I made a CLI chat app because I wanted to understand scaling services that have stateful websockets.

The main topic this project demonstrate was a scalable architecture for a system that uses websockets to communicate with clients.

The setup we are tring to achieve locally is here. (Image generated by diagrams.py in ./media directory)

1. cd media
2. pip install -r requirements.txt
3. Download graphviz and add it to your PATH https://graphviz.org/download/
4. python diagrams.py

1. Build server image.

cd server docker build --platform=linux/amd64 -t golang-chat-server .

2. Run docker compose to spin up 2 servers and rabbitMQ.

docker compose up

3. In 2 new terminals, start 2 respective clients connecting to the seperate servers.

cd client/src go run main.go localhost:8080 go run main.go localhost:8081

4. Happy chatting.
