Collaborate on global functions across the Quasar ecosystem and beyond, including Vue3

Is it plausible to utilize this method for sharing functionality (not data, which is handled by stores) in a Quasar and Vue3 application?

// boot/generic_stuff.js

import {boot} from 'quasar/wrappers'

const function_list = { /* content goes here */ };

export default boot(async ({app}) => {
  app.provide('my_functions', function_list);
  app.provide('my_api_key', 'abc-def');
});

Within my Vue component, I implement the following:

<template>
  This is my api key: {{ my_api_key }}
</template>

<script>
import { inject } from "vue";

export default {
  name: 'MyComponentsName',

  setup() {
    const $my_functions = inject('my_functions');
    const $my_api_key = inject('my_api_key');
    $myFunction.callToSomeFunction();

    return {   
      my_api_key: $my_api_key
    }
  }
}
</script>

Would this approach be suitable if one aims to avoid importing numerous dependencies like Axios or functions needed across multiple scripts such as filters?

Answer №1

If you want to make parts of your application reusable, composables are the perfect solution.

When it comes to Vue applications, a "composable" is a function that utilizes Vue Composition API to package and reuse stateful logic.

The structure goes like this:

  1. In a separate file:
import { ref, onMounted, onUnmounted } from 'vue'

// as per convention, composable function names start with "use"
export function useSample() {
  ...
}
  1. In your component:
<script setup>
import { useSample } from './sample.js'

const { x, y, z } = useSample()
</script>

Refer to the documentation for a comprehensive guide including best practices and naming conventions.
