## Page class

Page provides methods to interact with a single tab or [extension background page](https://developer.chrome.com/extensions/background_pages) in Chromium.

<b>Signature:</b>

```typescript
export declare class Page extends EventEmitter 
```
<b>Extends:</b> [EventEmitter](./puppeteer.eventemitter.md)

## Remarks

One Browser instance might have multiple Page instances.

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

## Example 1

This example creates a page, navigates it to a URL, and then \* saves a screenshot:

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

(async () => {
  const browser = await puppeteer.launch();
  const page = await browser.newPage();
  await page.goto('https://example.com');
  await page.screenshot({path: 'screenshot.png'});
  await browser.close();
})();

```
The Page class extends from Puppeteer's [EventEmitter](./puppeteer.eventemitter.md) class and will emit various events which are documented in the [PageEmittedEvents](./puppeteer.pageemittedevents.md) enum.

## Example 2

This example logs a message for a single page `load` event:

```js
page.once('load', () => console.log('Page loaded!'));

```
To unsubscribe from events use the `off` method:

```js
function logRequest(interceptedRequest) {
  console.log('A request was made:', interceptedRequest.url());
}
page.on('request', logRequest);
// Sometime later...
page.off('request', logRequest);

```

## Methods

|  Method | Modifiers | Description |
|  --- | --- | --- |
|  [$(selector)](./puppeteer.page._.md) |  | Runs <code>document.querySelector</code> within the page. If no element matches the selector, the return value resolves to <code>null</code>. |
