## Puppeteer class
|
||
|
|
|
||
|
|
The main Puppeteer class.
|
||
|
|
|
||
|
|
IMPORTANT: if you are using Puppeteer in a Node environment, you will get an instance of [PuppeteerNode](./puppeteer.puppeteernode.md) when you import or require `puppeteer`. That class extends `Puppeteer`, so has all the methods documented below as well as all that are defined on [PuppeteerNode](./puppeteer.puppeteernode.md).
|
||
|
|
|
||
|
|
<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.
