title: Angular2 -- Angular-CLI - Exclude folders from automatic build watchers
body: <blockquote>
    <p>angular-cli beta.16, using webpack. project created with the CLI</p>
  </blockquote>
  
  <p>Hi,</p>
  
  <p>This is my project structure :</p>
  
  <p><code>
  - server
     - server.js
  - src
     - app
         - compoents &amp; co
     - assets
     - index.html
  </code></p>
  
  <p>I'm using server.js for handling upload request coming from one of my angular component.
  The file is uploaded and I want to put it in the assets directory, so i can use it after in the app.</p>
  
  <p>The problem is when I do such work (uploading a file in the assets folders) that make my angular-cli to re build the entire app (because  it detect a change in my files), so the app is reloaded in the browser and i cannot use it.</p>
  
  <p>Is there a way to exclude somes folders (for me the 'assets' folder) for the "watch build" task of the CLI? so the CLI don't build the app again when i'm putting a new file into it?</p>
  
  <p>Thank you guys !</p>
