FastAPI is a modern, fast (high-performance), web framework for building APIs with Python 3.7+ based on standard Python type hints. In this guide, we will explore how to build Python microservices using FastAPI. We will cover the basics of FastAPI, its features, and provide a step-by-step guide on building a microservice.
pip install fastapi uvicorn Create a new directory for your project and navigate into it: FastAPI is a modern, fast (high-performance), web framework
FastAPI is a modern, fast, and scalable web framework for building APIs with Python. In this guide, we explored how to build Python microservices using FastAPI. We covered the basics of FastAPI, its features, and provided a step-by-step guide on building a microservice. pip install fastapi uvicorn Create a new directory
@app.get("/") def read_root(): return {"Hello": "World"} This code defines a simple FastAPI application that returns a JSON response. To run your microservice, use the following command: FastAPI is a modern
uvicorn main:app --host 0.0.0.0 --port 8000 This command starts the Uvicorn server and runs your FastAPI application. To test your microservice, open a web browser and navigate to http://localhost:8000/ . You should see the following response:
Unfortunately, I couldn't find a free PDF version of "Building Python Microservices with FastAPI" by Sherwin John C. Tragura. However, you can try searching for the book on online libraries or purchasing it from the publisher.
