Question

I need to close server after getting callback from /auth/github/callback
url. With usual HTTP API closing
server is currently supporting with server.close([callback])
API function, but with node-express server i’m getting TypeError: Object function app(req, res){ app.handle(req, res); } has no method 'close'
error. And I don’t know how to find information to solve this problem.
How should I close express server?

NodeJS configuration notes:

$ node --version
v0.8.17
$ npm --version
1.2.0
$ npm view express version
3.0.6

Actual application code:

var app = express();

// configure Express
app.configure(function() {
    // … configuration
});

app.get(
    '/auth/github/callback',
    passport.authenticate('github', { failureRedirect: '/login' }),
    function(req, res) {
        res.redirect('/');

        setTimeout(function () {
            app.close();
            // TypeError: Object function app(req, res){ app.handle(req, res); } has no method 'close'
        }, 3000)
    }
);

app.listen('http://localhost:5000/');

Also, I have found ‘nodejs express close…’ but I don’t sure if I can use it with code I have: var app = express();.

app.listen() returns http.Server. You should invoke close() on that instance and not on app instance.

Ex.

app.get(
    '/auth/github/callback',
    passport.authenticate('github', { failureRedirect: '/login' }),
    function(req, res) {
        res.redirect('/');

        setTimeout(function () {
            server.close();
            // ^^^^^^^^^^^
        }, 3000)
    }
);

var server = app.listen('http://localhost:5000/');
// ^^^^^^^^^^

You can inspect sources: /node_modules/express/lib/application.js
