This is a simple chat application using Play Framework together with AngularJS. It makes use of a Concurrent.Broadcast object as an Enumerator, a filtering Enumeratee and EventSource as the Iteratee. Together these building blocks facilitate the chat message data flow within the application.
Check out the live demo.
The application uses Server Sent Events to deliver messages to the client and REST calls to send messages to the server. The messages flow from the POST to the Server Sent Events (SSE) stream through Concurrent.broadcast as the central information hub into the chatFeed controller which attaches an Enumeratee / Iteratee chain to the Enumerator provided by Concurrent.broadcast. Filtering for the correct chat room is done with a filtering Enumeratee.
Alternatively, there is another client based on Facebook's React instead of AngularJS. This alternative version can be accessed under
localhost:9000/react. Blog post about the React version will follow.
There are Romeo and Juliet hanging out in Room 1 in order to make looking at the app a little less boring. They are having their balcony scene conversation, but they are confused, uttering the lines at random.
How to run this:
This application will work in Firefox, Safari, Chrome and Opera. It will not work in Internet Explorer, simply because Microsoft for whatever reason does not support Server Sent Events.
