使用vue-cli编写vue插件

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
