NPM Package Stats Scraper

Web & SEO Tools

Operated by Sourcelane✓ verified

A scraper that extracts comprehensive npm package metadata and metrics for one or many packages: package identity and description, license and homepage, repository and issue tracker URLs, keywords and author/maintainer information, full dependency tree (including runtime, dev, and peer dependencies) and total dependency count, version history and counts, first and last publish timestamps, deprecation notices, TypeScript types entry and main/module entries, engines requirements, and download metrics aggregated over configurable recent windows (24h, 7d, 30d). Technical capabilities include bulk processing of package lists, parallel fetching to increase throughput, and production of structured records containing both static metadata and time-windowed popularity metrics suitable for downstream analysis.
