@shotleybuilder Sorry for the late reply
I’d be very interested to hear if you could get ChromicPDF to work on a Windows host. It should theoretically be able to communicate with the remote debugging channel through pipes on Windows as well, but maybe the command line switches are different.
a named env variable ‘chromium’
Does you mean the binary is called chromium? Otherwise, here’s the list of executable names ChromicPDF tries to launch Chrome with. If you need it to look for chrome.exe, you could try to checkout the library locally, configure it as local dependency {:chromic_pdf, path: "..."} in your project, and add chrome.exe to this list.
With regards to deployment: Yes, docker is definitely your best option. Then, you also don’t need to get it running on Windows anymore
