Learn how to build a production-ready microservices chat application from scratch and deploy it using Docker Compose & Dokploy for self-hosting! In this complete tutorial, we'll build a Slack/Discord-style chat app using a modern microservices architecture with 4 services: ✅ API Gateway - Single entry point for all client requests ✅ Auth Service - User registration, login & JWT tokens (MySQL) ✅ User Service - User profiles & data management (PostgreSQL) ✅ Chat Service - Conversations & messages (MongoDB + Redis caching) All services communicate through RabbitMQ for event-driven messaging, ensuring they stay decoupled and scalable.
