  1. Launching puppeteer browser

    const browser = await puppeteer.launch({
  headless: false,
  defaultViewport: null,
  args: ["--start-maximized"],
});

  2. Launching your own browser

    const browser = await puppeteer.launch({
  executablePath:
    "/Applications/Google Chrome.app/Contents/MacOS/Google Chrome",
  headless: false,
  defaultViewport: null, // This allows the browser to open in full screen
  args: ["--start-fullscreen"], // Full screen argument
});

Opening new page

const page = await browser.newPage();
await page.goto("https://www.geeksforgeeks.org/problem-of-the-day");

Click On link and get new page

// Listen for new target (tab) creation
const [newPage] = await Promise.all([
  new Promise((resolve) =>
    browser.once("targetcreated", (target) => resolve(target.page()))
  ),
  page.click(".ui.button.problemOfTheDay_POTDCntBtn__SSQfX"),
]);

Type on a input box

await newPage.waitForSelector(".next_input");
const inputbox = await newPage.$$(".next_input");
await inputbox[0].type("harshsharma20503");
await inputbox[1].type("H@rsh123sharma");
await newPage.click(".notSocialLoginBtnText");

const hrefs = await page.evaluate(() => {
  // Select all <a> tags on the page
  const anchorTags = document.querySelectorAll("a");

  // Extract and return the href attributes from all <a> tags
  return Array.from(anchorTags)
    .map((a) => a.href)
    .filter((href) => href)
    .filter((href) => href.includes("envType=daily-question"));
});
