LLama 2 Chatbot Frontend Development with JS+React

I have LLama 2 chatbot prototype which runs on AWS Bedrock. It is still very simply (see the attached screenshot). It is programmed entirely in python and uses the python libraries. To make it ready for future front-end development, I want it to be written in JavaScript with react. The only addition at this point is a backend allowing to upload files for LLama 2.
