portscanner
A port scanner for node applications.
This will work within your application as an api. I found that I needed something to tell me about the first available port so that I could use it when creating test servers. Instead of write "yet another port scanner" that was specific to my testing code, I figured I'd try to make it a bit more robust. Time will tell whether this has been successful or not. Either way, it should be useful to me and hopefully it can be to you as well.
API
Coming soon.
