Living style guides

Creating reusable components with a clear API is great to avoid duplicating code across the application, but that is not the only reason why you should focus on reusability.

In fact, creating simple and clean components that accept clear props and that are decoupled from the data is the best way to share a library of base components with the rest of the team. Your base generic and reusable components represent your palette of ready-to-use components that you can share with other developers and designers on your team.

For example, in the previous section we created a generic list with title and text, and since it is decoupled from the data it shows, we can use it many times within the app just by passing the right props. If a new list of categories has to be implemented, we just pass a collection of categories to the list component, and it's done.

The problem is that sometimes is not easy for new developers to find out if components already exist or if new ones are needed...
