The draw Transition
The draw transition animates SVG path strokes by progressively revealing them.
Import
Comes from svelte/transition.
import { draw } from "svelte/transition";Apply to a path
Attach to an SVG <path> element with a stroke.
<svg viewBox="0 0 100 100">
{#if visible}
<path transition:draw={{ duration: 1000 }} d="M10,50 L90,50" stroke="black" />
{/if}
</svg>Stroke Required
The path must have a visible stroke. Fill-only paths cannot be drawn.
Duration and Easing
Like other transitions, accepts duration, delay, and easing.
Use Cases
Logo reveals, signature animations, mathematical drawings, infographic intros.
Combine with Fade
Use in:draw and out:fade for entrance vs exit symmetry.
Calculating Length
The transition uses getTotalLength() internally. Complex paths animate naturally.
Multi-path Animation
Sequence draws on multiple paths using delay for orchestrated reveals.
{#each paths as p, i}
<path d={p} stroke="black" transition:draw={{ delay: i * 100 }} />
{/each}Performance
Smooth on most devices; very long paths may need shorter durations on mobile.
Browser Support
Works everywhere SVG and CSS animations are supported (all modern browsers).
