## What it is
node-crawler is a TypeScript web crawler/spider library for Node.js that fetches pages and provides server-side DOM parsing with automatic jQuery-style manipulation via Cheerio. It offers a configurable request pool, retries, rate limiting, priority queues, and charset detection.

## Use cases
- scrape product prices from e-commerce sites
- crawl a website and extract links
- parse html pages with jquery-like selectors in node
- build a polite crawler with rate limiting and retries
- extract data from web pages into structured output
- queue large-scale crawling jobs with priority

## When to choose
- you need server-side DOM traversal with Cheerio/jQuery syntax
- you want built-in rate limiting, retries, and a priority queue
- you're on Node.js 22+ and comfortable with ESM
- you need charset detection and conversion handled automatically

## When to avoid
- you need to render JavaScript-heavy SPA pages (use Puppeteer/Playwright instead)
- you want a simple one-off HTTP fetch without crawling features
- you're on an older Node.js version below 22

## Facets
- artifact type: library
