Ionic Cache

Ionic Cache is a caching service for Angular/Ionic apps that caches HTTP requests, observables, promises, and plain data. Version 6.0.3 is current. It uses Ionic Storage (IndexedDB, SQLite, WebSQL) as the backing store and supports configurable TTL, group invalidation, offline resilience, and delayed observable caching. It ships TypeScript types and requires @angular/common >=9.0.0, @angular/core >=9.0.0, and @ionic/storage-angular >=3 as peer dependencies. Key differentiators: tight Ionic/Angular integration, delayed observable pattern for seamless stale-while-revalidate behavior.
