Installation 💿

Configuration ⚙️

Add it to your plugins in vite.config.ts

import { defineConfig } from 'vite'
import imagePresets, { widthPreset } from 'vite-plugin-image-presets'

export default defineConfig({
  plugins: [
    imagePresets({
      thumbnail: widthPreset({
        class: 'img thumb',
        loading: 'lazy',
        widths: [48, 96],
        formats: {
          webp: { quality: 50 },
          jpg: { quality: 70 },
        },
      }),
    }),
  ],
})

Usage 🚀

Use the preset query parameter to obtain an array of source and img attrs:

import thumbnails from '~/images/logo.jpg?preset=thumbnail'

expect(thumbnails).toEqual([
  {
    type: 'image/webp',
    srcset: '/assets/logo.ffc730c4.webp 48w, /assets/logo.1f874174.webp 96w',
  },
  {
    type: 'image/jpeg',
    srcset: '/assets/logo.063759b1.jpeg 48w, /assets/logo.81d93491.jpeg 96w',
    src: '/assets/logo.81d93491.jpeg',
    class: 'img thumb',
    loading: 'lazy',
  },
])

You can also use the src and srcset query parameters for direct usage:

import srcset from '~/images/logo.jpg?preset=thumbnail&srcset'
import src from '~/images/logo.jpg?preset=thumbnail&src'

expect(srcset).toEqual('/assets/logo.063759b1.jpeg 48w, /assets/logo.81d93491.jpeg 96w')
expect(src).toEqual('/assets/logo.81d93491.jpeg')
