TaskManagement

Project Overview

Develop a web application where teams can manage tasks collaboratively in real-time. Users can create projects, assign tasks, comment on tasks, and see updates instantly. The application will include:

• User Authentication and Authorization
• Real-time Features
• Background Jobs
• Data Encryption and Key Rotation
• Audit Logging
• Testing and Deployment

Key Features to Implement

1. User Authentication and Authorization

• User Registration and Login:
  • Implement using mix phx.gen.auth.
  • Secure password storage and authentication flow.
• Email Verification:
  • Send verification emails asynchronously using background jobs.
• Password Reset Functionality:
  • Allow users to reset passwords securely.
• Role-Based Access Control:
  • Define roles (Admin, Manager, User).
  • Restrict access to certain features based on roles.

2. Real-time Task Management

• Task Creation and Assignment:
  • Users can create tasks with details like title, description, due date.
  • Assign tasks to team members.
• Real-time Updates:
  • Use Phoenix LiveView or Phoenix Channels to broadcast updates.
  • Instantly reflect changes across all connected clients.
• Comments and Collaboration:
  • Allow users to comment on tasks.
  • Real-time comment updates.
• Presence Tracking:
  • Show online/offline status of users.
  • Display who is currently viewing or editing a task.

3. Background Jobs

• Email Notifications:
  • Use Oban to send emails when tasks are assigned or updated.
  • Handle email verifications and password resets asynchronously.
• Reminders and Alerts:
  • Schedule reminders for upcoming task deadlines.
  • Send daily or weekly summaries.
• Data Processing:
  • Offload heavy computations or data exports to background jobs.

4. Data Encryption and Key Rotation

• Sensitive Data Encryption:
  • Use the Cloak library to encrypt sensitive fields like personal information.
• Key Rotation:
  • Implement key rotation strategies to update encryption keys periodically.
  • Handle decryption of data encrypted with old keys using tagged ciphertext.
• Secure Key Management:
  • Store keys securely using environment variables or a secrets manager.
  • Implement versioning for keys.

5. Audit Logging

• Track User Actions:
  • Log actions like task creation, updates, deletions, and assignments.
• Immutable Logs:
  • Ensure audit logs are tamper-proof and immutable.
• Timestamp and User Identification:
  • Record when an action occurred and who performed it.
• Efficient Querying:
  • Design the database schema to allow efficient retrieval and analysis of logs.

6. Testing and Quality Assurance

• Unit and Integration Tests:
  • Write tests for all critical components.
• Testing Background Jobs:
  • Ensure jobs are enqueued and executed as expected.
• Encryption Tests:
  • Test encryption and decryption processes, including key rotation.
• Real-time Features Testing:
  • Simulate multiple users to test real-time updates and presence.

To start your Phoenix server:

• Run mix setup to install and setup dependencies
• Start Phoenix endpoint with mix phx.server or inside IEx with iex -S mix phx.server

Now you can visit localhost:4000 from your browser.
