Hey Devs, In this post we are going to explore Production-grade folder structure for an e-commerce website. We will learn how to organize controllers and related components to build a production-grade application. The structure will look like this -
- Controllers: Handles authentication, user management, product handling, order processing, cart management, payments, and admin tasks.
- Models: Defines the database schema for users, products, orders, and more.
- Services: Contains business logic and interacts with the models and controllers.
- Routes: Maps API endpoints to the corresponding controllers.
- Middleware: Manages authentication, error handling, and logging.
- Utils: Provides utility functions for various operations.
- Configuration: Stores settings for database, server, authentication, and other services.
- Tests: Ensures the functionality of controllers, services, and routes.
- Documentation: Provides API and architectural documentation.
Here’s a detailed folder structure for an e-commerce website, including controllers and other essential components:

Key Components Explained:
-
controllers/: Manages the application's request handling. Each subdirectory represents a major functional area.-
auth/: Handles authentication-related functionalities. -
users/: Manages user accounts and profiles. -
products/(E-commerce): Manages content or product-related functionalities. -
orders/(E-commerce): Handles order processing and management. -
cart/(E-commerce): Manages shopping cart functionalities. -
payments/(E-commerce): Handles payment processing. -
admin/: Administrative tasks and management. -
notifications/: Manages notifications and alerts. -
reports/: Handles reporting and analytics. -
common/: Contains shared controllers for error handling and health checks.
-
models/: Contains database schema definitions for the application.services/: Encapsulates business logic and interacts with models and controllers.routes/: Defines API routes and associates them with controllers.middleware/:
Contains middleware for authentication, error handling, and logging.
utils/: Utility functions and helpers used throughout the application.config/: Configuration files for database, server, authentication, payment, and email settings.tests/: Contains unit and integration tests for controllers, services, models, and routes.docs/: Documentation related to API endpoints and system architecture.
This folder structure provides a clear separation of concerns, making it easier to manage, scale, and maintain both blog publishing and e-commerce applications.
