  2. Configure your keys:

pubnub = new PubNub({
  publishKey : "myPublishKey",
  subscribeKey : "mySubscribeKey",
  uuid: "myUniqueUUID"
})

Add event listeners

pubnub.addListener({
  message: function (m) {
    // handle messages
  },
  presence: function (p) {
    // handle presence  
  },
  signal: function (s) {
    // handle signals
  },
  objects: (objectEvent) => {
    // handle objects
  },
  messageAction: function (ma) {
    // handle message actions
  },
  file: function (event) {
    // handle files  
  },
  status: function (s) {
  // handle status  
  },
});

Publish/subscribe

var publishPayload = {
    channel : "hello_world",
    message: {
        title: "greeting",
        description: "This is my first message!"
    }
