There are many tutorials showing how to do that. I would recommend first you understand how HTTP protocol works (The message structure : https://www.w3.org/Protocols/rfc2616/rfc2616-sec4.html ). Then go dive into node and exchange data through requests and responses. I'd recommend body-parser to arrange the data format between the two sides. Also read the express documentation. Hope it helps.
