How can I add Html, Js functionality.

[allcpu]

Good day Sir,
I want to use your project for liveness detection.
But I am a js developer.
I know with the help of your project webrtc is used but I want that to happen in Html client not directly as I want other gui on same page.
I will detect liveness with your project then I want to do face recognition with face-api.js library.
For that The webrtc should be implemented in client html.
Please help.
My aim : detect liveness -> face recognition -> Mark Attendance -> change js values.
The last three are done but how to use js webrtc to feed the client stream to your program.
Thanks in advance.
