This project is a Todo application built with Node.js, Express, MongoDB for the backend, and React for the frontend.

• Register: Allows users to register with a unique username, email, and password. Passwords are hashed using bcrypt before storing in the database.
• Login: Authenticates users with email and password, issuing JWT tokens for authentication and refresh purposes.
• Logout: Logs out users by blacklisting tokens using a separate model in MongoDB.
• Token Refresh: Provides a route to refresh the JWT token using a refresh token mechanism.

• Create Todo: Creates a new todo item with specified fields such as title, priority, completion status, and timestamp.
• List Todos: Retrieves all todos associated with the authenticated user.
• Filter Todos: Retrieves todos based on title search query.
• Update Todo: Updates a specific todo item identified by its ID, ensuring only the owner can modify it.
• Delete Todo: Deletes a specific todo item identified by its ID, with permission validation.

The frontend of the application is built with React, leveraging components to interact with the backend API endpoints.

• User Authentication: Provides forms for user registration and login.
• Todo Management Interface: Displays todos fetched from the backend, with options to create, update, delete, and filter todos.
• Responsive Design: Ensures the application is usable on both desktop and mobile devices.
