Overview

✨ FeaturesCopy Anchor Link

• ⚡ 64-bit Non-Cryptographic Hashing: Uses xxhash-wasm for lightning-fast, collision-resistant cache key generation.
• 💾 Multi-Tier Persistence: Supports memory-only, IndexedDB-only, or synchronized hybrid caching.
• 🛡️ Poisoned Cache Prevention: Built-in shouldCache predicate prevents caching failed promises, empty buffers, or placeholder errors.
• 🔀 Parallel Compute & Fetch: Executes cache lookup and generation simultaneously for zero-latency hits.
• 🧹 Automatic Cleanup: Time-based LRU-style cleanup using simpleCleanup based on access timestamps.
