## Structure 1 - Layered Modularization This structure is useful for medium to large projects where responsibilities are well divided. Each layer represents a part of the application (frontend, backend, config) and facilitates teamwork. ``` project-root/ │ ├── config/ │ ├── database.js │ └── server.js │ ├── src/ │ ├── controllers/ │ │ └── userController.js │ ├── models/ │ │ └── userModel.js │ ├── routes/ │ │ └── userRoutes.js │ ├── services/ │ │ └── authService.js │ └── utils/ │ └── helpers.js │ ├── public/ │ ├── css/ │ ├── images/ │ └── js/ │ ├── tests/ │ ├── controllers/ │ └── models/ │ └── index.js ``` ## <br>Structure 2 - Modularization by Functionality In this structure, the organization is done by functionality. Each module includes all the layers (controller, model, etc.) in the same directory. Ideal for projects with independent functionality. ``` project-root/ │ ├── config/ │ ├── database.js │ └── server.js │ ├── modules/ │ ├── auth/ │ │ ├── authController.js │ │ ├── authModel.js │ │ ├── authRoutes.js │ │ └── authService.js │ ├── user/ │ │ ├── userController.js │ │ ├── userModel.js │ │ ├── userRoutes.js │ │ └── userService.js │ ├── public/ │ ├── css/ │ ├── images/ │ └── js/ │ ├── tests/ │ └── modules/ │ ├── auth/ │ └── user/ │ └── index.js ``` These are the most appropriate folder structures for web applications.
