# 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](./puppeteer.knowndevices.md).
|
|
|
|
#### Signature:
|
|
|
|
```typescript
|
|
class Page {
|
|
emulate(device: Device): Promise<void>;
|
|
}
|
|
```
|
|
|
|
## Parameters
|
|
|
|
| Parameter | Type | Description |
|
|
| --------- | ------------------------------- | ----------- |
|
|
| device | [Device](./puppeteer.device.md) | |
|
|
|
|
**Returns:**
|
|
|
|
Promise<void>
|
|
|
|
## Remarks
|
|
|
|
This method is a shortcut for calling two methods: [Page.setUserAgent()](./puppeteer.page.setuseragent.md) and [Page.setViewport()](./puppeteer.page.setviewport.md).
|
|
|
|
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
|
|
|
|
```ts
|
|
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();
|
|
})();
|
|
```
