FocusFlow MVP Implementation Strategy

1. Core Features for MVP

1. Kanban Board (Trello-like)
2. Productivity Homepage
3. Basic Sidebar
4. Simple Pomodoro Timer

2. Technology Stack

• HTML5, CSS3, and TypeScript for the frontend
• React 18 for building the Single Page Application (SPA)
• Next.js 13 for server-side rendering and routing
• Tailwind CSS for styling and responsive design
• IndexedDB for local data storage

3. Data Management

• Use IndexedDB for offline data storage
• Implement data models for tasks, boards, lists, and user preferences
• Ensure all data operations are synchronous and local
• Utilize React Query for efficient data fetching and caching

4. Feature Implementation

4.1 Kanban Board (Trello-like)

• Create a drag-and-drop interface using react-beautiful-dnd
• Implement customizable lists (columns) with the ability to add, rename, and delete
• Allow adding, editing, moving, and archiving cards (tasks)
• Implement card features:
  • Title and description
  • Due dates and reminders
  • Labels and color coding
  • Checklists
  • Attachments (local file references)
  • Comments
• Enable board customization (background, visibility)
• Implement board sharing functionality (for future multi-user support)
• Store board state in IndexedDB
• Use Tailwind CSS classes for layout and styling

4.2 Productivity Homepage

• Design a simple, clean interface displaying:
  • Kanban board overview with recent activity
  • Top priority tasks across all boards
  • Current date and time
  • Quick-add card functionality
• Fetch and display data from IndexedDB using React Query
• Utilize Tailwind CSS utility classes for responsive design

4.3 Basic Sidebar

• Create a collapsible sidebar using React components and Tailwind CSS
• Include:
  • Navigation to different boards
  • Quick-add card functionality
  • Mini view of top priority tasks
  • Pomodoro timer controls
  • Search functionality across all boards and cards
• Implement dark theme styling using Tailwind's dark mode classes

4.4 Simple Pomodoro Timer

• Implement a basic timer with preset work/break intervals
• Use React hooks for timer functionality
• Provide start, pause, and reset controls styled with Tailwind CSS
• Implement browser notifications for audio-visual alerts
• Allow customization of work/break durations

5. User Interface Design

• Design a clean, minimalist UI using Tailwind CSS utility classes
• Implement a dark theme by default using Tailwind's dark mode
• Use a limited color palette for consistency, defined in tailwind.config.js
• Ensure responsive design for various screen sizes using Tailwind's responsive utilities
• Implement basic animations for smooth user experience with Tailwind's transition classes
• Create custom card and list designs mimicking Trello's aesthetic

6. SPA Setup

• Set up a Next.js project with TypeScript support
• Implement Next.js App Router for navigation between different views (boards, cards)
• Use React Context API or Redux Toolkit for state management across components
• Configure Tailwind CSS for the project

7. Offline Functionality

• Implement a Service Worker for offline caching using next-pwa
• Ensure all features work without an internet connection
• Implement error handling for offline scenarios
• Sync data when connection is restored (for future online functionality)

8. Testing

• Develop unit tests for React components using React Testing Library and Jest
• Perform end-to-end testing using Cypress
• Test data persistence across browser restarts
• Ensure dark theme and responsive design are working correctly across different devices
• Test drag-and-drop functionality extensively

9. Performance Optimization

• Minimize DOM manipulation by leveraging React's virtual DOM
• Use efficient data structures for task and board management
• Implement lazy loading for Kanban board tasks and routes using Next.js dynamic imports
• Optimize Tailwind CSS by purging unused styles in production
• Implement virtual scrolling for boards with many cards using react-window

10. Documentation

• Create inline code documentation
• Develop a comprehensive user guide for application usage
• Document data models and storage schema
• Include documentation on Tailwind CSS usage and custom configurations
• Provide API documentation for future extensibility

11. Deployment

• Set up a CI/CD pipeline for automated testing and deployment
• Deploy the Next.js app to a serverless platform (e.g., Vercel)
• Implement basic usage analytics using a service like Plausible or a self-hosted solution
• Ensure proper bundling and minification of Tailwind CSS for production

12. Future Considerations

• Plan for modular code structure to ease future feature additions
• Design data models with potential cloud sync in mind
• Consider progressive web app (PWA) implementation for enhanced offline capabilities
• Explore advanced Tailwind CSS features like custom plugins for extending functionality
• Implement real-time collaboration features using WebSockets or Firebase
• Develop integrations with popular tools and services
• Create mobile apps for iOS and Android using React Native
