Pipelines

Different with most plug based framework, plug and plug_overridable are bound to endpoint.
It means that this type of plugs called after route. If you need a top-level plug, you should defined it within before block. There's a thorough example:

Ruby

defmodule API do
  use Maru.Router
  
  before do
    plug Plug.Static, at: "/static", from: "/my/static/path/"
  end
  plug Plug.Logger
  plug_overridable :auth, Auth.Guest
  
  pipeline do
    plug A
  end
  post do
    ...
  end
  
  pipeline do
    plug B
    plug_overridable :auth, Auth.Admin
  end
  get :admin do
    ...
  end
end

This router will be executed by such order:

Text

conn 
-> `Plug.Static` 
  -> route(:post, ["/"])    -> `Plog.Logger` -> `Auth.Guest` -> `A` -> 'endpoint block'
  -> route(:get, ["admin"]) -> `Plug.Logger` -> `Auth.Admin` -> `B` -> 'endpoint block'
