can I have two react app in the same folder with the same package.js file

I want to run two apps using same package and node_modules, is this possible ? I've a project with is already build with serverless framework but I want to put a single page along side it which will be created using react or next, so is it possible to do so. and why I want to do so is that I want to consume some logic from the serverless inside the new react app
