ziflux

ziflux is a lightweight caching library designed specifically for Angular 21+ applications. It provides stale-while-revalidate (SWR) semantics for Angular's built-in resource() function, enabling instant navigations, background data refreshes, and a smoother user experience by eliminating spinners on return visits.

Key Features

• Instant Navigations — Cached data appears immediately while fresh data loads in the background.
• Optimistic Updates — cachedMutation handles snapshot, mutate, and rollback-on-error lifecycle in just a few lines.
• Zero Dependencies — Built entirely on Angular signals and resource() with no external dependencies.
• Declarative API — Simple exports like cachedResource() and cachedMutation() reduce boilerplate.
• Developer Tools — Includes devtools for cache inspection and structured logging in development mode.
• Hierarchical Cache Keys — Prefix-based invalidation allows fine-grained cache control.

Philosophy

ziflux focuses solely on adding caching semantics to Angular's resource() — nothing more, nothing less. It embraces Angular's native signals and keeps the API surface minimal to reduce learning curve and maintenance overhead.
