How can I implement lazy loading for images in a React application?

Asked on Dec 04, 2025

Answer

Lazy loading images in a React application can enhance performance by deferring the loading of images until they are needed, typically when they enter the viewport. This can be achieved using the Intersection Observer API or third-party libraries like `react-lazyload`.

<!-- BEGIN COPY / PASTE -->
    import React from 'react';
    import LazyLoad from 'react-lazyload';

    function ImageComponent() {
      return (
        <div>
          <LazyLoad height={200} offset={100}>
            <img src="path/to/image.jpg" alt="Description" />
          </LazyLoad>
        </div>
      );
    }

    export default ImageComponent;
    <!-- END COPY / PASTE -->

Additional Comment:

Install the `react-lazyload` package using npm or yarn before using it in your project.
The `offset` prop in `LazyLoad` can be adjusted to load images slightly before they enter the viewport.
Consider using native `loading="lazy"` attribute for simple cases without additional dependencies.
Ensure that images have defined dimensions to prevent layout shifts.
