1. Initialize the project
vue init webpack-simple npm-vue-ui2. Modify the entry file
{
"name": "npm-vue-ui",
"description": "npm插件库",
"version": "1.0.5",
"author": "gengbigbing",
"license": "MIT",
"private": false, // 插件的话，需要设置为false
"main": "dist/build.js", // 修改这个入口文件
"scripts": {
"dev": "cross-env NODE_ENV=development webpack-dev-server --open --hot",
"build": "cross-env NODE_ENV=production webpack --progress --hide-modules"
},
"dependencies": {
"npm-vue-ui": "^1.0.5",
"vue": "^2.5.11"
},
"browserslist": [
"> 1%",
"last 2 versions",
"not ie <= 8"
],
"devDependencies": {
"babel-core": "^6.26.0",
"babel-loader": "^7.1.2",
"babel-preset-env": "^1.6.0",
"babel-preset-stage-3": "^6.24.1",
"cross-env": "^5.0.5",
"css-loader": "^0.28.7",
"file-loader": "^1.1.4",
"less": "^3.11.1",
"less-loader": "^5.0.0",
"vue-loader": "^13.0.5",
"vue-template-compiler": "^2.4.4",
"webpack": "^3.6.0",
"webpack-dev-server": "^2.9.1"
}
}
3. Modify webpack (mainly packaged)
const path = require('path')
const webpack = require('webpack')
const NODE_ENV = process.env.NODE_ENV
module.exports = {
entry: NODE_ENV == 'development' ? './src/main.js' : './src/lib/index.js',
output: {
path: path.resolve(__dirname, './dist'),
publicPath: '/dist/',
filename: 'build.js',
library: 'build', // library指定的就是你使用require时的模块名，这里便是require("toastPanel")
libraryTarget: 'umd', //libraryTarget会生成不同umd的代码,可以只是commonjs标准的，也可以是指amd标准的，也可以只是通过script标签引入的。
umdNamedDefine: true // 会对 UMD 的构建过程中的 AMD 模块进行命名。否则就使用匿名的 define。
},
module: {
rules: [
{
test: /\.css$/,
use: [
'vue-style-loader',
'css-loader'
],
}, {
test: /\.vue$/,
loader: 'vue-loader',
options: {
loaders: {
}
// other vue-loader options go here
}
},
{
test: /\.js$/,
loader: 'babel-loader',
exclude: /node_modules/
},
{
test: /\.(png|jpg|gif|svg)$/,
loader: 'file-loader',
options: {
name: '[name].[ext]?[hash]'
}
}
]
},
resolve: {
alias: {
'vue$': 'vue/dist/vue.esm.js'
},
extensions: ['*', '.js', '.vue', '.json']
},
devServer: {
historyApiFallback: true,
noInfo: true,
overlay: true
},
performance: {
hints: false
},
devtool: '#eval-source-map'
}
if (process.env.NODE_ENV === 'production') {
module.exports.devtool = '#source-map'
// http://vue-loader.vuejs.org/en/workflow/production.html
module.exports.plugins = (module.exports.plugins || []).concat([
new webpack.DefinePlugin({
'process.env': {
NODE_ENV: '"production"'
}
}),
new webpack.optimize.UglifyJsPlugin({
sourceMap: false,
compress: {
warnings: false
}
}),
new webpack.LoaderOptionsPlugin({
minimize: false
})
])
}
4. Create a new lib under the src folder to place the plug-in source code
①The lib file contains the index.js file (throws the required method)
import backToTop from './backToTop.vue'
const toTop = {
install: function (Vue) {
Vue.component(backToTop.name, backToTop)
}
}
// global 情况下 自动安装
if (typeof window !== 'undefined' && window.Vue) {
window.Vue.use(toTop)
}
export default toTop ②backToTop.vue (self-developed plug-in)
<template>
<div class="backToTop" :style="'z-index: ' + zIndex" @click="backToTop" v-show="bVisible">
<div class="icon"></div>
</div>
</template>
<script>
export default {
name: "back-to-top",
props: {
zIndex: {
type: Number,
default: 9999
},
triggerHeight: {
type: Number
},
smooth: {
type: Boolean,
default: true
},
scrollInterval: {
type: Number,
default: 10
},
scrollHeight: {
type: Number,
default: 100
}
},
data() {
return {
interval: null, // 计时器
bVisible: false // 按钮显示状态
};
},
methods: {
resetToTop() {
window.pageYOffset = 0;
document.documentElement.scrollTop = 0;
document.body.scrollTop = 0;
},
buttonStatus() {
var currentHeight =
window.pageYOffset ||
document.documentElement.scrollTop ||
document.body.scrollTop;
let browserHeight = this.triggerHeight || window.outerHeight / 4;
this.bVisible = currentHeight > browserHeight;
},
backToTop() {
if (this.smooth) {
var that = this,
_interval = this.scrollInterval,
_height = this.scrollHeight;
// 间隔{_interval}移动{_height}
this.interval = setInterval(function() {
that.smoothScroll(_height);
}, _interval);
} else {
this.resetToTop();
}
},
smoothScroll(y) {
if (window.pageYOffset > 0) {
window.pageYOffset = window.pageYOffset - y;
}
if (document.documentElement.scrollTop > 0) {
document.documentElement.scrollTop =
document.documentElement.scrollTop - y;
}
if (document.body.scrollTop > 0) {
document.body.scrollTop = document.body.scrollTop - y;
}
var positionNow =
window.pageYOffset ||
document.documentElement.scrollTop ||
document.body.scrollTop;
if (positionNow <= 0) {
clearInterval(this.interval);
// 清除计时器后，全部重置为零，预防回滚为负数时，不再显示的bug
this.resetToTop();
}
}
},
created() {
window.addEventListener("scroll", this.buttonStatus);
},
destroyed() {
window.removeEventListener("scroll", this.buttonStatus);
}
};
</script>
<style lang="less" scoped>
.backToTop {
position: fixed;
right: 100px;
bottom: 50px;
width: 40px;
height: 40px;
size: 40px;
border-radius: 20px;
cursor: pointer;
transition: 0.3s;

.icon {

transform: rotate(90deg); /*顺时针旋转90°*/
}
}
.backToTop:hover {
box-shadow: 0 0 20px #000;
}
</style>5. Upload the npm library
// 登录npm
npm login
// 推送插件到npm库
npm publish6. Error resolution
①The following error is reported
This is because plug-ins with the same name cannot be downloaded under the same name, just modify package.json;
②npm publish push error
Look at your npm proxy address, whether it is set to Taobao mirror, just change it back.
