Next.js App Router

← Back to home

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

npm install @gromlab/svg-sprites

2. Create a sprite module

src/ui/file-manager/svg-sprite/
├── icons/
│   ├── check.svg
│   └── folder.svg
└── svg-sprite.config.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:

{
  "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:

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:

'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

# 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.
