Dead Simple channel/event publisher - Sinatra Streaming Example

Publisher

What's this?

A example of Sinatra::Streaming
It serves SSEs in a channel/event schema

What can you do with it?

For starters, fire it up with thin start or foreman start.
Then open your SSE/websocket supporting browser (let's go with the latest version of chrome) and hit localhost:3000/test
You'll be in a page with an open EventSource listening to server sent events trough the channel testchannel and for the event testevent

So you can open your irb and:

require 'net/http'
uri = URI('http://localhost:3000/publish')
Net::HTTP.post_form(uri, 'channel' => 'testchannel', 'event' => 'testevent', 'data' => '<br> Hello there')

And look at that, your data is showing up at real-time on your browser

What's next?

Well, I'd love to put in some of my projects models something like notify_to_publisher and have my model send to Publisher its json representation on each create, update, or destroy. Hey! Those sound like events, right?
Let's say I have a Post model and by dropping notify_to_publisher on it, on each CRUD operation the model will send its own json to the server using the post channel on the create, update or delete events.
Yeah, I think that's what I'll do next.
