Next.js Cache Handler package now available

The @pantheon-systems/nextjs-cache-handler package is now publicly available. It enables persistent caching on Pantheon's Next.js platform, so your cached data survives across deployments and server restarts.

Features

• Works out of the box on Pantheon — The handler auto-detects your environment. No extra configuration needed beyond installing the handler in your Next.js application.
• Full support for Next.js caching APIs — revalidateTag(), revalidatePath(), and ISR work as expected, including automatic CDN cache invalidation so your visitors see updates immediately.
• Next.js 16 use cache support — Compatible with the new cacheHandlers API and 'use cache' directive introduced in Next.js 16.
• Smart build deploys — When you deploy a new build, page caches refresh automatically while your data caches are preserved, avoiding unnecessary re-fetches from APIs and databases.
• Local development friendly — Uses file-based caching in development so you can test caching behavior locally without any cloud dependencies.
• Debug logging — Set CACHE_DEBUG=true to see detailed cache hit/miss/set activity for troubleshooting.

Getting started

Install the package:

Then configure your Next.js application to use the cache handler. For full setup instructions, usage examples, and configuration options, see the README on GitHub.
