We've been writing services to access our on-premises databases through Azure Service Bus Relay for awhile now. That means that we've had to deploy them as WCF services. Our web site development is moving to node.js and I would like to begin deploying our API services on node as well. However, while the Azure NPM package has good support for queues/topics on Azure Service Bus, I can find no mention of the relaying capabilities. I've had a look at the code for the Azure SDK on github, but again, relay seems to be conspicuously absent.
Is it possible to use Azure Service Bus Relay with a node.js backend?
Now Azure support Node.js. You can find the infomration from here. This link is the samples for Node.js.
