title: Web Worker in Angular Library
body: <p>I'm developing an angular library  that perform strong computation operations. So I was interested in implementing the web worker in order to have a better user experience and let the complex operations run on the background. </p>
  
  <p>My problem is that when I run the command <code>ng g web-worker</code> with Angular CLI 8, the output is <code>Web Worker requires a project type of "application".</code>
  Does anyone has suggestion on how to proceed for implementing web worker in my library?</p>
