   const puppeteer = require('puppeteer');

   (async () => {
     const browser = await puppeteer.launch();
     const page = await browser.newPage();

     // Perform actions with the page here

     // Close the browser
     await browser.close();
   })();

This code sets up a basic Puppeteer script. It launches a new headless browser instance and creates a new page to work with. 2.

Thepath option specifies the file path where the PDF will be saved, relative to the current working directory. 3.

By navigating to the desired page usingpage.goto() and then callingpage.pdf() with the appropriate options, you can save the page as a PDF file. This feature is useful for scenarios such as generating reports, saving web content for offline viewing, or automating PDF generation from web pages.
