🎯 Build a Microservices-Based Grocery Ordering Platform | Spring Boot + Firebase + Docker

In this full-stack backend architecture tutorial, we walk you through the design and implementation of a scalable Grocery Ordering Platform using a modern microservices approach.

🔧 Tech Stack Used:

Java + Spring Boot 3
Firebase Authentication (JWT)
Spring Cloud Gateway & Config Server
PostgreSQL with Spring Data JPA
Docker & Docker Compose
Feign Clients for inter-service communication
Testcontainers for Integration Testing

📦 Microservices Covered:

1. *User Service* – Firebase authentication, user roles & profile
2. *Product Catalog Service* – Grocery items with stock & pricing
3. *Cart Service* – Add, update, and manage shopping carts
4. *Order Service* – Place and track orders with real-time data

🛡️ Authentication:
All APIs are secured using Firebase JWT tokens with Spring Security.

🔁 Service Communication:
Uses REST (via Feign Clients) and is ready for Kafka/RabbitMQ integration.

🐳 Dockerized Deployment:
Fully containerized with `docker-compose` for local development and testing.

📘 What You’ll Learn:

Microservice design patterns
Firebase integration with Spring Security
REST API development & API Gateway routing
Centralized config management
Clean code, modular design, and scalable architecture

📂 Includes:
✅ Source Code
✅ Postman Collection
✅ Swagger UI Docs
✅ README with setup instructions
✅ Integration Tests using Testcontainers
