@thetutlage Any idea when this will get merged? I am hoping to convert to Adonis very soon! :)

Couple of changes here.

First

Can you rename the method getCreateServerInstance to getInstance, as it makes more sense when you call it as Server.getInstance().

Second

Please rename httpCreateServerInstance to httpInstance and define it to null inside constructor.

Finally it will be great to have some tests, where you can access the instance. It will be simple but makes the future changes more solid.
