Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Uniapp Vue3 Vite Plugin

借助 Vite 模拟出虚拟根组件(支持SFC的App.vue),解决 uniapp 无法使用公共组件问题

NPM version NPM downloads LICENSE

[!TIP] 从 v0.2.0 开始, 已支持 HBuilderX 创建的 Vue3 项目

🎏 支持

  • Uniapp - CLI 或 HBuilderX 创建的 Vue3 项目
  • 自定义虚拟根组件文件命名
  • 更高灵活度的获取虚拟根组件实例

📦 安装

pnpm add -D @uni-ku/root

🚀 使用

  1. 引入 @uni-ku/root
  • CLI: 直接编写 根目录下的 vite.config.*
  • HBuilderX: 需要根据你所使用语言, 在根目录下 创建 vite.config.*
// vite.config.*

import { defineConfig } from 'vite'
import UniKuRoot from '@uni-ku/root'
import Uni from '@dcloudio/vite-plugin-uni'

export default defineConfig({
  plugins: [
    // 若存在改变 pages.json 的插件,请将 UniKuRoot 放置其后
    UniKuRoot(),
    Uni()
  ]
})
  1. 创建 App.ku.vue(可自定义此根组件名称,请下拉至功能参考设置)

通过标签 <KuRootView /><ku-root-view /> 指定视图存放位置,且可以放置到 template 内任意位置,但仅可有一个

该功能与 VueRouter 中的 RouterView 功能类似,但请注意,由于Uniapp-Vue的局限性,该功能并不完全等同于原版 RouterView

  • CLI: 需要在 src目录 下创建下 App.ku.vue (或自定义名称)
  • HBuilderX: 直接在 根目录 下创建 App.ku.vue (或自定义名称)
<!-- src/App.ku.vue | App.ku.vue -->

<script setup lang="ts">
import { ref } from 'vue'

const helloKuRoot = ref('Hello AppKuVue')
</script>

<template>
  <div>{{ helloKuRoot }}</div>
  <!-- 顶级 KuRootView -->
  <KuRootView />

  <!-- 或内部 KuRootView,无论放置哪一个层级都被允许,但仅可有一个! -->
  <div>
    <KuRootView />
  </div>
</template>

🎉 功能

功能一:自定义虚拟根组件名称(默认:App.ku.vue)

  1. 通过设置 vite.config.* 下插件的参数 rootFileName 来自定义虚拟根组件名称
// vite.config.*

import { defineConfig } from 'vite'
import UniKuRoot from '@uni-ku/root'
import Uni from '@dcloudio/vite-plugin-uni'

export default defineConfig({
  plugins: [
    UniKuRoot({
      // 默认含后缀 .vue,直接设置命名即可
      rootFileName: 'KuRoot',
    }),
    // ...other plugins
  ]
})
  1. 创建/修改虚拟根组件为 KuRoot.vue,即可实现自定义,其余功能不变

功能二:使用虚拟根组件实例(即:App.ku.vue)

有两种方法,局部或全部启用,请看一下示例

一、 局部启用

  1. 暴露出 App.ku 里所要被使用的变量或方法
<!-- src/App.ku.vue | App.ku.vue -->

<script setup lang="ts">
import { ref } from 'vue'

const helloKuRoot = ref('Hello AppKuVue')

const exposeRef = ref('this is form app.Ku.vue')

defineExpose({
  exposeRef,
})
</script>

<template>
  <div>
    <div>{{ helloKuRoot }}</div>
    <KuRootView />
  </div>
</template>
  1. 在 template 内编写 root="xxx",并通过 const xxx = ref() 获取模板引用

xxx 代表自定义命名,可以随意命名

<!-- src/pages/*.vue -->

<script setup lang="ts">
import { ref } from 'vue'

const uniKuRoot = ref()
</script>

<template root="uniKuRoot">
  <view>
    Hello UniKuRoot
  </view>
</template>

二、全局启用

  1. 通过配置 enabledGlobalRef 开启全局自动注入 App.ku 实例
// vite.config.*

import { defineConfig } from 'vite'
import UniKuRoot from '@uni-ku/root'
import Uni from '@dcloudio/vite-plugin-uni'

export default defineConfig({
  plugins: [
    UniKuRoot({
      enabledGlobalRef: true
    }),
    Uni()
  ]
})
  1. 暴露出 App.ku 里所要被使用的变量或方法
<!-- src/App.ku.vue | App.ku.vue -->

<script setup lang="ts">
import { ref } from 'vue'

const helloKuRoot = ref('Hello UniKuRoot')

const exposeRef = ref('this is from App.ku.vue')

defineExpose({
  exposeRef,
})
</script>

<template>
  <div>
    <div>{{ helloKuRoot }}</div>
    <KuRootView />
  </div>
</template>
  1. 通过特有内置方法 getCurrentPages() 获取暴露的数据
<!-- src/pages/*.vue -->

<script setup lang="ts">
import { onMounted, ref } from 'vue'

const pagesStack = getCurrentPages()
const uniKuRoot = ref()

onMounted(() => {
  uniKuRoot.value = pagesStack[pagesStack.length - 1].$vm.$refs.uniKuRoot
})
</script>

<template>
  <view>
    Hello UniKuRoot
  </view>
</template>

✨ 例子

以下例子均以CLI创建项目为例, HBuilderX 项目与以上设置同理, 只要注意是否需要包含 src目录 即可

不仅是 Toast 组件,还可以是 Message、LoginPopup 等等

  1. 编写 Toast 组件
<!-- src/components/GlobalToast.vue -->

<script setup lang="ts">
import { useToast } from '@/composables/useToast'

const { globalToastState, hideToast } = useToast()
</script>

<template>
  <div v-if="globalToastState" class="toast-wrapper" @click="hideToast">
    <div class="toast-box">
      welcome to use @uni-ku/root
    </div>
  </div>
</template>

<style scoped>
.toast-wrapper{
  position: fixed;
  top: 0;
  left: 0;
  width: 100%;
  height: 100%;
  background-color: rgba(0, 0, 0, 0.5);
  display: flex;
  align-items: center;
  justify-content: center;
}

.toast-box{
  background: white;
  color: black;
}
</style>
  1. 实现 Toast 组合式API
// src/composables/useToast

import { ref } from 'vue'

const globalToastState = ref(false)

export function useToast() {
  function showToast() {
    globalToastState.value = true
  }

  function hideToast() {
    globalToastState.value = false
  }

  return {
    globalToastState,
    showToast,
    hideToast,
  }
}
  1. 挂载至 App.ku.vue
<!-- src/App.ku.vue -->

<script setup lang="ts">
import GlobalToast from '@/components/GlobalToast.vue'
</script>

<template>
  <KuRootView />
  <GlobalToast />
</template>
  1. 视图内部触发全局 Toast 组件
<!-- src/pages/*.vue -->

<script setup lang="ts">
import { useToast } from '@/composables/useToast'

const { showToast } = useToast()
</script>

<template>
  <view>
    Hello UniKuRoot
  </view>
  <button @click="showToast">
    视图内触发展示Toast
  </button>
</template>

不仅仅只有ConfigProvider,还能是Layout、NavBar、TabBar等等!

  1. 以 Wot 组件库中 WdConfigProvider 为例子,了解更多Wot点这里
<!-- src/App.ku.vue -->

<script setup lang="ts">
import { useTheme } from './composables/useTheme'

const { theme, themeVars } = useTheme({
  buttonPrimaryBgColor: '#07c160',
  buttonPrimaryColor: '#07c160'
})
</script>

<template>
  <div>Hello AppKuVue</div>
  <!-- 假设已注册 WdConfigProvider 组件 -->
  <WdConfigProvider :theme="theme" :theme-vars="themeVars">
    <KuRootView />
  </WdConfigProvider>
</template>
  1. 编写主题相关组合式API
// src/composables/useTheme.ts

import type { ConfigProviderThemeVars } from 'wot-design-uni'
import { ref } from 'vue'

const theme = ref<'light' | 'dark'>(false)
const themeVars = ref<ConfigProviderThemeVars>()

export function useTheme(vars?: ConfigProviderThemeVars) {
  vars && (themeVars.value = vars)

  function toggleTheme(mode?: 'light' | 'dark') {
    theme.value = mode || (theme.value === 'light' ? 'dark' : 'light')
  }

  return {
    theme,
    themeVars,
    toggleTheme,
  }
}
  1. 切换主题模式
<!-- src/pages/*.vue -->

<script setup lang="ts">
import { useTheme } from '@/composables/useTheme'

const { theme, toggleTheme } = useTheme()
</script>

<template>
  <button @click="toggleTheme">
    切换主题,当前模式:{{ theme }}
  </button>
</template>
