Python Fast API in 60 Seconds

If you’re looking for a fast and efficient way to build APIs in Python, Fast API is the way to go. In just 60 seconds, you can have a fully functional API up and running.

Getting Started with Fast API

1. Install Fast API using pip:

pip install fastapi

2. Install a web server such as Uvicorn:

pip install uvicorn

3. Create a new file for your Fast API application, for example main.py

Creating Your First API Endpoint

In your main.py file, you can define your API endpoints using Fast API syntax. Here’s a simple example:


from fastapi import FastAPI

app = FastAPI()

@app.get("/")
def read_root():
return {"message": "Hello, World!"}


Running Your Fast API Application

To run your Fast API application, use Uvicorn and specify the location of your main file:

uvicorn main:app --reload

Now you can test your API by visiting http://127.0.0.1:8000/ in your browser or using tools like Postman.

And there you have it! In just 60 seconds, you’ve set up a Fast API application with a basic endpoint. Fast API is a powerful and easy-to-use framework for building APIs in Python, and with its speed and performance, it’s a great choice for any API project.
