Build a Real Microservices App (NestJS, Kafka, PostgreSQL)

Most Node.js tutorials stop at a simple To-Do app. In this course, we’re going strictly professional. We are building EventFlow a real-world event and ticketing platform using a complete microservices architecture.

🚀 Source Code + Next.js Frontend + DevOps

🎓 What We Build
In this series, you will master the "hard parts" of modern backend development. We move beyond monoliths and build a distributed system where standalone services communicate asynchronously using Apache Kafka.

Key Features You Will Build:
Microservices Architecture: Decouple logic into Auth, Events, Tickets, and Notification services.
Event-Driven Communication: Use Kafka topics to handle complex workflows asynchronously.
Production-Grade Data Layer: PostgreSQL with Drizzle ORM for type-safe database interactions.
Robust API Gateway: A central entry point with Global Exception Filters and Response Interceptors.
Shared Microservices Library: Create a custom internal NPM package to share DTOs, interfaces, and utilities across services.

🛠 The Tech Stack

Framework: NestJS (TypeScript)
Message Broker: Apache Kafka (Redpanda for local dev)
Database: PostgreSQL + Drizzle ORM
KV Store: Redis (for Rate Limiting)
DevOps: Docker & Docker Compose
Frontend (Pro Only): Next.js 15, TanStack Query, Zustand, Shadcn/UI
