I have been using Sinatra for sometime now and I would like to add some realtime features to my web-app by pushing the data via websockets.

I've been using sinatra-websocket. It let's you run the websocket server in the same process and on the same port as Sinatra.

Disclaimer: I'm the maintainer.

require 'sinatra'
require 'sinatra-websocket'

set :server, 'thin'
set :sockets, []

get '/' do
  if !request.websocket?
    erb :index
  else
    request.websocket do |ws|
      ws.onopen do
        ws.send("Hello World!")
        settings.sockets << ws
      end
      ws.onmessage do |msg|
        EM.next_tick { settings.sockets.each{|s| s.send(msg) } }
      end
      ws.onclose do
        warn("websocket closed")
        settings.sockets.delete(ws)
      end
    end
  end
end
