What is puppeteer?

Puppeteer is a Node library which provides a high-level API to control Chrome or Chromium over the DevTools Protocol. It is primarily used for automating web browser actions, such as taking screenshots, generating pre-rendered content, and automating form submissions, among other things.

What are puppeteer's main functionalities?

Web Scraping

Puppeteer can be used to scrape content from web pages by programmatically navigating to the page and extracting the required data.

const puppeteer = require('puppeteer');

(async () => {
  const browser = await puppeteer.launch();
  const page = await browser.newPage();
  await page.goto('https://example.com');
  const data = await page.evaluate(() => document.querySelector('*').outerHTML);
  console.log(data);
  await browser.close();
})();

Automated Testing

Puppeteer can automate form submissions and simulate user actions for testing web applications.

const puppeteer = require('puppeteer');

(async () => {
  const browser = await puppeteer.launch();
  const page = await browser.newPage();
  await page.goto('https://example.com/login');
  await page.type('#username', 'user');
  await page.type('#password', 'pass');
  await page.click('#submit');
  // Check for successful login
  await page.waitForSelector('#logout');
  await browser.close();
})();

PDF Generation

Puppeteer can generate PDFs from web pages, which is useful for creating reports, invoices, and other printable documents.

const puppeteer = require('puppeteer');

(async () => {
  const browser = await puppeteer.launch();
  const page = await browser.newPage();
  await page.goto('https://example.com', {waitUntil: 'networkidle2'});
  await page.pdf({path: 'example.pdf', format: 'A4'});
  await browser.close();
})();

Screenshot Capture

Puppeteer can take screenshots of web pages, either of the full page or specific elements, which is useful for capturing the state of a page for documentation or testing.

const puppeteer = require('puppeteer');

(async () => {
  const browser = await puppeteer.launch();
  const page = await browser.newPage();
  await page.goto('https://example.com');
  await page.screenshot({path: 'example.png'});
  await browser.close();
})();
