Web scraping with Node and Cheerio
Tired of manually copy-pasting data? Let’s automate it.
Over my 8 years of building backend systems and scrapers, I've found that turning the static web into actionable data is an absolute superpower. In my latest video, I break down how to build a custom, multi-page web scraper from scratch using Node.js.
We scrape Hacker News job listings, filter for specific roles, and automatically output a clean, timestamped CSV.
The Stack & Process:
Axios: Fetching the raw HTML.
Cheerio: Parsing the DOM to extract titles, links, and dates.
Recursion: Automatically handling pagination to jump from page to page.
CSV/Moment: Generating the final structured dataset.
