Run the application :

bin/dev

Future improvements :

Task expiration :

• move task expiration to a state machine, with callbacks on state transition
• scheduled cron job with solid queue
• broadcast removal when task is expired
• pundit and policies to allow/prevent action if a task is expired

Task to task relationship : Not implemented

• add migration for parent_id
• fetching all_descendant_tasks can be optimized using SQL recursive query instead of active record for performance
• if there is a maximum deepness level on the task-to-task relationship, a Single Table Inheritance can also be implemented, with class : Task, Subtask, ... with different validations on the models

UI, Turbo, interface :

• stimulus controller for highlighting the project that has been selected
• stimulus controller that close all the other inline edit forms if edit is clicked
• "sub-tasks" with a parent task can be displayed dynamically with turbo and have another column on the right, or be displayed inline the task cards

Performance, optimization :

• add indexes for database
• pagination for tasks
