See how to encapsulate an automated registration global component in Vue

In this article, let’s take a look at how to encapsulate an automated registration global component in Vue. I hope it will be helpful to everyone!

During the project development process, we often encapsulate some commonly used global components. However, every time you add a component, you need to manually introduce registration in main.js, which is not only troublesome but also requires a lot of code, which is really annoying. So simply encapsulate an automated registration global component. [Related recommendations: "vue.js Tutorial"]

1. Customize the global component folder

Create a new one under srcglobalComponents, used to store global components and create a new component, such as Orange;

2. Component automatic registration configuration File

Create an index.js in globalComponents to find all components and automatically register

// 自动注册全局组件，每次新增组件必须重新编译
import Vue from 'vue'

const requireComponent = require.context(
  '../globalComponents', // 其组件目录的相对路径
  true, // 是否查询其子目录
  /\.vue$/ // 匹配基础组件文件名的正则表达式
)
requireComponent.keys().forEach(fileName => {
  const componentConfig = requireComponent(fileName); // 获取组件配置
  /**
   * 兼容 import export 和 require module.export 两种规范
   */
  // 如果这个组件选项是通过 export default 导出的,就会优先使用 .default
  const comp = componentConfig.default || componentConfig; 
  Vue.component(comp.name, comp) // 此处的name是组件属性定义的name
})

3. Edit Orange/index. vue

The most important thing about the component is the name defined by the component attribute (name is the automatically registered component name)

<template>
  <div class="wrapper">
    Orange
  </div>
</template>

<script>
export default {
  name: &#39;Orange&#39;, // 此处的name属性值将为后面使用的组件名 <orange />，需唯一
  components: {},
  props: {},
  data() {
    return {}
  },
  created() {},
  mounted() {},
  methods: {}
}
</script>

4. Import globalComponents/ into the entry file main.js index.js

// main.js

import Vue from 'vue'
// 自动注册全局组件
import './globalComponents/index.js'

• After basically completing the above steps, you are done. You can then use this global component directly~
• Usage method:

<template>
  <div class="wrapper">
    <!-- 自动注册的全局组件 -->
    <orange />
  </div>
</template>
