PuppeteerNode

PuppeteerNode class

Extends the main Puppeteer class with Node specific behaviour for fetching and downloading browsers.

If you're using Puppeteer in a Node environment, this is the class you'll get when you run require('puppeteer') (or the equivalent ES import).

Signature:

export declare class PuppeteerNode extends Puppeteer

Extends: Puppeteer

Remarks

The most common method to use is launch, which is used to launch and connect to a new browser instance.

See the main Puppeteer class for methods common to all environments, such as Puppeteer.connect().

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

Example

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

import puppeteer from 'puppeteer';

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

Once you have created a page you have access to a large API to interact with the page, navigate, or find certain elements in that page. The `page` documentation lists all the available methods.
