This free crash course gets straight into code – no long theory section before you start scraping. You'll use Node.js alongside Puppeteer (Google's headless browser tool), Cheerio, Request, and NightmareJs to pull structured data from real websites.

What you'll be able to do

  • Build scrapers from scratch and choose the right tool for a given site
  • Automate user interactions with Puppeteer
  • Scrape with the native Request and Cheerio libraries
  • Explore alternative approaches using NightmareJs

You'll want working knowledge of ES6 JavaScript plus basic CSS and jQuery selectors going in. From there, the course leans on real-world examples and genuine problem-solving rather than toy demos, so by the end you can build your own scraper with confidence.

Udemy thumbnail

Udemy is the largest open marketplace for online courses on the internet. Founded in 2010 by Eren Bali, Oktay Caglar, and Gagan Biyani and headquartered in San Francisco, the company went public on the Nasdaq in 2021 under the ticker UDMY. The platform hosts well over two hundred thousand courses across software development, IT and cloud, data science, design, business, marketing, and creative skills, taught by tens of thousands of independent instructors. Roughly seventy million learners use it worldwide, and the corporate arm — Udemy Business — supplies a curated subset of that catalog to enterprise customers.

Because Udemy is a marketplace rather than a single editorial publisher, the catalog is uneven by design. The strongest material lives in the long-form, project-based courses authored by working engineers — full-stack JavaScript, React, Node.js, Python data science, AWS, Docker and Kubernetes, mobile development with Flutter and React Native, and cloud certification preparation. The CourseFlix listing under this source is the slice of that catalog that has been mirrored here for offline-friendly viewing, organized by topic and updated as new releases land. Pricing on Udemy itself swings dramatically with the site's near-permanent sales, which is why the platform is best treated as a deep reference catalog: pick instructors with strong reviews and a track record of updating their material rather than buying on the headline price alone.
