How to access to a child method from the parent in vue.js

Question

I have two nested components, what is the proper way to access to the child methods from the parent ?

this.$children[0].myMethod() seems to do the trick

Answer 1

To communicate a child component with another child component I've made a method in parent which calls a method in a child with:

this.$refs.childMethod()

And from the another child I've called the root method:

this.$root.theRootMethod()

It worked for me.
