<p>Extends the main <ahref="/next/api/puppeteer.puppeteer">Puppeteer</a> class with Node specific behaviour for fetching and downloading browsers.</p>
<p>If you're using Puppeteer in a Node environment, this is the class you'll get when you run <code>require('puppeteer')</code> (or the equivalent ES <code>import</code>).</p>

<p>The most common method to use is <ahref="/next/api/puppeteer.puppeteernode.launch">launch</a>, which is used to launch and connect to a new browser instance.</p>
<p>See <ahref="/next/api/puppeteer.puppeteer">the main Puppeteer class</a> for methods common to all environments, such as <ahref="/next/api/puppeteer.puppeteer.connect">Puppeteer.connect()</a>.</p>
<p>The constructor for this class is marked as internal. Third-party code should not call the constructor directly or create subclasses that extend the <code>PuppeteerNode</code> class.</p>
