Acces to Unreal from web page

Hi there,
I want to access Unreal Engine variable or call function, events etc. I’ve been working 1 week to find a way. But I couldnt. Are there anyway to achive it?

I found something but not right result.

1- Umg to Slate (It is not web page but If I do it It will be fine) I just want need external page or widget .
2- UnrealJS. (But cant set result in realtime. I mean when my game running I should set or change something from web page or external widget)
3- SocketIO(I dont have any idea yet.)

So if possible can someone show me how to do it . Thanks for help. good work.
