runtime-cache

You can implement ephemeral caching using a region-specific key-value store that persists across Vercel deployments but expires after a set period. This approach stores computed data or API responses with a specific TTL and associated tags.

Yes, tag-based cache invalidation is supported in serverless environments to provide fine-grained control over your cache. You assign tags to cached entries and selectively invalidate them when underlying data changes.

Runtime caching is framework-agnostic and works with any framework that integrates with Vercel Functions. It relies on the @vercel/functions library to manage caching across Functions, Routing Middleware, and Builds.

The best way to cache API responses in Vercel serverless applications is using an ephemeral key-value store with tag-based invalidation. This reduces database load and improves application performance by caching computed data.

Yes, you need the @vercel/functions library to integrate serverless caching within your application. This dependency is required to manage the ephemeral, region-specific key-value store across Vercel Functions.
