Svelte Image

Overview:

The Svelte Image Demo is a preprocessor that automates image optimization using sharp. It optimizes and inlines image tags, replaces src accordingly, and enables lazyloading and serving multiple sizes via srcset. Inspired by Gatsby Image, this package requires installation as a dev dependency in Svelte projects. The library currently works with paths from root in Sapper, and it also provides configuration options for image components.

Features:

• Generate and add responsive images
• Set base64 placeholder
• Optimize normal images using img tag
• Image lazy loading
• Optional SVG trace placeholder
• Support WebP
• Optimize background or whatever images found in CSS (not yet supported)
• Resolve imported images (only works with string pathnames at the moment)

Installation:

To use Svelte Image in your Svelte project, follow these steps:

1. Add svelte-image as a dev dependency.
2. In your rollup.config.js, add image to the preprocess section.
3. Use the provided configurations and defaults for the Image component.
4. If using Sapper, note that the library only works with paths from root at the moment. Image paths should start with a / to represent actual paths.
5. Copy the generated static/g folder to the public folder if not using Sapper.

Summary:

The Svelte Image Demo is a preprocessor that automates image optimization in Svelte projects. It provides features such as generating responsive images, setting placeholders, lazy loading, supporting WebP, and optimizing normal images using img tags. However, the library only works with paths from root in Sapper and does not yet support optimizing background images or resolving imported images. Overall, it is a useful tool for optimizing images in Svelte applications.
