A React Native component for caching and efficiently managing web images with automatic storage cleanup.
React Native CacheImage is a React Native component that caches web images locally to improve app performance and reduce network usage. It automatically manages image storage, tracks references, and enforces storage limits to keep cache sizes in check. The component ensures that images are only re-downloaded when their URLs change, typically through versioning in the filename.
React Native developers building mobile apps that display web images and need to optimize loading times and reduce data consumption.
It provides a simple drop-in replacement for the standard Image component with built-in caching logic, eliminating the need for manual cache management and offering automatic storage cleanup based on usage and size limits.
React Native CacheImage is a component that provides intelligent image caching for React Native applications. It automatically downloads and stores web images locally, reducing network requests and improving performance by serving cached images on subsequent loads.

Automatically downloads and stores web images locally, using cached files on subsequent loads to reduce network requests, as described in the README's logic for finding and reusing local files.
Implements reference counting to track image usage and deletes files only when no longer referenced, with a configurable total storage limit (default 50MB) that deletes the oldest files when exceeded.
Supports all standard React Native Image component props, making it a drop-in replacement that requires minimal code changes, as stated in the README.
Requires URL versioning (e.g., image_v1.jpg) to force downloads when images change, ensuring the cache reflects updated content, as per the README's format requirements.
Only supports JPG and PNG formats as specified in the URL suffix requirement, excluding common formats like GIF or WebP without workarounds.
Mandates that image URLs include version identifiers in the filename, which is inflexible for dynamic or CDN-based URLs that use other methods like query parameters for cache busting.
Uses a simple oldest-file deletion strategy when storage limits are exceeded, which may not optimize for access frequency or other metrics, lacking advanced options like LRU or TTL.
The README provides minimal examples and lacks details on error handling, offline support, or configuration options beyond basic usage, requiring developers to dig into source code for customization.
