How to capture the screen of UWP web app

Question

I want to take the screenshot of app running window in UWP javascript version. As I got RenderTargetBitmap there for doing same but only available for C# version of UWP.

I want to do the same thing in UWP javascript app.

Please let me know could it possibly be done in UWP javascript app and HOW?

Any help would be highly appreciated in advance.

Thanks

You might combine C# with JS, but I doubt you can do it with pure JS. — Federico Navarrete, Aug 07 '18 at 06:42
Yes, I am only dealing with pure javascript. Is it possible to build C# with javascript and how to communicate with between them? Please, would you share some links that support? — mani gupta, Aug 07 '18 at 06:45

Yes, I used HTML2Canvas before but it does not capture video frame (screenshot). always black screen captured — mani gupta, Aug 07 '18 at 07:35
Have you tried [html-screen-capture-js](https://www.npmjs.com/package/html-screen-capture-js) package? — CoCaIceDew, Aug 08 '18 at 02:57

We needed to get a screenshot of a web page using only javascript (no browser extensions, or user interaction). We've tried using html2canvas, but it seems like it can only handle a VERY basic UI. So, I wrote a small javascript library (html-screen-capture-js) for that purpose. Feel free to try it out.
