How Do You Use Web Component Slots?

Web components are a collection of standards that allow us to create reusable components in our web applications. One of the key features of web components is the ability to use slots to insert content into our component.

In this article, we’ll take a look at how to use slots in our web components and how they can help us create more reusable and flexible components.

Slots are placeholders in our component’s template that we can fill with content. We can define multiple slots in our template and give each one a name.

Then, when we use our component, we can specify which slot we want to fill with content. This allows us to reuse the same component with different content in each instance.

For example, let’s say we have a component that renders a list of items. We could define a slot for the list items and another slot for the “add item” button.

Then, when we use our component, we could fill the first slot with a list of items and the second slot with a button that adds items to the list. This would give us a reusable component that we could use to create different lists with different functionality.

Slots can also be used to insert content into specific parts of our component. For example, let’s say we have a component that renders a list of items.

We can also use slots to insert default content into our component if no content is provided.

We could define a slot for the list items and set the default content to an empty array if no items are provided. This would give us a flexible component that could be used to render either an empty list or a populated list depending on the data provided.

In conclusion, slots are an important part of web components that allow us to insert content into our components in a flexible and reusable way.
