title: Angular 2: how to clean build?
body: <p>I'm using a development setup suggested <a href="https://angular.io/docs/ts/latest/guide/setup.html" rel="nofollow noreferrer">here</a>. At some point I have decided to delete a typescript file (say, 'myfile.ts'). My app was re-compiled in a blink of an eye, but myfile.js and myfile.js.map were left behind, although apparently they aren't needed any more. How does one "clean and build" Angular 2 apps?</p>
