🗄️ Taskify Backend

Taskify Backend is a secure RESTful API built with Express.js and MongoDB. It powers the Taskify task management app, providing endpoints for user authentication and personal task management.

✨ Features

• User Authentication:

  • Signup and login with JWT-based session management.
  • Passwords are securely hashed with bcrypt.
  • Input validation with Zod for strong security.
  • All protected routes require a valid token.

• Task Management:

  • Create, read, update, and delete your own tasks.
  • Strict validation for all fields and enums.
  • Each task supports title, description, priority tag, deadline, status (section), and done flag.
  • Fetch all tasks or a specific task by ID.

• Secure & Modular:

  • All user and task data is scoped per user.
  • Modular route structure for users and todos.
  • Uses environment variables for secrets and database config.
