Storage Utility

This `storage-utility` package, currently at version 3.1.3, provides a unified and persistent key-value storage solution for both web environments (using `localStorage` by default) and React Native applications (integrating with `AsyncStorage`). It aims to simplify cross-platform storage management. Since its 2.0.0 release, it supports time-based data expiration, allowing developers to store values with a defined lifespan, similar to HTTP cookies. A key feature introduced in version 3.0.0 is the transition to promise-based getter functions, primarily addressed through `GetItemAsync`, to robustly handle the asynchronous nature of storage engines like `AsyncStorage` and prevent race conditions encountered in earlier synchronous approaches. Additionally, the library offers a unique categorization of data into 'volatile' and 'nonVolatile' sets, enabling targeted data cleanup operations, such as clearing all user-specific 'volatile' data upon logout. It has an active release cycle, with significant updates in major versions focusing on stability, performance, and expanded functionality. Its core differentiator lies in its dual-platform support and advanced storage policies like time-based invalidation and data categorization.
