+# SVG Sprite for Preact with Webpack
+
+A quick guide to creating an SVG sprite in a Preact application built with Webpack 5.
+
+## Generate the sprite
+
+Choose a directory for the future SVG sprite, for example `assets/app-icons`, and create `svg-sprite.config.json` inside it. In `input`, specify the path to existing SVG files relative to the configuration file. There is no need to move or copy the icons.
+
+```json
+{
+  "mode": "preact@webpack",
+  "name": "app",
+  "input": "../svg-icons/**/*.svg"
+}
+```
+
+The package does not need to be a project dependency. Run it through `npx` before Webpack starts or builds:
+
+```json
+{
+  "scripts": {
+    "sprites": "npx --yes @gromlab/svg-sprites assets/app-icons/svg-sprite.config.json",
+    "predev": "npm run sprites",
+    "dev": "webpack serve --mode development",
+    "prebuild": "npm run sprites",
+    "build": "tsc --noEmit && webpack --mode production"
+  }
+}
+```
+
+## Use the sprite
+
+Create `assets/app-icons/index.js` and `assets/app-icons/index.d.ts` with the same export:
+
+```js
+export * from './.svg-sprite/index.js'
+```
+
+Use the generated Preact component:
+
+```jsx
+import { AppIcon } from '../assets/app-icons/index.js'
+
+export function SaveIcon() {
+  return (
+    <AppIcon
+      icon="icon-name"
+      width={24}
+      height={24}
+      aria-label="Done"
+      style={{ color: '#334155', '--icon-color-2': '#f59e0b' }}
+    />
+  )
+}
+```
+
+Webpack Asset Modules emit `sprite.svg` from the generated `new URL(...)` expression.
+
+## Debug and preview
+
+Install Viewer only for development:
+
+```bash
+npm install --save-dev @gromlab/svg-sprites
+```
+
+Mount it from a development-only entry:
+
+```js
+import '@gromlab/svg-sprites/viewer/element'
+
+const viewer = document.createElement('gromlab-sprite-viewer')
+viewer.sources = [() => import('../assets/app-icons/.svg-sprite/svg-sprite.manifest.js')]
+document.body.append(viewer)
+```
