Overview

Typed, hierarchical, framework-agnostic tagged-cache for server-side caching.

For the canonical reference, see the README on GitHub.

What it solves

Server-side caches benefit from invalidation by tag — Next.js's revalidateTag, Cloudflare's Cache-Tag header, and similar primitives across platforms. Without a shared abstraction, every call site ends up hand-rolling tag strings like shopify.${shop.id}.product.${handle}, and every webhook handler ends up hand-rolling the matching fanout. Typos break invalidation silently.

tagtree declares the tag shape once as a typed schema, then generates builders, invalidators, and a plugin contract from it. Emitters and invalidators talk to the same schema — string concatenation disappears from user code.
