Svelte Lazy Image

Overview

The svelte-lazy-image is a Svelte component that allows for the lazy loading of images using Intersection Observer. It provides an efficient way to load images only when they are visible within the viewport, reducing initial load times and improving page performance.

Features

• Lazy Loading: Images are loaded only when they are visible in the viewport.
• Intersection Observer: Utilizes the Intersection Observer API to determine if an image is visible.
• Flexible Usage: Can be easily integrated into Svelte projects with simple steps.

Installation

To install the svelte-lazy-image component, you can use either npm or yarn. Simply run the following command in your project’s directory:

npm install svelte-lazy-image

or

yarn add svelte-lazy-image

After installing the package, you can import and use the component in your Svelte project as follows:

import LazyImage from 'svelte-lazy-image';

// Inside your Svelte component
<LazyImage src="image.jpg" alt="Image" />

// You can also set additional attributes
<LazyImage src="image.jpg" alt="Image" data-srcset="image-1.jpg 1x, image-2.jpg 2x" />

The svelte-lazy-image component takes two required attributes: src and alt. Optionally, you can also set data-srcset attribute to specify different image sources for different device pixel ratios.

Summary

The svelte-lazy-image component provides an efficient way to lazy load images in Svelte projects using Intersection Observer. By deferring the loading of images that are not in the viewport, it improves page performance and reduces the initial load time. Its easy integration and flexible usage make it a useful tool for optimizing image loading in Svelte applications.
