title: Run script on change in nodemon
body: <p>Is it possible to run a script on change using nodemon?</p>
  
  <p>Is it possible to do something like this: <code>nodemon --watch src --exec yarn run my-script</code>?</p>
  
  <p>So, ideally I'd like to run a script only when there're changes in a <code>src</code> folder</p>
