I'd started trying to package it and making a service out of it too a while ago, but I never got around to actually finish it or even test it. It might look something like this though.
I also packaged it for a Nixarr, doing much of the same, I do like yours a little better though. Nevertheless, I'll post mine here as well. Package:
{
lib,
buildNpmPackage,
fetchFromGitHub,
}:
buildNpmPackage rec {
pname = "cross-seed";
version = "5.9.2";
src = fetchFromGitHub {
owner = "cross-seed";
repo = pname;
rev = "v${version}";
