Push notification in ionic2

How can i do push notification in ionic2. can some one help?

Yes, Why not have you used parse push notification. check https://www.parse.com/?

or create your own push server ;). i do not like providers like parse, pushwoosh or BaaS like firebase. Because of their pricing policy. And i am from germany… i we need to give our local customers the trust to handle there data save. So we need (in a best scenario) providers directly in germany. But i have to say… germany is faaaaaar behind the actual state of the art in the topic IT or webtechnologies.

You can use SingleR http://www.asp.net/signalr if you are from .Net background to design push notification.
