The single-file SDK

One self-contained script renders any collection into a placeholder, mounts on scroll-in and never touches your app’s state.

4 min read · last updated 2026-05

The single-file SDK is the simplest way to put a widget anywhere. It is one self-contained script that renders a collection into a placeholder element, mounts on first scroll-in and stays isolated from the rest of your page.

<div data-idukki-collection="YOUR_ID"></div>
<script src="https://cdn.idukki.io/widget.js" defer></script>

Why it stays out of the way

  • It renders into a placeholder you control, so you decide where it lives and how much space it gets.
  • It mounts interactivity only when the widget scrolls into view, keeping first load light.
  • It doesn’t reach into your framework’s state, so it won’t cause hydration mismatches.
