npm Package Scraper — Metadata & Download Stats

Scrape npm package data — versions, license, repository, dependencies, maintainers, and download counts — into one unified dataset using the public npm registry API. No login, no proxies, no browser, no API key.

Search the registry by keyword, or fetch exact package names (scoped names like @types/node too).

What you get

Every package is one row (recordType: "package"):

Field	Description
name	package name
version	latest published version
description	package description
license	SPDX license (e.g. MIT)
homepage / repository	homepage and cleaned repo URL
author	author name
keywords	list of keywords
dependenciesCount	number of runtime dependencies
maintainersCount	number of maintainers
createdAt / modifiedAt / latestPublishedAt	ISO timestamps
downloads / downloadsPeriod	downloads over the chosen window
url	npmjs.com package page
