Is it possible to publish a WCF RESTful web service with Node JS? If yes then please point me to tutorial/article on this topic.
I came to know about wcf.js library but I think it only supports SOAP services.
wcf.js is a library that allows node code to call WCF services. WCF is a framework for managed code, so you can't really use node.js to build WCF services (you can use something like edge.js to call, from node.js, a DLL in C# that serves a WCF service, but the whole code would be in .NET anyway). There are many frameworks to build RESTful services with node.js, such as the ones you can find at Node.js REST framework?, and WCF isn't one of them.
