Guidance for migration from the old PhantomJS based export server?

[khadden-compline]

I have an old ASP.net WebForms site that is still using the PhantomJS based highcharts export server. The code sends the highcharts definition JavaScript via HTTP POST to the old export server listening on port 3003.

I really need to get that code migrated to use the new node-export-server so I can run it the export server in a container on linux. Is there any difference in usage from the client code standpoint? If so, is there a written guide that describes the changes in the interface?

After some guidance from AI, I got this running in a container. And I have been able to export two of my many charts. It looks like all I need to do is change the way I pass the "infile" property. Which, in my old code was passing the chart definition as a stringified json structure. Whereas the new export server seems to expect the chart definition as a json object.

I did see in the health check the text: "A commercial license may be required depending on use."
I do have a license, but I'm not sure how to apply it to the export server. Any ideas?
