模仿element发布一个npm关于vue插件的包

1、初始化一个vue项目/vue init webpack ，可以把多余的文件删除。只保留下面

2、修改package.json

{
  "name": "ggg-ui",
  "description": "A Vue.js project",
  "version": "1.1.1",
  "author": "guowf <[email protected]>",
  "license": "MIT",
  "private": false,
  "scripts": {
    "dev": "cross-env NODE_ENV=development webpack-dev-server --open --hot",
    "build": "webpack --display-error-details --config webpack.config.js"
  },
  "dependencies": {
    "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",
    "vue-loader": "^13.0.5",
    "vue-template-compiler": "^2.4.4",
    "webpack": "^3.6.0",
    "webpack-dev-server": "^2.9.1"
  },
  "main": "/dist/gggUi.js",
  "repository": {
    "type": "git",
    "url": "https://github.com/13714273163/ggg-vue-ui.git"
  }
}

　3、根目录新建webpack.config.js文件内容如下

var path = require('path')
var webpack = require('webpack')

module.exports = {
  entry: './src/index.js',
  output: {
    path: path.resolve(__dirname, './dist'),
    publicPath: '/dist/',
    filename: 'gggUi.js', // 我们可不想打包后叫build.js 多low啊 起一个与项目相对应的
    library: 'gggUi', // library指定的就是你使用require时的模块名，这里便是require("PayKeyboard")
    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: true,
      compress: {
        warnings: false
      }
    }),
    new webpack.LoaderOptionsPlugin({
      minimize: true
    })
  ])
}

4、修改.gitignore文件

切记要把dist加上注释，不然没把dist传上去

5、我的src文件参考

其中index.js是总的文件出口，pachages下面的index是各个文件的出口（也就是element可以一次性导入或者按需导入的做法）

5、打包：npm run build /发布：npm publish 

6、在新项目引用试试

main.js

xx.vue

效果图
