🚀 NestJS Microservices with RabbitMQ, Retries & DLQ — Production Setup That Actually Scales.

🚀 NestJS Microservices with RabbitMQ, Retries & DLQ — Production Setup That Actually Scales ❌ Stop building fragile microservices that silently fail. ✅ Start building systems that retry, recover, and scale automatically. If you're using NestJS and not handling failures, retries, and dead-letter queues (DLQ) properly… your system will break in production. Period. In this guide, I’ll show you a battle-tested architecture using NestJS + RabbitMQ with: 🔁 Retries 💀 Dead Letter Queues (DLQ) ⚡ Event-driven communication 🧱 Scalable microservices 🧠 What You’ll Build A real-world system with services like: authentication rbac quotation packages generate-quotation-pdf generate-quotation-ai subscription-plans user-subscriptions notifications send-otp 🏗️ Architecture Overview API Gateway → RabbitMQ → Microservices (Consumers) 👉 No direct service-to-service calls 👉 Fully async & decoupled 📁 Monorepo Structure nestjs-microservices/ │ ├── apps/ │ ├── api-gateway/ │ ├── authentication/
