@neshca/cache-handler

Flexible API for replacing the default Next.js cache, enabling custom caching solutions for multi-instance self-hosted deployments.

Latest Release

🎉 Version 1.9.0 has been released! It changes the default estimateExpireAge function to perform the calculation as (staleAge) => staleAge * 1.5 to better align with the default Next.js cache behavior.

This is the final release leading up to version 2.0.0. The upcoming version 2 will bring significant changes and will no longer support Next.js versions 13 and 14. While version 1 will still receive ongoing maintenance, it won't get any new features.

Check out the changelog for more details.

Overview

Welcome to @neshca/cache-handler (pronounced /ˈnæʃkʌ/), a specialized ISR/Data cache API crafted for Next.js applications. This library simplifies configuring shared cache strategies in distributed environments, such as multiple, independent application instances. It offers a flexible and easy-to-integrate solution for custom cache strategies, especially for Redis.

Features

• Shared Cache for Distributed Environments: Perfect for self-hosted deployments with multiple application instances.
• Easy Customization: Provides a straightforward API with pre-configured Handlers.
• On-Demand Revalidation: Simplifies revalidation across all application replicas.
• TTL Management: Automatic cache cleanup to keep storage space efficient.
• Support for Next.js Routers: Full support and one setup for the Pages and the App Router.
• neshCache Function: Utilize the neshCache ↗ function to replace unstable_cache for more control over caching.
• neshClassicCache Function: Use the CacheHandler in the Pages Router to cache the result of expensive operations in the getServerSideProps and API routes.
• Pre-populate the Cache with Initial Data: Automatically pre-populate the cache with the initial data when the application starts using the instrumentation hook ↗.
