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
