This adds a new script to calculate docker image size with all parent layers. Note: take this metrics with a grain of salt, since in reality docker compresses and reuses layers. Some historic stats obtained with this script: - **`208MB`** (-33MB) chore(docker): skip "recommended" dependencies (#2917) (1cebf8757c35cebb91c27d16e6b0aa1fcae42fcb) - **`241MB`** (-29MB) chore(docker): trim some of the gstreamer dependencies (#2897) (bce4b1aea95790ebc1f592c44acdea1a1e709fac) - **`272MB`** (-1MB) devops: do cache busting for APT (#2656) (bb3441809541cc6609c5444063973c4ab922981b) - **`273MB`** (+49MB) fix(webkit): update Docker file to include gstreamer (#2636) (5c6c65915c47b8d2f71f5fa75821460183530414) - **`224MB`** (+0MB) chore: fix emojis for CR and FF in Dockerfile (#2522) (24316ad261ca081b6d77dd2f655a42b4836a622b) - **`224MB`** (-1MB) fix: Dockerfile for Firefox (#1937) (b516ac4fb233d30964930d830dea7832a9aae031) - **`225MB`** (+49MB) devops(docker): Install ffmpeg dependency, adding codecs necessary for video playback in Firefox (#1627) (222d01caaadad7419c4e54b4f36a6e9d41d8dc65) - **`176MB`** (+32MB) chore(docs): optionally install XVFB in docker(ec3ee660430336d47a309553981eb960e49c2ede) - **`144MB`** (+144MB) feat: add a playwright-ready docker image (#1161)(1781ae7006554eb77ed42bf90be70ef637fd1aae)

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,
locale: 'en-US',
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();
})();
