How to vue 3 vs. svelte for svg icon components: a practical comparison
- Step 1Compare bundle overhead per icon — A Svelte component compiles to minimal JS (~100 bytes overhead per icon). A Vue SFC compiled component is slightly larger (~150 bytes). For 200 icons, the difference is under 10 KB.
- Step 2Evaluate prop reactivity needs — Both frameworks support reactive props for colour and size. Vue's defineProps is more verbose; Svelte's export let is terse. If your icons respond to theme changes, both handle it equally.
- Step 3Consider your team's expertise — If your team already uses Vue (Nuxt, Vite) or Svelte (SvelteKit), use the matching component format for consistency. The performance difference is negligible for icon components.
Frequently asked questions
Which framework produces smaller SVG component bundles?+
Svelte components compile to vanilla JS with no runtime framework overhead. Vue components require the Vue runtime (~50 KB gzipped). For icon-only packages, Svelte has a meaningful advantage.
How does dark mode work with SVG components in each framework?+
Both support CSS custom properties via :root variables. Set fill='var(--icon-color)' in the SVG and toggle the CSS variable in your theme switcher — works identically in Vue and Svelte.
Can I use the same SVG components in both a Vue app and a Svelte app?+
Not directly — the file formats differ. Generate separate Vue and Svelte versions from the same SVG source using the batch API.
Do Vue/Svelte SVG components work with SSR?+
Yes. Both Nuxt 3 and SvelteKit support SSR. SVG components render as inline HTML on the server, avoiding FOUC that external SVG files can cause.
