example of backbone-style routing with Express

equivalent.js

app.get('/help', function(req, res){
  res.send('some help');
});

app.get('/search/:query/p:page', function(req, res){
  var query = req.params.query
    , page = req.params.page;
  res.send('search "' + query + '", page ' + (page || 1));
});

router.js

function Router(obj) {
  this.methods = obj;
  this.route(obj.routes);
}

Router.prototype.route = function(obj){
  var self = this
    , routes = Object.keys(obj);

  Object.keys(obj).forEach(function(route){
    var parts = route.split(' ')
      , method = parts.shift().toLowerCase()
      , path = parts.shift()
      , fn = self.methods[obj[route]];

    app[method]('/' + path, function(req, res, next){
      var args = req.route.keys.map(function(key){
        return req.params[key.name];
      });
      fn.apply(res, args);
    });
  });
};


Router.extend = function(obj){
  return new Router(obj);
};

usage.js

// GET /help
// GET /search/foobar
// GET /search/foobar/p2

var router = Router.extend({
  routes: {
      'GET help': 'help'
    , 'GET search/:query': 'search'
    , 'GET search/:query/p:page': 'search'
  },

  help: function(){
    this.send('some help');
  },

  search: function(query, page){
    this.send('search "' + query + '", page ' + (page || 1));
  }
});

this is a really quick mockup of how you could utilize higher level routing, since sometimes people seem to forget that you can build on basic routes, while of course still retaining the lower level flexibility app.get() etc

right on

Is this going to be included in express on in a separate module ?

@DarkSmith didn't plan on either but it could easily be an extension like express-resource

This is really cool.
