Task Management API

🚀 Overview

This project is a Task Management API built with Node.js, Express, and MongoDB, featuring JWT-based authentication, task CRUD operations, filtering, sorting, and validation using Zod.

📌 Features

• User Authentication

  • User registration & login with JWT authentication.
  • Passwords securely stored using bcrypt.

• Task Management

  • Users can create, update, delete, and retrieve tasks.
  • Each task includes:
    • id (UUID)
    • title (required)
    • description (optional)
    • status (pending, in-progress, completed)
    • dueDate (optional)
    • createdAt (timestamp)
  • Only the task creator can modify or delete it.

• Filtering & Sorting

  • Filter tasks by status and dueDate.
  • Sort tasks by createdAt (ascending/descending).

• Input Validation & Error Handling

  • Used Zod for request validation.
  • Proper error handling for invalid inputs.

• Bonus Features (Optional Enhancements)

  • Pagination for task listing.
  • Clean and structured code following best practices.
