Backend Authentication App

This is a Node.js-based backend project demonstrating authentication using JWT and session management with MongoDB for session storage. It includes user signup, login, and logout functionalities along with basic security features like rate limiting, helmet for security headers, CORS, and logging.

Features

• User Authentication: Signup, login, and logout routes.
• JWT: JSON Web Token generates and verifies tokens.
• Session Management: Sessions are stored in MongoDB, supporting secure cookies.
• Rate Limiting: Prevents abuse with a rate limit of 100 requests per 15 minutes.
• Security: Includes Helmet for setting security-related HTTP headers.
• CORS: Cross-Origin Resource Sharing is enabled.
• Custom Logging: Logs requests and errors to a custom logger.
• Testing: Includes test cases for user authentication using Jest
• Error Handling: Centralized error handling for all routes.
