现在的配置这样
```JavaScript
// uno.config.ts
import {
Preset,
defineConfig,
presetAttributify,
presetIcons,
transformerDirectives,
transformerVariantGroup,
} from 'unocss'
import {
presetApplet,
presetRemRpx,
transformerApplet,
transformerAttributify,
} from 'unocss-applet'
const isH5 = process.env?.UNI_PLATFORM === 'h5'
const isMp = process.env?.UNI_PLATFORM?.startsWith('mp') ?? false
const presets: Preset[] = []
if (!isMp) {
/**
* you can add `presetAttributify()` here to enable unocss attributify mode prompt
* although preset is not working for applet, but will generate useless css
* 为了不生产无用的 css,要过滤掉 applet
*/
// 支持 css class 属性化，eg: `<button bg="blue-400 hover:blue-500 dark:blue-500 dark:hover:blue-600" text="sm white">attributify Button</button>`
presets.push(presetAttributify())
}
if (!isH5) {
presets.push(presetRemRpx())
}
export default defineConfig({
presets: [
presetApplet({ enable: !isH5 }),
...presets,
// 支持图标，需要搭配图标库，eg: @
iconify-json/carbon, 使用 `<button class="i-carbon-sun dark:i-carbon-moon" />`
presetIcons({
scale: 1.2,
warn: true,
extraProperties: {
display: 'inline-block',
'vertical-align': 'middle',

],
theme: {},
