Pet Project: FastAPI + Next.js – Part 1, Backend Setup

In this article, we will discuss setting up the backend part of our pet project using FastAPI. FastAPI is a modern web framework for building APIs with Python, while Next.js is a popular React framework for building web applications.

Setting Up FastAPI

First, we need to create a new Python virtual environment for our project. We can do this using the following command:

python3 -m venv myenv

Next, we need to activate the virtual environment by running the following command:

source myenv/bin/activate

Now, we can install FastAPI and Uvicorn, which is a lightning-fast ASGI server, using the following command:

pip install fastapi uvicorn

Next, we can create a new Python file called main.py and add the following code to create a simple FastAPI application:

        
            from fastapi import FastAPI

            app = FastAPI()

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

Finally, we can run our FastAPI application using the following command:

uvicorn main:app --reload
