Thanks for working on this and adding the test!
I don't think we need to logic twice, I think this can be done like this:

if (isLikelyComponentType(exportValue)) {
  register(...)
} else if (/* is obj & all keys are component */ ) {
      for (const subKey in exportValue) {
        register(
          exportValue[subKey],
          filename + ' export ' + key + '$' + subKey,
        )
      }
}

Is there a reason we need this?
typeof obj === "object" && obj !== null should be enough no?

[Newbie012]

Maybe, but in your condition, values such as Date, [], Map, etc will return true as well, which is not what we want. Or maybe it's an oversight on my end?

[ArnaudBarre]

Hum true, it will still be possible to loop over keys but it's cleaner to not do it for these so we can keep this

I'll check and keep you posted
