Hi Sivaprakash.
I only can guess. So my guess is that you will have to use what those frameworks support to render the information you get from the backend to the frontend.
Also I'm not sure if you should expect an official answer. As it is clearly stated:
"The upcoming features we are disclosing is our minimum plan that is subject to change without notice."
So at this point there is no guarantee that SnapDevelop will have those exact features.
By the way, if I was thinking about what technologie I would have to learn, I think React (native and - or JS) would be my choice, because I saw so many answers refferencing that framework, and because it's under MIT license.

We thought HTML DW will be your preference.
