Svelte Icons: Svelte 5 & SvelteKit Guide (2026)
Build lightning-fast Svelte 5 and SvelteKit applications with verified, tree-shakable SVG icon packages. Explore reactive prop binding, Svelte runes support, and SSR-safe rendering.
How do you use SVG icons with Svelte 5 runes and SvelteKit?
In Svelte 5 and SvelteKit, SVG icons from libraries like lucide-svelte and @tabler/icons-svelte are imported as native Svelte components with full support for reactive $state() runes and bindable props. These components compile to lightweight static SVG markup during SvelteKit SSR with zero client hydration overhead. Svelte's compiler optimizes template expressions directly, allowing reactive toggling of stroke colors, dimensions, and active states without virtual DOM diffing.

<script lang="ts">
import { Bookmark, BookmarkCheck } from 'lucide-svelte'
let isSaved = $state(false)
function toggleSave() {
isSaved = !isSaved
}
</script>
<button
onclick={toggleSave}
class="flex items-center gap-2 px-3 py-1.5 rounded-lg border border-zinc-800 bg-zinc-900 hover:bg-zinc-800 text-sm font-medium transition"

Svelte & SvelteKit Icon FAQ
How do I use Lucide icons in Svelte 5 with runes?
Install `lucide-svelte` and import icons directly into your `.svelte` component: `<script>import { Sparkles, ArrowRight } from "lucide-svelte";</script> <Sparkles size={20} class="text-indigo-400" />`. Svelte 5 handles prop reactivity and event dispatchers automatically.
Is lucide-svelte compatible with SvelteKit SSR and hydration?
Yes. Lucide Svelte compiles to native Svelte component output with pure inline SVG tags, rendering seamlessly during SvelteKit server-side rendering without hydration mismatches.
Can I dynamically change strokeWidth and color in Svelte?
Yes. Lucide Svelte components expose `strokeWidth`, `size`, `color`, and `class` props that can be bound to reactive state or runes (`$state()`).
What is the best alternative for Svelte if I need 5,000+ icons?
`@tabler/icons-svelte` provides over 5,500 icons with the same component ergonomics and first-class SvelteKit support.
