It's official, CodeTunnel.com is now a Node.js application! I had to do quite a bit of learning in order to finish the application but it was well worth it. My blog is the first Node application that I've ever written. When I learn a new programming language or framework I usually develop something for myself before I ever use the tool to develop something for a client. This allows me to deal with the learning curve on my own time without offloading that extra time onto an invoice. I like to make sure that I understand the basics as well as I can before I adopt a new tool.
If you're interested in looking at the code, the new Code Tunnel can be found on Github.
