How is a SPA application created from scratch in stages, using Vue as an example?

Question

Vue.js

Hello! I apologize immediately for the noob questions, I want to ask experienced people. I myself am a layout designer with little experience with Wordpress, but in the near future I want to study SPA development from start to finish. The technology itself pretty much breaks my idea of ​​frontend / backend, so I came here.
How is the process of developing such an application? For example, a small online store or portal. That is, we make up a site template + admin panel, then we “embed” vue into it and write a server on node / laravel / etc?
I want to know the sequence of the workflow in detail, at least for a superficial understanding.
Sincerely))
