So, I have found that so-called flatpak has this software for fedora.

What are flatpaks and why are they better or worse than rpm.
Flatpacks are containerized applications. They're nice because you can get access to applications that aren't part of the distro repositories. It allows specific versions of the application's dependencies to be packaged with it. The biggest downside is bloat / redundancy with system libraries.
Separately, there is someone who tried to create a spec file:
https://github.com/meetfranz/franz/issues/647#issuecomment-438224187
But the spec file uses yarn. I had no idea as to what that was so I looked into the repos and came up with yarnpkg which would install 138M worth of stuff. Are there alternatives?
I will try the rpm route unless the flatpak offers a better approach.
Yes, I took a quick look at franz but I'm unfamiliar with packaging node based projects. Also from my limited knowledge of NODE.js it also notoriusly prefers to bundle other NODE dependencies.
Thanks,
Richard
