Really ugly quick hack at route extending a componentized express app.

app.routes.js

var path = require('path');

module.exports = function(app) {

  app.get('/dashboard', app.user.loggedIn, function(req, res) {
    return res.render(path.join(__dirname, 'home/dashboard'), {
      user: req.session.user
    });
  });

  app.get('/'), function(req, res) {
    return res.render(path.join(app.viewsDir, 'home/index'));
  });

  app.get('/blog', app.routes.include('blog.routes');
};

blog.routes.js

var path = require('path');

module.exports = function(app) {
  var routes = app.routes;

  routes('/*', function(req, res) {
    return res.render(path.join(app.viewsDir, 'blog/index'));
  });

  app.get('/:slug'), function(req, res) {
    return res.render(path.join(app.viewsDir, 'home/:slug'));
  });

  // more routes

};
