widths: [48, 96],

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')Check the example for additional usage information and different preset examples, or see it live.
