I'll revert this line.

EDIT: Just saw #588

checkPort();

function checkPort() {
tcpPortUsed
.check(port, 'localhost')
.then(function(inUse) {
if (inUse) {
console.error(chalk.red('Port ' + port + ' is in use'));
// Try again but with port + 1
port += 1;
checkPort();
// process.exit(1);

No, just the line you commented out. There's no need to leave it in

const server = require('./server/server.js');
server(port);
