Creating a dependency injection component

Accessing data directly from a child or a parent component without knowing whether they exist can be very dangerous.

In Vue, it's possible to make your component behavior like an interface and have a common and abstract function that won't change in the development process. The process of dependency injection is a common paradigm in the developing world and has been implemented in Vue as well.

There are some pros and cons to using Vue's internal dependency injection, but it is always a good way to make sure that your children components know what to expect from the parent component when you're developing it.

Getting ready

The prerequisite for this recipe is Node.js 12+.

The Node.js global objects that are required for this recipe are as follows:

• @vue/cli
• @vue/cli-service-global

To complete this recipe, we will use our Vue project and the Vue CLI, as we did in the Creating a dynamically injected component recipe.
