⁠What is PhantomJS

PhantomJS⁠ is a headless WebKit scriptable with JavaScript. Often used via WebDriver⁠ for web system testing.

⁠Use Cases

• Headless web testing. Lightning-fast testing without the browser is now possible!
• Page automation. Access and manipulate⁠ web pages with the standard DOM API, or with usual libraries like jQuery.
• Screen capture. Programmatically capture web contents⁠, including CSS, SVG and Canvas. Build server-side web graphics apps, from a screenshot service to a vector chart rasterizer.
• Network monitoring. Automate performance analysis, track page loading⁠ and export as standard HAR format.

⁠Features of this image

This Dockerized⁠ version of PhantomJS is:

• Small: Using Debian image⁠, and removing packages used during build.
• Simple: Exposes default port, easy to extend.
• Secure: Runs as non-root UID/GID 19534 (selected randomly to avoid mapping to an existing user) and uses dumb-init⁠ to reap zombie processes.

⁠Usage

⁠JavaScript interactive shell

Start PhantomJS in REPL⁠:

$ docker run -it --rm fabiocicerchia/phantomjs
>

⁠Remote WebDriver

Start as 'Remote WebDriver mode' (embedded GhostDriver⁠):

$ docker run -d -p 8910:8910 fabiocicerchia/phantomjs phantomjs --webdriver=8910

To connect to it (some examples per language):

• Java:

  WebDriver driver = new RemoteWebDriver(
      new URL("http://127.0.0.1:8910"),
      DesiredCapabilities.phantomjs());
  

  Copy

• Python (after running $ pip install selenium⁠):

  from selenium import webdriver
  from selenium.webdriver.common.desired_capabilities import DesiredCapabilities
  
  driver = webdriver.Remote(
      command_executor='http://127.0.0.1:8910',
      desired_capabilities=DesiredCapabilities.PHANTOMJS)
  
  driver.get('http://example.com')
  driver.find_element_by_css_selector('a[title="hello"]').click()
  
  driver.quit()
  

  Copy
