Signature: ```typescript export declare class Page extends EventEmitter ``` Extends: [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); ``` ## Properties | Property | Modifiers | Type | Description | | --- | --- | --- | --- | | [accessibility](./puppeteer.page.accessibility.md) | | [Accessibility](./puppeteer.accessibility.md) | | | [coverage](./puppeteer.page.coverage.md) | | [Coverage](./puppeteer.coverage.md) | | | [keyboard](./puppeteer.page.keyboard.md) | | [Keyboard](./puppeteer.keyboard.md) | | | [mouse](./puppeteer.page.mouse.md) | | [Mouse](./puppeteer.mouse.md) | | | [touchscreen](./puppeteer.page.touchscreen.md) | | [Touchscreen](./puppeteer.touchscreen.md) | | | [tracing](./puppeteer.page.tracing.md) | | [Tracing](./puppeteer.tracing.md) | | ## Methods | Method | Modifiers | Description | | --- | --- | --- | | [$(selector)](./puppeteer.page._.md) | | Runs document.querySelector within the page.
