A toy chat app

This project takes ideas from NSQ-Centric Architecture (GoCon Autumn 2014) slide.

Overview

The app contains these parts, but you can add as many as you want:

• Chat server: Responsible for receiving & sending messages between clients.

• Archive daemon: Listen for Archive channel & save messages to Mongodb.

• Bot daemon: Listen for Bot channel, do some analysis, then reply.
