.
• (close): a function that is executed when the alert is closed.

Use

Angular Bootstrap alerts are useful for displaying any kind of important information, such as:

• Success messages after a form submission
• Error messages when an operation fails
• Warnings when user input is invalid
• Informational messages for users
