Send messages on different channels using sinatra-websocket - ruby

Question

Is there a way to send messages on different channels using the sinatra-websocket gem?
Basically I'm trying to replace Pusher with sinatra-websocket. Here's what I'm doing with Pusher:
Pusher["my_channel_A"].trigger('some_event_type', my_message)
Pusher["my_channel_B"].trigger('another_event_type', my_message)
What would be the equivalent of that syntax in this sinatra-websocket snippet?
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

Found an answer to this posted here:
get '/socket/live/game/:id' do
if !request.websocket?
puts "Not a websocket request"
else
request.websocket do |ws|
channel = params[:id]
#con = {channel: channel, socket: ws}
ws.onopen do
ws.send("Hello World!")
settings.sockets << #con
end
ws.onmessage do |msg|
return_array = []
settings.sockets.each do |hash|
#puts hash
#puts hash['channel']
if hash[:channel] == channel
#puts hash[:socket]
return_array << hash
puts "Same channel"
puts return_array
else
puts hash[:channel]
puts channel
puts "Not in same channel"
end
end
EM.next_tick { return_array.each{|s| s[:socket].send(msg) } }
end
ws.onclose do
warn("websocket closed")
settings.sockets.each do |hash|
if hash[:socket] == ws
settings.sockets.delete(hash)
puts "deleted"
else
puts "not deleted"
end
end
end
end
end
end
It's still quite verbose. I guess Pusher abstracts away all this through their API.
