Installing FastAPI On A PC

FastAPI is a modern web framework for building APIs with Python 3.6+ that is fast, simple, and easy to use. In this article, we will go through the steps to install FastAPI on your PC.

Step 1: Install Python

Before installing FastAPI, you need to have Python 3.6 or higher installed on your PC. You can download the latest version of Python from the official website (https://www.python.org/downloads/).

Step 2: Create a Virtual Environment

It’s always a good practice to create a virtual environment for your projects to isolate dependencies. You can create a virtual environment using the following command:

python3 -m venv myenv

Step 3: Activate the Virtual Environment

Activate the virtual environment that you just created using the following command:

source myenv/bin/activate

Step 4: Install FastAPI

Now that you have Python installed and the virtual environment set up, you can install FastAPI using pip (Python’s package installer) by running the following command:

pip install fastapi

Step 5: Install uvicorn

Uvicorn is a lightning-fast ASGI server implementation, using uvloop and httptools. You can install uvicorn using pip by running the following command:

pip install uvicorn

Step 6: Create Your First FastAPI App

You can now create your first FastAPI application by creating a Python script with the following code:

from fastapi import FastAPI
    
app = FastAPI()
    
@app.get("/")
def read_root():
    return {"Hello": "World"}
    

Run your FastAPI app using uvicorn by running the following command:

uvicorn your_app_module_name:app --reload

Your FastAPI app should now be running on http://localhost:8000/. You can access it in your web browser or using tools like curl or Postman to test your API endpoints.

That’s it! You have now successfully installed FastAPI on your PC and created your first FastAPI application.
