go-hook is a distributed HTTP pub/sub service. Service discovery is implemented via UDP broadcast, so servers can see each other as long as they are in the same network.

$ make docker

Alternatively you can build it and run it as any other executable:

$ make build
$ ./htm -bind :8000
$ ./htm -bind :8001
$ ./htm -bind :8002

You can subscribe to a topic by opening your browser at http://localhost/topic. Then if someone sends a post request to the sender address you will see it in your browser. Example:

$ curl -X POST -d '{"hello": "world"}' -H 'Content-Type: application/json' http://localhost/topic/sender

Initially the intent was to use this as a webhook server but it's essentially a HTTP pub/sub service.
