Static sites have become increasingly popular due to their speed, security, and simplicity. When it comes to building static sites, several tools and frameworks are available, but one that’s gaining rapid traction is SvelteKit.
This guide takes you through the journey of creating a static site with SvelteKit, from setup to deployment with Kinsta’s Static Site Hosting, for free.
What Is SvelteKit?
SvelteKit is a robust web framework designed for crafting user interfaces, including static sites. It’s known for its performance, simplicity, and the ability to create components with a declarative approach.
SvelteKit extends the capabilities of the Svelte framework by adding routing, server-side rendering, and more.
Getting Started With SvelteKit
To follow along with this guide, we assume you have:
- Fundamental understanding of HTML, CSS, and JavaScript.
- Basic knowledge of Svelte.
- Node.js and npm installed on your computer.
To build your new SvelteKit application, follow the steps below.
- Scaffold a new project by executing:
npm create svelte@latest my-appThis command scaffolds a new project in the my-app directory, asking to configure some basic tooling, such as TypeScript. Ensure you choose the Skeleton project option and change my-app to the preferred name for your project.
- Navigate into the project directory and install its dependencies:
cd my-app
npm install- Execute
npm run devto start the local development server onlocalhost:5173.
Understanding SvelteKit File Structure
When you open your project in a code editor, you will see the following structure. Understanding this structure is crucial as it helps you organize your code effectively.
/
|-- /src
|-- /lib
|-- /routes
|-- +page.svelte
|-- app.html
|-- /static
|-- svelte.config.js- /src: This is the heart of your project and contains various subdirectories and files:
- /lib: This directory houses custom libraries, utilities, or modules. It’s a good place to store reusable code that may be used throughout your application.
- /routes: The routes directory is crucial for defining the different pages or views in your application. Each page is represented by a .svelte file, such as +page.svelte. These .svelte files contain the components, logic, and styles specific to that page.
- app.html: This file serves as the entry point of your application. It’s where the main structure of your web page is defined.
- /static: This directory is used for storing static assets, such as images, fonts, or any files that don’t need processing by your application. These assets can be directly referenced in your HTML and Svelte components.
- svelte.config.js: This configuration file allows you to customize various aspects of your SvelteKit project. You can use it to configure server-side rendering, define custom layouts, and more.
Routing in SvelteKit
One of the standout features of SvelteKit is its routing system. It follows a file-system-based approach, where URL paths are defined by files and folders in the src/routes directory, making it intuitive and straightforward to manage.
In SvelteKit, every file corresponding to a route must be named +page.svelte. For example, the index file for your SvelteKit site is located in the routes folder and named +page.svelte.
Add the following code to this file to create the home page:
<!-- src/routes/+page.svelte -->
<div class="home_hero">
<h1>Enjoy Static Site Hosting With Kinsta StSH.</h1>
<p>Fast, Secure, Reliable Hosting Solution.</p>
<a href="https://kinsta.com/static-site-hosting/">
<div class="btn">Read more</div>
</a>
</div>
<style>
.home_hero {
display: flex;
justify-content: center;
align-items: center;
flex-direction: column;
text-align: center;
}
.home_hero h1 {
font-size: 60px;
width: 70%;
}
.home_hero p {
color: #6e7076;
font-size: 20px;
}
.btn {
background-color: #5333ed;
padding: 20px 30px;
margin-top: 40px;
border-radius: 5px;
color: #fff;
}
@media (max-width: 700px) {
.home_hero h1 {
font-size: 40px;
}
.home_hero p {
font-size: 16px;
}
}
</style>To create a nested route in SvelteKit, for example, an about page accessible at localhost:5173/about, you need to create a folder within the routes folder with a name that represents the URL path. Within that folder, create a +page.svelte file to be rendered for the route.
Add the following code to routes/about/+page.svelte:
<div class="about_cont">
<h2>About</h2>
<div class="about_info">
<div class="about_text">
<p>
Kinsta allows you to{' '}
<a> href="https://kinsta.com/static-site-hosting/">
host up to 100 static websites
</a>{' '}
for free. This can be done by pushing your code to your preferred Git provider
(Bitbucket, GitHub, or GitLab) and then deploying it to Kinsta.
</p>
<p>
As an alternative to Static Site Hosting, you can opt for deploying your
static site with Kinsta’s{' '}
<a> href="https://kinsta.com/application-hosting/">
Application Hosting
</a>
, which provides greater hosting flexibility, a wider range of benefits,
and access to more robust features. For example, scalability, customized
deployment using a Dockerfile, and comprehensive analytics encompassing real-time
and historical data.

}
@media (max-width: 700px) {
.about_info {
flex-direction: column;
}
.about_img {
width: 100%;
}
}
</style>Any style added to your Svelte component is scoped and won’t affect other components.
It’s essential to understand that SvelteKit handles navigation between pages using standard <a> elements, making the navigation process intuitive. There’s no need to import additional components like <Link> as required in React. In the upcoming section, let’s create a Navigation component to be added to each page.
For the current project, the route structure looks like this:
|-- /src
|-- /routes
|-- /about
|-- +page.svelte
|-- +page.svelteUsing Components in SvelteKit
To make your code more modular, you can create components and import them into your pages. For example, you can create a Navbar.svelte component in the routes folder:
<!-- src/routes/Navbar.svelte -->
<nav>
<a href="/">
<img src="/kinsta-logo.png" alt="" class="logo-img" />
</a>
<div class="nav-links">
<a href="/">Home</a>
<a href="/about">About</a>
<a href="/posts">Posts</a>
</div>
</nav>Then, import it into the +page.svelte homepage like this:
<!-- src/routes/+page.svelte -->
<script>>
import Navbar from './Navbar.svelte'
</script>
<Navbar />
<div class="home_hero">
<h1>Enjoy Static Site Hosting With Kinsta.</h1>
<p>Fast, Secure, Reliable Hosting Solution.</p>
<a href="https://kinsta.com/static-site-hosting">
<div> class="btn">Read more</div>
</a>
</div>
<style>
/* CSS styles */
</style>For global components like Navbar and Footer, which are used across multiple files, create them in the src/lib folder to avoid long import paths. When you create components or modules within the lib folder, you can conveniently import them into any component using the $lib import alias:
<script>
import Navbar from '$lib/Navbar.svelte'
</script>To use standalone components, for example, suppose you need a component only for the About page, create it within the routes/about route, and then import it into the page.
For this project, you can also create a Footer component in the lib folder and add this code:
<div class="footer">
<p>
Hosted with ❤️ by Kinsta's{' '}
<a> href="https://kinsta.com/static-site-hosting">Static Site Hosting</a>
.
</p>
</div>Then, import it into all pages.
Using Layout in SvelteKit
To avoid importing components into many pages, SvelteKit allows you to define layouts for your pages using +layout.svelte files.
Creating a layout that applies to every page is straightforward. Create a file named src/routes/+layout.svelte and customize it with the desired markup, styles, and behavior. The critical requirement is to include a <slot/> element to accommodate the page content.
For example, you can integrate the Navbar and Footer components within this layout:
<script>
import Navbar from '$lib/Navbar.svelte';
import Footer from '$lib/Footer.svelte';
</script>
<div class="layout">
<Navbar />
<slot />
<Footer />
</div>The <slot> element allows the content for each page to be inserted into the layout.
Layouts can also be nested for specific pages. For example, if you have a /dashboard page with nested pages like /profile and /settings, you can create a special layout:
|-- /dashboard
|-- /profile
|-- +page.svelte
|-- /settings
|-- +page.svelte
|-- +layout.svelteProgrammatic Navigation in SvelteKit
SvelteKit provides a goto function for programmatic navigation. For example, to navigate to the /dashboard page after a login action:
<script>
import { goto } from '$app/navigation';
async function login() {
// Perform login action
goto('/dashboard');
}
</script>Styling in SvelteKit
SvelteKit supports traditional CSS for styling your pages. Styles can be defined within your Svelte components using the <style> tag, or you can choose to link external stylesheets.
You might notice that the Navbar and Footer components lack specific styles. To address this, it’s a good practice to apply global styling. This can be achieved by creating a CSS file within the src folder and importing it into your root layout file.
For better organization, create a styles folder within the src directory. This folder can house all your styles. As part of this project, create a global.css file in the styles folder and add the following code:
@import url('https://fonts.googleapis.com/css2?family=Poppins:wght@300;400;500&display=swap');
* {
margin: 0;
padding: 0;
box-sizing: border-box;
}
body {
background-color: #ddd;
font-family: 'Poppins',
sans-serif;
width: 1200px;
margin: 0 auto;
}
a {
text-decoration: none;
}
img {
width: 100%;
}
nav {
display: flex;
justify-content: space-between;
height: 200px;
align-items: center;
}
nav .logo-img {
width: 100px;
}
nav .nav-links a {
padding: 0 20px;
font-size: 18px;
}
@media (max-width:700px) {
body {
width: 100%;
padding: 0 20px;
}
nav .nav-links a {
padding: 0 18px;
}
}
.footer {
width: 100%;
text-align: center;
margin: 100px 0 20px;
}You can then import the CSS file into your layout file so it’s global and works for all files:
<script>>
import Navbar from '$lib/Navbar.svelte';
import Footer from '$lib/Footer.svelte';
import '../styles/global.css';
</script>Loading Data with SvelteKit
When working with SvelteKit, you often need to load data into your layouts, pages, and components. This data can come from external APIs, databases, or your local server. To manage this, you can utilize a +page.js file for pages and +layout.js for layouts.
In your SvelteKit project, a +page.svelte file can have a sibling +page.js that exports a load function. The return value of this function is made available to the page through the data prop. Let’s consider an example: suppose you want to create a route for fetching a list of posts from the JSON Placeholder API.
To load data from the API, create a +page.js file within the posts folder. This file exports a load function.
export const load = async () => {
const title = "Hello World";
return {
title,
};
};The load function is expected to return an object, which is provided as props to the +page.svelte file. The title value can then be accessed with the data prop:
<script>>
export let data;
const title = data.title;
</script>
<div class="blog_cont">
<h2>{title}</h2>
</div>Now, let’s move on to interacting with the JSON Placeholder posts API. To achieve this, you can use the JavaScript Fetch API, but SvelteKit offers its own fetch method that you can use to retrieve data from your API endpoints before rendering a page:
export const load = async (loadEvent) => {
const { fetch } = loadEvent;
const response = await fetch(
'https://jsonplaceholder.typicode.com/posts?_limit=10'
);
const posts = await response.json();
return {
posts,
};
};In the code above, we extract the fetch method from loadEvent and make the API request. The response is then sent as props to the Posts page, looping through and displaying all posts:
<script>
export let data;
const posts = data.posts;
</script>
<div class="blog_cont">
<h2>Posts</h2>
<div class="blog_grid">
{#each posts as post}
<a href={`/posts/${post.id}`} class="blog_card">
<h3>{post.title}</h3>
<p>
{post.body}
</p>
</a>
{/each}
</div>
</div>
<style>
.blog_cont h2 {
font-size: 40px;
margin-bottom: 20px;
}
.blog_grid {
display: grid;
grid-template-columns: 1fr 1fr 1fr;
gap: 20px;
}
@media (max-width: 700px) {
.blog_grid {
grid-template-columns: 1fr;
}
}
.blog_card {
background-color: #bfbfbf;
padding: 20px;
border-radius: 5px;
color: #000;
transition: all 0.5s ease-in-out;
}
.blog_card:hover {
background-color: #5333ed;
color: #fff;
}
.blog_card h3 {
margin-bottom: 15px;
}
.blog_card p {
margin-bottom: 15px;
}
</style>This is what the current file tree looks like:
|-- /src
|-- /lib
|-- Footer.svelte
|-- Navbar.svelte
|-- /routes
|-- /about
|-- +page.svelte
|-- /posts
|-- +page.js
|-- +page.svelte
|-- +page.svelte
|-- +layout.svelte
|-- /styles
|-- global.cssDynamic Routing With SvelteKit
You now have 10 posts displayed on your posts page; if you want to create an individual page for each post, the best way to do it is to create a dynamic route.
To achieve this, you need to receive the slug value from the route and use it as a parameter to query for the post. In SvelteKit, you can do this by creating a square bracket folder with the parameter name. Here’s how you can set up individual post pages:
- Create a [postid] folder within the posts folder. The [postid] represents the dynamic parameter that can hold values like post IDs or slugs.
- In the [postid] folder, create two files:
- +page.svelte: This file will define the layout and structure of your individual post pages.
- +page.js: This JavaScript file will handle the data fetching and logic specific to individual posts.
In the +page.js file, retrieve the postid parameter from the route and use it to query the specific post:
export const load = async (loadEvent) => {
const { fetch, params } = loadEvent;
const { postid } = params;
const response = await fetch(
`https://jsonplaceholder.typicode.com/posts/${postid}`
);
const post = await response.json();
return {
post,
};
};You can then access the data as a prop in the +page.svelte file:
<script>>
export let data;
const post = data.post;
</script>
<div>
<div class="blog_content">
<h3>{post.title}</h3>
<p>{post.body}</p>
</div>
</div>
<style>>
.blog_content h3 {
font-size: 40px;
margin-bottom: 20px;
text-align: center;
}
</style>You can check out the full source code for this SvelteKit project on GitHub. You can also check out the official SvelteKit documentation for more information.
Deploy SvelteKit Static Sites With Kinsta
Kinsta allows you to host up to 100 static websites for free directly from your preferred Git provider (Bitbucket, GitHub, or GitLab).
Before you embark on pushing your SvelteKit site, it’s important to tailor it to your deployment target. In this particular project, we’re focusing on utilizing Kinsta’s Static Site Hosting, which requires configuring SvelteKit as a Static Site Generator (SSG).
Here’s how to get your site pre-rendered as a collection of static files:
- Install the @sveltejs/adapter-static by running the following command:
npm i -D @sveltejs/adapter-static- Next, adapt your svelte.config.js file by replacing
adapter-autowith afallbacktoindex.html:
import adapter from '@sveltejs/adapter-static';
const config = {
kit: {
adapter: adapter({ fallback: 'index.html' }),
},
};
export default config;Now, push your codes to your preferred Git provider. Next, follow these steps to deploy your static site to Kinsta:
- Log in or create an account to view your MyKinsta dashboard.
- Authorize Kinsta with your Git provider.
- Click Static Sites on the left sidebar, then click Add site.
- Select the repository and the branch you wish to deploy from.
- Assign a unique name to your site.
- Add the build settings in the following format:
- Build command:
npm run build - Node version:
18.16.0 - Publish directory:
build
- Build command:
- Finally, click Create site.
And that’s it! You now have a deployed site within a few seconds. A link is provided to access the deployed version of your site. You can later add your custom domain and SSL certificate if you wish.
As an alternative to Static Site Hosting, you can opt for deploying your static site with Kinsta’s Application Hosting, which provides greater hosting flexibility, a wider range of benefits, and access to more robust features. For example, scalability, customized deployment using a Dockerfile, and comprehensive analytics encompassing real-time and historical data.
