Connect / Restify middleware for CLS

Dirt-simple middleware for Connect and Restify handlers into a continuation-local storage context.

Example app.js:

var cls     = require('continuation-local-storage');
var express = require('express');
var clsify  = require('cls-middleware');
var route   = require('./route.js');
 
var ns = cls.createNamespace('namespace');
 
var app = express();
app.use(clsify(ns));
 
ns.set('whatever', 'a value');
 
app.get('/users', route);

with ./route.js:

var cls = require('continuation-local-storage');
 
module.exports = function (req, res, next) {
  // pulling from the namespace, and set up per request
  res.send({value : cls.getNameSpace('namespace').get('whatever')});
 
  next();
};
