Is it possible to access a global property from my vue instance when setting a default prop value in my component?
This is what I would like to achieve
props: {
id: {
type: String,
default: this.$utils.uuid
}
}
I attempted to use an arrow function without any success
props: {
id: {
type: String,
default: () => this.$utils.uuid
}
}
It seems like achieving this in the exact way you want may not be possible. This is because props are shared objects among component instances. One solution would be to either utilize a global $utils or introduce an internal data item instead of directly relying on the prop id within your component:
Implementing an internalId data item:
export default {
props: {
id: {
type: String,
default: null
},
data () {
return {
internalId: this.id || this.$utils.uuid
}
}
}
Utilizing the global Vue object
(this approach depends on how you installed your utils plugin):
import Vue from 'vue'
export default {
props: {
id: {
type: String,
default: Vue.$utils.uuid // The specifics depend on your plugin setup
}
}
}
