Notification
Notifications provide a way to display and communicate information related to user actions within a page's content.
Overview
Notifications are used to display short messages that provide context in close promixity to a piece of content. They're often used to provide feedback or to notify users about an action they performed within a page. Notifications should not be used to display app-level alerts. Instead, use the Toast component.
Default Notification
Usage
Within a standalone component
To use notification in a standalone component, import DAFF_NOTIFICATION_COMPONENTS directly into your custom component:
@Component({
selector: 'custom-component',
templateUrl: './custom-component.component.html',
standalone: true,
imports: [
DAFF_NOTIFICATION_COMPONENTS,
],
})
export class CustomComponent {}
Within a module (deprecated)
To use notification in a module, import DaffNotificationModule into your custom module:
import { NgModule } from '@angular/core';
import { DaffNotificationModule } from '@daffodil/design/notification';
@NgModule({
declarations: [
CustomComponent,
],
exports: [
CustomComponent,
],
imports: [
DaffNotificationModule,
],
})
export class CustomComponentModule { }
This method is deprecated. It's recommended to update all custom components to standalone.
Supported Content Types
Icon
An icon can be used to give a user a brief overview of what the nofication is about. It can be added before the title and subtitle by using the daffPrefix selector.
Title
Title gives a quick overview of what the notification is about. It can be added by using the daffNotificationTitle selector.
Subtitle
Subtitle provides additional details about the notification that should be limited to one or two sentences. It can be added by using the daffNotificationSubtitle selector.

The status color of a notification can be updated by using the status property.

Notification with statuses
Orientation
Orientation dictates how a notification's content is stacked — vertical or horizontal. Notifications are oriented vertically by default. The orientation of a notification can be defined or updated by using the orientation property.
Dismissing a notification
Notifications are not dismissible by default. They typically persist on the page until a user takes action that resolves the notification.
The close button is hidden by default but can be visible by setting the dismissible property to true. It should remain hidden if a notification has critical information for a user to read or interact with.
Accessibility
Notifications with a critical or warn status have a role="alert" so that it can be announced by assistive technologies. See (live region roles)[https://developer.mozilla.org/en-US/docs/Web/Accessibility/ARIA/Roles#4._live_region_roles] for more information. All other notifications have a role="status". Notifications have a tabindex="0" so users can discover them while tabbing through a page.
