[Vuejs]-Best practice of structuring data in a vue app

I’m not fond of any store/global state management.
They are just singletons for me. In ESM a module is kinda a singleton, so put your data in a module and use it in any place you want 🙂

data.js:

import {reactive} from 'vue'
import api from './api.js'

let loadingPromise;
const data = reactive({
   // enter some default values to display or mark it as not loaded
   loaded: false
})

export function loadData(){
    // start loading data when first demanded
    loadingPromise ??= api.get('my-endpoint')
    // this will update your components reactively
    .then(responseData => Object.assign(data, responseData, {loaded: true})) 
    
    return data; // just return the reactive data even if it's not loaded yet

}

Component.vue

<script setup>

import {loadData} from './data.js'

const data = loadData()

</script>
<template>
<div v-if="!data.loaded">Not loaded yet...</div>
<div v-else>
<!-- display your component content here -->
</div>
</template>
