Updating data in a VueJS Single File Component

I'm finding myself in a bit of a maze when it comes to understanding how data functions within single file components for VueJS. For instance, in a file named test.vue, my understanding is that you would script something like this:

export default {
  name: 'Testapp',
  data () {
    return {
      msg: 'sample message'
    }
  }
}

Then in another file, let's call it vuescript.js, I might have the following code and reference it from an HTML file:

import Vue from 'vue' import VApp from './test.vue'

var vueApp = new Vue({
  el: '#app',
  render: h => h(VApp)
})

The question arises: How can I access the data object of that template? Ideally, I'd like to create code elsewhere that retrieves data from a server and can be shared across multiple components. This way, there would be a part of data that remains consistent and updates from a central source, while also allowing for component-specific data such as settings and metadata.

In short, I've hit a roadblock after doing some research on how data is accessed and handled within Vue single file components.

Answer №1

In order to access data inside components from outside sources, there are two recommended methods. One way is through event propagation, where the data is passed up to a parent component that can then determine if it should be sent to another component as a prop. The other method involves storing the data in Vuex and accessing it using getters and mutations.

Answer №2

If you're looking to share a data property among various components, consider leveraging mixins.

Mixins serve as a versatile method for dispensing reusable functionalities to Vue components. Within a mixin object, you can include any component options. By incorporating a mixin into a component, all of the mixin's options will be seamlessly integrated into the component's own set of options.
