本文主要介绍了使用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

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 Toastnpm 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>

<p id="app">

<p class="demo-box">
<button @click="test">默认效果</button>
</p>

<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
