Fullstack App Tutorial with FastAPI, React.js, and Chakra UI | FARM stack

Are you looking to build a fullstack web application using modern technologies? Look no further! In this tutorial, we will walk through the process of building a Fullstack App using FastAPI, React.js, and Chakra UI – also known as the FARM stack.

What is the FARM Stack?

The FARM stack is a modern fullstack web development stack that combines FastAPI on the backend, React.js on the frontend, and Chakra UI for the user interface. FastAPI is a web framework for building APIs with Python, React.js is a popular JavaScript library for building user interfaces, and Chakra UI is a simple, modular, and accessible component library for React.

Prerequisites

Before getting started with this tutorial, make sure you have the following prerequisites:

• Basic knowledge of Python and JavaScript
• Python installed on your machine
• Node.js and npm installed on your machine

Step 1: Setup the Backend with FastAPI

First, let’s set up the backend of our application using FastAPI. We’ll start by creating a new Python virtual environment and installing FastAPI and Uvicorn – a lightning-fast ASGI server implementation, using the following commands:

  
    $ mkdir myapp
    $ cd myapp
    $ python3 -m venv env
    $ source env/bin/activate
    $ pip install fastapi uvicorn
  

Next, we’ll create a new file called main.py and write our FastAPI application. Here’s a simple example to get you started:

  
    from fastapi import FastAPI

    app = FastAPI()

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

Finally, we can run our FastAPI application using Uvicorn:

  
    $ uvicorn main:app --reload
  

Step 2: Create the Frontend with React.js and Chakra UI

Now, let’s move on to creating the frontend of our application using React.js and Chakra UI. We’ll start by creating a new React app using Create React App:

  
    $ npx create-react-app myapp-frontend
    $ cd myapp-frontend
  

Next, we’ll install Chakra UI and its dependencies:

  
    $ npm install @chakra-ui/react @emotion/react @emotion/styled framer-motion
  

Now, we can start working on our frontend components using Chakra UI’s reusable and accessible component library.

Step 3: Connect the Backend and Frontend

Finally, we’ll connect our backend FastAPI application with our frontend React app. We can do this by making API calls from our React components to the FastAPI backend using the Fetch API or Axios library.

Here’s a simple example of making an API call from a React component:

  
    import React, { useState, useEffect } from 'react';

    function App() {
      const [data, setData] = useState({});

      useEffect(() => {
        fetch('/api')
          .then(response => response.json())
          .then(data => setData(data));
      }, []);

      return (
        

          
{data.message}
        
      );
    }

    export default App;
  

Conclusion

Congratulations! You’ve now built a Fullstack App using the FARM stack – FastAPI, React.js, and Chakra UI. You can further enhance your application by adding more features, integrating databases, and deploying it to a server.

Happy coding!
