# Next.js App Router
|
||
|
||
[← Back to home](../../README.md)
|
||
|
||
Two explicit modes are supported:
|
||
|
||
| Bundler | Mode key | Next.js version |
|
||
|---|---|---|
|
||
| Turbopack | `next@app/turbopack` | 16.2+ |
|
||
| Webpack 5 | `next@app/webpack` | 13.4+ |
|
||
|
||
## 1. Install the package
|
||
|
||
```bash
|
||
npm install @gromlab/svg-sprites
|
||
```
|
||
|
||
## 2. Create a sprite module
|
||
|
||
```text
|
||
src/ui/file-manager/svg-sprite/
|
||
├── icons/
|
||
│ ├── check.svg
|
||
│ └── folder.svg
|
||
└── svg-sprite.config.ts
|
||
```
|
||
|
||
```ts
|
||
// src/ui/file-manager/svg-sprite/svg-sprite.config.ts
|
||
import { defineNextSpriteConfig } from '@gromlab/svg-sprites'
|
||
|
||
export default defineNextSpriteConfig({
|
||
name: 'file-manager',
|
||
description: 'File manager icons',
|
||
})
|
||
```
|
||
|
||
## 3. Add generation
|
||
|
||
For Turbopack:
|
||
|
||
```json
|
||
{
|
||
"scripts": {
|
||
"sprite:file-manager": "svg-sprites --mode next@app/turbopack src/ui/file-manager/svg-sprite",
|
||
"predev": "npm run sprite:file-manager",
|
||
"prebuild": "npm run sprite:file-manager"
|
||
}
|
||
}
|
||
```
|
||
|
||
For Webpack, replace the mode key with `next@app/webpack`. In Next 13–15, Webpack is used with the regular `next build` command; in Next 16, use `next build --webpack`.
|
||
|
||
## 4. Use it in a Server Component
|
||
|
||
The generated component does not contain `'use client'`, so it can be imported directly into `page.tsx` or `layout.tsx`:
|
||
|
||
```tsx
|
||
import { FileManagerIcon } from '@/ui/file-manager/svg-sprite'
|
||
|
||
export default function Page() {
|
||
return (
|
||
<main>
|
||
<FileManagerIcon icon="folder" width={24} height={24} />
|
||
</main>
|
||
)
|
||
}
|
||
```
|
||
|
||
Next.js emits a separate SVG asset with a content hash. The same generated code is used during SSR and in the browser, with no URL mismatch.
|
||
|
||
## 5. Add SpriteViewer
|
||
|
||
The viewer is interactive, so it requires a separate Client Component boundary:
|
||
|
||
```tsx
|
||
'use client'
|
||
|
||
import { SpriteViewer } from '@gromlab/svg-sprites/react'
|
||
|
||
const sources = [
|
||
() => import('@/ui/file-manager/svg-sprite/manifest'),
|
||
]
|
||
|
||
export default function SpritesPage() {
|
||
return <SpriteViewer sources={sources} />
|
||
}
|
||
```
|
||
|
||
## Verify the bundler
|
||
|
||
```bash
|
||
# Turbopack
|
||
npx next build --turbopack
|
||
|
||
# Webpack 5
|
||
npx next build --webpack
|
||
```
|
||
|
||
For Next 13–15 with Webpack, use `npx next build` without the flag.
|
||
|
||
The Next.js command and the generator mode key must target the same bundler.
