Every time I start a Vue project, I get confused and waste 15 minutes reading the documentation and remembering how to set up Vue.
So this is a tiny template I made for myself so that I can avoid that next time. I don't use a build process, instead it uses the CDN version of Vue and a single HTML / JS file.
I make no claims that this is the "best" way to do it, what the official (and very good) Vue documentation suggests is probably better. This is just what I do.
You can see a demo of what this site looks like on GitHub pages. If it's working correctly, it should say "banana" and "banana!".
Usually I'll download the latest version of Vue with wget https://unpkg.com/vue@3/dist/vue.global.js
and use a version I host myself
instead of relying on the CDN (in case the CDN stops working one day).
