Project Requirements

This document outlines the key requirements, goals, and constraints for the frontend project.

Core Goals

1. Unified User Experience: Create a consistent user experience across all applications within the monorepo.
2. Code Reusability: Maximize code reuse through shared components and utilities.
3. Team Autonomy: Allow different teams to work independently on their applications while maintaining consistency.
4. Performance Optimization: Ensure fast loading times and smooth user interactions across all applications.
5. Accessibility: Make all applications accessible to users with disabilities.
6. Maintainability: Ensure the codebase is easy to maintain and extend over time.

Technical Requirements

Architecture

1. Maintain the monorepo structure using pnpm workspaces and Turborepo.
2. Follow the established project structure:
   • apps/: Contains the applications
     • common/: Common features provided by the main company
     • cs/, wr/, as/: Applications developed by different teams
   • packages/: Contains shared packages
     • common/: Common packages provided by the main company
       • assets/: Shared assets (styles, images, etc.)
       • components/: Shared UI components
       • business_components/: Business-specific components
       • config/: Shared configuration
       • network/: Network-related utilities

Development Standards

1. Use TypeScript for all code to ensure type safety.
2. Follow ESLint and Prettier configurations for consistent code style.
3. Implement comprehensive testing using Storybook for component development and testing.
4. Use Zustand for state management across applications.
5. Implement TanStack Query (React Query) for data fetching and caching.
6. Use Axios for HTTP requests.

UI/UX Requirements

1. Use Tailwind CSS for styling with consistent design patterns.
2. Implement Radix UI for accessible UI primitives.
3. Follow Shadcn UI patterns for component design.
4. Use TanStack Table for data tables and Chart.js for charts.
5. Ensure responsive design for all screen sizes.
6. Maintain a consistent color scheme and typography across all applications.

Constraints

1. Performance Budgets:

   • First Contentful Paint (FCP): < 1.8s
   • Time to Interactive (TTI): < 3.5s
   • Total Bundle Size: < 500KB (compressed)

2. Browser Support:

   • Support the last two versions of major browsers (Chrome, Firefox, Safari, Edge)
   • No support required for Internet Explorer

3. Deployment Constraints:

   • CI/CD pipeline must complete within 10 minutes
   • Zero-downtime deployments required

4. Team Constraints:

   • Multiple teams working on different applications
   • Need for clear boundaries and interfaces between teams
   • Varying levels of expertise with the technology stack

5. Technical Debt:

   • Some legacy code exists in certain applications
   • Need to gradually migrate to the new architecture

Future Considerations

1. Internationalization: Prepare for multi-language support in the future.
2. Theming: Consider implementing a theming system for white-labeling.
3. Mobile Applications: Prepare for potential React Native integration.
4. Micro-frontends: Evaluate the possibility of moving to a micro-frontend architecture.
