# @unocss/transformer-attributify-jsx-babel
<!-- @unocss-ignore -->
Support [valueless attributify](https://github.com/unocss/unocss/tree/main/packages/preset-attributify#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-babel
```
```ts
// uno.config.js
import { defineConfig, presetAttributify } from 'unocss'
import transformerAttributifyJsx from '@unocss/transformer-attributify-jsx-babel'
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.
```js
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>
```
