This is the official PubNub Ruby SDK repository.

PubNub takes care of the infrastructure and APIs needed for the realtime communication layer of your application. Work on your app's logic and let PubNub handle sending and receiving data across the world in less than 100ms.

You will need the publish and subscribe keys to authenticate your app. Get your keys from the Admin Portal.

1. Integrate PubNub into your project using RubyGems:

   gem install pubnub

2. Create a new App.rb file and add the following code.

   require 'pubnub'
   
   pubnub = Pubnub.new(
       subscribe_key: :mySubscribeKey,
       publish_key: :myPublishKey,
       uuid: :myUniqueUUID
   )

   This is the minimum configuration you need to send and receive messages with PubNub.

callback = Pubnub::SubscribeCallback.new(
    message: ->(envelope) {
        puts "MESSAGE: #{puts envelope.result[:data][:message]['msg']}"
    },
    presence: ->(envelope) {
        puts "PRESENCE: #{envelope.result[:data]}"
    }
)
pubnub.add_listener(callback: callback)

pubnub.subscribe(
    channels: ['my_channel'],
    with_presence: true
)

pubnub.publish(
    channel: 'my_channel',
    message: { text: 'Hello world' }
) do |envelope|
    puts envelope.status
end
