How to Use Slots in Svelte

By | October 3, 2023


Svelte is a popular JavaScript framework known for its simplicity and efficiency in building web applications. One of the standout features of Svelte is its use of slots, which enables developers to create highly customizable and reusable components. In this blog post, we will dive into the details of how to use slots in Svelte effectively to harness the power of AI in web development.

How to Use Slots in Svelte

Slots in Svelte serve as placeholders within a component, allowing you to inject content or elements from outside the component. This dynamic approach makes it easier to build flexible and maintainable UIs. Let’s explore how to use slots in Svelte step by step:

Step 1: Understanding the Basics

To use slots effectively, you need to have a clear understanding of how they work. In Svelte, slots are defined within a component and act as receptacles for content. You can create named slots, which provide more control over where the content is placed, or use the default slot for general content injection.

Step 2: Creating a Slot Component

Now, let’s create a simple slot component in Svelte. First, define your component and include a slot tag where you want external content to be inserted. Here’s an example:

htmlCopy code

<script> let slotContent = "Default Content"; </script> <div class="slot-container"> <slot>{slotContent}</slot> </div>

In this example, we have a slot container with a default content of “Default Content.”

Step 3: Using the Slot

To use the slot component, you can import it into your main application file and provide the desired content within the slot tags. Here’s how you can do it:

htmlCopy code

<script> import SlotComponent from './SlotComponent.svelte'; </script> <SlotComponent> <p>This content replaces the default slot content.</p> </SlotComponent>

In this step, we import the SlotComponent and place the content within the component’s slot. This dynamic approach allows you to customize the content for each instance of the component.

Step 4: Handling Multiple Slots

Svelte also supports multiple named slots within a component, providing even more flexibility. You can define slots with specific names and place content accordingly.

htmlCopy code

<!-- SlotComponent.svelte --> <script> let slotContent = "Default Content"; let headerContent = "Header Content"; </script> <div class="slot-container"> <h2><slot name="header">{headerContent}</slot></h2> <slot>{slotContent}</slot> </div>

You can use multiple slots like this:

htmlCopy code

<SlotComponent> <h1 slot="header">Custom Header</h1> <p>This content replaces the default slot content.</p> </SlotComponent>
