title: Starting node with v8 profiler enabled from ng start
body: <p>When starting my application in development mode I see 50% of the CPU is used by <b>node</b> executable. I wanted to know if this is something related with my code or something related with how <b>node</b> works.</p>
  
  <p>I found a nice response to a similar question here:
  <a href="https://stackoverflow.com/questions/10167477/how-to-debug-node-js-causing-100-cpu-usage">how to debug node.js causing 100% cpu usage?</a></p>
  
  <p>But I cannot follow the indicated steps because I'm developing using angular, and angular is started by running <code>ng serve</code>.</p>
  
  <p>The documentation of <code>ng serve</code> is here: <a href="https://angular.io/cli/serve" rel="nofollow noreferrer">https://angular.io/cli/serve</a> but I can't see anything to send additional parameters to <b>node</b>. Even more, if I try to do <code>ng serve --prof</code> an error is generated.</p>
  
  <p>What else can I do in order to profile the execution of node.js?</p>
  
  <p>Thanks for your time</p>
