Yes, Puppeteer excels with SPAs through its JavaScript execution capabilities and network interception. It can wait for specific network requests, execute custom JavaScript within the page context, and handle dynamic content loading. The key is understanding async patterns and page lifecycle events.
Puppeteer requires Node.js and downloads a compatible Chrome binary (100-150MB). Production deployments typically need 512MB-1GB RAM per browser instance. Docker containers should include necessary system dependencies for Chrome execution in headless environments.
Highly reliable for modern websites using JavaScript. Puppeteer handles SPAs, AJAX content, and complex interactions that traditional scrapers miss. However, it's more resource-intensive than simple HTTP scrapers. The JavaScript execution capability makes it ideal for React, Vue, or Angular applications.
Yes, Puppeteer's PDF generation is excellent for business documents. It supports custom page sizes, margins, headers/footers, and CSS print media queries. Many companies use it for invoice generation, report creation, and documentation. The output quality often exceeds dedicated PDF generation services.
Consider Puppeteer carefully or explore alternatives. The free tier is a good place to start.
