Install on SvelteKit

Measure visits to your SvelteKit website using the script from your Jelto product.

Before you start

If you don't have a Jelto account yet, create one. Register the published hostname in Jelto and copy the complete script from Settings → Installation. You need permission to edit and publish the site. If your platform restricts custom scripts, confirm that your plan provides this feature.

Add the script

  1. Open src/app.html. Add the copied tag inside <head>, after %sveltekit.head%. Keep %sveltekit.head% and %sveltekit.body% intact. If you use SvelteKit nonce-based CSP, also add nonce="%sveltekit.nonce%" to the tag.
  2. Preserve the copied data-product, data-endpoint and src values.
  3. Build and deploy with your existing SvelteKit adapter.

This example uses Jelto’s standard cookieless script. Replace YOUR_PRODUCT_ID with your public product ID (prd_8f3kq2m9x1) from Settings → Installation. If your copied tag uses a custom tracking domain, cookie mode or additional options, preserve those values:

<script defer
  data-product="YOUR_PRODUCT_ID"
  data-endpoint="https://app.jelto.io/v1/e"
  src="https://app.jelto.io/jelto.js"></script>

Verify

Open the published homepage in a normal browser, navigate to another page, then use Jelto's Check traffic for the actual hostname. Follow Verify website tracking. For a site with client navigation, check a route change and the Back button as well as a full reload.

Common problems

Do not add another tracker to +page.svelte or reinitialize it on each route change. Allow the tracking host in your CSP as shown in Endpoints and content security policy.

If traffic is still missing, check collection troubleshooting. For optional route, exclusion and download settings, use Script configuration.
