Vue components

vite-plugin-svg-spritemap allows you to load icons and create <use> as <svg> and <view> as <img> tags like Vue components.

To do that, import the icons loaded by vite-svg-spritemap and add the ?use or ?view query. The plugin will transform the component.

<script setup lang="ts">
import SpiriitUse from './icons/spiriit.svg?use'
import SpiriitView from './icons/spiriit.svg?view'
import ViteUse from './icons/vite.svg?use'
import ViteView from './icons/vite.svg?view'
</script>

<template>
  <SpiriitUse>
    <!-- You can use the slot to pass a title before the use tag generation -->
    <title>My superb logo</title>
  </SpiriitUse>
  <ViteUse />

  <SpiriitView />
  <ViteView />
</template>

will generate

<svg>
  <title>My superb logo</title>
  <use xlink:href="/__spritemap#sprite-spiriit"></use>
</svg>
<svg>
  <use xlink:href="/__spritemap#sprite-vite"></use>
</svg>
<img src="/__spritemap#sprite-spiriit-view" width="118" height="38">
<img src="/__spritemap#sprite-vite-view" width="31" height="32">

You can see the usage in the corresponding demo folder.

TypeScript

For TypeScript, you need to load the type definitions inside vite-env.d.ts to fix errors with ?use/?view query.

/// <reference types="vite/client" />
/// <reference types="@spiriit/vite-plugin-svg-spritemap/client" />

Type-safe icon props

You can use the types option to generate TypeScript types for all your icons, allowing you to type your icon props for better type safety.

// vite.config.ts
import VitePluginSvgSpritemap from '@spiriit/vite-plugin-svg-spritemap'

export default {
  plugins: [
    VitePluginSvgSpritemap('./assets/icons/*.svg', {
      types: 'src/types/spritemap.d.ts',
    }),
  ],
}

Then use the generated types in your Vue components. For example, with a reusable Icon component:

<script lang="ts" setup>
import type { Icons } from './types/spritemap'

const props = defineProps<{
  name?: Icons
}>()

const Icon = computed(() => {
  return props.name
    ? defineAsyncComponent(() => import(`assets/icons/${props.name}.svg?use`))
    : null
})
</script>

<template>
  <component :is="Icon" v-if="name" :class="`icon icon-${name}`">
    <slot />
  </component>
</template>

Now the name prop is type-safe and will only accept valid icon names from your spritemap. TypeScript will provide autocomplete and catch invalid icon names at compile time.

Nuxt 3/4

NOTE

This plugin only works with Nuxt 3/4 and Vite as a bundler.

You just need to install the plugin and set it in the right place for Nuxt 3.

// nuxt.config.ts
import VitePluginSvgSpritemap from '@spiriit/vite-plugin-svg-spritemap'

export default defineNuxtConfig({
  vite: {
    plugins: [
      VitePluginSvgSpritemap('./assets/icons/*.svg'),
    ]
  }
})

You can see the usage in the corresponding demo folder.

HMR support

The injection of the HMR script is not supported on Nuxt. You should add it manually by adding <script type="module" src="/_nuxt/@vite-plugin-svg-spritemap/client"></script> on development only.

// nuxt.config.ts
export default defineNuxtConfig({
  $development: {
    app: {
      head: {
        script: [
          { src: '/_nuxt/@vite-plugin-svg-spritemap/client', type: 'module' },
        ],
      },
    },
  },
})

Improve Nuxt performance

You can improve performance by removing one instance of the plugin by using enable the viteEnvironmentApi option. This Nuxt option is available since Nuxt 4.2 and will be activated by default in Nuxt 5.

This will also remove the log pollution in the console.

IMPORTANT

On some setup this option can cause issues with plugins. Test your project with this option to ensure it works as expected.

TypeScript

For usage with TypeScript, you will need to add in a .d.ts file the reference type to use the ?use/?view query.

/// <reference types="@spiriit/vite-plugin-svg-spritemap/client" />
