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.
