# 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:

```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';

(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.
