How to Use SVG in SolidStart
SolidStart's fine-grained reactivity pairs naturally with SVG — here's how to wire icons into Signals cleanly.

Importing and Rendering SVG Components
SolidStart's Vite foundation supports SVG-to-component plugins (`vite-plugin-solid-svg` and similar), converting files into `<Icon />` components with full prop passthrough. For one-off icons, inline SVG directly in JSX works without any plugin dependency and keeps the component tree simple.
- vite-plugin-solid-svg converts files into typed Solid components
- Inline SVG in JSX needs zero additional configuration
- Both approaches support standard SVG props (class, style, fill)
Signal-Driven Dynamic Icons
Solid's Signals make dynamic icon behavior clean: bind `fill` or `stroke` attributes directly to a Signal value for reactive color changes without any wrapper state management, and Solid's fine-grained updates mean only the specific attribute re-renders — not the whole icon component — for genuinely efficient interactive SVG.
- Bind SVG attributes directly to Signals for reactive updates
- Fine-grained reactivity updates only the changed attribute
- No wrapper state or extra re-renders needed for dynamic icons
Frequently Asked Questions
Do SVG components work correctly during SolidStart SSR?
Yes — SVG markup renders identically on server and client since it's standard HTML/SVG output; Solid's SSR handles it the same as any other server-rendered component without special configuration.
What's the advantage of binding SVG props to Signals over plain state?
Solid's Signals update the DOM directly without a virtual-DOM diff or component re-render, so a color-changing icon driven by a Signal is more efficient than the equivalent pattern in a virtual-DOM framework.
