How to open an empty tab in non-headless mode using Puppeteer?

When using Puppeteer for browser automation, the browser runs by default in headless mode, meaning it has no graphical interface. If you need to open a blank tab in non-headless mode, you can follow these steps:

1. Set the browser to non-headless mode: When launching Puppeteer, set the headless option to false. This allows the browser to run with a graphical interface.

2. Open a new blank tab: Use Puppeteer's API to create a new browser page.

Here is a specific code example:

javascript
const puppeteer = require('puppeteer');

(async () => {
    // Launch browser in non-headless mode
    const browser = await puppeteer.launch({
        headless: false // Set to false to display the browser interface
    });

    // Open a new blank page
    const page = await browser.newPage();

    // Navigate to a blank page
    await page.goto('about:blank');

    // You can add more operations here, such as taking screenshots or analyzing page content

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

In this example, first, launch a non-headless browser instance using puppeteer.launch() with headless: false. Then, create a new page using browser.newPage(). Next, navigate to a blank page using page.goto('about:blank'). Finally, close the browser after completing the required operations.

Using non-headless mode provides the benefit of visually observing all browser activities, which is particularly useful for debugging or demonstrating automation scripts.
