How to Build a Reliable JavaScript Web Scraper with LLM Integration? or Best Practices for Using a Ja

If you’re dealing with heavy JS sites, forget Cheerio. Puppeteer + LLM is the way.

But speed is a trade-off. I use a hybrid approach: Puppeteer for rendering, then Cheerio for static parts. Saves some time.

For rate limits, residential proxies are worth the $$$. Also, set a max retry limit—don’t piss off the site admins.

Cool trick: Use LLM to generate XPath selectors dynamically. Saves hours of manual tweaking.
