Sveltekit + Hygraph


SvelteKit is web app framework for building highly optimized web applications. It is a framework that is built on top of Svelte, a compiler that turns your components into highly efficient JavaScript code.

#Creating a new SvelteKit app

To start, we need to initialize a new SvelteKit project. Open up your terminal, navigate to where you want your project, and run the following command:

npm create svelte@latest my-app

#Add Tailwind CSS to your SvelteKit app

  1. To add Tailwind CSS to your SvelteKit app, run the following command:
npx svelte-add@latest tailwindcss
  1. Update the tailwind.config.js file to reflect the following:

    /** @type {import('tailwindcss').Config} */
    export default {
    content: ['./src/**/*.{html,js,svelte,ts}'],
    theme: {
    extend: {}
    plugins: []
  2. Create a postcss.config.cjs file in the root of your project with the following code:

    module.exports = {
    plugins: {
    tailwindcss: {},
    autoprefixer: {},
  3. Update the src/app.css file (or create it if it doesn't exist), to import Tailwind's styles:

    @tailwind base;
    @tailwind components;
    @tailwind utilities;
  4. Finally, make sure to import the src/app.css file in your src/+layout.svelte file:

    <!-- src/+layout.svelte -->
    import '../app.css';

Now, you should be able to use Tailwind CSS classes in your Svelte components.

#Getting data from Hygraph

Now that you have created your SvelteKit app, it's time to add some data from Hygraph. Start by cloning our demo Hygraph project:

Click here to clone the demo project

After cloning, you will have a simple project that contains one content model called Page that contains fields for Title, Slug, and Body; and one content entry.

If you navigate to the Schema builder and click on the Page model, you will see this:

Demo project - Page modelDemo project - Page model

And if you navigate to the Content editor and view the sample entry details, you'll see this:

Demo project - Sample content entryDemo project - Sample content entry

#Content API

Before you can connect SvelteKit to Hygraph, you will need to configure Content API access permissions for unauthenticated requests.

To do this, go Project settings > Access > API Access > Content API in your Hygraph project, scroll to find the Content Permissions box that reads Would you like us to initialize some defaults?, and click Yes, initialize defaults:

Content API permissionsContent API permissions

Finally, copy the High Performance Content API endpoint from Project settings > Access > API Access > Endpoints. You use it to connect SvelteKit to Hygraph later on.

#Testing a query in the API playground

Next, you should test if you can fetch the information in the sample content entry that we showed you earlier. To do this, navigate to the API Playground in your project and use the following query:

If you execute the query, the response should fetch the sample query in the demo project you cloned.

#Connecting SvelteKit to Hygraph

In SvelteKit, save your VITE_HYGRAPH_URL in an .env file on the project root.

As a result, you will be able to call this key with import.meta.env.VITE_HYGRAPH_URL in any of your files.

This will be where we paste the endpoint URL we copied from Hygraph:


Your root directory will include the following files:

┣ node_modules/
┣ src/
┣ postcss.config.js
┣ svelte.config.js
┣ tailwind.config.js
┗ vite.config.js

#Generating Hygraph content with SvelteKit

After enabling API access, you can start using the Pages query with your SvelteKit app to render content.

#Installing a GraphQL Client

GraphQL clients make communication easier by abstracting away small details and implementing additional features such as static typing of our query results.

We will use the npm package graphql-request because it is lightweight, has excellent TypeScript support, and supports both Node.js and browsers.

Use the terminal to go back to your SvelteKit app, and type the following command:

npm i -D graphql-request graphql

This will install a GraphQL client.

#Getting a list of pages for the homepage

After installing the GraphQL client, go to the src/routes directory and create file called +page.js or +page.ts if you are using TypeScript, and add the following code:

Now that you have a query function that returns the list of pages from Hygraph, you can render them on the homepage. To do this, go to the src/routes directory and create or modify a file called +page.svelte and add the following code:


#Creating dynamic page routes with SvelteKit

Now, that we have a list of pages in our homepage, we need to create a dynamic route for each page.

To do this, create a new directory in the src/routes directory called page/[...slug], a file called +page.js or +page.ts inside this directory. The default SvelteKit install creates a Svelte file called +page.svelte, we will use this file to render the page content.

After this, your source directory should look like this:

┣ lib/
┃ ┗ index.js
┣ routes/
┃ ┣ page/
┃ ┃ ┗ [...slug]/
┃ ┃ ┣ +page.js
┃ ┃ ┗ +page.svelte
┃ ┣ +layout.svelte
┃ ┣ +page.js
┃ ┗ +page.svelte
┣ app.css
┗ app.html

Add the following code to your +page.js or +page.ts file:

Now that you have a query function that returns the page content from Hygraph and created a dynamic route for individual pages, we can render page content using a Svelte file.

To do this, go to the src/routes/page/[...slug] directory and modify the file +page.svelte with the following code:

#Code overview

The code you just added will create a dynamic route for each page. It will fetch the page content from Hygraph and render it on the page.

Congratulations! You have a homepage and a dynamic page route to render all pages and their content.
