title: How to watch and reload ts-node when TypeScript files change
body: <p>I'm trying to run a dev server with TypeScript and an Angular application without transpiling ts files every time.</p>
  <p>What I found is that I <em>can</em> run <code>.ts</code> files with <code>ts-node</code> but I want also to watch <code>.ts</code> files and reload my app/server. An example of this is the command <code>gulp watch</code>.</p>
  <p>Thank you in advance!!</p>
