How to stop a node.js server without killing the process?

Question

Say a server is created like:

var net = require('net');  var server = net.createServer(); server.listen(32323, '127.0.0.1');  server.close(); // gives a "not running" error if there is IP in the listen statement 

is there a way to stop it from node.js, e.g. without ending/killing the whole process?

Also, here's a more complicated example that doesn't stop regardless of the IP the server is bound to:

var net = require('net');  var server = net.createServer(function(socket) {     socket.on('data', console.log);     server.close(); });  server.listen(32323);  var socket = net.createConnection(32323); socket.write('hi'); 

Answer 1

server.close

Do not call close before the "listening" event fires.

Either add a callback to listen or add an event manually

server.listen(port, host, function () { server.close(); }); // OR server.on("listening", function () { server.close(); }); server.listen(port, host);  var net = require('net');  var server = net.createServer(function(socket) {     socket.on('data', console.log);     server.close(); });  server.listen(32323);  var socket = net.createConnection(32323); // call end to make sure the socket closes socket.end('hi');
