hermes

A dead simple service for pushing events to a web browser.

Usage - Server

brew install leiningen
lein run

Usage - Client

var h = new Hermes({ server: 'ws://localhost:2959' });
h.subscribe('jazzhands', function(e){
  // Do something with the payload...
  console.log(e.data)
})

Hermes takes an optional namespace parameter at instantiation time:

var ninjudd = new Hermes({ server: 'ws://localhost:2959', namespace: 'ninjudd:' });
ninjudd.subscribe('alert', function(e){
  // Alerts for ninjudd
})

var gonzo = new Hermes({ server: 'ws://localhost:2959', namespace: 'gonzo:' });
gonzo.subscribe('message', function(e){
  // Messages for gonzo
})

To bypass namespacing once added, set the second argument of subscribe to true:

var namespaced = new Hermes({ server: 'ws://localhost:2959', namespace: 'ninjudd:' });
namespace.subscribe('alert', true, function(e){
  // All alerts
})

Sending events

curl -v -H "Content-Type: application/json" -X PUT -d '{"num":1}' 'localhost:2960/inbox-count'

Examples

1. Start up your hermes server: lein run
2. In root of the Hermes repo, fire up a little server to serve our example files:

python -m SimpleHTTPServer

3. Point your browser to http://localhost:8000/examples/
4. Send an event: curl -v -H "Content-Type: application/json" -X PUT -d '{"num":1}' 'localhost:2960/inbox-count
