(async () => {
const browser = await puppeteer.launch();
const page = await browser.newPage();
await page.goto('https://example.com');
const title = await page.title();
console.log('Page title:', title);
await browser.close();
})();
The API follows intuitive naming conventions and requires fewer configuration options for basic operations.

await page.setUserAgent('Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36');
await page.setViewport({ width: 1366, height: 768 });
await page.evaluateOnNewDocument(() => {
Object.defineProperty(navigator, 'webdriver', {
get: () => undefined,
});
});
Handling Dynamic Content
When working with JavaScript-heavy applications, handling AJAX requests using Puppeteer becomes crucial for successful data extraction.
8. Better Error Handling and Debugging
Puppeteer provides more detailed error messages and debugging information:
// Enhanced error context
try {
await page.waitForSelector('.dynamic-content', { timeout: 5000 });

10. Specialized Use Cases Where Puppeteer Excels
PDF Generation
// Superior PDF generation capabilities
await page.pdf({
path: 'document.pdf',
format: 'A4',
printBackground: true,
margin: { top: '20px', bottom: '20px' }
});
Screenshot Generation
// Advanced screenshot options
await page.screenshot({
path: 'screenshot.png',
fullPage: true,
clip: { x: 0, y: 0, width: 1200, height: 800 }
});
Performance Comparison
Here's a practical comparison showing Puppeteer's performance advantages:
// Puppeteer - optimized for speed
const puppeteer = require('puppeteer');
async function performanceScraping() {
const browser = await puppeteer.launch({
args: ['--no-sandbox', '--disable-setuid-sandbox', '--disable-dev-shm-usage']
});
const page = await browser.newPage();
// Disable unnecessary resources for faster loading
await page.setRequestInterception(true);
page.on('request', (req) => {
if(req.resourceType() === 'stylesheet' || req.resourceType() === 'image'){
req.abort();
} else {
req.continue();
}
});
const startTime = Date.now();
await page.goto('https://example.com');
const loadTime = Date.now() - startTime;
console.log(`Page loaded in ${loadTime}ms`);
await browser.close();
}
Practical Implementation Example
Here's a complete example demonstrating Puppeteer's advantages in a real web scraping scenario:
const puppeteer = require('puppeteer');
async function scrapeWithPuppeteer(url) {
const browser = await puppeteer.launch({
headless: true,
args: ['--no-sandbox', '--disable-setuid-sandbox']
});
const page = await browser.newPage();
// Set realistic browser behavior
await page.setUserAgent('Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36');
await page.setViewport({ width: 1366, height: 768 });
try {
await page.goto(url, { waitUntil: 'networkidle2' });
// Wait for dynamic content to load
await page.waitForSelector('.content', { timeout: 10000 });
// Extract data
const data = await page.evaluate(() => {
return Array.from(document.querySelectorAll('.item')).map(item => ({
title: item.querySelector('.title')?.textContent?.trim(),
price: item.querySelector('.price')?.textContent?.trim(),
link: item.querySelector('a')?.href
}));
});
return data;
} finally {
await browser.close();
}
}
// Usage example
scrapeWithPuppeteer('https://example-store.com/products')
.then(data => console.log('Scraped data:', data))
.catch(error => console.error('Scraping failed:', error));
Advanced Use Cases
Handling Complex JavaScript Applications
# For Python developers, here's equivalent functionality using pyppeteer
import asyncio
from pyppeteer import launch
async def scrape_spa():
browser = await launch()
page = await browser.newPage()
await page.goto('https://spa-example.com')
await page.waitForSelector('.loaded-content')
# Extract data after JavaScript execution
content = await page.evaluate('() => document.body.innerText')
await browser.close()
return content
# Run the async function
result = asyncio.get_event_loop().run_until_complete(scrape_spa())
