Demo

Try it! Let out your pirate duck.

Using the demo to talk about PubNub

The demo is specifically designed to be used in demo environments. Use the following as a guide.

1. This is the latest message sent on the ducks.talk channel. Name, time and content are all represented.
2. The talk bubble opens an overlay and calls the history api for the last 20 messages in the ducks.talk channel.
3. The duck is always the latest color message sent in the ducks.color channel. Shows how a chat room can turn into a connected experience, easily adding functionality not normally found in standard 'chat' solutions.
4. Send a message to the ducks.talk channel. Sends the message up to the PubNub service and then the application receives that message and shows it in 1. and 10..
5. Clicking the message word opens an overlay to allow users to send custom messages to the ducks.talk channel.
6. Send a color message to the ducks.color channel. Sends the message up to the PubNub service. The application receives that message and shows it in 3. and 11..
7. Clicking the change color words opens an overlay to allow users to send custom color messages to the ducks.color channel.
8. Using PubNub's presence service on the ducks.talk channel, the application knows how many other ducks are connected.
9. Each instance of the application generates a random duck name every time it is loaded. This is used as the UUID when interacting with the PubNub API.
10. The last ducks.talk message is listed here. aria-polite is used to announce the text change when using screen readers.
11. The last ducks.color message is listed here. aria-polite is used to announce the color change when using screen readers.
12. The last dance, the last message sent on the ducks.dance channel is listed here.
13. Clicking the "Show PubNub message log" will show the last 30 messages sent to and recieved from the PubNub service, in realtime. Use this to show developers how the JSON payload is packaged and displayed to the interface.
14. "Woof!" is considered a bad word in the pirate duck language. As such, it is always changed to "Quack!" through a very simple "Before Publish" PubNub Function. Use this to describe how Functions can interact with the content flowing through the network.

In addition to all of that, there is an "After Publish" PubNub function that listens to all messages posted to ducks.talk and ducks.color. The last three messages are stored in the KV Store. If the three are matched against a 'magic set', the function sends a 'dance' message to the ducks.dance channel. The dance aligns to one of the animations from animate.css. The duck will dance in response. Try Yellow, Red, Blue or "Quack!", "Quack!","Quack!". The full set of magic sequences can be found in the function-dance.js file in PubNubFunctions/duck-dance.
