title: Is bundle necessary in a pure-backend NodeJS app?
body: <p>I'm quite new in this overwhelmingly huge world of js-stack-tools and recently I've been following some tutorials about bundlers, which seem to include almost always the frontend facet.</p>
  
  <p>But in a simple app with only server-side participation (like a single service app in a microservices architecture) is it necessary to bundle the app? what are the pros/cons of doing it? </p>
  
  <p>If <code>pros &gt; cons</code> would be a good practice to use Jest's snapshots to check the <code>bundle.js</code> file? </p>
  
  <p>My apologizes if the question turns to be a bit ambiguous but I'm struggling trying to fit all these new concepts in my head.</p>
