I'm developing a Ruby app that communicate with Node.JS app and I want to know if there is a way to get the port used by the Node's app in my Ruby app.
If not, can you force to run on a choosen port, without changing the code in the Node's app ?
I have found this, but it is in JS.
Cheers !
EDIT: This is possible with -p port
You can use environment variable to provide the port number to application. Or give it as a command line parameter.
