Node.js Question

Stop node.js program from command line

I have a simple TCP server that listens on a port.

var net = require("net");

var server = net.createServer(function(socket) {


I start it with
node server.js
and then close it with Ctrl + Z on Mac. When I try to run it again with
node server.js
I get this error message:

throw e; // process.nextTick error, or 'error' event on first tick
Error: listen EADDRINUSE
at errnoException (net.js:670:11)
at Array.0 (net.js:771:26)
at EventEmitter._tickCallback (node.js:192:41)

Am I closing the program the wrong way? How can I prevent this from happening?


To end the program, you should be using Ctrl + C. If you do that, it sends SIGINT, which allows the program to end gracefully, unbinding from any ports it is listening on.
