Slots are a powerful tool in Vue that allow you to insert arbitrary content into your component templates. This can be useful for many things, from creating reusable template fragments to inserting dynamic content based on logic in your components.

In this article, we’ll take a look at what slots are and how they work, and then examine some common use cases for them.

Slots are declared in a component’s template with the v-slot directive. The value of the v-slot directive is a name that will be used to identify the slot content when inserting it into the template. For example, consider the following component:

This component has one slot, which is unnamed (the default). We can insert content into this slot by using the slot name as an attribute on a child element of our component:

This is some slot content

In this case, the

element will be inserted into the unnamed slot in our component template. If we wanted to give our slot a name, we could do so using the v-slot directive:

//stop here

Now we can insert specific content into each of our slots by using their names as attributes:

//stop here

This is some main content

This is some sidebar content
