Connect Beacon with Angular Web Application

I want to develop a Progressive web application in angularJs and in that, I want to push notifications to the users using Estimote Beacons.
Idea is to send discount information using push notification to users by using beacons.
Can anyone give me any quick start idea? How Can I start that…
I tried to search but unable to find any web application solution for that. I have 3 Estimote beacons devices.
