Turbopack FileSystem Caching
Last updated October 10, 2025
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
next.config.ts
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 nextConfigVersion Changes
