How to use push notification using service workers in Ionic 2?

I want to use push notification using service workers in my ionic 2 app. Any help would be appreciated how to do it ?

Hello Ionic Team,

Happy to see PWA support, but I think documentation is currently a problem. Actually, I am also working on similar push notification and have add a external push.js for the notification features.

Another thing I can’t directly add this as typescipt build give error and unable to call the functions in main.ts file.

Thanks
Gaurav

Have you integrated push for PWA??
