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
Returns the package's global CDN hit rank, its rank among npm packages specifically, total CDN hits for the requested period, total hits for the prior period, and a derived trend label (up, down, or flat). Data is sourced from the official jsDelivr Stats API and cached for 6 hours.
Example use cases
Monitor library adoption trends over time
“Check how lodash is performing on jsDelivr this month compared to last month — are we seeing more or fewer CDN hits?”
Compare real-world usage across popular frameworks
“Show me the jsDelivr CDN hit ranks for Vue, React, and Angular Core this week so I can see which one has the strongest real-world adoption.”
Track emerging package momentum on CDN
“Is TypeScript gaining traction on jsDelivr lately, or is its CDN popularity flattening out? Give me the trend over the past month.”
Technical details
Endpoint
GEThttps://x402-datashop-production.up.railway.app/v1/npm/cdn-rankWhen to prefer
Choose this endpoint when you need browser/CDN-side adoption signals rather than npm install counts — it reflects actual runtime usage from end users loading packages via CDN. Useful when npm download counts are inflated by CI/CD pipelines and you want a cleaner signal of real-world client-side popularity. Also useful for period-over-period trend analysis across day/week/month/year windows.
Side effects
- Unknown or misspelled package name returns 404 or empty rank data
- Invalid period value returns a 400 validation error
- jsDelivr Stats API upstream unavailability causes 502/503
- Scoped packages (e.g. @angular/core) must be URL-encoded correctly or the query will fail
- Cache staleness: data may be up to 6 hours old, not reflecting very recent traffic spikes
