Getting started

Puppeteer will be familiar to people using other browser testing frameworks. You launch/connect a browser, create some pages, and then manipulate them with Puppeteer's API.

The following example searches developer.chrome.com for blog posts with text "automate beyond recorder", click on the first result and print the full title of the blog post.

import puppeteer from 'puppeteer';

(async () => {
  // 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
  await page.type('.devsite-search-field', 'automate beyond recorder');

  // Wait and click on first result
  const searchResultSelector = '.devsite-result-item-link';
  await page.waitForSelector(searchResultSelector);
  await page.click(searchResultSelector);

  // Locate the full title with a unique string
  const textSelector = await page.waitForSelector(
    'text/Customize and automate'
  );
  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();
})();
