How to dynamically format date on item-text inside v-autocomplete (Vuetify)

Question

I have this v-autocomplete which receives an array of items to display from GrowthTasks.edges

<v-autocomplete label="Start Week" 
:items="GrowthTasks.edges" item-text="node.growthStartDate" item-value="node.growthStartDate" dense></v-autocomplete>

The item-text receives the text from there by acessing node.growthStartDate, which is a date format like : "2020-05-06".

Now I want to turn it into a format like "2020-W19" , which I know is possible using moment("YYYY-[W]WW") but I dont know how to tell this to item-text.

Basically, I want the result on the item-text to be the same as if I was using :

{{ node.growthStartDate | moment("YYYY-[W]WW") }}

which works.

Any idea on how can do it ?

You can create computed property and return formated dates:

new Vue({
  el: '#app',
  vuetify: new Vuetify(),
  data() {
    return {
      GrowthTasks: {edges: [{growthStartDate: "2020-05-06"}, {growthStartDate: "2020-06-07"}]}
    }
  },
  computed: {
    items() {
      return this.GrowthTasks.edges.map(obj => ({ ...obj, growthStartDate: moment(obj.growthStartDate).format("YYYY-[W]WW") }));
    }
  }
})
