打包项目-错误信息

运行时注意
1.runtime-only ->代码中,不可以有任何的template
2.runtime-compiler ->代码中,可以有template,因为有compiler可以用于编译template

webpack.config.js中新增

  resolve: {
    
    
    // alias: 别名
    extensions: ['.js', '.css', '.vue'],
    alias: {
    
    
      'vue$': 'vue/dist/vue.esm.js'
    }
  }

el和template区别

为了能够识别vue文件，先进行安装

npm install vue-loader vue-template-compiler --save-dev

然后进行配置文件webpack.config.js

      {
    
    
        test: /\.vue$/,
        use: ['vue-loader']
      }

出错试试改下版本

然后执行命令npm install

plugin

  plugins: [
      new webpack.BannerPlugin('最终版权归aaa所有'),
      new HtmlWebpackPlugin({
    
    
        template: 'index.html'
      }),
      new UglifyjsWebpackPlugin()
  ]

打包html的plugin

对应文件下执行
npm install html-webpack-plugin --save-dev

F:\IdeaProjects\LearnVuejs04-v2\01-webpack的使用\05-webpack的Plugin>npm install html-webpack-plugin --save-dev

修改webpack.config.js中的
新增

const HtmlWebpackPlugin = require('html-webpack-plugin')

js压缩的Plugin

对应文件下执行
npm install [email protected] --save-dev

搭建本地服务器

先进行安装

npm install --save-dev [email protected]

然后进行配置文件webpack.config.js

  devServer: {
    
    
    contentBase: './dist',
    inline: true
  }

package.json添加

    "dev": "webpack-dev-server --open"

运行命令npm run dev
