风格指南

当你掌握一门语言的时候，在写项目之前不妨先看看风格指南吧，前人早为你铺好了路。下面是我自己编写项目代码时没有规范到位的几个点。

风格指南 — Vue.js (vuejs.org)

Prop 定义

Prop 定义应该尽量详细，至少需要指定其类型。Props | Vue.js (vuejs.org)

Vue的选项式API为我们提供了Prop校验，你可以向 props 选项提供一个带有 props 校验选项的对象,当 prop 的校验失败后，Vue 会抛出一个控制台警告 (开发模式)。（如果用ts的话更好）

注意 prop 的校验是在组件实例被创建之前，所以实例的属性 (比如 data、computed 等) 将在 default 或 validator 函数中不可用。

v-for和v-if同时在一个标签时，将v-if提取到计算属性

因为 v-for 优先级比 v-if 高，所以每次渲染时必定会遍历数组所有元素。避免 v-if 和 v-for 用在一起

将v-if提取到计算属性后的好处

过滤后的列表只会在对应数组发生相关变化时才被重新运算，过滤更高效。
使用 v-for="item in afterComputed" 之后，在渲染的时候遍历元素少了，渲染更高效。
解耦渲染层的逻辑，可维护性 (对逻辑的更改和扩展) 更强。

紧密耦合的组件名

和父组件紧密耦合的子组件应该以父组件名作为前缀命名。紧密耦合的组件名

如果一个组件只在某个父组件的场景下有意义，这层关系应该体现在其名字上。因为编辑器通常会按字母顺序组织文件，所以这样做可以把相关联的文件排在一起。

不建议为了紧密耦合搞目录区分，因为会出现文件名名字相同、IDE侧边栏浏览组件花费时间多的问题。

components/
|- TodoList.vue
|- TodoListItem.vue
|- TodoListItemButton.vue

自闭合组件

在单文件组件、字符串模板和 JSX 中没有内容的组件应该是自闭合的——但在 DOM 模板里永远不要这样做。 自闭合组件

<!-- 在单文件组件、字符串模板和 JSX 中 -->
<MyComponent/>

<!-- 在 DOM 模板中 -->
<my-component></my-component>

Prop 名大小写

在声明 prop 的时候，其命名应该始终使用 camelCase，而在模板和 JSX 中应该始终使用 kebab-case。 Prop 名大小写

props: {
  greetingText: String
}

<WelcomeMessage greeting-text="hi"/>

简单的计算属性

应该把复杂计算属性分割为尽可能多的更简单的 property。 简单的计算属性

好处是易于测试、易于阅读、更好的“拥抱变化”。

单文件组件的顶级元素的顺序

单文件组件应该总是让 <script>、<template> 和 <style> 标签的顺序保持一致。且 <style> 要放在最后，因为另外两个标签至少要有一个。单文件组件的顶级元素的顺序

隐性的父子组件通信

应该优先通过 prop 和事件进行父子组件之间的通信，而不是 this.$parent 或变更 prop。 隐性的父子组件通信

数据流应该是单向的，不要反向修改 props。

方便调试

为了方便调试，我们在 index.css 下新增一个样式组合，通过添加test类样式类看到块元素的边框。

  .test{
    @apply border border-gray-900
  }

网站顶部组件-topbarvue" tid="tid-pKafw3">网站顶部组件 TopBar.vue

在 src/components/common 下新建 TopBar.vue，并移入之前写的 BottomBar.vue。

先从网站顶部开始，该组件在每个页面都会显示，并在滚动过程中固定定位。

编写代码，实现顶部栏。

<template>
  <div class="h-12 shadow-md">
    <div class="inline-block h-full w-16">
      <b-icon-list class="text-3xl mt-2 ml-4"></b-icon-list>
    </div>
    <div class="inline-block h-full w-48">
      <img src="@/assets/logo/logo3.png" class="mt-1 h-4/5 w-full" />
    </div>
    <div class="inline-block float-right mt-2.5 mr-4">
      <div
        class="
          border-2 border-gray-300
          px-3.5
          py-0.5
          rounded-sm
          text-sm
          font-bold
        "
      >
        Log in
      </div>
    </div>
  </div>
</template>

侧边导航栏组件 SideBar.vue

注释底部导航栏

我的Vue之旅、05 导航栏、登录、注册 (Mobile) - 小能日记 - 博客园 (cnblogs.com)

在前一期内容中，我们创建的导航栏是底部导航栏。

现在我们推倒重来，实现一下侧边导航栏。

侧边栏导航也叫抽屉式导航是隐藏在界面侧边的位置，一般是通过点击界面左上角的icon弹出，主要承载的内容是除了核心功能意外的主要功能。侧边栏还分全侧边和半侧边。

当我们在App.vue中注释掉现有的底部导航栏，此时会出现错误item.routerName => item对象的类型为 "unknown"。

<template>
  <router-view @set-bottom-flag="setBottomFlag" />
  <!-- <BottomBar v-show="bottomFlag" :items="bottomItems" /> -->
</template>


<script lang="ts">
import { defineComponent } from "vue";
// import BottomBar from "@/components/BottomBar.vue";

export default defineComponent({
  name: "App",
  components: {
    // BottomBar,
  }
  ...

[TS]使用高级类型PropType注释props类型

IDE报错并不影响当前Vue实例，因为BottomBar组件并未挂载。但为了去除报错，使用高级类型注释来修改BottomBar.vue。

运行时 props 选项仅支持使用构造函数来作为一个 prop 的类型，没有办法指定多层级对象或函数签名之类的复杂类型。在这里可以使用 PropType 注释复杂的props类型，报错解决。

<script lang="ts">
import { PropType } from "vue";

interface BottomItem {
  text: string;
  icon: string;
  routerName: string;
}
export default {
  props: {
    items: {
      type: Array as PropType<BottomItem[]>,
      required: true,
    },
  },
};
</script>

SideBarHref.vue

在 src/components/common 下新建 SideBarHref.vue

侧边导航栏有相似之处，不妨将这一块提取成独立的组件，然后复用三次。

添加样式 hover:text-rose-500 hover:underline，在移动端按下时会改变颜色。

<a :href="value.href">用于临时超链接占位，后续可改为router-link

<template>
  <div class="mt-8 mx-2">
    <div class="font-bold text-stone-700 text-sm">{{ items.title }}</div>
    <div class="w-full text-stone-600 mt-2 text-sm">
      <template v-for="(value, index) in items.items" :key="index">
        <a :href="value.href">
          <div
            class="
              py-1
              inline-block
              w-1/2
              align-middle
              hover:text-rose-500 hover:underline
            "
            v-html="value.text"
          ></div>
        </a>
      </template>
    </div>
  </div>
</template>

<script lang="ts">
import { PropType } from "vue";

interface item {
  text: string;
  href: string;
}

interface items {
  items: item[];
  title: string;
}

export default {
  name: "SideBarHref",
  props: {
    items: { type: Object as PropType<items>, required: true },
  },
};
</script>

SideBar.vue

遮蔽层

在 src/components/common 下新建 SideBar.vue 以下代码片段均为分段表示，不是完整代码。

先写model层（遮蔽层），一般指侧边栏滚出后背景变黑的部分。

我们使用自定义类名实现过渡动画。类名也是TailWind.css的类样式，给定200毫秒时间，过渡透明度状态。

div嵌套了两层，把opacity-50写到里面的div层能解决opacity-50在外面div层的时候出现背景全黑问题。

fixed 用于固定遮蔽层。z-30用于设置优先级，先显示在前面。v-show由App.vue传入，顶部组件通知App.vue事件对应的方法修改，进而引发当前transition的过渡。

html - Vue Transition with Tailwind - Stack Overflow

<template>
  <transition
    enter-active-class="duration-200"
    enter-from-class="opacity-0"
    enter-to-class="opacity-100"
    leave-active-class="duration-200"
    leave-to-class="opacity-0"
    leave-from-class="opacity-100"
  >
    <div class="fixed z-30 h-full w-full" v-show="showFlag" id="model">
      <div class="bg-black h-full w-full opacity-50"></div>
    </div>
  </transition>

侧边栏

侧边栏的动画效果跟遮蔽层一个原理，只不过修改成为了移动而不是改变透明度。

overflow-auto 可以让侧边栏在内容溢出时具备滚动条。

 <transition
    enter-active-class="duration-200 ease-out"
    enter-from-class="-translate-x-64"
    enter-to-class="translate-x-0"
    leave-active-class="duration-200 ease-in"
    leave-from-class="translate-x-0"
    leave-to-class="-translate-x-64"
  >
   <div
      class="fixed z-40 top-12 w-64 h-full bg-stone-100 border-r overflow-auto"
      v-show="showFlag"
      id="sideBar"
    >

搜索框

focus:outline-none focus:ring focus:border-blue-200当当前光标指向该input标签时更改样式，让四角发光变蓝。该段代码也可以提取成基本组件。

      <div class="mt-3 mx-2">
        <input
          id="search"
          class="
            bg-white
            focus:outline-none focus:ring focus:border-blue-200
            py-1.5
            pl-3
            w-full
            border border-gray-300
            text-sm
          "
          type="text"
          placeholder="Search games & creators"
          v-model="search"
        />
      </div>

SideBarHref

三次复用之前定义的SideBarHref组件，并传入了props

      <SideBarHref :items="popularTags"></SideBarHref>
      <SideBarHref :items="browse"></SideBarHref>
      <SideBarHref :items="gamesByPrice"></SideBarHref>

download app

让图标和下载超链接完全数据化，增加网页动态变化能力。

      <div class="h-20 text-center">
        <div class="pt-6">
          <template v-for="(value, index) in appInfo.apps" :key="index">
            <a :href="value.href">
              <component
                :is="value.icon"
                class="inline m-1 text-xl hover:text-rose-500"
              ></component>
            </a>
          </template>
          <a :href="appInfo.download.href">
            <span
              class="
                text-xs text-stone-800
                mx-2
                hover:text-rose-500 hover:underline
              "
              >{{ appInfo.download.title }}</span
            >
          </a>
        </div>
      </div>

数据驱动

除非结构要改，现在完全可以靠data里的对象数据驱动当前侧边栏的所有内容。

  data() {
    return {
      search: "",
      popularTags: {
        title: "POPULAR TAGS",
        items: [
          { text: "Horror games", href: "" },
          { text: "Multiplayer", href: "" },
          { text: "Visual novels", href: "" },
          { text: "HTML5 games", href: "" },
          { text: "Simulation", href: "" },
          { text: "macOS games", href: "" },
          { text: "Roguelike", href: "" },
          { text: "Linux games", href: "" },
          { text: "Browse all tags", href: "" },
        ],
      },
      browse: {
        title: "BROWSE",
  ....

联动顶部组件与侧边导航栏组件

我们的想法是按下顶部组件左边的 list icon，弹出导航栏，再按一次关闭导航栏。

很容易想到父子通信的解决方案，这也是Vue单向数据流的最佳实现。

<template>
  <TopBar @changeSideFlag="changeSideFlag"></TopBar>
  <SideBar :show-flag="sideFlag"></SideBar>
  <div class="absolute top-12 w-full z-10">
    <router-view />
  </div>
</template>

<script lang="ts">
import { defineComponent } from "vue";
import TopBar from "./components/common/TopBar.vue";
import SideBar from "./components/common/SideBar.vue";

export default defineComponent({
  name: "App",
  components: {
    TopBar,
    SideBar,
  },
  data() {
    return {
      sideFlag: false as boolean,
    };
  },
  methods: {
    changeSideFlag(): void {
      this.sideFlag = !this.sideFlag;
    },
  },
});
</script>

[TS]defineComponent 作用

App.vue 里的 export default defineComponent({ 是什么？

搭配 TypeScript 使用 Vue | Vue.js (vuejs.org)

defineComponent 是TypeScript独有的，可以根据选项式API的props、data自动推导各个字段的类型，当在生命周期函数、Methods函数、模板表达式中使用这些字段时可以进行类型检查。（不显式引入编译器默认自动引入）

TopNavigation

overflow-x-auto flex flex布局，并在溢出时开启横轴滚动条

whitespace-nowrap 类可以防止换行，让所有元素保持在一行上。

GameInfo.vue

嵌入YOUTUBE视频可参考 youtubeembedcode.com

      <div class="w-full">
        <img :src="currentImg[0]" class="w-1/2 inline-block" />
        <img :src="currentImg[1]" class="w-1/2 inline-block" />
      </div>

用于生成两张轮播图，每四秒切换一次，具体方法如下。注意 currentImg: function (): string[] { 可以给计算属性添加类型检查。

  methods: {
    startSlide: function (): void {
      this.timer = setInterval(this.next, 4000);
    },

    next: function (): void {
      this.currentIndex += 1;
    },
  },
  computed: {
    currentImg: function (): string[] {
      let index = Math.abs(this.currentIndex) % this.gameInfo.images.length;
      let index2 = (index + 1) % this.gameInfo.images.length;
      return [this.gameInfo.images[index], this.gameInfo.images[index2]];
    },
  },

考虑 img 标签的 :src 只能接收 string ，我们假设所有 require 方法获取的图片均为 string 类型。定义prop类型

import { PropType } from "vue";

interface GameInfo {
  youtube: string;
  title: string;
  desc: string;
  price: number;
  platforms: string[];
  images: string[];
}

GameList.vue

规定了比较复杂的传入prop类型，考虑到tags可能为空，在原来的模板外层div做v-if判断，否则会ts报错value.tags可能为undefined。

interface Game {
  title: string;
  text: string;
  img: string;
  price: number;
  web?: boolean;
  tags?: string[];
}

interface GameList {
  title: string;
  button: {
    title: string;
    href: string;
  };
  games: Game[];
}

<div class="text-xs font-normal mt-1" v-if="value.tags">
  <template v-for="(tag, index) in value.tags" :key="index">
    <a class="text-rose-500" href="">#{{ tag }}</a>
    <template v-if="index != value.tags.length - 1">,</template>

几个问题

这里列举我在开发过程遇到的一些问题，也许能帮助到你。

ERROR Error: The project seems to require yarn but it's not installed.

明明 yarn serve 成功了，并显示如下内容，但连接网页还是转圈圈。尝试重启电脑后重新 yarn serve

  App running at:
  - Local:   http://localhost:8080/

得到如下报错

 ERROR  Error: The project seems to require yarn but it's not installed.

解决方法：删除当前目录下的 yarn.lock 文件，命令行输入 npm install -g yarn

Type assertion expressions can only be used in TypeScript files.Vetur(8016)

解决方法：修改 <script> 为 <script lang="ts">
