Attributify JSX transformer
Support valueless attributify in JSX/TSX: @unocss/transformer-attributify-jsx
.
Presentation
jsx
export function Component() {
return (
<div text-red text-center text-5xl animate-bounce>
unocss
</div>
)
}
export function Component() {
return (
<div text-red text-center text-5xl animate-bounce>
unocss
</div>
)
}
Will be transformed to:
jsx
export function Component() {
return (
<div text-red="" text-center="" text-5xl="" animate-bounce="">
unocss
</div>
)
}
export function Component() {
return (
<div text-red="" text-center="" text-5xl="" animate-bounce="">
unocss
</div>
)
}
Without this transformer, JSX treats valueless attributes as boolean attributes.
jsx
export function Component() {
return (
<div text-red={true} text-center={true} text-5xl={true} animate-bounce={true}>
unocss
</div>
)
}
export function Component() {
return (
<div text-red={true} text-center={true} text-5xl={true} animate-bounce={true}>
unocss
</div>
)
}

Caveats
WARNING
The rules are almost the same as those of Attributify preset, but there are several precautions.
html
<div translate-x-100% /> <!-- cannot end with `%` -->
<div translate-x-[100px] /> <!-- cannot contain `[` or `]` -->
<div translate-x-100% /> <!-- cannot end with `%` -->
<div translate-x-[100px] /> <!-- cannot contain `[` or `]` -->
Instead, you may want to use valued attributes instead:
html
<div translate="x-100%" />
<div translate="x-[100px]" />
<div translate="x-100%" />
<div translate="x-[100px]" />
Blocklist
This transformer will only transform attributes that are valid UnoCSS utilities. You can also blocklist
bypass some attributes from been transformed.
js
transformerAttributifyJsx({
blocklist: [/text-[a-zA-Z]*/, 'text-5xl']
})
transformerAttributifyJsx({
blocklist: [/text-[a-zA-Z]*/, 'text-5xl']
})
jsx
<div text-red text-center text-5xl animate-bounce>
unocss
</div>
<div text-red text-center text-5xl animate-bounce>
unocss
</div>
Will be compiled to:
html
<div text-red text-center text-5xl animate-bounce="">
unocss
</div>
<div text-red text-center text-5xl animate-bounce="">
unocss
</div>
