@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:

pip install fastapi uvicorn Create a new directory for your project and navigate into it:

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:

mkdir my_fastapi_project cd my_fastapi_project Create a new file called main.py :

app = FastAPI()

from fastapi import FastAPI
