Page class
Page provides methods to interact with a single tab or [extension background page](https://developer.chrome.com/extensions/background_pages) in Chromium. One [Browser] instance might have multiple [Page] instances.
Signature:
export declare class Page extends EventEmitter
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 Page class.
Example 1
This example creates a page, navigates it to a URL, and then * saves a screenshot:
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 class and will emit various events which are documented in the PageEmittedEvents enum.
Example 2
This example logs a message for a single page load event:
page.once('load', () => console.log('Page loaded!'));
To unsubscribe from events use the off method:
function logRequest(interceptedRequest) {
console.log('A request was made:', interceptedRequest.url());
}
page.on('request', logRequest);
// Sometime later...
page.off('request', logRequest);
