Light Authentication With Monban

Jul 08, 2014 on Rails Ruby Gem Authentication

If you want to have user authentication on Rails, but don't require something as hard hitting as Devise or Clearance, Monban is the way to go. Monban, like Clearance, is also developed by the folks over at thoughtbot. This gem provides some nifty, intuitive DSL.

authenticate_session(session_params)
sign_in(user)
signed_in?
sign_out
sign_up
current_user

These methods all do what you would think that they do, except maybe authenticate_session, which fetches the necessary keys from strong params during assignment to the user, user = authenticate_session(session_params). You can then call sign_in on the result of this, to sign in the user. Monban also provides some neat callback methods, such as require_login, which is useful if you want to force user authentication before a particular action.

Unlike Devise, it doesn't provide you with specific Monban views or create large migration file for you. However, it still uses Warden and BCrypt for security, so while it is lightweight, it is by no means underpowered.
