Building a Simple Message Board with Flask Backend and Vue Frontend

First, install Flask using pip install flask , then create app.py importing Flask, jsonify, and request, instantiate the app, and define two routes: /messages for GET returning stored messages and /messages for POST adding a new message to an in‑memory list.

Finally, start the server with if __name__ == '__main__': app.run(debug=True) .

Next, set up the frontend with Vue.js by installing the Vue CLI ( npm install -g @vue/cli ) and creating a project ( vue create board-app ), then run it ( cd board-app && npm run serve ) to serve at http://localhost:8080 .

Create a Board.vue component containing a MessageForm child, a list rendering messages , and methods to add new messages to the local array.

Define MessageForm.vue with a template that includes a text input bound to message and a submit button that emits a new-message event.

Run both the Flask backend ( python app.py ) and the Vue development server ( npm run serve ), then open the browser at http://localhost:8080 to see the working message board.

The article concludes that this simple Flask‑Vue combination can be extended with authentication, additional APIs, and production‑ready deployment.
