Does a singleton with only one public method make sense?

I have a class that exposes only one public method and it’s a singleton.

Would it make sense to just get rid of the class thing and declare properties and methods as global variables and functions? And then exporting only the one "public" function.

Is there anything wrong about using global variables?

>Solution :

In general, avoid the singleton pattern altogether if your class has state, since that becomes global state. But if you can’t (easily):

Yes, this makes total sense with modules. A module is essentially a singleton already (it gets evaluated only once). Notice the variables and functions wouldn’t be global, they’re scoped to the module.
