JavaScript Observe to some event from another component in Vue

I have two components:

<div>
    <advertiser-add-component></advertiser-add-component>
    <advertisers-component></advertisers-component>
</div>

These components have the following interface:

First component is a button. I will see a modal dialog when I click on it. The modal contains an Ajax form:

Second component is a table. You already saw it on the first picture So, I would like to rerender the table component after sending the form without page refreshing. Is there some way to "subscribe" to this event (once the modal information is sent) from advertisers-component? How I can organize it with minimum code?

Answer:1

Yes absolutely, for something like this you could spin up a simple event bus, your component would emit an update to the bus, and the other watches for updates to that event type on the bus.

Here's a good example of how to do it:

Im using vue-events package: https://github.com/cklmercer/vue-events

Install the package globally
Add events object in your component with the events to listen, and fire the event from the modal, check this example:

Answer:3

I would encourage you to check this: https://vuejs.org/v2/guide/state-management.html

Basically you have a component (or java class) called a store that holds the data of the table. That data is the one displayed by the table. When submitting the modal, you ask the store to fetch the data again (by sending an event) from your backend where I assume the data is stored.

Since the table displays the data of the store already, the table will update itself automatically.

I have done just that in an application of mine here: https://github.com/Draluy/Jobsearch/blob/master/front/src/components/applications/Application.vue
