Svelte SVG Inline

A tiny Vite plugin that inlines external SVG files at build time.

• No runtime fetching or client JS
• SSR-friendly
• Applies <svg> attributes to the source

vite.config.js:

import { svg } from 'svelte-svg-inline';

export default defineConfig({
    plugins: [svg(/** options */), sveltekit()],
});

    <svg {@attach svg('./image.svg')} fill="currentColor" />

<script lang="ts">
    const fill="red";
</script>

<svg {@attach svg('./image.svg')} {fill}></svg>

Plugin Options

Relative paths resolve relative to the importing .svelte file.

With base option set, absolute paths (started with /) resolve against <project-root>/<base>; relative-path behavior is unchanged. Suitable when all icons located in a single directory.

type Options = {
    base?: string;
};

Typescript

Import attachment types, e.g. app.d.ts:

import 'svelte-svg-inline/dist/attachment.d.ts';

Limitation

The path argument must be a string Literal, not an Identifier or others. Identifier support can be added in a future update.

This code will NOT work:

<script lang="ts">
    import path from './sample.svg';
</script>

<!-- path here is NOT Literal -->
<svg {@attach svg(path)} fill="red"></svg>
