Configuration (apps)

To make your process compatible with Supervizer, you must follow this code example to retrieve host and port parameters :

var host = process.argv[2] || '';
var port = process.argv[3] || '5000';

For example, if you use expressjs framework :

var express = require('express');
var server = express();

server.use(express.static(__dirname + '/public'));

server.get('/', function(req, res) {      
    res.end('Hello word!');

server.get('*', function(req, res) {
      res.send('Not Found!', 404);

server.use(function(err, req, res, next) {      
      res.send(500, 'Something broke!');

var host = process.argv[2] || '';
var port = process.argv[3] || '5000';

console.log('Listening on port ' + port);
