Demerzels-lab Cache Strategy
You know you should cache things but you're not sure what, where, or for how long. Point this tool at your API routes and get specific caching recommendations.
One command. Zero config. Just works.
Quick Start
npx ai-cache-strategy ./src/api/
What It Does
- Analyzes your API endpoints
- Identifies what should be cached
- Recommends TTL values based on data patterns
- Suggests caching layer (CDN, Redis, memory)
Usage Examples
# Analyze API routes
npx ai-cache-strategy ./src/api/
# Analyze specific route file
npx ai-cache-strategy ./routes/products.ts
# Get Redis-specific recommendations
npx ai-cache-strategy ./src/api/ --layer redis
Best Practices
- Cache static data aggressively - config, reference data, rarely changing content
- Be careful with user data - personalized responses need different strategies
- Invalidate properly - stale cache is worse than no cache
- Monitor hit rates - if nothing is hitting cache, something's wrong
When to Use This
- API response times are too slow
- Database is getting hammered with repeated queries
- Scaling up and need to reduce load
- Building a new API and want to design caching upfront

How It Works
Reads your API route files, understands the data patterns and access patterns from the code, and recommends appropriate caching strategies. The AI considers factors like data freshness requirements, personalization, and common access patterns.
