sure! in this tutorial, we will explore the basics of using flask as a backend framework alongside react as a frontend framework. the title "flask over react is a joke" suggests a light-hearted take on the common debate between using flask and react in full-stack development. we won't necessarily choose one over the other; instead, we'll see how they can complement each other.

overview of flask and react

**flask**: a micro web framework for python, flask is lightweight and easy to use, making it a great choice for building web apis.
**react**: a javascript library for building user interfaces, primarily for single-page applications. react allows developers to create reusable ui components.

setting up flask as the backend

1. **install flask**:
first, ensure you have python and pip installed. then, you can install flask using pip:



2. **create a basic flask app**:
create a new folder for your project and add a file called `app.py`. in this file, we will set up a simple flask api.



3. **run the flask app**:
open your terminal, navigate to your project folder, and run:



you should see flask starting on `http://127.0.0.1:5000/`.

setting up react as the frontend

1. **create a react app**:
in a new terminal window, navigate to your project folder and use create react app to set up a new react application:



2. **install axios**:
we will use axios to make http requests to our flask api. install it using:



3. **create a simple react component**:
open `src/app.js` in the react app and modify it as follows:



4. **run the react app**:
in the terminal, navigate to your react app folder (if you aren't already) and start the development server:



accessing the application

1. with the flask server running on `http://127.0.0.1:5000/` and the react app running on `http://localhost:3000/`, open your browser and navigate to `http://localhost:3000/`.

2. you should see the message "hello from flask!" dis ...
