Task and Sub-task Backend Application

Overview

This is a Node.js backend application for managing tasks and sub-tasks. The application includes APIs for creating, updating, and deleting tasks and sub-tasks, as well as cron jobs for handling task priorities and initiating voice calls using Twilio.

Features

Main APIs

Create Task
- Endpoint: /api/task/create
- Input: Title, description, due_date (with JWT authentication)
Create Sub-task
- Endpoint: /api/subtask/create
- Input: task_id
Get All User Tasks
- Endpoint: /api/user/tasks
- Filters: Priority, due date, pagination
Get All User Sub-tasks
- Endpoint: /api/user/subtasks
- Filters: Task_id (if passed)
Update Task
- Endpoint: /api/task/update
- Updates: Due date, status ("TODO" or "DONE")

- Endpoint: /api/subtask/update
- Updates: Status (0 or 1)
Delete Task (Soft Deletion)
- Endpoint: /api/task/delete

- Endpoint: /api/subtask/delete

Cron Jobs

Task Priority Update
- Cron Logic: Change priority of tasks based on due date
- Priority:
  - 0: Due date is today
  - 1: Due date is between tomorrow and day after tomorrow
  - 2: 3-4 days from today
  - 3: 5 or more days from today
Voice Calling
- Cron Logic: Initiate voice calls using Twilio for overdue tasks
- Priority: Calls based on user priority (0, 1, 2)
- Behavior: Call the next user only if the previous user does not answer the call
