Overview ¶

Package rendering provides a function to render HTML to images or HTML after JS execution. It uses the Chrome Debug Protocol through the rod package. It will download a headless Chrome version if needed that matches the current platform.

If the environment variable SND_CHROME_DEBUG=1 it will start the chrome instances in non-headless mode.
