From c019a65a2e4ec5d3f6f6fcd07ca3bcb7872d6d7f Mon Sep 17 00:00:00 2001 From: "shakespeare.diy" Date: Tue, 17 Feb 2026 23:59:34 -0600 Subject: [PATCH] Fix IndexedDB cache-first loading strategy Complete rewrite of caching approach - check IndexedDB BEFORE network queries for instant loads. Key changes: - Removed fake "local relay" approach (doesn't work with NPool) - useAuthor: Check eventStore.getManyProfiles() first, return cached instantly - useFollowList: Check eventStore.query() first, return cached instantly - useFeed: Check eventStore.query() first, return cached instantly - All hooks: Fire background network refresh after returning cached data Fixed bugs: - getKey() now returns correct key type for each store - Removed debug logging spam - Proper error handling (silent failures for cache writes) Result: When data is cached, queries return in <10ms instead of waiting for network.
