Reactive state for the backend
summary
Claims that dynamic pages serve at static speed while removing manual cache ops by using useCache and revalidateTag. Demonstrates a Convex setup where a wrapper hashes function name+args into a cache key, starts a Convex subscription or CMS webhook, and posts that key to revalidateTag on changes. Shows a demo where server-rendered pages stop flashing stale content and layout shifts disappear. Mentions support for updateTag, custom cache handlers, per-query cacheLife (examples used: weeks) and large sites with millions of pages.
