Integrating OneSignal with Angular
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.
index.html
<html>
<head>
<meta charset="utf-8">
<title>My Angular App</title>
<base href="/">
<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="icon" type="image/x-icon" href="favicon.ico">
<head>
<link rel="manifest" href="/manifest.json">
<script src="https://cdn.onesignal.com/sdks/OneSignalSDK.js" async='async'></script>
<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/animate.css/3.5.2/animate.min.css">
</head>
</head>
<body>
<app-root>
<div class="wrap">
<div class="loading outer">
<div class="loading inner"></div>
</div>
</div>
</app-root>
</body>
</html>
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:
- Listen to the
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 callregisterForPushNotifications
. 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.

The simplest solution would be to just put the script provided by One Signal into your index.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8" />
<meta content="text/html; charset=utf-8" http-equiv="Content-Type" />
<meta
content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=no"
name="viewport"
/>
...
...
<link rel="manifest" href="/manifest.json" />
<script src="https://cdn.onesignal.com/sdks/OneSignalSDK.js" async=""></script>
<script>
var OneSignal = window.OneSignal || [];
OneSignal.push(function() {
OneSignal.init({
appId: 'xxx-xxxx-xxxxx',
});
});
</script>
...
Add the following into angular.json
...
"architect": {
"build": {
"builder": "ngx-build-plus:build",
"options": {
"outputPath": "dist/browser",
"index": "src/index.html",
"main": "src/main.ts",
"polyfills": "src/polyfills.ts",
"tsConfig": "src/tsconfig.app.json",
"assets": [
"src/favicon.ico",
"src/favicon.png",
"src/manifest.json", <-- this
"src/OneSignalSDKUpdaterWorker.js", <-- this
"src/OneSignalSDKWorker.js", <-- and finally this one
"src/assets"
],
"styles": [
"src/styles.scss"
],
"stylePreprocessorOptions": {
"includePaths": ["src/assets/sass"]
},
"scripts": []
},
...
And place the manifest and the 2 *.js file into /src/*
That's it. You will need to publish it to your server and not your localhost:4200. I got it to work on mine using this method. Hope that helps
