Modifying Data in Another Component in VueJS

I have a classic Vue Component structured like the following:

Vue.component('bar', {
        template: `<div class="bar"></div>`,
        data () {
            return {
                blocks: [
                ]
            }
        }
    });

Furthermore, I also have a Vue Instance outlined as below.

new Vue ({
      el: '#app',
      data: {
        value: 1
      },
      methods: {
        add: function() {
            // code to be added here
        }
      }
    });

When the add function is triggered, there is a requirement to append some data to the component's block values. Given the constraint of not being able to use Vuex, what alternative solutions could be implemented for this scenario?

When it comes to parent-child communication, utilizing props in Vue.js is a straightforward approach:

Firstly, store the data in the parent component under a variable like blocks.
Then, pass this data as a prop to the child component named bar.
Leverage computed properties for any necessary additional processing.
Finally, utilize the template within the child component to display the data.

Below are some steps to guide you through this process:

Begin by defining your component and including the required props:

Vue.component('bar', {
   template: `<div class="bar">{{blocks.length}}</div>`,
   props: ['blocks']
});

Establish the blocks attribute within the parent component (e.g., the main Vue instance):

new Vue ({
   el: '#app',
   data: {
       blocks: []
   },
   methods: {
       add: function() {
           // perform actions with blocks
       }
   }
});

Pass the data down to the child component using props:
```
<bar :blocks="blocks"></bar>
```

If you're looking for a way to handle events in your Vue project, consider using an "Event bus."

Check out this resource for more information: https://alligator.io/vuejs/global-event-bus/

Alternatively, you can create your own state management system by following this guide: https://v2.vuejs.org/v2/guide/state-management.html#Simple-State-Management-from-Scratch

Although these options are available, I highly recommend using Vuex as it becomes challenging to manage events and state as the project scales.
