Details

The Notification Service is implemented on top of the Angular Material Design snackbar. Use this service to show a notification message, and optionally get feedback from it.

import { NotificationService } from '@alfresco/adf-core';

export class MyComponent implements OnInit {

    constructor(private notificationService: NotificationService) {
    }

    ngOnInit() {
        this.notificationService
            .openSnackMessage('test', 200000)
            .afterDismissed()
            .subscribe(() => {
                console.log('The snack-bar was dismissed');
            });
    }
}

import { NotificationService } from '@alfresco/adf-core';

export class MyComponent implements OnInit {

    constructor(private notificationService: NotificationService) {
    }

    ngOnInit() {
        this.notificationService
            .openSnackMessageAction('Do you want to report this issue?', 'send', 200000)
            .afterDismissed()
            .subscribe(() => {
                console.log('The snack-bar was dismissed');
            });
    }
}

import { NotificationService } from '@alfresco/adf-core';
import { MatSnackBarConfig } from '@angular/material/snackbar';

export class MyComponent implements OnInit {

    snackBarConfig: MatSnackBarConfig = new MatSnackBarConfig();

    constructor(private notificationService: NotificationService) {
    }

    ngOnInit() {
        this.notificationService
            .openSnackMessageAction('Do you want to report this issue?', 'send', snackBarConfig)
            .afterDismissed()
            .subscribe(() => {
                console.log('The snack-bar was dismissed');
            });
    }
}

The default message duration is 5000 ms that is used only if you don't pass a custom duration in the parameters of openSnackMessageAction/openSnackMessage methods. You can also change the default 5000 ms adding the following configuration in the app.config.json:

    "notificationDefaultDuration" : "7000"

Notification types

info	To notify messages. It will be displayed with an info icon next to it.
warn	To notify warning messages. It will be displayed with a warning icon next to it.
error	To notify errors. It will be displayed with an error icon next to it.

If a message is prompt to duplicate an existing notification and you don't want to overload the notification history component with the same message use the recursive type. I.e. notifications coming from an API call that are triggered every time a component is initialized. It will be displayed with an info icon next to it.
