I’m learning the MERN stack and building small projects. I usually put everything in simple folders, but when the project grows it becomes messy.

How should a proper MERN stack project be structured for scalability and maintainability?

- Folder structure for backend and frontend

- Best practices for controllers, routes, and services

- Handling environment variables

Would love to see examples from experienced developers.
