net.createConnection()

net.createConnection(options[, connectListener])

A factory function, which returns a new net.Socket and automatically connects with the supplied options.

The options are passed to both the net.Socket constructor and the socket.connect method.

The connectListener parameter will be added as a listener for the 'connect' event once.

Here is an example of a client of the previously described echo server:

const net = require('net');
const client = net.createConnection({port: 8124}, () => {
  //'connect' listener
  console.log('connected to server!');
  client.write('world!\r\n');
});
client.on('data', (data) => {
  console.log(data.toString());
  client.end();
});
client.on('end', () => {
  console.log('disconnected from server');
});

To connect on the socket /tmp/echo.sock the second line would just be changed to

const client = net.connect({path: '/tmp/echo.sock'});
