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
