Microservices with NestJS: Building a Food Delivery Backend

Modern backend development requires more than just building monoliths; you need to know how to scale systems using microservices. This written course guides you through the process of designing and implementing a highly scalable microservice architecture (MSA) using NestJS. You will transition from basic backend concepts to advanced distributed systems, learning how to handle inter-service communication, data consistency, and system resilience. Through clear explanations and practical code examples, you will build the foundational architecture for a robust food delivery backend. What you will learn: Understand the core principles of microservices and how they differ from monolithic architectures; Configure NestJS microservices using various transport layers like TCP and gRPC; Implement asynchronous communication patterns using message brokers such as RabbitMQ; Manage data consistency across distributed services without complex transactions; Apply modern containerization patterns using Docker to run and orchestrate your services; Handle error propagation and system resilience in a distributed environment. This course starts with foundational microservices concepts and NestJS setup before guiding you through the implementation of dedicated services for users, orders, and delivery tracking. Designed for intermediate backend developers and ambitious beginners with basic Node.js knowledge, this text-based guide requires no prior microservices experience. Start reading today to elevate your backend engineering skills to the architectural level.
