title: How to prevent visual studio 2017 from build javascript?
body: <p>I upgraded today to VS2017, and I saw that every time I change something in my my web app project - the build build all my javascript again (I'm using webpack for client).
  It is cool, but it take a lot of time, so I'll be happy to configure it to stop building the javascript (and I'll build it myself just when it changed). </p>
