+# Next.js Pages Router Webpack SVG Sprite Quick Start
+
+This guide targets the exact mode key `next@pages/webpack`: a generated typed React icon for the Next.js Pages Router and Webpack 5.
+
+## 1. Generate the sprite
+
+No package installation and no `package.json` dependency are needed. `npx` downloads the CLI temporarily, and generated runtime does not import `@gromlab/svg-sprites`.
+
+Keep the config adjacent to its source icons:
+
+```text
+src/ui/icons/
+├── icons/
+│   ├── check.svg
+│   └── folder.svg
+└── svg-sprite.config.ts
+```
+
+Use a plain default object export with no package import:
+
+```ts
+// src/ui/icons/svg-sprite.config.ts
+export default {
+  mode: 'next@pages/webpack',
+  name: 'icons',
+}
+```
+
+When `input` is omitted, SVG files are read from `./icons` relative to the config. A `.js` config with a default export and a `.json` config are also supported. Generate directly with:
+
+```bash
+npx --yes --package=@gromlab/svg-sprites@latest svg-sprites src/ui/icons/svg-sprite.config.ts
+```
+
+Generate once per invocation and keep the exact Webpack flags on both commands:
+
+```json
+{
+  "scripts": {
+    "sprites": "npx --yes --package=@gromlab/svg-sprites@latest svg-sprites src/ui/icons/svg-sprite.config.ts",
+    "dev": "npm run sprites && next dev --webpack",
+    "build": "npm run sprites && next build --webpack"
+  }
+}
+```
+
+Do not add `predev` or `prebuild` hooks to these scripts; that would run generation twice. In CI, replace `latest` with an exact package version.
+
+Generation creates a local `.gitignore`; commit that file once, but do not commit `.svg-sprite/`. Generated declarations are self-contained and do not require the package.
+
+### Production usage
+
+Import the generated component and icon-name list into a Pages Router page:
+
+```tsx
+// src/pages/index.tsx
+import {
+  IconsIcon,
+  iconsIconNames,
+} from '../ui/icons/.svg-sprite/index.js'
+
+export default function HomePage() {
+  return (
+    <main>
+      <IconsIcon icon="folder" width={24} height={24} aria-label="Files" />
+      <p>{iconsIconNames.length} icons available</p>
+    </main>
+  )
+}
+```
+
+The component works with SSR, SSG, and client-side navigation. Webpack resolves the generated SVG URL and CSS Module and emits a separate asset. Keep the mode and the `--webpack` dev/build flags aligned. If custom Next.js webpack rules process SVG through SVGR, exclude `.svg-sprite/sprite.svg` from those rules.
+
+## 2. Debug and preview
+
+This section is optional. Only users who need the Viewer or icon previews should install:
+
+```bash
+npm install --save-dev @gromlab/svg-sprites
+```
+
+Pages Router does not require an App Router Client Component boundary. Use the React bridge directly in a page with a static loader array:
+
+```tsx
+// src/pages/icon-debug.tsx
+import { SpriteViewer } from '@gromlab/svg-sprites/react'
+
+const sources = [
+  () => import('../ui/icons/.svg-sprite/svg-sprite.manifest.js'),
+]
+
+export default function IconDebugPage() {
+  return <SpriteViewer sources={sources} title="Project icons" />
+}
+```
+
+Keep the page internal or development-only. Viewer is not part of the production icon runtime.
+
+## 3. Type the config
+
+Choose one of these two paths.
+
+### With a local package installation
+
+After installing the package locally, use the helper:
+
+```ts
+import { defineSpriteConfig } from '@gromlab/svg-sprites'
+
+export default defineSpriteConfig({
+  mode: 'next@pages/webpack',
+  name: 'icons',
+})
+```
+
+You can alternatively import `type SpriteConfig` and apply `satisfies SpriteConfig`.
+
+### Without the package
+
+Copy a mode-specific type directly into the config:
+
+```ts
+type LocalSpriteConfig = {
+  mode: 'next@pages/webpack'
+  name?: string
+  description?: string
+  input?: string | string[]
+  transform?: {
+    removeSize?: boolean
+    replaceColors?: boolean
+    addTransition?: boolean
+  }
+  generatedNotice?: boolean
+}
+
+export default {
+  mode: 'next@pages/webpack',
+  name: 'icons',
+} satisfies LocalSpriteConfig
+```
