Using primevue and other npm package on Dashboard 2.0 ui-template

Good day,
I try to use the primevue UI suite with the ui-template in Nodered Dashboard 2.0.
I installed PrimeVue with the npm in the .node-red directory.

In the ui-template I insert the following code to text an example find on the PrimeVue site.


<template>
    <div class="card flex justify-center">
        <v-text> "hello world" </v-text>
        <CascadeSelect v-model="selectedCity" :options="countries" optionLabel="cname" optionGroupLabel="name"
            :optionGroupChildren="['states', 'cities']" style="min-width: 14rem" placeholder="Select a City">
            <template #option="slotProps">
                <div class="flex items-center">
                    <img v-if="slotProps.option.states" :alt="slotProps.option.name" src="https://primefaces.org/cdn/primevue/images/flag/flag_placeholder.png" :class="`flag flag-${slotProps.option.code.toLowerCase()} mr-2`" style="width: 18px"  />
                    <i v-if="slotProps.option.cities" class="pi pi-compass mr-2"></i>
                    <i v-if="slotProps.option.cname" class="pi pi-map-marker mr-2"></i>
                    <span>{{ slotProps.option.cname || slotProps.option.name }}</span>
                </div>
            </template>
        </CascadeSelect>
    </div>
</template>

<script setup>
import { ref } from "vue";
import CascadeSelect from 'primevue/cascadeselect';
const selectedCity = ref();
const countries = ref([
    {
        name: 'Australia',
        code: 'AU',
        states: [
            {
                name: 'New South Wales',
                cities: [
                    { cname: 'Sydney', code: 'A-SY' },
                    { cname: 'Newcastle', code: 'A-NE' },
                    { cname: 'Wollongong', code: 'A-WO' }
                ]
            },
            {
                name: 'Queensland',
                cities: [
                    { cname: 'Brisbane', code: 'A-BR' },
                    { cname: 'Townsville', code: 'A-TO' }
                ]
            }
        ]
    },
    {
        name: 'Canada',
        code: 'CA',
        states: [
            {
                name: 'Quebec',
                cities: [
                    { cname: 'Montreal', code: 'C-MO' },
                    { cname: 'Quebec City', code: 'C-QU' }
                ]
            },
            {
                name: 'Ontario',
                cities: [
                    { cname: 'Ottawa', code: 'C-OT' },
                    { cname: 'Toronto', code: 'C-TO' }
                ]
            }
        ]
    },
    {
        name: 'United States',
        code: 'US',
        states: [
            {
                name: 'California',
                cities: [
                    { cname: 'Los Angeles', code: 'US-LA' },
                    { cname: 'San Diego', code: 'US-SD' },
                    { cname: 'San Francisco', code: 'US-SF' }
                ]
            },
            {
                name: 'Florida',
                cities: [
                    { cname: 'Jacksonville', code: 'US-JA' },
                    { cname: 'Miami', code: 'US-MI' },
                    { cname: 'Tampa', code: 'US-TA' },
                    { cname: 'Orlando', code: 'US-OR' }
                ]
            },
            {
                name: 'Texas',
                cities: [
                    { cname: 'Austin', code: 'US-AU' },
                    { cname: 'Dallas', code: 'US-DA' },
                    { cname: 'Houston', code: 'US-HO' }
                ]
            }
        ]
    }
]);
</script>

When I deploy the flow I see only the hello world (the v-text part) but the primevue features isn't rendered.
Can someone help me please.
Thanks in advance.

Hi, we don't support the VueJS's Composition API at the moment, only the Options API, nor do we support the use of import.

You can see how we load external dependencies here: Template ui-template | Node-RED Dashboard 2.0

Then, to write what you have so far in the Options API, it'd be:

export default {
    data () {
        return {
            selectedCity: null,
            countries:[ ... ]
        }
    }
}
