Add support for composables and plugins when called from server

[Rednas83]

I know this library is designed to call functions from the client, but I have a use case that I also would like to call functions from the server. Problem is that I am getting an error when called on server level

Is there a way to also make the composables and plugins work on server level? I know that nuxt is able to do this but for this library it only seems to work when called on client level
