FastAPI is a modern, fast (high-performance), web framework for building APIs with Python 3.6+ based on standard Python type hints. It's a fantastic choice for building RESTful and real-time APIs quickly and efficiently. In this guide, you 'll walk you through the steps to install FastAPI on your Windows PC.
Before you get started, make sure you have the following prerequisites in place:
Windows PC: You'll need a Windows-based computer to install and run FastAPI.
Python: Ensure you have Python 3.6 or higher installed. If not, you can download Python from the official website (https://www.python.org/downloads/windows/).
Pip: This is Python's package manager, and it usually comes pre-installed with Python. However, it's a good practice to make sure you have the latest version by running the following command:
Follow these steps to install FastAPI on your Windows PC:
1. Create a Virtual Environment (Recommended):
To keep your FastAPI project isolated from your system Python installation, it's a good practice to create a virtual environment. Open a command prompt and navigate to your project directory (or create one) where you want to install FastAPI.
Now, create a virtual environment. Replace env_name with a name of your choice.
Activate the virtual environment:
2. Install FastAPI and Uvicorn:
FastAPI works seamlessly with Uvicorn, a lightweight ASGI server. Install FastAPI and Uvicorn using pip:
3. Create a FastAPI App:
Now, you can create a FastAPI application. Create a Python file (e.g., main.py) in your project directory and write a simple FastAPI app. Here's an example:
4. Run the FastAPI App:
To run your FastAPI application, open a command prompt and navigate to your project directory. If you're using a virtual environment, make sure it's activated.
Use the following command to start the Uvicorn server:
main:app specifies that the app instance is in the main Python module (main.py).
--reload enables auto-reloading, which is helpful for development.
Your FastAPI app will be running, and you'll see the URL where you can access your API. By default, it's usually http://127.0.0.1:8000. Open this URL in your browser, or use a tool like httpie or curl to interact with your API.
Congratulations! You've successfully installed FastAPI on your Windows PC and created a simple FastAPI app.😎😊
FastAPI is a powerful web framework for building APIs with Python. Installing it on your Windows PC is straightforward, and with its high performance, automatic documentation generation, and Python type hint support, you'll be building robust APIs in no time. Now you can start developing your own FastAPI projects on your windows computer. Happy coding!
