require 'simplepubsub'

SimplePubSub::Broker.start(port: 8080)

Running the SPS chat clients

1. Open another IRB session and paste in the following:

   require 'sps_chat'

   chat = SPSChat.new port: 8080

2. Open another IRB session and paste the above code into it

3. Type the following in IRB session 1:

   chat.send 'hello'

4. Now type the following in IRB session 2:

   chat.send 'hi!'
