Using Vue.js to share events and data across various components

I am currently working on an application that features a Google map with a places autocomplete controller, similar to the example provided by Google at this link.

Whenever an address is searched or selected, or when the map bounds are changed, I trigger an Algolia search. This search has an event called onResult, which is fired upon receiving a response.

My goal is to convert all of this into Vue.js components. So far, I've successfully created separate components for the Google Maps display and the autocomplete feature.

I first load the autocomplete component and then use the mounted section of the Google Maps component to attach it as a controller.

Where I encounter difficulties is in the interaction between these components. For instance, when the place changes (an event from the autocomplete), I need to recenter the map and perform the search. However, since they are two different components, accessing the Google map becomes challenging.

Furthermore, when implementing the Algolia search, I also require a reference to the map in order to pass the marker when the event is triggered.

I initially attempted using a simple Vuex store, but it feels like tightly coupling the components. So, my question is: Have I overlooked something, or should I consider utilizing global event buses and simple stores instead?

Answer №1

Summary:

Vuex could be the solution, but further code examination is required to provide a definite answer

There are various approaches to tackle this issue, however, I will only outline two methods.

Global State Management (Vuex), and props/listeners

Global State Management (Vuex)

If you anticipate having only one instance of each component (such as one map and one autocomplete), this offers an easy, swift, and reliable resolution. Both components do not need to communicate directly with one another; instead, they interact with the global store. The autocomplete feature updates the data in the store, whereas the map remains informed whenever the subscribed variables change, ensuring it updates accordingly.

The drawback, however...
Utilizing Vuex may complicate reusability of components. When dealing with more than one instance (for example, two autocompletes and two maps), complexity may arise, necessitating additional measures.

Props/Emit

If there exists a direct link between the two components, whether they are siblings or possess a parent-child relationship, leveraging this interaction method (in my humble opinion) proves advantageous.

The autocomplete component can be equipped with an @change event or even a v-model, which the parent component can bind to the map component through a prop.

You might already be following this approach, which is not incorrect, yet without reviewing any actual code, assessing the situation accurately becomes challenging.
