What problem does it solve?

HTTP GET/HEAD endpoints often re-emit identical responses. This Skill provides HTTP-level caching by emitting ETag headers and validating If-None-Match, enabling conditional requests and reducing bandwidth.

Core Features & Use Cases

  • Emits an ETag header for 2xx responses on GET/HEAD endpoints and returns 304 when If-None-Match matches.
  • Supports a customizable etagResolver to compute a cheap hash from invariant data (e.g., last-modified timestamp, ID).
  • Optional weak validators (W/"hash") to permit semantic equivalence and safe caching with client CDNs.
  • Can be paired with Cache-Control headers to enable true client/CDN caching for read endpoints.

Quick Start

Attach the ETag middleware to GET/HEAD routes and optionally provide a cheap etagResolver or Cache-Control headers to enable client/CDN caching.
