creating a full-stack application using python and javascript involves using python for the backend (often with a framework like flask or django) and javascript for the frontend (typically with a framework like react, angular, or vue.js). in this tutorial, we'll create a simple full-stack application using flask for the backend and react for the frontend.
step 1: setting up the backend with flask
#### 1.1 install flask
first, ensure you have python and pip installed on your machine. then, create a directory for your project and set up a virtual environment:
now, install flask:
#### 1.2 create a basic flask app
create a file named `app.py` in your project directory:
#### 1.3 run the flask app
you can now run your flask application:
your flask server should now be running on `http://127.0.0.1:5000`.
step 2: setting up the frontend with react
#### 2.1 install node.js
make sure you have node.js installed. you can verify this by running:
#### 2.2 create a react application
in a new terminal window (while your flask app is running), create a new react application using create react app:
#### 2.3 install axios
we will use axios to make http requests from our react app:
#### 2.4 create a simple react component
replace the content of `src/app.js` with the following code:
#### 2.5 run the react app
start your react application:
your react app should now be running on `http://localhost:3000`.
step 3: connecting the frontend and backend
you should be able to see your react app displaying items fetched from the flask backend. you can add new items using the input box, and they will be sent to the backend and displayed in the list.
conclusion
you now have a simple full-stack application using python with flask for the backend and javascript with react for the frontend. this tutorial serves as a basic introduction, and you can expand upon it by adding features like user authentication, database integration (using sqlite o ...
