next-svg
Next.js plugin to optimize svg images with SVGO v2. Output can be
used with next/image
by default, or as a React component when imported with a resource query.
The current version generates a thin wrapping component around a svg
<use>
element.
How to install
yarn add @stefanprobst/next-svg`
How to use
Add the plugin to the Next.js configuration:
// next.config.mjs
import createSvgPlugin from '@stefanprobst/next-svg'
/** @type {import('next').NextConfig} */
const nextConfig = {}
const withSvg = createSvgPlugin({
// id: '__root__',
// svgoPlugins: [],
})
export default withSvg(nextConfig)
There are three options for importing an svg image:
Use with next/image
By default, the svg image will be imported for use with next/image
. This is also the default
next
behavior.
import Image from 'next/image'
import RocketAsset from '../public/rocket.svg'
export default function HomePage() {
return (
<main>
<Image src={RocketAsset} alt="Cartoon rocket" />
</main>
)
}
Use as a React component with inlined svg
When used with a ?inline
resource query, the import returns a React component which inlines the
svg as jsx. This is similar to what svgr
does.
import RocketComponent from '../public/rocket.svg?inline'
export default function HomePage() {
return (
<main>
<RocketComponent aria-label="Cartoon rocket" />
</main>
)
}
Alternatively, the ?inline-icon
resource query will add a default width and height of 1em
.
Use as a React component with <use>
When used with a ?symbol
resource query, the import returns a React component which references the
svg image via <use>
.
import RocketComponent from '../public/rocket.svg?symbol'
export default function HomePage() {
return (
<main>
<RocketComponent aria-label="Cartoon rocket" />
</main>
)
}
Alternatively, the ?symbol-icon
resource query will add a default width and height of 1em
.
