From a7aff4551477761e7bd5035ecc5bf14fc0da6c1d Mon Sep 17 00:00:00 2001 From: npmrun <1549469775@qq.com> Date: Fri, 22 May 2026 09:48:00 +0800 Subject: [PATCH] feat(cache): add degrading cache system with Redis + memory fallback - Add packages/cache with CacheDriver interface (get/set/del/exists/clear) - Implement MemoryDriver (Map-based, TTL support) - Implement RedisDriver (ioredis, lazyConnect, error handling) - Implement CacheManager with manual fallback (Redis first, memory as backup) - Add createCache factory function for easy initialization - All dependency versions pinned per CLAUDE.md Co-Authored-By: Claude Opus 4.7 --- bun.lock | 17 +++++- packages/cache/index.ts | 35 +++++++++++ packages/cache/lib/drivers/memory-driver.ts | 48 +++++++++++++++ packages/cache/lib/drivers/redis-driver.ts | 88 +++++++++++++++++++++++++++ packages/cache/lib/managers/cache-manager.ts | 77 +++++++++++++++++++++++ packages/cache/lib/types.ts | 18 ++++++ packages/cache/package.json | 14 +++++ packages/cache/tsconfig.json | 10 +++ packages/drizzle-pkg/db.sqlite | Bin 40960 -> 45056 bytes 9 files changed, 305 insertions(+), 2 deletions(-) create mode 100644 packages/cache/index.ts create mode 100644 packages/cache/lib/drivers/memory-driver.ts create mode 100644 packages/cache/lib/drivers/redis-driver.ts create mode 100644 packages/cache/lib/managers/cache-manager.ts create mode 100644 packages/cache/lib/types.ts create mode 100644 packages/cache/package.json create mode 100644 packages/cache/tsconfig.json diff --git a/bun.lock b/bun.lock index 079ae12..825ecf2 100644 --- a/bun.lock +++ b/bun.lock @@ -7,8 +7,7 @@ "dependencies": { "@libsql/client": "0.17.3", "bcryptjs": "3.0.3", -
