☁️ cdnjs Libraries Scraper

🚀 Export the cdnjs front-end catalogue in seconds. Browse, search, or drill into any of 4,000+ open-source JavaScript and CSS libraries hosted on Cloudflare's free CDN, with versions, file lists, SRI hashes, and repository links in one run. No sign-up, no token plumbing, no manual paging.

The cdnjs Libraries Scraper queries the official cdnjs catalogue and returns 13 fields per library, including name, description, latest version, homepage, repository, license, author, keywords, versions, sample file paths, and SRI hashes. cdnjs is a free, fast, and reliable open-source CDN operated by Cloudflare, serving over 200 billion requests per month for front-end developers worldwide.

The catalogue spans 4,000+ libraries including React, Vue, jQuery, Bootstrap, Tailwind, Three.js, D3, Lodash, and thousands more. This Actor streams matching records as CSV, Excel, JSON, or XML in under five minutes. Three run modes (catalogue, search, library) let you sweep the whole catalogue, filter by keyword, or pull a single library with full file listing and per-version SRI hashes.

🎯 Target Audience	💡 Primary Use Cases
Front-end developers, security engineers, build engineers, OSS researchers, technical writers, DevOps teams, marketing analysts	Asset inventories, SRI hash collection, version tracking, dependency discovery, license audits, library popularity research

📋 What the cdnjs Libraries Scraper does

Three run modes in a single Actor:

• 🌐 Catalogue mode. Sweep the entire 4,000+ library catalogue with the most useful metadata fields.
• 🔍 Search mode. Free-text keyword filter (e.g. react, chart, tailwind) across the catalogue.
• 📦 Library mode. Pull a single library with full version history, file list, and per-version SRI hashes.

Each catalogue record includes the library name, description, latest version, homepage, repository, license, author, and keywords. Library mode adds the complete versions array, a sample of hosted files for the latest version, and SRI hashes ready to drop into a <script integrity="..."> attribute.

💡 Why it matters: every front-end stack pulls libraries from cdnjs or a similar CDN. Knowing exactly which versions, files, and hashes are available is the difference between a fast, reproducible build and a broken Subresource Integrity check in production.

📊 Data fields

Each record includes: author, description, fileSamples, homepage, keywords, latestVersion, license, name, repository, scrapedAt, sri, url, versions. These field names come straight from the actor's dataset schema, so what you see here is what lands in your dataset.
