caching

What problem does it solve?

This Skill enforces a consistent 4-layer caching strategy, eliminating redundant data fetches and ensuring optimal application performance across React, Next.js, Redis, and Cloudinary, while simplifying cache invalidation.

Core Features & Use Cases

• Multi-Layered Caching: Guides the use of React cache(), Next.js unstable_cache(), Upstash Redis, and Cloudinary for appropriate caching scenarios.
• Standardized Cache Keys & Tags: Enforces the use of CACHE_KEYS, REDIS_KEYS, and CacheTagGenerators for consistent and effective cache management.
• Coordinated Cache Invalidation: Ensures mutations trigger precise cache invalidation using CacheRevalidationService to maintain data freshness.
• Use Case: When implementing a public search endpoint, this Skill guides the use of CacheService.redisSearch.publicDropdown() for high-traffic queries, ensuring appropriate REDIS_TTL and createHashFromObject() for key generation, and CacheService.search.invalidatePublic() for invalidation.

Quick Start

Implement caching for a public API endpoint that fetches a list of 'Featured Products', using CacheService.featured.content() and ensuring proper cache invalidation upon product updates.
