app.use don't get fired

Question

I am trying to use a middleware on my aplication to check on all routes if the token is passed, at the moment i want to test it just with the /users route, so i did this on my app file:

var express = require('express');
var path = require('path');
var favicon = require('serve-favicon');
var logger = require('morgan');
var cookieParser = require('cookie-parser');
var bodyParser = require('body-parser');
var debug = require('debug')('express-sequelize');
var http = require('http');
var models = require('./models');
var jwt = require('./routes/jwt');
var app = express();


// uncomment after placing your favicon in /public
//app.use(favicon(path.join(__dirname, 'public', 'favicon.ico')));
app.use(logger('dev'));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: false }));
app.use(cookieParser());
app.use(express.static(path.join(__dirname, 'public')));

app.use('/',require('./routes/authentication'));

app.use('/users',jwt); // executa a verificacao do token em todas as rotas excepto o registo e login


// catch 404 and forward to error handler
app.use(function(req, res, next) {
  var err = new Error('Not Found');
  err.status = 404;
  next(err);
});

then in my jwt file i did this:

var express = require('express');
var User = require('../models').User;
var router = express.Router();
var jwt = require('jsonwebtoken');

// route middleware to verify a token
module.exports = function () {
    return function (req, res, next) {
        console.log("entered");
        // check header or url parameters or post parameters for token
        var token = req.body.token || req.query.token || req.headers['x-access-token'];
        // decode token
        if (token) {
            // verifies secret and checks exp
            jwt.verify(token, app.get('superSecret'), function (err, decoded) {
                if (err) {
                    return res.json({ success: false, message: 'Failed to authenticate token.' });
                } else {
                    // if everything is good, save to request for use in other routes
                    req.decoded = decoded;
                    next();
                }
            });
        } else {
            // if there is no token
            // return an error
            return res.status(403).send({
                success: false,
                message: 'No token provided.'
            });

        }
    }
};

my jwt file is inside the routes folder that is at same level as the app file, any sugestion? it doesn't hit the route

Your jwt file isn't set up correctly, change it to

var express = require('express');
var User = require('../models').User;
var router = express.Router();
var jwt = require('jsonwebtoken');

router.get('/', function(req, res, next) {
    console.log("entered");

    // check header or url parameters or post parameters for token
    var token = req.body.token || req.query.token || req.headers['x-access-token'];
    // decode token
    if (token) {
        // verifies secret and checks exp
        jwt.verify(token, app.get('superSecret'), function (err, decoded) {
            if (err) {
                return res.json({ success: false, message: 'Failed to authenticate token.' });
            } else {
                // if everything is good, save to request for use in other routes
                req.decoded = decoded;
                next();
            }
        });
    } else {
        // if there is no token
        // return an error
        return res.status(403).send({
            success: false,
            message: 'No token provided.'
        });

    }
})

module.exports = router;
