/controllers - Contains the logic for handling API requests and generating responses. Each controller manages one or more API endpoints and is responsible for interacting with models and services
/middleware - Stores custom middleware used for pre-processing requests before they hit your controllers. This is often used for validation, authentication, error handling, and logging.
/models - Defines the data structures for your API, usually connected to a database (MongoDB, PostgreSQL, etc.). This is where schemas or database models are stored.
/routes - Defines the API endpoints and maps them to corresponding controller functions. Organize the routes based on the resources they represent.
/services - Contains the business logic or service layer for your API. Services are typically responsible for interacting with models and external APIs, processing data, or performing other complex operations.
/utils - Holds utility functions used across your API, such as common helpers for data validation, logging, or formatting.
/tests - Contains tests for your API endpoints. This folder is essential for unit and integration testing, ensuring the correctness of your API's behavior.
/config - Contains configuration files like database connection settings, environment variables, or API key management. This is typically where you manage environment-dependent configurations.
.env - Holds sensitive data like database credentials, API keys, and other environment-specific variables. Never commit this file to version control.
app.js (or server.js) - The main entry point to your API. This is where you set up the Express application, middleware, and routes, and start the server.
