Stop node.js program from command line

Question

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

var net = require(\"net\");

var server = net.createServer(function(socket) {
    socket.end(\"Hello!\\n\"         


        

Answer 1

My use case: on MacOS, run/rerun multiple node servers on different ports from a script

run: "cd $PATH1 && node server1.js & cd $PATH2 && node server2.js & ..."

stop1: "kill -9 $(lsof -nP -i4TCP:$PORT1 | grep LISTEN | awk '{print $2}')"

stop2, stop3...

rerun: "stop1 & stop2 & ... & stopN ; run
