Backend Issue: Create API for User Authentication

[BhattAnsh]

Description

We need backend API endpoints to handle user authentication and registration for our Login/Signup feature. These endpoints will communicate with the database to store user information securely and manage authentication.

Requirements

•	Login Endpoint:
•	Accepts: Email, Password
•	Verifies user credentials and returns an authentication token (JWT).
•	Signup Endpoint:
•	Accepts: Name, Email, Password
•	Saves user details to the database after validation.
•	Returns a success response or an error (e.g., “Email already exists”).
•	Validation:
•	Validate email format and password strength.
•	Check for duplicate email during registration.
•	Error Handling:
•	Return meaningful error messages (e.g., “Invalid credentials”).

Tech Stack

•	Framework: Node.js/Express.js
•	Database: MongoDB (or the database used in the project).
•	Authentication: JWT-based authentication.

Contribution Guidelines

1.	Fork the repository and create a new branch.
2.	Implement the feature and test it with Postman or similar tools.
3.	Submit a pull request with API documentation.

How are you going to work on this issue? what is your approach?

[srujanGowda08]

I would like to work on this issue and propose the following approach:
For the signup endpoint, I will implement input validation to ensure proper email format and password strength, followed by a duplicate email check in the database. Passwords will be securely hashed using bcrypt before saving the user data to the database. For the login endpoint, I will authenticate user credentials by comparing the hashed password stored in the database and, upon successful verification, generate a JWT token to manage user sessions. Both endpoints will include comprehensive error handling to return meaningful and descriptive messages, such as "Email already exists" or "Invalid credentials."

The implementation will leverage Node.js and Express.js for the backend, MongoDB as the database, and JWT for secure authentication. I will thoroughly test the endpoints using Postman and provide well-documented API endpoints in the pull request.
