title: Start script after ng serve is up
body: <p>I have written a script that takes screenshots of my angular application. The Problem is the script only works if i start ng serve manually before my script. My question is can i tell ng serve to start a script if the development server is up and running. I tried <code>ng serve  &amp;&amp; node screenshot-generation.js</code> but the screenshot-generation script is not excuted because ng serve is not finished. </p>
  
  <p>Thank you for your help.</p>
