如何封装vue组件？

注意：如有不懂可留言，如果我看到尽量回复你！
可以使用npm进行下载使用（本篇文章并未讲解npm上传代码）
npm install ueui
或者
cnpm install ueui

目录结构

• ueui
  • components
    • UeButton
      • button.vue
      • index.js
  • lib
    • theme
      • button.css
      • index.js
  • index.js
  • package.json

components/UeButton/buttn.vue

利用props进行传参判断class样式
	- round 圆角
	- loading 加载 （ps：loading动态图标可自行添加class）
	- disabled 可以度
	- icon 可自定义添加icon
	- nativeType 按钮类型
	- size 按钮大小
	- type 
	  可选参数 primary success info warning danger

可利用<slot></slot>插槽可填写按钮文字或者图标

<template>
  <button
    class="ue-button"
    :class="[{'ue-button-radius': round}, disabled || loading ? `${type}-disabled` : type, size, {'ue-button-disabled':disabled}]"
    :disabled="disabled || loading"
    :type="nativeType"
    @click="handlerClick">
    <i class="" v-if="loading"></i>
    <i :class="icon" v-if="icon && !loading"></i>
    <span v-if="$slots.default"><slot></slot></span>
  </button>
</template>

<script>
  export default {
    name: "UeButton",
    props: {
      round: Boolean,
      loading: Boolean,
      disabled: Boolean,
      type: {
        type: String,
        default: 'default'
      },
      icon: {
        type: String,
        default: ''
      },
      size: {
        type: String,
        default: ''
      },
      nativeType: {
        type: String,
        default: 'button'
      }
    },
    methods: {
      handlerClick(evt) {
        this.$emit('click', evt)
      }
    }
  }
</script>

components/UeButton/index.js

注册button到vue中

import UeButton from './button';
// ...
/* istanbul ignore next */
UeButton.install = function(Vue) {
  Vue.component(UeButton.name, UeButton);
};

export default UeButton;

lib/theme/button.css

lib/theme/index.js

这样写可实现按需引入组件

import "./button.css";

index.js

全部引入方法 按照下方同样的方式引入组件

import UeButton from './components/UeButton';
// ...
const components = [
  UeButton
];

const install = function(Vue) {
  components.forEach(component => {
    Vue.component(component.name, component);
  });
};

/* istanbul ignore if */
if (typeof window !== 'undefined' && window.Vue) {
  install(window.Vue);
}

export default {
  version: '1.0.0',
  install
}

package.json

使用npm生成json文件
  - npm init

  "name": "ueui",
  "version": "1.0.1",
  "description": "",
  "main": "index.js",
  "directories": {
    "lib": "lib"

  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
