Technical Crawling in Node.js

Why Ditch Traditional Crawlers?

Enterprise website crawlers are powerful but often represent overkill for standard link health and sitemap diagnostics. For standard sites, a simple 100-line script is faster and fully customizable.

The Node.js Solution

By pairing the crawler package with a simple recursive scraper, you can crawl sites, map internal redirect hierarchies, verify status codes, and log missing meta elements to a local CSV.

const Crawler = require('crawler');
const c = new Crawler({
maxConnections: 10,
callback: (error, res, done) => {
if (error) console.error(error);
else {
const $ = res.$;
console.log($('title').text());
}
done();
}
});

Summary

This script executes locally in seconds, logs sitemap loops, and outputs clean CSV report sheets perfectly tailored to your audit pipeline.
