Does anyone had installed Devise gem with Sinatra?

Devise is based on Warden and so it should work on Sinatra, I couldn\'t find any related info about how to implement i

    Devise is designed for Rails only. You can't use it with Sinatra.

    You can check out:

    I was able to get it working. There were a few main aspects:

    1. Get Devise working with Rails (Devise is a Rails app, won't work without it)
    2. Setup the mapping (route) on Rack level to support both Rails and Sinatra
    3. Share the sessions between Rails and Sinatra
    4. Setup Warden and make it available to Sinatra

    Here is most relevant part of code from /config.ru:

        #
    
        # ...
    
        # Rest with Rails
        map "/" do
          run MyApp::Application
        end
    
        # Anything urls starting with /slim will go to Sinatra
        map "/slim" do
    
          # make sure :key and :secret be in-sync with initializers/secret_store.rb initializers/secret_token.rb
          use Rack::Session::Cookie, :key => '<< see, initializers/secret_store.rb >>', :secret => '<< copy from initializers/secret_token.rb >>'
    
          # Point Warden to the Sinatra App
          use Warden::Manager do |manager|
            manager.failure_app = AppMain
            manager.default_scope = Devise.default_scope
          end
    
          # Borrowed from https://gist.github.com/217362
          Warden::Manager.before_failure do |env, opts|
            env['REQUEST_METHOD'] = "POST"
          end
    
          run AppMain
        end
    

    See, http://labnote.beedesk.com/sinatra-warden-rails-devise for a complete solution.

    Devise is really just a Rails-centric wrapper with nice helpers for warden, which is the underlying Rack authentication framework. So if you're using Sinatra in conjunction with Rails, you can use Devise in your Rails app, and use warden directly in your Sinatra app, and they will see the same user session data.

    So no, you can't use Devise directly within your Sinatra app, but if you're building a modular app with some pieces in Rails, and other pieces in Sinatra, you can use Devise/Warden among the components.

    There is also https://github.com/jsmestad/sinatra_warden available.
