Should You Do Web Scraping in the Back End? Pros, Cons, and Best Practices or Is It a Good Idea to Do

Web scraping in the back end is fine, but you gotta be ethical. Don’t be that guy who DDoS’s a small site by accident.

Tools:
- Cheerio for Node.js (lightweight).
- Selenium if you need browser automation.
