title: Debugging PDFTron's WebViewer-UI in my Angular app
body: <p>I'm using PDFTron's WebViewer with customised WebViewer-UI for my Angular app.</p>
  <p>However, by re-building and re-copying build package to my Angular application is just wasting time when I re-build WebViewer-UI alot, and it also cannot debug WebViewer-UI from my app which I need to view WebViewer-UI interacting with non-permanent/temporary custom data from outside of WebViewer.</p>
  <p>I have tried setting lib Path and uiPath but that didn't load the debugging React app(indeed).</p>
  <p>I have tried the WVS but that also doesn't support debugging WebViewer-UI.
  I also see on PDFTron doc site that we can build custom server without the use of WVS but there is no guide in there.</p>
  <p>Have anyone achieved the similar real-time debugging WebViewer-UI from your app or this need cannot be achieved?</p>
