unocss-preset-weapp
相较于 tailwindcss 和 windicss, unocss的性能和可扩展性都优于它们
UnoCSS小程序预设 unocss-preset-weapp
内置 transformer
用于兼容小程序
- transformerClass 转换转义类名,解决小程序不支持
`\\`,`\:`,`\[`, `\$`,`\.`
等转义类名,保持原子化css
的规范去书写class
- transformerAttributify,用于支持 attributify mode

修改 w h 默认单位
unocss-preset-weapp,wh默认单位 `rpx`,例如
.text-20 {
font-size: 20rpx;
}
.h-10 {
height: 10rpx;
}
.top-10 {
top: 10rpx;
}
设置whRpx
为false
,修改默认单位,按rem
规则递增
- unocss.config.ts
import presetWeapp from 'unocss-preset-weapp'
export default defineConfig({
presets: [
presetWeapp({
whRpx: false,
}),
],
})
.text-20 {
font-size: 160rpx;
}
.h-10 {
height: 80rpx;
}
.top-10 {
top: 160rpx;
}
自定义转换规则
如需更改默认的转换规则,可通过
transformRules
进行修改
- unocss.config.js
import presetWeapp from 'unocss-preset-weapp'
import { extractorAttributify, transformerClass } from 'unocss-preset-weapp/transformer'
import { defineConfig } from 'unocss'
const transformRules = {
'.': '-d111-',
'/': '-s111-',
':': '-c111-',
'%': '-p111-',
'!': '-e111-',
'#': '-w111-',
'(': '-b111l-',
')': '-b111r-',
'[': '-f111l-',
']': '-f111r-',
'$': '-r111-',
',': '-r222-',
}
const { presetWeappAttributify, transformerAttributify } = extractorAttributify({
transformRules
})
export default defineConfig({
presets: [
// https://github.com/MellowCo/unocss-preset-weapp
presetWeapp({
transformRules,
}),
// attributify autocomplete
presetWeappAttributify()
],
transformers: [
// options 见https://github.com/MellowCo/unocss-preset-weapp/tree/main/src/transformer/transformerAttributify
transformerAttributify({
transformRules,
}),
// options 见https://github.com/MellowCo/unocss-preset-weapp/tree/main/src/transformer/transformerClass
transformerClass({
transformRules,
}),
],
})
原子化 css 冲突问题
例如 tmui,自身有一套 原子化 css,导致与 unocss 冲突
- unocss.config.ts
presetWeapp
配置prefix
,transformerAttributify
配置classPrefix
import presetWeapp from 'unocss-preset-weapp'
import { extractorAttributify, transformerClass } from 'unocss-preset-weapp/transformer'
import { defineConfig } from 'unocss'
const prefix = 'li-'
const { presetWeappAttributify, transformerAttributify } = extractorAttributify({
classPrefix: prefix
})
export default defineConfig({
presets: [
// https://github.com/MellowCo/unocss-preset-weapp
presetWeapp({
prefix
}),
// attributify autocomplet
presetWeappAttributify()
],
transformers: [
// options 见https://github.com/MellowCo/unocss-preset-weapp/tree/main/src/transformer/transformerAttributify
transformerAttributify(),
// options 见https://github.com/MellowCo/unocss-preset-weapp/tree/main/src/transformer/transformerClass
transformerClass(),
],
})
这样冲突问题就解决了

计算方式
indent-2
原为 text-indent: 0.5rem
等于 8px
,
小程序使用 750rpx
的基准是 2倍px
等于 16rpx
,
所以计算为 2*0.5*1rem = 2*0.5*16px = 16rpx
