Microservices with Node.js & RabbitMQ – Full Project + System Design (Beginner to Advanced)

Description

In this video, we dive deep into Microservices Architecture using Node.js and RabbitMQ with a practical, real-world example. We start by understanding the fundamental differences between Monolithic and Microservices architectures, including their advantages, tradeoffs, and when to use each approach. Then we explore service-to-service communication patterns, covering both synchronous (HTTP) and asynchronous (message queues) communication. To make everything practical, we build a real-world Todo Application where: • A Users Service manages authentication • A Todo Service handles todo creation • An Email Service sends emails when a todo is created • Services communicate using RabbitMQ event-driven architecture Along the way, we also discuss system design concepts, message flow, queue handling, and best practices used in production microservices systems. What You’ll Learn: • Monolith vs Microservices Architecture • Tradeoffs of Microservices (complexity, scalability, deployment) • Synchronous vs Asynchronous Communication • RabbitMQ with Node.js • Event-driven architecture fundamentals • Real-world microservices project structure • Designing Users, Todo, and Email services • Message queues and background processing Timestamps: 00:00 – Introduction 01:05 – What is Monolithic Architecture? 05:22 – What are Microservices? 11:32 – Project Overview: Todo Microservices System Design 15:18 – Implementing RabbitMQ with Node.js 34:42 – Publishing our Package to NPM 41:29 – Publishing Events from Todo Service 52:35 – Consuming Events in Email Service 57:15 – Testing the Complete Flow 59:26 – Outro Source Code: https://github.com/tanujrm44/microservices-yt Who This Video Is For: • Backend Developers • Full Stack Developers • Developers preparing for system design interviews • Anyone learning microservices with Node.js #microservices #nodejs #rabbitmq #systemdesign #eventdriven #backend #distributed #architecture
