Build Cache

Next.js maintains a Build Cache to speed up the building of your app.

As you build your app for the production server, the compiler will create a Data Cache containing all the results of the fetch() requests, and a Full Route Cache to avoid re-rendering components on-the-fly unnecessarily.

Rebuilding the app won't clear the Data Cache.

Duration

The Build Cache persists across deployments.

Revalidation

To refresh the build cache, remove its directory:

rm .next

Opting Out

You can configure your build scripts (package.json) to clear cache directories or set up cache policies in deployment environments to avoid persistent caching across builds:

"scripts": { "build": "rm -rf .next/cache && next build" }
