# Page.emulateNetworkConditions() method
|
|
|
|
This does not affect WebSockets and WebRTC PeerConnections (see https://crbug.com/563644). To set the page offline, you can use [Page.setOfflineMode()](./puppeteer.page.setofflinemode.md).
|
|
|
|
A list of predefined network conditions can be used by importing [PredefinedNetworkConditions](./puppeteer.predefinednetworkconditions.md).
|
|
|
|
#### Signature:
|
|
|
|
```typescript
|
|
class Page {
|
|
abstract emulateNetworkConditions(
|
|
networkConditions: NetworkConditions | null
|
|
): Promise<void>;
|
|
}
|
|
```
|
|
|
|
## Parameters
|

|
|
<table><thead><tr><th>

<tbody><tr><td>

networkConditions
|
|
|
|
</td><td>
|
|
|
|
[NetworkConditions](./puppeteer.networkconditions.md) \| null
|
|
|
|
</td><td>
|
|
|
|
Passing `null` disables network condition emulation.
|
|
|
|
</td></tr>
|
|
</tbody></table>
|
|
**Returns:**
|
|
|
|
Promise<void>
|
|
|
|
## Example
|
|
|
|
```ts
|
|
import {PredefinedNetworkConditions} from 'puppeteer';
|
|
const slow3G = PredefinedNetworkConditions['Slow 3G'];
|
|
|
|
(async () => {
|
|
const browser = await puppeteer.launch();
|
|
const page = await browser.newPage();
|
|
await page.emulateNetworkConditions(slow3G);
|
|
await page.goto('https://www.google.com');
|
|
// other actions...
|
|
await browser.close();
|
|
})();
|
|
```
