A simple example using the Node.js module for Open311 in Baltimore.

var util = require('util');
var Open311 = require('open311').Open311;

var options = {

        'service_path': '/open311/v2/',
        'jurisdiction_id': 'baltimorecity.gov'
        };

var report = new Open311(options);

report.getServiceList('json', function(error, data) {
	if(error) {
		util.puts('WARNING: ' + data);
	}
	else {
		var services = JSON.parse(data);
		for(var i = 0; i < services.length; i++) {
	        util.puts('Service Name: ' + services[i].service_name);
	        util.puts('Service Code: ' + services[i].service_code);
	        util.puts('------');
