## Puppeteer class

The main Puppeteer class. Provides the [launch](./puppeteer.puppeteer.launch.md) method to launch a browser.

When you `require` or `import` the Puppeteer npm package you get back an instance of this class.

<b>Signature:</b>

```typescript
export declare class Puppeteer 
```

## Remarks

The constructor for this class is marked as internal. Third-party code should not call the constructor directly or create subclasses that extend the `Puppeteer` class.

## Example

The following is a typical example of using Puppeteer to drive automation:

```js
const puppeteer = require('puppeteer');

(async () => {
  const browser = await puppeteer.launch();
  const page = await browser.newPage();
  await page.goto('https://www.google.com');
  // other actions...
  await browser.close();
})();

```
