# PuppeteerNode class
Extends the main [Puppeteer](./puppeteer.puppeteer.md) class with Node specific behaviour for fetching and downloading browsers.
If you're using Puppeteer in a Node environment, this is the class you'll get when you run `require('puppeteer')` (or the equivalent ES `import`).
#### Signature:
2022-07-05 13:41:43 +00:00
```typescript
export declare class PuppeteerNode extends Puppeteer
```
**Extends:** [Puppeteer](./puppeteer.puppeteer.md)
## Remarks
The most common method to use is [launch](./puppeteer.puppeteernode.launch.md), which is used to launch and connect to a new browser instance.
See [the main Puppeteer class](./puppeteer.puppeteer.md) for methods common to all environments, such as [Puppeteer.connect()](./puppeteer.puppeteer.connect.md).
The constructor for this class is marked as internal. Third-party code should not call the constructor directly or create subclasses that extend the `PuppeteerNode` class.
## Example
The following is a typical example of using Puppeteer to drive automation:
```ts
import puppeteer from 'puppeteer';
2022-07-05 13:41:43 +00:00
(async () => {
const browser = await puppeteer.launch();
const page = await browser.newPage();
await page.goto('https://www.google.com');
// other actions...
await browser.close();
})();
```
Once you have created a `page` you have access to a large API to interact with the page, navigate, or find certain elements in that page. The [\`page\` documentation](./puppeteer.page.md) lists all the available methods.
