An Angular wrapper around the Notifications API
If you arn't familiar with push notifications you can read more about them on the Mozilla developer network.
To install this library, run:
$ npm install ng-push --saveImport the PushNotificationsModule in to your AppModule:
@NgModule({
imports: [PushNotificationsModule],
declarations: [AppComponent],
bootstrap: [AppComponent]
})
export class AppModule { }Now import the PushNotificationsService where you want to use it:
constructor( private _pushNotifications: PushNotificationsService ) {}To request permission from the user to display push notifications call the requestPermission() method on the PushNotificationsService.
You can create a notification calling the create(title: string, options: PushNotification) method, like this:
this._pushNotifications.create('Test', {body: 'something'}).subscribe(
res => console.log(res),
err => console.log(err)
)The create() method returns an observable that emits the notification and the event when ever a show, click, close or error event occurs.
If you don't have permission to display the notification then the Permission not granted error will be thrown.
The following are options that can be passed to the options parameter:
interface PushNotification {
body?: string
icon?: string
tag?: string
renotify?: boolean
silent?: boolean
sound?: string
noscreen?: boolean
sticky?: boolean
dir?: 'auto' | 'ltr' | 'rtl'
lang?: string
vibrate?: number[]
}Options correspond to the Notification interface of the Notification API: Mozilla developer network.
this._pushNotifications.create(
'Example One',
{body: 'Just an example'}
)
.subscribe(res => {
if (res.event.type === 'click') {
// You can do anything else here
res.notification.close();
}
}
)Thank you @anode7 for submitting this example
import {Component, Inject, PLATFORM_ID, Injector} from '@angular/core';
import {isPlatformBrowser} from '@angular/common';
@Component({})
export class ExampleComponent {
private _push:PushNotificationsService;
constructor(
@Inject(PLATFORM_ID) platformId: string,
private injector: Injector,
) {
if (isPlatformBrowser(platformId)) {
//inject service only on browser platform
this._push = this.injector.get(PushNotificationsService);
}
}
}A standard method used in Universal is creating a mock service which is injected in the ServerModule. A good example can be found here.
