A simple yet powerful image component for React Native, powered by Glide (Android) and SDWebImage (iOS).
Caching remote images has always been a challenge for me with the Image component in React Native. This simplified, yet powerful component, addresses that issue head-on. It offers a robust and performant mechanism for caching remote images, ensuring they're displayed quickly.
Leveraging the strengths of Glide and SDWebImage, it supports both memory and disk caching for remote images. Notably, while it provides these enhanced capabilities for remote images, it seamlessly integrates with the standard React Native Image component when handling local assets.
- Performance: Bypasses the React Native Image component for remote images ensuring immediate and lightning-fast display of remote images.
- Cross-Platform: Works on both Android (with Glide) and iOS (with SDWebImage)
- Customizable: Wrapped within a
Viewfor added layout and style customization. - Robust Caching: Benefits from both memory and disk caching for maximum performance.

]);| Method | PropType | Description |

Array<{ uri: string, skipMemoryCache: bool }> |
Preloads remote images from an array of URIs, with the option to preload only to disk. |
BlastedImage.clearDiskCache() |
- | Clears the disk cache for all images. |
BlastedImage.clearMemoryCache() |
- | Clears the memory cache for all images. |
BlastedImage.clearAllCaches() |
- | Clears both disk and memory caches for all images. |
import { NativeEventEmitter, NativeModules } from 'react-native';
const BlastedImageEvents = new NativeEventEmitter(NativeModules.BlastedImage);
useEffect(() => {
const subscription = BlastedImageEvents.addListener('BlastedEventLoaded', (data) => {
console.log(data.message);
});
return () => {
subscription.remove();
};
}, []);| Event | Description |
|---|---|
BlastedEventLoaded |
Triggered when remote images are successfully loaded. |

This component was created with inspiration from react-native-fast-image that also uses Glide and SDWebImage. But due to its lack of ongoing maintenance i felt the need to develop this new image component to continue providing robust and performant caching functionality.
