Task Management Backend Application

This is a backend application built with NestJS that allows users to create, view, and delete tasks. The application uses JWT tokens and cookies for authentication and authorization. User passwords are hashed using Argon2, MongoDB is used as the database, and Redis is used for caching.

Features

• User signup and login with JWT-based authentication.
• Task management: add, view, and delete tasks.
• Password hashing using Argon2 for enhanced security.
• Efficient data handling with caching and Redis.
• MongoDB for data storage.

Endpoints

Authentication

• POST /auth/signup: Register a new user.
• POST /auth/login: Login a user.
• POST /auth/logout: Logout a user and delete the session key.

Tasks

• GET /task/all: Fetch all tasks for the authenticated user.
• DELETE /task/delete: Delete a specified task.
• POST /task/add: Add a new task to the database.

Improvements

• Store the user ID in the JWT payload instead of the user email.
• Use a guard to check if there is data in the cookies before transferring the request to the route handler.
