📘 Introduction

FastAPI is a powerful Python framework for building APIs that is both fast and modern. But sometimes you want more than just an API—you also want a user-friendly interface. Instead of running React and FastAPI on two separate servers, you can bundle your React frontend inside FastAPI and serve it directly. This keeps everything neatly packaged together and makes deployment simpler.

In this tutorial, you’ll learn how to set up a project with a frontend folder for React and a backend folder for FastAPI, then mount the React build output in FastAPI so that your entire full-stack application runs from a single server. You’ll also learn how to request FastAPI endpoints in React using Axios.

✅ Prerequisites

Before starting, make sure you have the following:

🐍☑️ Python installed
📦☑️ Pip installed
🌐☑️ A virtual environment (venv) created and activated
🌐☑️ Node.js installed
📦☑️ npm installed

📂1️⃣ Create the Project Structure

We’ll start by creating folders for both frontend and backend:

fullstack_project/
│── backend/
│── frontend/
  • backend/ → contains your FastAPI app
  • frontend/ → contains your React app

⚡2️⃣ Set Up the Backend (FastAPI)

Move into the backend/ folder.

cd backend

Create a requirements.txt file and add the following Python packages:

fastapi
uvicorn

Install the packages using pip:

pip install -r requirements.txt

Now create main.py with the following code:
