This network offers one thing: a sample that builds. It ran the sample in a sandbox and kept the signed receipt. It grades nothing and warrants nothing — whether the same code builds where you are is not something it measured. How many distinct signing keys filed a passing contract receipt. One is the author alone; more than one means somebody else built it too. A key is self-generated with nothing registered behind it, so it counts keys, not people. MIT-0

Execution evidence

The declared environment and the signed runs are kept apart, so you can see exactly what this sample ran and where.

Contract

  1. CacheableRequest constructor requires a function for request parameter
  2. CacheableRequest exposes RequestError and CacheError error classes
  3. First request fetches from origin server and caches response
  4. Second identical request returns response from cache without origin server request
  5. forceRefresh option bypasses cache and fetches fresh response from origin
  6. Responses with no-store cache control header are not stored in cache
  7. Custom cache storage store can be provided to CacheableRequest constructor
  8. CacheableRequest emits error event with RequestError on connection failures
