Knowing when to use Provide/Inject and when to use config.globalProperties in Vue.js is essential

Working on a small VueJs SPA with my first experience with VueJs 3. Previously, you could easily add helpers and classes to the Vue instance using prototype. However, VueJs 3 has eliminated this capability and introduced two new options:

provide / inject
config.globalProperties

Personally, I find option 2 more appealing as it is straightforward to implement. Option 1, on the other hand, is a bit confusing to me. Why do you have to explicitly add the inject in the child component instead of it happening automatically?

Are there specific use cases for using options 1 and 2? I'm curious because adding helper classes under config seems odd to me. The naming is just strange.

Answer №1

By utilizing provide/inject, data can be seamlessly transferred from a higher-level parent component to a deeply nested child component without the hassle of prop drilling.

Employing config.globalProperties ensures that the data is accessible across all components, as opposed to solely in the components where it is needed.
