Write your First mesibo Enabled Application

Estimated reading time: 3 minutes

In this part, we will create a simple real-time app for Web (Javascript).


You MUST go through following prerequisites before you read further.

First Web (Javascript) App

Now let’s quickly start coding:

Add mesibo API for javascript in your code:

<script type="text/javascript" src="https://api.mesibo.com/mesibo.js"></script>

Now, initialize mesibo like shown below

var api = new Mesibo();
api.setListener(new MesiboListener());

Implement MesiboListener to receive messages and status in real-time.

function MesiboListener() {

MesiboListener.prototype.Mesibo_OnConnectionStatus = function(status, value) {
	console.log("TestNotify.prototype.Mesibo_OnConnectionStatus: "  + status);

MesiboListener.prototype.Mesibo_OnMessageStatus = function(m) {
	console.log("TestNotify.prototype.Mesibo_OnMessageStatus: from "  
			+ m.peer + " status: " + m.status);

MesiboListener.prototype.Mesibo_OnMessage = function(m, data) {
	console.log("TestNotify.prototype.Mesibo_OnMessage: from "  + m.peer);

That’s it - you are now ready to receive your first real-time message.

Testing your first application

  1. Compile and Run Application.
  2. Mesibo_onConnectionStatus should cycle through various status information. Finally, you should receive status=1 which indicates that your app is successfully connected to mesibo real-time server and ready to send and receive real-time messages.
  3. Since we do not have any other users right now, we will use mesibo console to send a test message. In later section, we will learn how to send messages from the app itself.
    • Go to Console ->Application->Users. You should see the user you have created.
    • Go to user details by clicking Edit button. Scroll down, you will see a section to Message User
    • Enter 1000 (or anything) in From field, check Create This User checkbox, type message and click on Send.
  4. You will instantly receive this message in your mobile app in Mesibo_onMessage listener.

Sending Messages

In previous section, we have used mesibo console to send a message. Now we will quickly learn how to send messages from app itself. To send messages, we will use sendMessage real-time API for which we will need destination user, message id and message itself.

Invoke following function anywhere from your code to send a text message. In later section, we will learn how to send rich messages.

function sendTextMessage(to, message) {
	var p = {};
       	p.peer = to;
	var id = parseInt(Math.random()*10000);
	api.sendMessage(p, id, message);

That’s it! Try it out by creating two instances of the app and send message to each other by using above function.
