How this service works
Real browser-side adoption signal from the official jsDelivr Stats API: global CDN hit rank, rank within npm, total hits over the period, previous-period comparison and a derived trend (up/down/flat, lower rank = more popular). Query: ?pkg=react&period=week (period: day, week, month, year). Complements npm download counts; cached 6h.
Output
A JSON object containing the package's current CDN rank, previous rank, trend direction (up/down/stable), total CDN hits for the period, previous period's hits, type-specific rank, the time period queried, and the data source (jsDelivr).
Example use cases
Example prompt
“What's the current weekly CDN rank for the 'react' npm package on jsDelivr — is it trending up or down compared to last week?”
Technical details
Endpoint
GEThttps://data.greeneris.io/v1/npm/cdn-rankWhen to prefer
Use this endpoint when you need to assess the relative popularity or CDN adoption of a specific npm package using jsDelivr delivery statistics. Ideal for comparing library traction, monitoring if a package is gaining or losing momentum, or making dependency decisions based on community adoption signals.
Side effects
- Unknown or misspelled package name returns empty or error response
- Package has no CDN traffic and may not appear in rankings
- Invalid period enum value causes request rejection
- Network timeout if jsDelivr upstream data is temporarily unavailable
