I'm trying to integrate OneSignal into my Angular 2 app to receive push notifications. First I did a HelloWorld app using plain old HTML and it works beautifully. So I tried to include it into my Angular app, but users are not getting created/registered, and hence are not subscribed to receive any notifications.
Code excerpts:

<script>
var OneSignal = window.OneSignal || [];
console.log("Init OneSignal");
OneSignal.push(["init", {
appId: "xxx-xxx-xxx-xxx-xxx",
autoRegister: false,
allowLocalhostAsSecureOrigin: true,
notifyButton: {
enable: true
}
}]);
console.log('OneSignal Initialized');
OneSignal.push(function () {
console.log('Registered For Push');
OneSignal.getUserId().then(function (userId) {
console.log("User ID is", userId);
});
});

The userId is always null.

I'm afraid I presented another case of skimming the docs instead of actually reading it.
So I moved the code around a bit and this is what ended up working for me.

app.component.ts
export class AppComponent implements OnInit {
.

.
.
ngOnInit() {
var OneSignal = window['OneSignal'] || [];
console.log("Init OneSignal");
OneSignal.push(["init", {
appId: "xxx-xxx-xxx-xxx",
autoRegister: false,
allowLocalhostAsSecureOrigin: true,
notifyButton: {
enable: false
}
}]);
console.log('OneSignal Initialized');
OneSignal.push(function () {
console.log('Register For Push');
OneSignal.push(["registerForPushNotifications"])
});
OneSignal.push(function () {
// Occurs when the user's subscription changes to a new value.
OneSignal.on('subscriptionChange', function (isSubscribed) {
console.log("The user's subscription state is now:", isSubscribed);
OneSignal.getUserId().then(function (userId) {
console.log("User ID is", userId);
});
});
});
}
.
.
.
}
Couple of things to note:
subscriptionChange and then get the userid subscriptionChange is also fired when user disables the notification manually from the browser.autoRegister: false, will not prompt the 'Allow'/'Deny' option. So we have to call registerForPushNotifications. One can use this to prompt for push notification on a button click or something.EDIT 2018
I've made a util class which I use across all my angular projects to reduce boilerplate code for onesignal.
