使用vue-cli编写vue插件的方法
2020-11-27

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
