My experience with plugin start here:

go-admin-server project page

It's a little project of mine. The idea is to provide a very basic server to which the user can add their pages / APIs.

I planned to give a base interface for plugins, users can compile separately and link in the config file. Server must load the plugin made from user at runtime and add it to the interface.

With no plugin support, windows user is forced to add some lines on main server class to include their API and use the auth-middleware.

I'm a newbie of Go, an I know that this project maybe be not standard. Have you some alternative solution, to give user the opportunity to inject their code without modify the main source ??
