[Vuejs]-How do I check the health of vue router system?, may be something is missing

Welcome to the Vue world. Be ready, you have a lot to learn.

I have see that you have selected parcel as builder.
I prefer webpack as recommended from Vue.

After see that Vue was not loading and i have read how to add Vue to a web with parcel.
I make Vue router works, but nothing more:
https://codesandbox.io/s/38wo1p9yn6
The page remove all JS when loads, maybe it a problem in parcel+condesandbox this example is also not working.

I recommend you move your project Vue-cli or the code sandbox based on Vue-cli.

Also, read the Vue and Vue-router docs to understand how to use it, seems that you need more time on this to build a web.

Hope it helps 🙂
