Caching for Cash
summary
Explains concrete rules and implementations: cache keys must include all inputs and missing one breaks correctness; use LRU or disk/SQLite/Redis to avoid unbounded memory, watch cache size and warm‑up cost, and prefer stale while revalidate or proactive invalidation over blind deletes. Calls out that SSG gives no inherent perf win versus server render + CDN, shows a real cache helper extracted into the library Cachefy (adds dedupe and soft purge), and demonstrates these approaches actually working in production.
