1. "sub topic" - subscribe to a topic
2. "unsub topic" - unsubscribe from a topic
3. "pub topic" - publish to a topic
4. "ls" - list all topics
5. "quit" - disconnect from the broker

How to run

1. clone this repo git clone https://github.com/BenMeehan/goscribe.git
2. cd into the cloned directory
3. run go build
4. run the resultant binary ./goscribe [-h HOST] [-p PORT]

Note : HOST and PORT are optional. Defaults to 0.0.0.0 and 8090

Gotcha's

GoScribe is a very simple broker. Think of it as a chat room server but for pub-sub. It does not provide any message persistance or queueing for now. What is not recieved by the subscribers is lost for ever!

TODO

• client library
• queueing messages inside broker
• message persistence
• health check if subscribers
