Hierarchical, with TTL

Organise cache data into namespaces of any depth. Pass { ttl: ms } to set() and entries expire automatically — no background timer.

Observables, deduplicated

cacheObservable() wraps any HTTP call, caches the result, and shares one subscription across N concurrent callers via shareReplay. Built-in fallback on error.

Persistence with compression

Opt in to localStorage persistence with one provider call. Plug in LzStringCompressor to halve your snapshot size, or ship your own ICompressor.
