2.1 Frontend

Goal: Deliver a consistent, high-performance user experience across web and iOS, focusing on real-time data, intuitive interfaces, and social engagement.

1. Web App (React)

• Architecture: Single Page Application using React.

UI/UX:

• Responsive design for desktop + mobile.

• Component libraries (Material UI / Ant Design) to accelerate development.

• Custom charts (e.g., Highcharts, Recharts, or D3) for displaying real-time coin prices.

State Management:

• Redux Toolkit or MobX for global state (user profiles, chat channels, live trades).

• Context API for localized states.

• Communication with Backend:

• REST endpoints (user auth, posts, trade actions).

• WebSocket (Socket.io) for live chat, market updates, voice/video session signaling.

Performance Optimizations:

• Code splitting and lazy loading for large routes/components.

• Websocket streaming to reduce polling overhead.

• CDN-hosted static assets (images, JS bundles).

Testing:

• Jest + React Testing Library for unit tests.

• Cypress or Playwright for end-to-end flows (login, trade execution, chat).
