title: Put breakpoint on node.js file
body: <p>Hi I have a standalone script which should be run on commandline (not trigger by API request)</p>
  
  <p>I can run this script this way <code>node db.js</code></p>
  
  <p>However, could I be able to put any breakpoint on this kind of script.</p>
  
  <p>And stop at the breakpoint when debugging?</p>
  
  <p>I can not imagine we can only use console.log to debug.</p>
  
  <pre><code>var mongoose = require('./db');
  fs= require('fs');
  var AppCtrl = require('../handlers/handlerModule.js');
  
  AppCtrl.joinJSONFiles("DeltaAirlines",function (err, data) {
     data.forEach()
         ....
  })
  </code></pre>
