• Open the terminal in the project directory and run npm i

• Setup the environment variables

• Run the application using node index.js

You have to create following APIs:

1. Create task - input is title, description and due_date with jwt auth token
2. Create sub task - input is task_id
3. Get all user task(with filter like priority, due date and proper pagination etc)
4. Get all user sub tasks (with filter like task_id if passed)
5. Update task- due_date, status-”TODO” or “DONE” can be changed
6. Update subtask - only status can be updated - 0,1
7. Delete task(soft deletion)
8. Delete sub task(soft deletion)

And the following cron jobs

1. Cron logic for changing priority of task based on due_date of task (refer below for priority)
2. Cron logic for voice calling using twilio if a task passes its due_date. Calling should be based on priority of the user, i.e. first the user with priority 0 should be called, then 1 and then 2. The user should only be called if the previous user does not attend the call. This priority should be fetched from the user table.

• Proper validation should be there while taking input and authenticating user for api calls
• Error handling should be implemented wherever necessary and user friendly error should be thrown
• You can use https://jwt.io/ for creating a jwt token with user_id and only corresponding decoding logic should be there
• You should also update the corresponding sub tasks in case of task updation and deletion
• Sub task model and user table is given, you have to make task model accordingly
• Task should also have priority and status (refer below for both)
• You can use postman to demonstrate all the apis

• id (int, unique identifier)
• task_id (int)//references task table
• status (0,1) //0- incomplete, 1- complete
• created_at (date/string)
• updated_at (date/string)
• deleted_at (date/string)
• User model
• id (int, unique identifier)
• phone_number (num)
• priority (0,1,2) //for twilio calling priority

• 0 - Due date is today //0
• 1 - Due date is between tomorrow and day after tomorrow // 1-2
• 2 - 3-4
• 3 - 5+

• “TODO” - when no sub task is finished
• “IN_PROGRESS” - when at least 1 sub task is finished
• “DONE” - when every sub task is completed
