title: How to use bootstrap 4 in angular 2?
body: <p>I'm building an angular 2 app written in typescript. It would use the bootstrap 4 framework in combination with some custom theming, is this possible?</p>
  
  <p>The "ng2-bootstrap" npm package is not working as it doesn't allow me to use the bootstrap css classes, instead it provides custom components. (<a href="http://github.com/valor-software/ng2-bootstrap" rel="noreferrer">http://github.com/valor-software/ng2-bootstrap</a>)</p>
  
  <p>In my angular 2 project I'm using sass, would it be possible to build bootstrap 4 from source as it is also using sass for styling?</p>
