Package Exports
- playwright
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (playwright) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

- Intercept network activity for stubbing and mocking network requests
- Emulate mobile devices, geolocation, permissions
- Native input events for mouse and keyboard

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();
})();
