title: How to trigger `exports.handler` in atom editor
body: <p>This may be extremely silly. </p>
  
  <p>I was using aws lambda functions for a while, and they usually start with <code>exports.handler = (event, context, callback)</code>. AWS already has a test button where you can load in JSON and it tests it by providing JSON as an input to <code>exports.handler</code>, ad then from within the handler, formatting is done on the inputs, therse a bunch of <code>console.logs()</code> that are printed and so on.</p>
  
  <p>I recently moved to atom editor, and moved all my code over from lambda. I am using Atom Runner to run my JS code.. however I realised when I run it, all I get is: <code>Exited with code=0 in 0.745 seconds</code>. Basically it isn't running at all. </p>
  
  <p>How do I trigger <code>exports.handler</code> in Atom Editor? do I have to store JSON in a new file and call it in some way?</p>
