Authentication Module
Authentication Controller
File: auth.controller.ts or authentication.controller.ts
Responsibility: This controller file contains the logic and routes for handling authentication-related HTTP requests. It typically includes functions for user registration, login, logout, password reset, account verification, and other authentication-related operations. It communicates with the authentication service to process the requests and return appropriate responses.
Authentication Service
File: auth.service.ts or authentication.service.ts
Responsibility: This service file contains the core business logic for authentication operations. It typically includes functions for user registration, login, logout, password hashing, token generation, token validation, and other authentication-related functionality. It interacts with the data layer (such as a database) to perform operations on user accounts and authentication data.
File: auth.module.ts or authentication.module.ts
Responsibility: This module file is responsible for configuring and managing the authentication-related dependencies, providers, and controllers within your application. It typically imports and configures authentication services, guards, and any required modules. It sets up the overall authentication module and allows for its integration into the application.
Authentication Guard
File: auth.guard.ts or authentication.guard.ts
Responsibility: This guard file defines a guard or middleware that controls access to protected routes based on the user's authentication status and authorization permissions. It typically verifies the validity of the user's authentication token or session and allows or denies access to the requested resource accordingly. It can also handle authorization checks to ensure that users have the necessary permissions to access specific routes or perform certain actions.
Authentication Middleware
File: auth.middleware.ts or authentication.middleware.ts
Responsibility: This middleware file contains middleware functions that intercept incoming requests and perform authentication-related tasks before passing control to the appropriate route handler. It may handle tasks such as token authentication, session management, request validation, request logging, or other authentication-related operations.
