Setting Up svg-sprite-loader
Install svg-sprite-loader and configure it in your webpack.config.js to process a directory of individual SVG icon files, automatically generating a combined sprite with each icon as a reusable <symbol>.
- Install svg-sprite-loader and add it to your webpack module rules
- Point the loader at your icons directory with a glob pattern
- Each icon becomes a <symbol> referenced via <use> in your app
Using Sprite Icons in Components
Reference sprite icons in your components with an SVG <use> element pointing to the symbol id, allowing you to reuse the same loaded sprite sheet for every icon instance without duplicate markup.
- Use <svg><use href='#icon-name'/></svg> to render a sprite icon
- Single sprite sheet loads once and serves all icon instances
- Reduces total markup and improves caching versus inline SVG everywhere
Frequently Asked Questions
Why use a sprite instead of inline SVG for every icon?
A sprite loads once and is cached, while inline SVG duplicates markup for every instance — sprites reduce page weight when using many repeated icons.
Can I still style sprite icons with CSS?
Yes — the SVG symbols inherit CSS styling like fill and stroke through the use element, as long as the original SVG paths don't have hardcoded colors.
