Properly Setting Up a FastAPI App in Visual Studio 2022 (Community)
FastAPI is a modern, fast (high-performance), web framework for building APIs with Python 3.6+ based on standard Python type hints. This article will guide you through the process of properly setting up a FastAPI app in Visual Studio 2022 (Community) edition.
Prerequisites
Before you begin, make sure you have the following installed:
- Python 3.6 or higher (Download Python)
- Visual Studio 2022 (Community) (Download Visual Studio 2022)
- Python extension for Visual Studio (Install Python extension)
Creating a FastAPI Project in Visual Studio 2022
After installing the prerequisites, follow these steps to create a FastAPI project:
- Open Visual Studio 2022 and create a new project.
- In the "Create a new project" window, search for "Python Application" and click "Next".
- Enter a name for your project, select a location, and click "Create".
- In the new project, open the
pyproject.tomlfile and add the following dependencies:
[tool.pyproject.dependencies]
fastapi = "*"
uvicorn = {extras = ["standard"], version = "*"}
To install the dependencies, open the terminal (Ctrl + `) and run:
pip install -e .
Creating a FastAPI App
Create a new file named main.py in the project directory and add the following code:
from fastapi import FastAPI
app = FastAPI()
@app.get("/")
def read_root():
return {"Hello": "World"}
Running the FastAPI App
To run the FastAPI app, open the terminal and run:
uvicorn main:app --host 0.0.0.0 --port 8000
Now, you can access the FastAPI app at http://localhost:8000.
