VueJS is Javascript frontend library which makes my happy in my daily workflow. It's easy to understand and is supported by many modules and libraries - especially NuxtJS. The downside: is a library intuitive you will don't read the (whole) documentation. And this is exactly what happened to me.
I recommend to read this page, but on short:
// do this in your child component (f.e. named mycomponent)
this.$emit('myevent')
// and this in the parent component
<mycomponent @myevent="someOtherFunction" />
Typically I catch emit events with the $on(...) function, but it's not necessary. You can catch your custom-event as well as a click event on your component in the html.
