Headless execution is supported for all the browsers on all platforms.

Usage

npm i -D playwright

This installs Playwright and browser binaries for Chromium, Firefox and WebKit. Once installed, you can

require

Playwright in a Node.js script and automate web browser interactions.

Capabilities

Playwright is built to automate the broad and growing set of web browser capabilities used by Single Page Apps and Progressive Web Apps.

  • Scenarios that span multiple page, domains and iframes
  • Auto-wait for elements to be ready before executing actions (like click, fill)
  • Intercept network activity for stubbing and mocking network requests
  • Emulate mobile devices, geolocation, permissions
  • Support for web components via shadow-piercing selectors
  • Native input events for mouse and keyboard
  • Upload and download files

Examples

Page screenshot

This code snippet navigates to whatsmyuseragent.org in Chromium, Firefox and WebKit, and saves 3 screenshots.

const playwright = require('playwright'); (async () =\> { for (const browserType of ['chromium', 'firefox', 'webkit']) { const browser = await playwright[browserType].launch(); const context = await browser.newContext(); const page = await context.newPage(); await page.goto('http://whatsmyuseragent.org/'); await page.screenshot({ path: `example-${browserType}.png` }); await browser.close(); } })();

Mobile and geolocation

This snippet emulates Mobile Safari on a device at a given geolocation, navigates to maps.google.com, performs action and takes a screenshot.

const { webkit, devices } = require('playwright'); const iPhone11 = devices['iPhone 11 Pro']; (async () =\> { const browser = await webkit.launch(); const context = await browser.newContext({ ...iPhone11, geolocation: { longitude: 12.492507, latitude: 41.889938 }, permissions: ['geolocation'] }); const page = await context.newPage(); await page.goto('https://maps.google.com'); await page.click('text="Your location"'); await page.waitForRequest(/.\*preview\/pwa/); await page.screenshot({ path: 'colosseum-iphone.png' }); await browser.close(); })();

Evaluate in browser context

This code snippet navigates to example.com in Firefox, and executes a script in the page context.

const { firefox } = require('playwright'); (async () =\> { const browser = await firefox.launch(); const context = await browser.newContext(); const page = await context.newPage(); await page.goto('https://www.example.com/'); const dimensions = await page.evaluate(() =\> { return { width: document.documentElement.clientWidth, height: document.documentElement.clientHeight, deviceScaleFactor: window.devicePixelRatio } }); console.log(dimensions); await browser.close(); })();

Intercept network requests

This code snippet sets up request routing for a WebKit page to log all network requests.

const { webkit } = require('playwright'); (async () =\> { const browser = await webkit.launch(); const context = await browser.newContext(); const page = await context.newPage(); // Log and continue all network requests page.route('\*\*', route =\> { console.log(route.request().url()); route.continue(); }); await page.goto('http://todomvc.com'); await browser.close(); })();
