各端如何消费
Section titled “各端如何消费”share 的 core 是纯函数,不含任何响应式。各端 UI 库只做一件事:把纯函数的输出绑到 模板,把用户的输入喂回纯函数。下面是四端的接线形态。
每个组件的接线都是这三步:
- 框架侧持有一份 state(
ref/useState/ 响应式 data) - 用户交互 → 调 core 纯函数算出新 state → 写回
- 模板里调类名 / aria 属性包纯函数渲染
// core 侧(框架无关,本仓)export function getSwitchClasses(state: LhSwitchState): stringexport function getSwitchAria(state: LhSwitchState): Record<string, string>export function toggleSwitch(state: LhSwitchState, checked: boolean): LhSwitchStateVue3(lh-ui-plus)
Section titled “Vue3(lh-ui-plus)”<script setup lang="ts">import { ref, computed } from 'vue'import { getSwitchClasses, getSwitchAria, toggleSwitch } from '@lh-ui/share/core/switch'
const checked = ref(false)const classes = computed(() => getSwitchClasses({ checked: checked.value, disabled: false }))const aria = computed(() => getSwitchAria({ checked: checked.value }))
function onToggle() { checked.value = toggleSwitch({ checked: checked.value }, !checked.value).checked}</script>
<template> <button :class="classes" v-bind="aria" @click="onToggle"> <span class="lh-switch__handle" /> </button></template>
<style lang="scss">@use '@lh-ui/share/styles/switch';</style>样式在库入口全量 side-effect 注入,组件里一般不用自己引(见注入策略)。
Vue2(lh-ui-vue2)
Section titled “Vue2(lh-ui-vue2)”<script lang="ts">import { getSwitchClasses, getSwitchAria, toggleSwitch } from '@lh-ui/share/core/switch'
export default { name: 'LhSwitch', data() { return { checked: false } }, computed: { classes() { return getSwitchClasses({ checked: this.checked, disabled: false }) }, aria() { return getSwitchAria({ checked: this.checked }) }, }, methods: { onToggle() { this.checked = toggleSwitch({ checked: this.checked }, !this.checked).checked }, },}</script>样式需用户按需引:
import '@lh-ui/vue2/theme.css'import '@lh-ui/vue2/style/switch'React(lh-ui-react)
Section titled “React(lh-ui-react)”useMemo 替代 computed;state 变化触发重渲染天然是响应式的:
import { memo, useMemo, useState } from 'react'import { getSwitchClasses, getSwitchAria, toggleSwitch,} from '@lh-ui/share/core/switch'import '@lh-ui/react/style/switch'
export const LhSwitch = memo(function LhSwitch() { const [checked, setChecked] = useState(false)
const classes = useMemo( () => getSwitchClasses({ checked, disabled: false }), [checked], ) const aria = useMemo(() => getSwitchAria({ checked }), [checked])
return ( <button type="button" className={classes} {...aria} onClick={() => setChecked((c) => !c)} > <span className="lh-switch__handle" /> </button> )})uniapp(lh-ui-uniapp)
Section titled “uniapp(lh-ui-uniapp)”uniapp 的 <view> / <text> 上不能随意绑 aria 属性,getSwitchAria 的产物在
小程序端会被过滤;app / h5 端仍可用。类名绑定走 :class 字符串或数组:
<template> <view :class="classes" @tap="onToggle"> <view class="lh-switch__handle" /> </view></template>
<script setup lang="ts">import { ref, computed } from 'vue'import { getSwitchClasses, toggleSwitch } from '@lh-ui/share/core/switch'
const checked = ref(false)const classes = computed(() => getSwitchClasses({ checked: checked.value }))function onToggle() { checked.value = !checked.value}</script>国际化:同一个 emitter,四种订阅
Section titled “国际化:同一个 emitter,四种订阅”LhLocale 是纯事件发射器,version 在任何语言变更时自增。各端把它转成各自的重渲染信号:
| 端 | 接线 |
|---|---|
| vue2 / vue3 / uniapp | ref(lhlocale.version) + lhlocale.subscribe(v => version.value = v) |
| react | useSyncExternalStore(lhlocale.subscribe, () => lhlocale.version) |
import { lhlocale } from '@lh-ui/share/locales'
lhlocale.setLocale('en-US') // 切换,version 自增并广播const text = lhlocale.t('input.placeholder')实时演示见国际化参考。
本地联动:改 share 源码即时生效
Section titled “本地联动:改 share 源码即时生效”家族布局下,各 UI 库的 dev / test 配置 alias 到同级 lh-ui-share/,dev 期走的是
TS / SCSS 源码而非构建产物。新增深文件(如 core/foo/bar.ts)在 dev 期立即可用,
但 sync-exports 未跑则 npm 侧没有对应 exports 键——发版前务必走完整 pnpm build,
否则下游 pnpm up 后 MODULE_NOT_FOUND。
