## [Documentation](https://playwright.dev) | [API reference](https://playwright.dev/docs/api/class-playwright/)

Playwright is a Node.js library to automate [Chromium](https://www.chromium.org/Home), [Firefox](https://www.mozilla.org/en-US/firefox/new/) and [WebKit](https://webkit.org/) with a single API. Playwright is built to enable cross-browser web automation that is **ever-green**, **capable**, **reliable** and **fast**.

Headless execution is supported for all the browsers on all platforms. Check out [system requirements](https://playwright.dev/docs/intro/#system-requirements) for details.

## 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.

* [Installation configuration](https://playwright.dev/docs/installation)
* [API reference](https://playwright.dev/docs/api/class-playwright)

## 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.

```js
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.

```js
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.

```js
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.

```js
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();
})();
```
