Thanks to tools like Playwright, Puppeteer or Cheerio, it is easy to write Node.js code to extract data from web pages. But eventually things will get complicated. For example, when you try to:
- Perform a deep crawl of an entire website using a persistent queue of URLs.
- Run your scraping code on a list of 100k URLs in a CSV file, without losing any data when your code crashes.
- Rotate proxies to hide your browser origin and keep user-like sessions.
- Disable browser fingerprinting protections used by websites.
