`useImageLoad` is a custom React hook designed to enhance the user experience by efficiently loading images. It supports lazy loading to improve performance and provides detailed status updates during the image loading process.

- Progressive Image Loading: Displays a thumbnail first, followed by the full-resolution image once loaded.
- Lazy Loading Support: Defers the loading of off-screen images until they are needed.
- Detailed Loading States: Tracks the loading state, completion, and any errors that occur.
- SSR Safe: Checks for window object availability to ensure compatibility with server-side rendered applications.
- Cleanup Mechanism: Properly disconnects IntersectionObserver to prevent memory leaks.
``bash`
npm install @custom-react-hooks/use-image-load
or
`bash`
yarn add @custom-react-hooks/use-image-load
`sh`
npm install @custom-react-hooks/all

yarn add @custom-react-hooks/all
The useImageLoad hook must be imported using a named import as shown below:
Named Import:
`javascript`
import { useImageLoad } from '@custom-react-hooks/use-image-load';
This approach ensures that the hook integrates seamlessly into your project, maintaining consistency and predictability in how you use our package.
`typescript
import { useImageLoad } from '@custom-react-hooks/all';
const ImageLoadComponent = ({ thumbnailSrc, fullSrc }) => {
const thumbnailOnlyRef = useRef(null);
const lazyLoadRef = useRef(null);
const thumbnailOnlyState = useImageLoad({ thumbnailSrc, fullSrc: '' }, thumbnailOnlyRef);
const lazyLoadState = useImageLoad({ thumbnailSrc, fullSrc, lazyLoad: true }, lazyLoadRef);
return (
Loading thumbnail...
}Error loading thumbnail.
}Scroll down to trigger lazy load
Loading image...
}Error loading image.
}export default ImageLoadComponent;
`
: The source path of the thumbnail image.
- fullSrc: The source path of the full-resolution image.
- lazyLoad: (optional) A boolean to enable lazy loading.$3
- src: The current source of the image.
- isLoading: Indicates if the image is currently loading.
- isLoaded: Indicates if the image has fully loaded.
- hasError: Indicates if there was an error during loading.Use Cases
- Progressive Image Loading: Show a low-quality image or placeholder while the full image loads.
- Lazy Loading: Load images only when they are in or near the viewport, improving page load times.
- Error Handling: Handle image load errors gracefully with fallbacks or error messages.
- Loading State Indicators: Display a loading indicator while images are being fetched.
