const path = require('path');

module.exports = {
  entry: './src/index.js',
  output: {
    filename: 'bundle.js',
    path: path.resolve(__dirname, 'dist')
  },
  module: {

      rules:[
              //   css加载
    //包下载命令：npm install --save-dev style-loader css-loader
          {
          test:/.css$/,
          use:[
              'style-loader',
              'css-loader',
          ]
      },
          //   图片加载及字体加载
    //包下载命令：npm install --save-dev file-loader
      {
          test:/.(png|jpg|gif)$/,

          ]
      },
    //   数据加载 (json是内置的，所以无需下载对应的包)
    //包命令：npm install --save-dev csv-loader xml-loader
