What is puppeteer?

Puppeteer is a Node library which provides a high-level API to control headless Chrome or Chromium over the DevTools Protocol. You can do all things automatically which you are doing on the browser manually.

Generate screenshots and PDFs of pages
Crawl a website
Create an up-to-date, automated testing environment. Run your tests directly in the latest version of Chrome using the latest JavaScript and browser features

Load chrome extensions



const puppeteer = require('puppeteer');

(async () => {
  const customArgs = [
    `--start-maximized`,
    `--load-extension=${process.env.extdarkreader}`
  ];
  const browser = await puppeteer.launch({
    defaultViewport: null,
    executablePath:process.env.chrome,
    headless: false,
    ignoreDefaultArgs: ["--disable-extensions","--enable-automation"],
    args: customArgs,
  });
  const page = await browser.newPage();
  await page.goto(`https://dev.to/`);
  await page.waitForNavigation();
  await page.close();
  await browser.close();
})();

By default, some functionalities are disabled in puppeteer so you can enable by assigning few arguments in ignoreDefaultArgs.



 ignoreDefaultArgs: ["--disable-extensions"]

ignoreDefaultArgs : > If true, then do not use puppeteer.defaultArgs(). If an array is given, then filter out the given default arguments. Dangerous option; use with care. Defaults to false.

After running above code got a dark theme of website https://dev.to
