World's smallest useful Node.js Express web controller library you can do. Say no to frameworks!

controller.js

var inherit = require("descend")

var Controller = module.exports = function(req, res, next) {
  this.req = req
  this.res = res
  this.next = next
}

Controller.inherit = function() {
  var heir = inherit.apply(this, arguments)
  _.extend(heir, this)
  return heir
}

Controller.action = function(name) {
  var self = this

  return function(req, res, next) {
    new self(req, res, next)[name](req, res, next)
  }
}

Use it as such:

var FooController = module.exports = Controller.inherit()

FooController.route = function(app) {
  app.get("/foo", this.action("index")
}

FooController.prototype.index = function(req, res, next) {
  res.send("Hello!")
}

Then pass Express.js's app to FooController.route and you're good to go. Again, steer clear of frameworks for frameworks' sake!
