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.
1. Svelte 5 Runes & Icon Integration
In Svelte 5, you can use reactive state runes to smoothly animate and toggle icon states:
<!-- src/lib/BookmarkButton.svelte -->
<script lang="ts">
import { Bookmark, BookmarkCheck } from 'lucide-svelte'
let isSaved = $state(false)
function toggleSave() {
isSaved = !isSaved
}
</script>
<button
onclick={toggleSave}
class="flex items-center gap-2 px-3 py-1.5 rounded-lg border border-zinc-800 bg-zinc-900 hover:bg-zinc-800 text-sm font-medium transition"
>
{#if isSaved}
<BookmarkCheck size={18} class="text-emerald-400" />
<span>Saved</span>
{:else}
<Bookmark size={18} class="text-zinc-400" />
<span>Save Icon</span>
{/if}
</button>Verified Svelte Icon Packages (6)
Svelte & SvelteKit Icon FAQ
How do I use Lucide icons in Svelte 5 with runes?
Install `lucide-svelte` and import icons directly into your `.svelte` component: `<script>import { Sparkles, ArrowRight } from "lucide-svelte";</script> <Sparkles size={20} class="text-indigo-400" />`. Svelte 5 handles prop reactivity and event dispatchers automatically.
Is lucide-svelte compatible with SvelteKit SSR and hydration?
Yes. Lucide Svelte compiles to native Svelte component output with pure inline SVG tags, rendering seamlessly during SvelteKit server-side rendering without hydration mismatches.
Can I dynamically change strokeWidth and color in Svelte?
Yes. Lucide Svelte components expose `strokeWidth`, `size`, `color`, and `class` props that can be bound to reactive state or runes (`$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.
