I got no response from the Node.js Bloomberg API package (blpapi) - node.js

Question

I'm working on a Node.js project and I need to price some stocks with the Bloomberg API. I found out that there's an NPM package for this API, so I had it installed and started testing it according to https://github.com/bloomberg/blpapi-node but I'm getting no responses.
This is my code:
var blpapi = require('blpapi');
var bloombergPricing = function ()
{
var session = new blpapi.Session({ host: '127.0.0.1', port: 8194 });
session.on('SessionStarted', function(m) {
console.log('bonjou');
session.openService('//blp/mktdata', 1);
});
var securities = [
{ security: 'AAPL US Equity', correlation: 0, fields: ['LAST_TRADE'] },
{ security: 'GOOG US Equity', correlation: 1, fields: ['LAST_TRADE'] }
];
session.on('ServiceOpened', function(m) {
console.log(session);
if (m.correlations[0].value == service_id) {
console.log(session);
session.subscribe(securities);
}
});
session.on('MarketDataEvents', function(m) {
if (m.data.hasOwnProperty('LAST_TRADE')) {
console.log(securities[m.correlations[0].value].security,
'LAST_TRADE', m.data.LAST_TRADE);
}
});
}
Is this package still working? If not, how is it possible to call the Java Bloomberg API from Node.js?
Thank you very much.

I think you're missing a session.start(); at the end of the function. This will trigger off the connection.
edit to include code that works for me:
var blpapi = require('blpapi');
var bloombergPricing = function ()
{
var session = new blpapi.Session({ host: '127.0.0.1', port: 8194 });
session.on('SessionStarted', function(m) {
console.log('bonjou');
session.openService('//blp/mktdata', 1);
});
var securities = [
{ security: 'AAPL US Equity', correlation: 0, fields: ['LAST_TRADE'] },
{ security: 'GOOG US Equity', correlation: 1, fields: ['LAST_TRADE'] }
];
session.on('ServiceOpened', function(m) {
console.log(session);
if (m.correlations[0].value == 1) {
console.log(session);
session.subscribe(securities);
}
});
session.on('MarketDataEvents', function(m) {
if (m.data.hasOwnProperty('LAST_TRADE')) {
console.log(securities[m.correlations[0].value].security,
'LAST_TRADE', m.data.LAST_TRADE);
}
});
session.start();
}
bloombergPricing();
