Share configuration via inheritance¶ ↑

If you have multiple configurations that needs to share some amount of authentication behaviour, you can do so through inheritance. For example:

require "rodauth"

class RodauthBase < Rodauth::Auth
  configure do
    # common authentication configuration
  end
end

class RodauthMain < RodauthBase # inherit common configuration
  configure do
    # main-specific authentication configuration
  end
end

class RodauthAdmin < RodauthBase # inherit common configuration
  configure do
    # admin-specific authentication configuration
  end
end

class RodauthApp < Roda
  plugin :rodauth, auth_class: RodauthMain
  plugin :rodauth, auth_class: RodauthAdmin, name: :admin
  # ...
end

However, when doing this, you need to be careful that you do not use a configuration method in a superclass, and then load a feature in a subclass that overrides the configuration you set in the superclass.
