Installation

Requirements

Peer dependency	Version	Required
vue	^3.0.0	yes
sharp	>=0.33.0	only for the CLI / Vite plugin / self-hosted server
thumbhash	>=0.1.0	only for the CLI's --thumbhash flag and the Vite plugin's ?thumbhash/?vik build-time imports

Everything that runs in the browser — decodeThumbHash(), the thumbhash prop on VImage, and the client-side encodeThumbHash()/encodeBlurhash() encoders — is a dependency-free, in-house implementation. sharp/thumbhash are only needed for the Node-side tooling that processes images ahead of time.

Installation

npm install @macrulez/vue-image-kit

Peer dependency:

npm install vue@>=3.0

sharp and thumbhash are optional peer dependencies — install them only if you use the CLI, the Vite plugin, or the self-hosted server:

npm install sharp thumbhash --save-dev

Quick start — Vue 3

1. Register the plugin

// main.ts
import { createApp } from 'vue'
import { VImageKitPlugin } from '@macrulez/vue-image-kit'
import App from './App.vue'

const app = createApp(App)
app.use(VImageKitPlugin)
app.mount('#app')

After installation, <VImage> is available in all templates without importing, and v-lazy-img is registered as a global directive.

2. Use the component

<template>
  <VImage
    src="/photo.jpg"
    alt="Mountain landscape"
    :width="1200"
    :height="600"
    blurhash="LEHV6nWB2yk8pyo0adR*.7kCMdnj"
  />
</template>

<VImage> is registered globally by the plugin. No import needed.

3. Or import explicitly

Skip the plugin and import only what you need — useful if you only want the directive, or a single composable, and want the bundler to tree-shake the rest away:

import {
  VImageKitPlugin, // Vue plugin
  VImage, // component
  vLazyImg, // directive
  useImage, // composable
  useBlurhash, // canvas composable
  useLazyLoad, // IO composable
  decodeBlurhash, // standalone decoder
  generateSrcset, // srcset utility
  generateSizes, // sizes utility
} from '@macrulez/vue-image-kit'

<script setup lang="ts">
import { VImage } from '@macrulez/vue-image-kit'
</script>

<template>
  <VImage src="/photo.jpg" alt="My photo" />
</template>

Quick start — Nuxt 3

1. Add the module to nuxt.config.ts

// nuxt.config.ts
export default defineNuxtConfig({
  modules: ['@macrulez/vue-image-kit/nuxt'],
  vueImageKit: {
    breakpoints: {
      sm: '(max-width: 640px)',
      md: '(max-width: 1024px)',
    },
  },
})

2. Use in pages and components — everything is auto-imported

<template>
  <VImage
    :src="{ avif: '/hero.avif', webp: '/hero.webp', fallback: '/hero.jpg' }"
    alt="Hero image"
    :width="1920"
    :height="1080"
    :widths="[640, 1024, 1920]"
    sizes="100vw"
    blurhash="LEHV6nWB2yk8pyo0adR*.7kCMdnj"
    :lazy="true"
  />
</template>

<VImage>, v-lazy-img, and all composables are registered automatically — no imports needed. Canvas and IntersectionObserver are activated only on the client — no hydration mismatch.
