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 and saves a screenshot.

import { test } from '@playwright/test';

test('Page Screenshot', async ({ page }) => {
    await page.goto('http://whatsmyuseragent.org/');
    await page.screenshot({ path: `example.png` });
});

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.

import { test, devices } from '@playwright/test';

test.use({
  ...devices['iPhone 13 Pro'],
  locale: 'en-US',
  geolocation: { longitude: 12.492507, latitude: 41.889938 },
  permissions: ['geolocation'],
})

test('Mobile and geolocation', async ({ page }) => {
  await page.goto('https://maps.google.com');
  await page.locator('text="Your location"').click();
  await page.waitForRequest(/.*preview\/pwa/);
  await page.screenshot({ path: 'colosseum-iphone.png' });
});

Evaluate in browser context

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

import { test } from '@playwright/test';

test('Evaluate in browser context', async ({ page }) => {
  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);
});

Intercept network requests

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

import { test } from '@playwright/test';

test('Intercept network requests', async ({ page }) => {
  // Log and continue all network requests
  await page.route('**', route => {
    console.log(route.request().url());
    route.continue();
  });
  await page.goto('http://todomvc.com');
});
