Passing data between Vue components

Currently, I am extracting a language setting from the DOM and assigning it to a global Vue.js variable in the following manner:

const language = document.querySelector('html').getAttribute('lang');
Vue.prototype.$language = language;

This method works effectively, but I recently came across another approach using a Vue.js event bus as shown below:

Object.defineProperties(Vue.prototype, {
    $bus: {
        get() {
            return EventBus;
        }
    }
});

I am curious about the actual difference between these two methods and whether there is a more recommended way to achieve the same outcome?

Answer №1

Using Object.defineProperties is a great option when you need to define property descriptors such as getters, setters, and read-only properties.

However, in your specific case, using Vue.prototype.$language = language; would be a cleaner approach.

If you are interested in Vue's preferred method, you can refer to this guide on adding instance properties to a Vue instance.
