API Summary for To-Do App

API is built with Express.js and PostgreSQL and it manages task operations for the To-Do app. Key functionalities include:

1. Task Retrieval:

- `/completedtasks`: Retrieves all tasks marked as "Complete," sorted by the due date.

- `/progresstasks`: Retrieves all tasks in "In-Progress" status, also sorted by the due date.

- `/todo_latest`: Fetches the most recently created task.

2. Task Creation:

- `/todo`: Allows users to create a new task. Tasks are stored with a unique ID, title, description, due date, creation date, and an initial "In-Progress" status.

3. Task Updates:

- `/update_task`: Updates the title, description, and due date of an existing task.

- `/statuscomplete`: Marks a task as "Complete."

- `/statusinprogress`: Changes a task's status back to "In-Progress."

4. Task Deletion:

- `/todo`: Deletes a task by its unique ID.

The API utilizes modules pg-promise for PostgreSQL interactions, short-uuid for generating task IDs, and CORS for handling cross-origin requests. Task data is managed with JSON-based requests and responses.
