One-button deploy NCHAN to Heroku. Clicking the deploy button will create a Heroku app with the nchan-buildpack preconfigured for you!
This will run NCHAN with a publisher route at /pub and a subscriber route at /sub. See example pub/sub usage:
# start a subscriber connection
curl <your-url>/sub?id=foobar # id query parameter is the channel
# somewhere else:
curl <your-url>/pub?id=foobar -X POST --data 'hello'
# then, see the message delivered to your open connection!
