Microservices with FastAPI 🚀

This project demonstrates how to build a microservices architecture using FastAPI and Redis Streams. It showcases a modern approach to developing asynchronous, scalable, and resilient systems using RESTful APIs and event-driven communication.

This repository complements the Medium article:
Microservices using FastAPI and Redis Streams.

---

Features 🌟

• FastAPI Framework: Fast and modern web framework for building APIs with Python.
• Redis Streams: Implements event-driven communication between microservices.
• Asynchronous Programming: Efficient and high-performance processing using asyncio.
• Scalable Architecture: Modular design with independent microservices for scalability and maintainability.
• Swagger UI: Auto-generated API documentation for seamless testing and development.
• Dockerized Deployment: Containerized services for easy setup and deployment.

---

Prerequisites ⚙️

Before running the application, ensure you have the following installed:

• Python 3.8+
• pip (Python package manager)
• Docker and Docker Compose (for containerized setup)
• Redis (local or hosted instance)

---

Getting Started 🚀

1. Clone the Repository

git clone https://github.com/vramakrishnaparjanya/microservices-with-fastapi.git
cd microservices-with-fastapi

Setting Up the Microservices

• Manual Setup Navigate to Each Service Directory:

Copy code
cd service_name

• Install Dependencies:

bash
Copy code
pip install -r requirements.txt

• Run the Microservice:

Copy code
uvicorn main:app --host 0.0.0.0 --port <PORT>

Access the API: Visit the Swagger UI at:

Copy code
http://localhost:<PORT>/docs

Redis Streams Integration

Redis Streams is used for inter-service communication. Follow these steps to set up Redis:

• Install Redis:

Install Redis locally or use a cloud-hosted service like Redis Cloud. Start Redis Server:

Copy code
redis-server

Configure Redis in the Services: Update the Redis connection details in the settings.py or equivalent configuration files.

Run the Event-Driven Microservices: Services will publish and consume events using Redis Streams.
