| Page.emulate |
Page.emulate() method
Emulates a given device's metrics and user agent.
To aid emulation, Puppeteer provides a list of known devices that can be via KnownDevices.
Signature:
class Page {
emulate(device: Device): Promise<void>;
}
Parameters
| Parameter | Type | Description |
|---|---|---|
| device | Device |
Returns:
Promise<void>
Remarks
This method will resize the page. A lot of websites don't expect phones to change size, so you should emulate before navigating to the page.
Example
import {KnownDevices} from 'puppeteer';
const iPhone = KnownDevices['iPhone 6'];
(async () => {
const browser = await puppeteer.launch();
const page = await browser.newPage();
await page.emulate(iPhone);
await page.goto('https://www.google.com');
// other actions...
await browser.close();
})();
