Getting count of total messages in a subscription client that is taking messages from azure topics

I am using this code :

 var ServiceBusClient = require('azure-service-bus-client');
 var serviceBusClient = new ServiceBusClient(
 {
    serviceBusConnection: ""
  }
);

(function(){
   serviceBusClient.receiveSubscriptionMessage(topicName, subscriptionName, 
     function (err, message) {
       console.log("message body :", message);
    });

 })();

I am searching for a particular message body, for which I am thinking to iterate the above method - receiveSubscriptionMessage() but for this I need the count of total messages in a subscription client.

I am looking for node.js code, many places on internet they have given in JAVA or c# but for count I cannot find MessageCount. Any help will be fine.

Link to the libraray I am using is : https://www.npmjs.com/package/azure-service-bus-client

I know this is a late reply, but the library mentioned in the post is not maintained by Microsoft or Azure.

The latest version 7.0.0 of @azure/service-bus offers ServiceBusAdministrationClient that lets you manage the service-bus resources.

For the problem in this question, you can leverage the getSubscriptionRuntimeProperties method to get the count of messages in the subscription.

Here is an example on using ServiceBusAdministrationClient - administrationClient.ts

In case someone is running into issues with the older service-bus SDK for node and landed here, refer to the links below.

The total count is not possible to fetch, until and unless we have the command over the sender.

So, the other workaround that I was able to figure out was only after receiving and checking every message for the specific pattern/condition required.
