使用vue-cli编写vue插件的方法

利用vue组件创建模板，使用webpack打包生成插件再全局使用

1、vue init webpack-simple 生成项目目录

2、调整目录结构

3、修改webpack.config.js

var path = require('path')
var webpack = require('webpack')

module.exports = {
 entry: './src/index.js',
 output: {
  path: path.resolve(__dirname, './dist'),
  publicpath: '/dist/',
  filename: 'vue-toast.js',
  // 打包后的格式（三种规范amd,cmd,common.js)通过umd规范可以适应各种规范，以及全局window属性
  librarytarget:'umd',
 },
 module: {
  rules: [
   {
    test: /\.vue$/,
    loader: 'vue-loader',
   },
   {
    test: /\.js$/,
    loader: 'babel-loader',
    exclude: /node_modules/
   },
   
  ]
 },
 plugins:[]
} 

开发一个toast插件，可以借助npm平台发布，在这里就不做过多的说明了

toast.vue

<template>
 <transition name="toast-fade">
  <div class="toast"
   :class="objclass" 
   v-show="isactive"
   @mouseenter="onmouseenter"
   @mouseleave="onmouseleave"
   >
   <button class="toast-close-button" @click="hide">×</button>
   <div class="toast-container">
    <div class="toast-title">{{title}}</div>
    <div class="toast-content">{{content}}</div>
   </div>
  </div>
 </transition>
</template>

<script>
export default {
 data: () => ({
  list: [],
  title: null,
  content: null,
  type: null,
  isactive: false,
  timer: null,
  onshow: () => {},
  onhide: () => {}
 }),
 computed: {
  objclass () {
   // 样式'success, error, warning, default'
   return this.type ? 'toast-' + this.type : null
  }
 },
 methods: {
  // 显示
  show (params) {
   let {content, title, onshow, onhide, type} = params
   this.type = type
   this.content = content
   this.title = title
   this.onshow = onshow
   this.onhide = onhide

   this.isactive = true
   this.settimer()
  },

  // 隐藏
  hide () {
   this.isactive = false
  },

  // 计时器
  settimer () {
   cleartimeout(this.timer)
   this.timer = settimeout(() => {
    this.isactive = false
   }, 4000)
  },

  // 鼠标移至组件时保持显示状态
  onmouseenter () {
   cleartimeout(this.timer)
  },

  // 鼠标移开组件时重新定时
  onmouseleave () {
   if (this.isactive) this.settimer()
  }
 },
 watch: {
  isactive (val) {
   if (val && typeof this.onshow === 'function') {
    this.onshow()
   } else if (!val && typeof this.onhide === 'function') {
    this.onhide()
   }
  }
 }
}
</script>

index.js

import toastcomponent from './toast.vue'
let toast = {};
toast.install = function(vue, options = {}) {
  // extend组件构造器
  const vuetoast = vue.extend(toastcomponent)
  let toast = null
  function $toast(params) {
    return new promise( resolve => {
      if(!toast) {
        toast = new vuetoast()
        toast.$mount()
        document.queryselector(options.container || 'body').appendchild(toast.$el)
      }
      toast.show(params)
      resolve()
    })
  }
  vue.prototype.$toast = $toast
}
if(window.vue){
  vue.use(toast)
}
export default toast

npm run build 之后就会在根目录下生成dist文件

接下来就可以使用了

demo.html

<!doctype html>
<html lang="en">
<head>
 <meta charset="utf-8">
 <title>title</title>
 <meta name="viewport" content="width=device-width,initial-scale=1.0,maximum-scale=1.0,user-scalable=no">
 <!--引入-->
 <script src="node_modules/vue/dist/vue.js"></script>
 <script src="dist/vue-toast.js"></script>
</head>

<body>
 <div id="app">
  <h1>vue-toast，{{msg}}</h1>
  <div class="demo-box">
   <button @click="test">默认效果</button>
  </div>
 </div>
 <script>
  var vm = new vue({
   el: "#app",
   data: {
    msg: '你好'
   },
   methods: {
    test() {
      this.$toast({
       title:'消息提示',
       content: '您有一条新消息',
       type: 'warning',
       onshow: ()=>{
         console.log('on toast show')
       },
       onhide: ()=>{
         console.log('on toast hide')
       }
     })
    }
   }
  })

 </script>
</body>
</html>

总结：

1、使用vue构造器，通过vue组件来创建一个子类：vue.extend(component)

2、webpack配置output的path必须为绝对路径

3、webpack基础配置：entry,output,module,plugins
