Question

I would like to use http.Server.connections in my express 3 route?
Is there no way to get it anymore?

Should I just
app.set(‘server’, server);

express.createServer() is deprecated and express applications no longer inherit from http.Server

var app = express(),
server = http.createServer(app);
server.listen(8080);
...
module.exports = function (app) {

    app.get('/connections', function (req, res) {
        res.send({
            connections: app.connections 
            // app != http.Server in express 3
        });
    });

};

Instead of app.connections you need to send server.connections, since you’ve used:

server = http.createServer(app);

So your code becomes:

app.get('/connections', function (req, res) {
    res.send({
        connections: server.connections 
    });
});
