title: How do I hot reload a controller in Koa?
body: <p>When a request comes in, I want to reload the controller to improve debugging speed.</p>
  
  <p>When I make a change to a controller method I have to reload the whole server which take 4-5 seconds.</p>
  
  <p>I am also using <code>koa-mount</code> to configure different endpoints so the solution must be compatible with <code>koa-mount</code>.</p>
