Data structure of the messages in MQTT javascript Client PAHO [message #1695770]

Hello All,

I am using the Eclipse Paho javascript client to communicate between my device and the broker.
So currently I am sending a string in the message.

message1 = new Paho.MQTT.Message("Hello");

Is there a way I can send the message in any other format like a json or Google protocol Buffer instead of string?

Thankyou

As long as you can provide a String or ArrayBuffer to the Message constructor, you will be fine.
In order to post a JSON document, that would e.g. be:

message1 = new Paho.MQTT.Message(JSON.stringify( { "first_name": "ankur", "last_name": "bhatia" } ));
