how can i use Vue JS with Node js express.

Hello,

How can I integrate Vue.js with a Node.js Express server?

I want my Node.js server to provide data to my Vue.js site or for the Vue.js front end to send data to my server. However, I am uncertain about the correct location to place my Express app.js file within the project structure. Could you please guide me on how to properly organize my files so that the Express server and Vue.js front end can communicate effectively? Thank you!
