Headless mannequin

When it first became a thing, Headless Chrome wasn’t even available for Windows. You could only go headless on Linux with Chrome 59.

And Linux had superior headless browsing before! Virtual frame buffers.

A lot of people still don’t realize you can run Chrome headless on Windows now. Well, you can, and it’s as easy as doing this from Powershell…

cd 'C:\Program Files (x86)\Google\Chrome\Application'

# Dump DOM to the screen
.\chrome.exe --headless --disable-gpu --enable-logging --dump-dom https://www.google.com/

# Save the page as a PDF
.\chrome.exe --headless --disable-gpu --print-to-pdf=C:\Temp\output.pdf https://www.google.com/

# Screenshot the page
.\chrome.exe --headless --disable-gpu --screenshot=C:\Temp\screenshot.png https://www.google.com/


Now what about automating Headless Chrome with Python and Selenium? Getting started there isn’t much harder.

Optional first step is to set up a virtual environment.

Second step is pip install selenium from your prompt.

Third step is download the chromedriver binary (≥ v2.32) into the directory where you’ll be writing your script.

And then your script can be as simple as…

from selenium import webdriver

chrome_options = webdriver.ChromeOptions()
driver = webdriver.Chrome(chrome_options = chrome_options)
