How to wait for data in store and use it in beforeMount?

Question

Vue.js

Now I have a method in beforeMount that uses data from the store
. When the component is loaded for the first time, this method in beforeMount fires, but the data has not yet arrived in the store.

I'm trying to watch store changes via vm.$watch(spyData, myMethod)

But that doesn't solve the problem

Answer 1

1. made spyData a computed property
2. in beforeMount() made a check:
spyData.length > 0 ? myMethod() : null
3. And accordingly, beforeMount() already had:
vm.$watch(spyData, myMethod)
