Route improvements

We now have quite a few routes required in our Express server; let's clean this up. A common pattern in node.js is to include an index file that returns all files in its current directory. We will use require-directory to do this for us:

npm install require-directory –save

Let's create a new module ./lib/routes/index.js. with the following code:

var requireDirectory = require('require-directory');
module.exports = requireDirectory(module, __dirname, ignore);

Now, all routes in the ./lib/routes/ folder will be exposed under a single variable, routes:

  var express = require('express')
  , http = require('http')
  , config = require('../configuration')
  , db = require('../db')
  , routes = require('../routes')
  , notFound = require('../middleware/notFound')
  , id = require('../middleware/id')
  , app = express();

app.use(express.bodyParser());
app.set('port', config.get('express:port'));
app.use(express.logger({ immediate: true, format: 'dev' }));
app.param('id', id.validate...
