How to asynchronously service multiple QBWC clients with Node.js

Question

The idea is to implement a QBWC web service using Node.js which can serve multiple incoming requests in an asynchronous fashion. Currently I am looking into qbws which is a Node.js web service for QuickBooks Desktop Web Connector. Any ideas on how I can extend this to support an asynchronous architecture for the service methods?
Thanks in Advance!

Answer 1

The soap module supports asynchronous function calls which makes this easy to do. To use the same template as my other answer, here's how you'd do that:

var soap = require('soap');

var yourService = {
    QBWebConnectorSvc: {
        QBWebConnectorSvcSoap: {
            serverVersion: function (args, callback) {

                // serverVersion code here

                callback({
                    serverVersionResult: { string: retVal }
                });
            },
            clientVersion: function (args, callback) {

                //clientVersion code here

                callback({
                    clientVersionResult: { string: retVal }
                });
            },

            // and all other service functions required by QBWC

        }
    }
};

There are two differences:

1. Each method signature has an additional callback parameter
2. There is no return, that's handled by callback() instead.

I don't currently have a suitable environment to test this, but I created a client to imitate QuickBooks Web Connector and it worked fine. Converting the qbws methods to asynchronous allowed it to service multiple clients simultaneously (including one legitimate QBWC client).
