Route callbacks not executing but middleware is - node.js

Question

So this project was working fine before today, but after a bit of a nooby mistake with git I broke my project, and was unable to recover the commit. After spending some time getting everything fixed, my routes are now broken. My issue is that when calling my API routes now the server hangs for exactly 1 minute, then times out and logs a 404 on the server.
To give some background I'm using this boilerplate. In my debugging process I basically put console.logs everywhere I possibly could, and it looks like all my initialization middleware for express and passport are working fine, and my code is getting to where the routes are defined with no errors.
Middleware with app.use works and all checks out when a request is made, and all console.logs I've put there show fine. The console.logs only stop appearing in the final route definition like in this example:
app.get('/route', function(req, res, next) {
console.log('this never shows');
next();
}, function(req, res, next) {
console.log('this never shows');
})
My actual routes do have a res.send(), this is just an example to show you. All the console.logs I put in the middleware before this route show when the request is made, so it is hanging somewhere in app here.
It's a rather large project, so if you want specific code examples just ask and I'll post it. But I was able to recover all the important files that I had saved somewhere else and I'm pretty sure all my code is back to how it was before now.

Here is my file with express middleware definitions:
config/express.js
/**
* Module dependencies.
*/
var express = require('express');
var MongoStore = require('connect-mongo')(express);
var flash = require('connect-flash');
var helpers = require('view-helpers');

var session = require('express-session');
module.exports = function (app, config, passport) {
app.set('showStackError', true);
// should be placed before express.static
app.use(express.compress({
filter: function (req, res) {
return /json|text|javascript|css/.test(res.getHeader('Content-Type'));
},
level: 9
}));
app.use(express.favicon());
app.use(express.static(config.root + '/public'));
app.use('/uploads', express.static(config.root + '/uploads'));
var allowCrossDomain = function(req, res, next) {
res.header('Access-Control-Allow-Origin', '*');
res.header('Access-Control-Allow-Methods', 'GET,PUT,POST,DELETE');
res.header("Access-Control-Allow-Headers", "Access-Control-Allow-Methods, Access-Control-Allow-Headers, Access-Control-Allow-Origin, Origin, Accept, X-Requested-With, Content-Type, Access-Control-Request-Method, Access-Control-Request-Headers");
// intercept OPTIONS method
if ('OPTIONS' == req.method) {
res.status(204).end();
}
else {
next();
}
};
app.use(allowCrossDomain);
// don't use logger for test env
if (process.env.NODE_ENV !== 'test') {
app.use(express.logger('dev'));
}
// set views path, template engine and default layout
app.engine('html', swig.renderFile);
app.set('view engine', 'html');
app.set('views', config.root + '/app/views');
app.set('view cache', process.env.NODE_ENV !== 'development');
app.configure(function () {
// dynamic helpers
// app.use(function(req,res,next){
// req.locals.session = "eeeeeeee";
// next();
// });
// cookieParser should be above session
app.use(express.cookieParser());
// bodyParser should be above methodOverride
app.use(express.bodyParser());
app.use(express.methodOverride());
// express/mongo session storage
app.use(function(req, res, next) {
if(!req.cookies['_ga']) {
next();
}
else {
session({
secret: 'secrettexthere',
saveUninitialized: true,
resave: true,
store: new MongoStore({
url: 'mongodb://localhost/traderdb',
db: 'traderdb',
collection: 'sessions',
auto_reconnect: true
})
})(req, res, next);
}
});
// connect flash for flash messages
app.use(flash());
app.use(function (req, res, next) {
res.locals.session = req.session;
res.locals.req = req;
next();
});
app.use(function(req, res, next) {
if(!req.cookies['_ga']) {
next();
}
else {
passport.initialize()(req, res, next);
}
});
//app.use(helpers('app name'));
//
// use passport session
app.use(function(req, res, next) {
if(!req.cookies['_ga']) {
next();
}
else {
passport.session()(req, res, next);
}
});
// routes should be at the last
app.use(app.router);
// assume "not found" in the error msgs
// is a 404. this is somewhat silly, but
// valid, you can do whatever you like, set
// properties, use instanceof etc.
app.use(function(err, req, res, next) {
// treat as 404
if (~err.message.indexOf('not found')) return next();
// log it
console.error(err.stack);
// error page
res.status(500).render('500', { error: err.stack });
});
// assume 404 since no middleware responded
app.use(function(req, res, next) {
res.status(404).render('404', { url: req.originalUrl, error: 'Not found' })
});
})
}
I also have another file with passport route definitions if you'd like to see that too, but all that is tested and works okay too.

Answer 1

If app.use works, my guess would be your protocol, is the app.get correct? You issue is otherwise located somewhere else in your code base as your sample runs fine as a single route express app.

Answer 2

It sounds like one of three things:
Somewhere in your middleware chain, you are not calling next() to allow it to advance to the next level of handlers and thus the request just eventually times out waiting for that middleware to finish (this seems to match the symptoms you describe).
Somehow, your app.get() doesn't actually match the route you expect it to or is not specified correctly.
You're using a router, but have not configured it correctly.
But, because you don't get an immediate 404, but rather it times out, it is probably option #1 above.
