Using Slots Efficiently

A slot is an HTML element. Modern JavaScript offers them in web components, and they essentially work the same in Vue. They tell the browser (or, in this case, Vue) where to put any child elements the component may have. Because slots offer us so much in terms of versatility, let’s learn what they do and how they work.

What are slots?

Slots give Vue components a lot more flexibility. For example, instead of having to nest perhaps unrelated components, we can apply a slot to use our components as containers instead of standalone elements. In addition, the slots can help us generalizse abstract logic and structure into coherent units. Renderless components offer a default slot we can provide with data to make them usable in templates.

Let’s begin learning about slots by looking at a rather complex Vue component that may have child elements.
