description: Learn how to enable FileSystem Caching for Turbopack builds
|
|
---
|
|
|
|
## Usage
|
|
|
|
Turbopack FileSystem Cache enables Turbopack to reduce work across `next dev` or `next build` commands. When enabled, Turbopack will save and restore data to the `.next` folder between builds, which can greatly speed up subsequent builds and dev sessions.
|
|
|
|
> **Good to know:** The FileSystem Cache feature is considered stable for development and experimental for production builds
|
|
|
|
```ts filename="next.config.ts" switcher
|
|
import type { NextConfig } from 'next'
|
|
|
|
const nextConfig: NextConfig = {
|
|
experimental: {
|
|
// Enable filesystem caching for `next dev`
|
|
turbopackFileSystemCacheForDev: true,
|
|
// Enable filesystem caching for `next build`
|
|
turbopackFileSystemCacheForBuild: true,
|
|
},
|
|
}
|
|
|
|
export default nextConfig
|
|
```
|
|
|
|
```js filename="next.config.js" switcher
|
|
/** @type {import('next').NextConfig} */
|
|
const nextConfig = {
|
|
experimental: {
|
|
// Enable filesystem caching for `next dev`
|
|
turbopackFileSystemCacheForDev: true,
|
|
// Enable filesystem caching for `next build`
|
|
turbopackFileSystemCacheForBuild: true,
|
|
},
|
|
}
|
|
|
|
module.exports = nextConfig
|
|
```
