In Vue.js, the provide and inject features are inherently non-reactive, but developers can circumvent this limitation by using the data() function or Vue.observable to create reactive objects that maintain their reactivity when passed down through provide and inject. The data() function allows objects initialized within it to become reactive, updating the Vue application whenever changes occur. Alternatively, Vue.observable, introduced in Vue 2.6 and renamed reactive in Vue 3, offers more flexibility for creating reactive objects without relying on the data function. Thorsten Lünborg, a Vue core team member, developed the vue-reactive-provide mixin as another method to achieve reactive provide/inject. Although this technique can simplify certain scenarios, it should not replace props and events, which offer a clearer and less complex approach for data passing in most cases. Developers are advised to avoid using reactive provide/inject for two-way data binding, as it can lead to inconsistency and confusion, and should consider this technique only under specific circumstances, such as avoiding prop drilling or when Vuex is deemed excessive for simple state management.
