title: Mysterious parameter -r in Nodemon
body: <p>I've been searching on how to reload env on the development environment while using <code>Nodemon</code>.</p>
  
  <p>The command that spread all over on the internet is <code>nodemon -r dotenv/config bin/www.js</code>, this is actually working, but look at the command, what is the <code>-r</code> thing? I'm out of curiosity.</p>
  
  <p>I've been searching on the official documentation with no luck. <a href="https://github.com/remy/nodemon/wiki" rel="nofollow noreferrer">https://github.com/remy/nodemon/wiki</a></p>
  
  <p>Anyone care to explain, thank you.</p>
