Animating SVG Paths with Motion
Drive SVG path data with spring or tweened stores for smooth vector animations.
Animating SVG Paths with Motion is a free Sveltejs Academy lesson on CoddyKit. This is lesson 4 of 4. You can read the complete lesson below for free — then practise it hands-on in the browser with a built-in code editor and a 24/7 AI tutor. It is part of the Sveltejs Academy learning path, and your progress syncs across the web and the CoddyKit app. The Sveltejs Academy course includes 4 lessons in total.
SVG Paths
SVG <path d="..."> can be animated by tweening the d attribute.
Path String Interpolation
Use a library like flubber to interpolate between two arbitrary paths.
Spring or Tweened
Use a tweened or spring store to drive the interpolated d string over time.
Update Reactively
The d attribute updates each frame, animating the shape smoothly.
<path d={$d} fill="tomato" />Built-in draw
For simple stroke drawing, transition:draw from svelte/transition is enough.
Charts
Animate chart lines, area paths, or pie slice arcs.
Performance
SVG path animation is CPU-bound. Smooth on modern devices but heavy with many paths.
Combine With CSS Transforms
For position/rotation animations, animate the transform attribute on a group.
Coordinate System
Use the viewBox to normalize coordinates; transforms scale consistently.
Use Cases
Animated data visualizations, logo morphs, icon transitions.
Libraries
Combine Svelte with D3 helpers or specific motion libraries for richer SVG work.
Quick Check
How can you animate between arbitrary SVG paths?
Recap
Combine motion stores with path interpolation libraries to animate SVG d attributes between shapes.
