How to optimize image loading in a React app using lazy loading with React Lazy Load Image Component?
I'm optimizing some code but I'm updating my dependencies and I'm having a hard time understanding I'm performance testing and I'm trying to figure out I've been struggling with this for a few days now and could really use some help..... I'm currently working on a React application where I need to implement lazy loading for images to improve performance. I've been using the `react-lazy-load-image-component` library (version 1.6.4) to handle this, but I'm working with a question where some images are not loading as expected. Here's the code I have so far: ```javascript import React from 'react'; import { LazyLoadImage } from 'react-lazy-load-image-component'; import 'react-lazy-load-image-component/src/effects/blur.css'; const ImageGallery = () => { const images = [ 'https://example.com/image1.jpg', 'https://example.com/image2.jpg', 'https://example.com/image3.jpg' ]; return ( <div> {images.map((image, index) => ( <LazyLoadImage key={index} src={image} alt={`Image ${index}`} effect="blur" width="100%" height="auto" /> ))} </div> ); }; export default ImageGallery; ``` The scenario arises when I scroll through the gallery quickly; some images either do not load at all or show a broken image icon. I've ensured that the images are accessible and verified their URLs. I even tried setting a custom `placeholder` and `onError` to handle failed loads, but they don’t seem to work effectively: ```javascript <LazyLoadImage src={image} alt={`Image ${index}`} effect="blur" placeholder={<img src="/path/to/placeholder.png" alt="Loading..." />} onError={(e) => { e.target.onerror = null; e.target.src="/path/to/behavior.png"; }} /> ``` I also inspected the network tab and noticed that the images aren’t even requested in some cases. I suspect it might be related to how I'm using the library or maybe something to do with the viewport settings. Could anyone suggest best practices for implementing lazy loading correctly in this context or if there's a specific configuration I might be missing? Any insights would be greatly appreciated! This is my first time working with Javascript LTS. Any advice would be much appreciated. What would be the recommended way to handle this? My team is using Javascript for this microservice. I appreciate any insights! I'm working in a Ubuntu 20.04 environment. Is there a better approach?
