# jsDelivr npm package stats

Inputs: (none — replays green as-is; see the personalization note)

<!--
  Personalization: swap the literal `react` at the end of the URL for your

  Why an agent would replay this: jsDelivr's data API mirrors npm's tag and
  version list from a CDN's point of view — a useful cross-check that a
  package is resolvable through the CDN path, not just the registry.
  Read-only, no auth.

  Endpoint verified live on 2026-07-22: 200, tags.latest a semver string,
  versions a non-empty array.

The assertions pin shape, not the exact version — a new React release
should not break this replay.

- assert: json.versions is array
- bind: latest = json.tags.latest
- effect: read
