The next phase of usefullness is turning the light off. In this next version, we keep track of whether the light is on or off, and toggle it upon receiving a TCP connection.

var b = require('bonescript');
var net = require('net');
var LEDS = [
var state = b.LOW;
LEDS.forEach(function (LED) {
  b.pinMode(LED, b.OUTPUT);
  b.digitalWrite(LED, state);
var server = net.createServer(function(connection) {
  console.log('Received connection');
  state = Number(!Boolean(state));
  LEDS.forEach(function (LED) {
    b.digitalWrite(LED, state);
server.listen(9999, function () {
  console.log('Ready for commands');

This works, but it’s fairly crude. What would be better is defined protocol beyond just listening for connections.
