Web Scraping with Puppeteer and NodeJS
summary
Demonstrates concrete Puppeteer recipes: take a full-page screenshot in five or six lines of code, open Chromium headless or headful with headless=false, scrape speaker names by running page.evaluate and querySelectorAll to return an array, generate PDFs with standard formats like A4, and drive interactions (type, click, paginate) to scrape Amazon search results. Notes a limitation: Chromium lacks speech synthesis so use Chrome Canary and set executablePath, and the demos run end to end successfully.
