  • Count Cachula offers local-first performance without complexity.
  • Features include instant UI updates, cache tags, invalidation, and smart preloading.
  • Benefits: Fast (serve cached content instantly), Fresh (automatic cache invalidation), Simple (drop-in replacement for fetch).
  • Alternative to local-first architectures, avoiding CRDTs, conflict resolution, and sync protocols.
  • Stale-while-revalidate approach: cache as truth, server remains source of truth.
  • Instant response with background revalidation, cache tags for group invalidation, smart invalidation via SSE, and preloading.
  • Users see data instantly, data stays fresh automatically, server remains source of truth, and it's a drop-in replacement for fetch.
  • Works via SSE connection for server-driven invalidation and preloading.
  • Server sends preload hints to warm up cache, mutations invalidate tags, and clients update automatically via SSE.
  • Progressive enhancement: start simple, add features like SSE, cache tags, and preloading as needed.
  • Documentation includes core library, SSE package, and React hooks.
