Headless WordPress with SvelteKit Overview
Headless CMS is a modern approach to web development. The frontend and backend are kept apart by it. This increases the freedom available to developers. WordPress, traditionally a monolithic CMS, can be used headlessly. This means it serves as a backend only. In contrast, SvelteKit is a contemporary front-end framework. It’s known for its speed and simplicity. This article will explore integrating headless WordPress with SvelteKit. To demonstrate how to create a dynamic web application is the aim. You will know how to use both technologies at the end.
Introduction to SvelteKit
A framework for creating web applications is called SvelteKit. It is based on Svelte, a component-based JavaScript framework. SvelteKit provides a comprehensive solution for modern web development. It provides functions like as static site generation (SSG) and server-side rendering (SSR). These features improve performance and SEO.
Overview of SvelteKit Framework
SvelteKit simplifies building complex web applications. It takes care of rendering, data fetching, and routing. As a result, there is less boilerplate code. It also expedites and improves the efficiency of development. The framework uses a component-based approach. This means developers can build reusable UI elements.

Integrating Headless WordPress with SvelteKit
Step-by-Step Guide to Setting Up Headless WordPress
Setting up headless WordPress is straightforward. First, install WordPress on your server. Next, install the REST API plugin if it’s not already included. This plugin exposes WordPress content as JSON. Then, create and publish your content in WordPress. This content will be accessible via API endpoints. Ensure you have API keys for secure access. Finally, test the API to ensure it returns your content.
Setting Up a SvelteKit Project
Start by installing Node.js and npm on your machine. To run SvelteKit, you need these tools. Then, use the SvelteKit command-line tool to create a new project. Run the command ‘npm init svelte@next’ in your terminal. To set up your project, adhere to the instructions. Proceed to your project directory after that. Install the required dependencies by using the `npm install` command. Lastly, use ‘npm run dev’ to launch the development server. Your SvelteKit project is now ready for development.
Connecting SvelteKit to WordPress API
First, obtain your WordPress API endpoint. It usually looks like https://yourdomain.com/wp-json/wp/v2/posts. Next, create a SvelteKit component to fetch data from this endpoint. Use the ‘fetch’ API in SvelteKit to get the data. For example, in your SvelteKit component, add:
<script>
let posts = [];
onMount(async () => {
const res = await fetch(‘https://yourdomain.com/wp-json/wp/v2/posts’);
posts = await res.json();
});
</script>
This code fetches posts from WordPress and stores them in an array. Display the posts using SvelteKit’s templating syntax. For instance:
{#each posts as post}
<article>
<h2>{post.title.rendered}</h2>
<div>{@html post.content.rendered}</div>
</article>
{/each}
This template loops through the posts and renders their title and content.

Fetching Data from WordPress Using SvelteKit
Fetching data in SvelteKit is simple. Use the ‘fetch’ API to retrieve WordPress content. Store the data in a reactive variable. This ensures the UI updates automatically when data changes.
Displaying WordPress Content in SvelteKit Components
Display WordPress content using SvelteKit’s declarative syntax. Use components to encapsulate different parts of the UI. This makes the code modular and reusable. For example, create a ‘Post.svelte’ component to display a single post. Use this component in your main page to display all posts.
Handling Routing and Dynamic Content in SvelteKit
SvelteKit handles routing out of the box. Create files in the ‘src/routes’ directory for each route. Use square brackets for dynamic routes. For post detail pages, use ‘[slug].svelte‘ for instance. Fetch the corresponding WordPress content based on the route parameter. This allows content to be rendered dynamically depending on the URL.
You can easily combine headless WordPress with SvelteKit by following these instructions. This configuration makes use of both systems’ advantages. You get a powerful, flexible backend with WordPress and a fast, modern frontend with SvelteKit.
Building a Headless SvelteKit Application
Fetching Data from WordPress Using SvelteKit
Fetching data in SvelteKit is efficient and straightforward. Use the ‘fetch’ API to get content from WordPress. This method retrieves data asynchronously. First, create a SvelteKit component to manage data fetching. Make the fetch request using the ‘onMount‘ lifecycle function. For example:
<script>
import { onMount } from ‘svelte’;
let posts = [];
onMount(async () => {
const response = await fetch(‘https://yourdomain.com/wp-json/wp/v2/posts’);
posts = await response.json();
});
</script>
This code fetches posts from WordPress and stores them in a variable. The UI automatically updates when data is fetched.
Displaying WordPress Content in SvelteKit Components
Displaying content in SvelteKit is intuitive. Use SvelteKit’s templating syntax to render WordPress data. For improved code management, create reusable components. For instance, a ‘Post.svelte’ component might look like this:
<script>
export let post;
</script>
<article>
<h2>{post.title.rendered}</h2>
<div>{@html post.content.rendered}</div>
</article>
This component takes a ‘post’ object as a prop and displays its title and content. In your main component, loop through the posts and render each one using the ‘Post’ component:
<script>
import Post from ‘./Post.svelte’;
let posts = [];
</script>
{#each posts as post}
<Post {post} />
{/each}
This structure makes your application modular and easy to maintain.
Handling Routing and Dynamic Content in SvelteKit
SvelteKit’s built-in routing system simplifies navigation. Define routes by creating files in the ‘src/routes’ directory. For static routes, use plain filenames like ‘index.svelte’ for the homepage. Use square brackets for dynamic routes, like this: “[slug].svelte.” These routes capture URL parameters and allow for dynamic content rendering. For example, a ‘[slug].svelte’ file might look like this:
<script context=”module”>
export async function load({ params }) {
const response = await fetch(`https://yourdomain.com/wp-json/wp/v2/posts?slug=${params.slug}`);
const post = await response.json();
return { props: { post: post[0] } };
}
</script>
<script>
export let post;
</script>
<article>
<h1>{post.title.rendered}</h1>
<div>{@html post.content.rendered}</div>
</article>
This code fetches a specific post based on the URL slug and renders it.
Advantages of Headless SvelteKit Integration
Performance Benefits of Using SvelteKit with Headless WordPress
Integrating SvelteKit with headless WordPress offers significant performance benefits. SvelteKit’s server-side rendering (SSR) ensures fast initial load times. SSR enhances user experience and SEO by providing the customer with fully rendered HTML.Static site generation (SSG) in SvelteKit further boosts performance.

<script>
export let url;
let data = [];
onMount(async () => {
const response = await fetch(url);
data = await response.json();
});
</script>
This component can be used anywhere in your app by passing different URLs.
Enhancing SEO for Headless WordPress with SvelteKit
SEO is crucial for visibility. SvelteKit’s server-side rendering (SSR) significantly boosts SEO. SSR ensures that search engines see fully rendered HTML. Use meta tags to improve SEO further. Set dynamic meta tags based on content:
<svelte:head>
