Hi Sara,

You need to decide if this is a demo app or an app which you'll want to scale and maintain. For a quick demo, I would spin up a Node.js server with server rendered frontend using Handlebars template. This way, the whole project can be maintained in one repository without much moving parts.

If you are extracting data from image itself and not from a database, you wouldn't even need Node.js. Just a React app will do. Data extraction from image can be done on client side.
