I had a lot of issues trying to get continuation-local-storage (cls) working on a hapi.js app with pm2 in cluster_mode. Long story short, my mistake was wrapping cls around my server.start() when I should have been running it in a request handler. Here is the code you should use to get all this working:

var cls = require('continuation-local-storage');
var ns = cls.createNamespace('mySession');

var Hapi = require('hapi');
var server = new Hapi.Server();
server.connection({ port: 80 });

  app.all('*', function (req, res, next) {

    res.header("Access-Control-Allow-Origin", req.headers.origin);
    res.header("Access-Control-Allow-Credentials", true);
    res.header('Access-Control-Allow-Methods', 'GET,PUT,POST,DELETE,OPTIONS');
    res.header("Access-Control-Allow-Headers", "X-Requested-With, Content-Type, Authorization, Content-Length");

    if (req.method == 'OPTIONS') {
      return res.send(200);
    }

MongoDB provides a Javascript shell. But Javascript is no fun without underscore.js 

Turned out its straight forward to use underscore.js while scripting mongodb.

Here are the steps.

1) Use underscore to write your db script file (say my_commands.js)

       E.g: _.each(db.dbname.find().toArray(), function(itm) { ... })
