I was following the official guide to getting started with push notifications in the web browser. I didn't work very well for me.
In the console I get the token as 'null' even after granting the permissions for the notification.
How should I resolve this?

    storageBucket: "xcvg.appspot.com",
    messagingSenderId: "467764584564"
  };
  firebase.initializeApp(config);
const messaging = firebase.messaging();
    messaging.requestPermission()
            .then(function(){
                console.log("GRANTED");
                return messaging.getToken();
            })
            .then(function(token){
                console.log(token);
            })
            .catch(function(err){
                console.log('Error Occurred.')
            })
</script>

That's a very weird scenario to be in, I'm assuming that there are no errors in the console?

One thing to call out with your example, you only need 'firebase.js' OR 'firebase-app' and 'firebase-messaging.js', not all three. 'firebase.js' is a large javascript file that contains *everything* in the firebase SDK. firebase-app and firebase-messaging is the minimum needed if you just wanted firebase messaging.

Few questions for you:

1. Is you demo hosted anywhere I can view it?

2. What browser and browser version are you using?
