How do you debug an Angular 6 library : <p>I'm writing an Angular 6 Library and cannot figure out how to step into the typescript.</p>

<p>I generated the app using: <code>ng new mylibapp</code></p>

<p>I then added the library using: <code>ng g library @abc/cool-lib -p abc</code></p>

<p>when I perform: <code>ng build @abc/cool-lib</code></p>

<p>it generates the code in the <code>mylibapp/dist/abc/cool-lib</code> folder</p>

<p>How can I now debug this code and set breakpoints in the ts file located at <code>mylibapp/projects/abc/cool-lib/src/lib</code></p>
