@unocss/transformer-attributify-jsx

Support valueless attributify in JSX/TSX.

jsx

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>
  )
}

<details> <summary>Without this transformer</summary>

JSX by default will treat 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>
  )
}

</details>

Install

bash

npm i -D @unocss/transformer-attributify-jsx

import transformerAttributifyJsx from '@unocss/transformer-attributify-jsx'
// uno.config.ts
import { defineConfig, presetAttributify } from 'unocss'

export default defineConfig({
  // ...
  presets: [
    // ...
    presetAttributify()
  ],
  transformers: [
    transformerAttributifyJsx(), // <--
  ],
})

Caveats

⚠️ The rules are almost the same as those of preset-attributify, but there are several precautions

html

<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]" />

Blocklist

This transformer will only transform attributes that are valid UnoCSS utilities. You can also blocklist bypass some attributes from been transformed.

transformerAttributifyJsx({
  blocklist: [/text-[a-zA-Z]*/, 'text-5xl']
})

jsx

<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>
