Browser Automation Tools: Puppeteer vs Selenium WebDriver
Both Puppeteer and Selenium WebDriver are tools that help developers control web browsers through code. They're commonly used for automated testing, taking screenshots, and scraping web content. While Puppeteer works specifically with Chrome/Chromium browsers and is made by Google, Selenium WebDriver supports multiple browsers like Chrome, Firefox, and Safari.

Code Examples
Puppeteer Example: Launching a Browser
1const puppeteer = require('puppeteer');
2(async () => {
3 const browser = await puppeteer.launch();
4 const page = await browser.newPage();
5 await page.goto('https://example.com');
6 await browser.close();
7})();This code launches a headless Chrome browser using Puppeteer, navigates to a webpage, and then closes the browser.
Selenium WebDriver Example: Launching a Browser
1const { Builder, By, Key, until } = require('selenium-webdriver');
2(async function example() {
3 let driver = await new Builder().forBrowser('chrome').build();
4 await driver.get('https://example.com');
5 await driver.quit();
6})();This code launches a Chrome browser using Selenium WebDriver, navigates to a webpage, and then closes the browser.
Recommendation
Summary
Puppeteer is a faster and more efficient option for automating Chrome, while Selenium WebDriver provides more flexibility and compatibility with multiple browsers.
Details
- Puppeteer is ideal for automating Chrome-specific tasks, such as web scraping or browser automation.
- Selenium WebDriver is better suited for cross-browser testing and automation.

Installation
npm i puppeteer # Downloads compatible Chrome during installation. npm i puppeteer-core # Alternatively, install as a library, without downloading Chrome.
Example
import puppeteer from 'puppeteer'; // Or import puppeteer from 'puppeteer-core'; // Launch the browser and open a new blank page const browser = await puppeteer.launch(); const page = await browser.newPage(); // Navigate the page to a URL. await page.goto('https://developer.chrome.com/'); // Set screen size. await page.setViewport({width: 1080, height: 1024}); // Type into search box using accessible input name. await page.locator('aria/Search').fill('automate beyond recorder'); // Wait and click on first result. await page.locator('.devsite-result-item-link').click(); // Locate the full title with a unique string. const textSelector = await page .locator('text/Customize and automate') .waitHandle(); const fullTitle = await textSelector?.evaluate(el => el.textContent); // Print the full title. console.log('The title of this blog post is "%s".', fullTitle); await browser.close();
