FCM using HTTP/2 client
Documentation and use of APIs is exactly same as https://www.npmjs.com/package/fcm-node. The package uses HTTP/2 client for posting payload.
Sample Code
'use strict' var koa = ; var app = ; var FCM = ; var fcm = API_KEY;//same that was used in gcm app;app;
Now just open localhost:8080 in the browser
