Caching

Caching Guidelines

Efficient caching improves performance, reduces server load, and enhances user experience in DevTrack.

API Response Caching

Use caching for GET requests where data does not change frequently.

Cache-Control: public, max-age=300, stale-while-revalidate=600

Frontend Caching

Use tools like React Query or SWR to cache API responses and reduce unnecessary network requests.

Server-Side Caching

Use Redis or in-memory caching for:

• Expensive computations
• Repeated database queries
• Frequently accessed data

Static Asset Caching

Enable long-term caching for static assets:

Cache-Control: public, max-age=31536000, immutable

Cache Invalidation Strategy

Always invalidate cache when underlying data changes using:

• Versioning
• Timestamps
• Manual invalidation

Best Practices

• Do not cache sensitive data
• Always define TTL (Time To Live)
• Monitor cache hit/miss ratio for performance optimization
