title: How to use MongoDB with mean.io
body: <p>I am new to server side javascipt. I have started with mean.io. I gained some understanding of nodejs, express, mongodb last few days. I have my mean.io app but I don't know what's the right way to connect to mongodb and query it from my js files.<br>
  Is there a guide/blog which can help me work with mongodb from my server side javascript files?<br>
  All I want is to store some data mongodb and fetch that at some later point.</p>
