Javascript library for phone case designs

I'm trying to create a web platform with a user interface as similar as possible to instagram histories / whatsapp histories. Where users can put emojis, text, ... with a touchable interface with gestures (mobile requests) and with a more simple library (web requests) to create a flat design and finally resize and adapt to their phone dimensions to design a personalized phone case.

I found some libraries like: http://ift.tt/2rTKh8v that solves the part of capture the gestures but not solves the web interface and the transformation of coordinates to the real phone case product. And also I found some libraries of product desing but had an horrible look and feel (no gestures).

There is any free product designer javascript library to make this? or very similar to my requeriments?

Thanks
