To-Do List API

Objective: Build a RESTful API for a To-Do List application that allows clients to perform CRUD operations on tasks. The API should be secure, follow best practices, and use a database to store tasks persistently.

Requirements:

• Endpoints:
  • Create an endpoint to add a new task. Each task should include a title and a timestamp.
  • Create an endpoint to fetch all tasks in the database.
  • Create an endpoint to fetch a single task by its ID.
  • Create an endpoint to update a task (e.g., mark it as completed).
  • Create an endpoint to delete a task by its ID.
• Data Validation:
  • Validate incoming data for required fields (e.g., title).
  • Return appropriate error messages for invalid input or missing data.
• Database:
  • Use a relational database (e.g., MySQL, PostgreSQL) or a NoSQL database (e.g., MongoDB) to store tasks persistently.
• Data Model:
  • Each task should have a unique ID, title, timestamp, and a status field (e.g., "Pending" or "Completed").
• Security:
  • Implement basic authentication (e.g., API key or token-based authentication).

Stretch Goals (Optional):

• Paginate the list of tasks when fetching all tasks.
• Add search and filter functionality (e.g., filter by status or search by title).
• Implement rate limiting for the API.
• Deploy the API to a cloud service (e.g., AWS, Heroku).
• Write unit and integration tests for key functionality.
