Packaging guidelines

Entrypoint

Every lovelace module has an entrypoint in the form of a .js file. By default the nixos module will try to load ${pname}.js when a module is configured.

The entrypoint used can be overridden in passthru like this:

{
  passthru.entrypoint = "demo-card-bundle.js";
}
