I have a simple LiveView app that write user input to a temporary markup file (content.typ), drops to System.cmd/2 to process this markup with a CLI (typst), and deliver the output (content.png) to the client In dev, I specify the path for the temporary files as Application.app_dir(:typeset, "pr…

Thank you @LostKobrakai . For future readers: you’d use System.tmp_dir/0 for the path. So if you want to write a content.png, it would go to File.write!( System.tmp_dir() <> "/content.png", your_content_here ) You can tell Phoenix to serve these as static files by adding a plug in MyAppWeb.En…

Thanks — I did check out ex_typst. I shell out (necessitating the temporary file) because I’m using the CLI to generate transparent PNGs, and also (in the future) use typst query from the CLI to extract parameters from the run. (It was a while since I did the earlier expts; with the PDF, the only …
