i have read the Vue-beginners guide… and are happy to play-around and learn from the documentation 😉
(if i find the correct part 😉 )
the link to the example boot/components.js is great!
→ that was the missing point 😉
and the components-registration thing was the doc i searched for!
seems i have to search also more in the Vue documentation!!
especially Local-Registration-in-a-Module-System did it for me 😉
