Capture screenshot and/or HTML source code data of any given webpage and print it to stdout.
Output format: JSON string containing b64-encoded data.
- Uses Google Chrome in headless mode.
- Works well even with vertically long webpages.
- Webpages with fixed headers generally work well, but fixed footers may lead to unusual results.
