The Challenge
Building a high-performance cryptocurrency dashboard that could handle frequent API calls while providing a responsive user experience presented multiple challenges. The primary concerns were efficient data fetching, caching strategies to avoid rate limits, and creating an architecture that would scale with additional features.
The Solution
I implemented a multi-layered API architecture with Redis-powered caching and comprehensive middleware to optimize performance. This approach focused on both developer experience and end-user satisfaction through intelligent caching, detailed request tracing, and robust error handling.
Technical Implementation
Advanced API Infrastructure
- •Implemented TTL-based cache invalidation with Redis
- •Created IP-based rate limiting to prevent API abuse
- •Built request tracing with unique IDs for debugging
- •Set up comprehensive security headers (CSP, HSTS)
Frontend Architecture
- •React 19 with TypeScript for type safety
- •React Query for data fetching and state management
- •Interactive charts powered by Recharts
- •Responsive design optimized for all device sizes
Caching Strategy
- •Short-lived cache (60s) for volatile data like current prices
- •Medium-lived cache (5min) for market overviews
- •Long-lived cache (30min) for historical data
- •Multi-tiered caching (Redis + React Query) to minimize API calls
Performance Optimizations
- •Server-side rendering for initial page load performance
- •Incremental Static Regeneration for static content
- •Optimized image loading with Next.js Image component
- •Efficient re-renders with React optimization techniques
