npm Registry Package Scraper

What it does

Searches the npm registry for JavaScript and Node.js packages matching a query and extracts package metadata including name, version, description, publish date, publisher, and links.

This Apify actor automates the collection of data from a public API, extracting structured information and saving it directly into an Apify dataset. It handles pagination automatically, supports configurable result limits, and includes robust error handling with timeouts on all HTTP requests. The actor is designed for reliability: it validates inputs, applies sensible defaults, and produces a fallback record when no results are found, so your downstream workflows never receive an empty dataset.

Why use it

Manually collecting data from web APIs is tedious and error-prone. This actor eliminates that burden by running in the cloud on the Apify platform, where it can be scheduled, integrated with webhooks, or chained with other actors. Whether you are conducting market research, building a knowledge base, monitoring package ecosystems, or feeding data into an analytics pipeline, this actor gives you structured, ready-to-use JSON output with zero browser overhead. It uses lightweight HTTP requests instead of a full browser, which makes it fast and cost-effective.

Input parameters

Parameter	Type	Required	Default	Description
searchQuery	string	Yes	"web scraping"	The search term to use when querying the API.
maxResults	integer	No	100	Maximum number of results to return (1 to 1000).

Output data

Each item in the output dataset contains the following fields:

• name - The npm package name.
• version - Latest published version string.
• description - Short package description.
• publishDate - ISO date of last publish.
• publisher - npm username of the publisher.
• npmUrl - Direct URL to the npm package page.
• keywords - Comma-separated list of package keywords.

All string fields are null-checked; missing values are stored as null rather than undefined.

Example output

{
    "name": "crawlee",
    "version": "3.11.5",
    "description": "A web scraping and browser automation library",
    "publishDate": "2024-01-15T10:30:00.000Z",
    "publisher": "apify",
    "npmUrl": "https://www.npmjs.com/package/crawlee",
    "keywords": "scraping, crawling, automation"
}

Pricing

This actor is priced on a usage basis:

• $0.01 per result returned in the dataset.
• $0.005 per actor start (fixed platform fee).

For example, scraping 500 results would cost approximately $5.005. Apify provides free monthly credits for new users, so you can try the actor at no charge.
