Our team is looking for a way to generate ChartJs on server-side. Our need is either

generate a data url to pass to php script
generate a image file to a known position so a php script can lately embed in a pdf using mPdf.

Is there an example about how to save image to disk?

The src/example.ts gives an example of saving a chartJs image to disk using .renderToBuffer(), then fs.writeFile().

You can also generate a data url via the .renderToDataURL() function
