Chat App

https://chattington.duckdns.org/

This repo contains the full stack for a real-time chat app with:

• a Spring Boot backend (REST + STOMP over RabbitMQ),
• a Vue frontend,
• PostgreSQL for persistence,
• RabbitMQ for messaging,
• Caddy for local HTTPS reverse proxying.

Structure

• chat-app/ - Spring Boot backend
• chat-vue/ - Vue frontend
• rabbitmq/ - RabbitMQ config (plugins)
• secrets/ - local key material (not for production)
• Caddyfile - local HTTPS reverse proxy

Local HTTPS (recommended)

Windows

1. Add host entry (run PowerShell as Administrator):

echo 127.0.0.1 chat.local >> C:\Windows\System32\drivers\etc\hosts
ipconfig /flushdns

2. Start stack:

docker compose up --build

3. Trust Caddy local CA:

docker compose exec caddy cat /data/caddy/pki/authorities/local/root.crt > caddy-local-root.crt
certutil -addstore -f Root caddy-local-root.crt

Open: https://chat.local

Linux

1. Add host entry:

echo "127.0.0.1 chat.local" | sudo tee -a /etc/hosts

2. Start stack:

docker compose up --build

3. Trust Caddy local CA:

docker compose exec caddy cat /data/caddy/pki/authorities/local/root.crt > caddy-local-root.crt
sudo cp caddy-local-root.crt /usr/local/share/ca-certificates/caddy-local-root.crt
sudo update-ca-certificates

Open: https://chat.local

Environment Variables

Before starting the stack, create a .env file from the example and adjust as needed:

cp .env.example .env

Key variables:

• DB_NAME, DB_PASSWORD
• BROKER_USER, BROKER_PASSWORD
• CLOUDINARY_URL
• DOMAIN_NAME (hostname for both Caddy and backend allowed origin, default chat.local)

Caddy Hostname

The hostname is parameterized via DOMAIN_NAME (set in docker-compose.yml). If you want a different local URL, update:

• DOMAIN_NAME in .env
• the host entry in C:\Windows\System32\drivers\etc\hosts

Environment

Copy .env.example to .env and adjust as needed.

Notes

• RabbitMQ STOMP is enabled via rabbitmq/enabled_plugins.
• The backend expects STOMP on port 61613.
