Question

I am following along with this article, which describes a good way to organize routes in express. I am encountering a problem though when i try to access the functions that i have exported from my main.js file. I get a 404 error when i curl “localhost/user/username”

//the routes section of my my app.js file
app.get('/', routes.index);
app.get('/user/:username', routes.getUser);

//my index.js file
require('./main');
require('./users');

exports.index = function(req, res) {
    res.render('index', {title: 'Express'});
};

//my main.js file

exports.getUser = function(req, res){
        console.log('this is getUser');
        res.end();
};

—-EDITED WITH MY SOLUTION—-

Here is the solution that I went with, maybe someone will find it useful. I’m also open to hearing suggestions about whether or not this is going to cause me any problems in the future.

//-------The routes in my app.js file now look like this.

require('./routes/index')(app);
require('./routes/main')(app);

//-------In index.js i now have this

module.exports = function(app) {
    app.get('/', function(req,res){
        res.render('index', {title: 'Express'});
    });
};

//-------My main.js now looks like this-------

module.exports = function(app){

    app.get('/user/:username', function(req, res){
            var crawlUser = require('../engine/crawlUser');
            var username = req.params.username;
            crawlUser(username);
            res.end();
    });

};
