webpack配置方法小结

大家都知道webpack如何配置吗？本文主要和大家分享webpack实用配置方法总，也给大家做个参考，希望能帮助到大家。

1、webpack.config.js配置文件为：

//处理共用、通用的js
var webpack = require('webpack');
//处理html模板
var htmlWebpackPlugin = require('html-webpack-plugin');
//css单独打包
var ExtractTextPlugin = require("extract-text-webpack-plugin");

// 获取html-webpack-plugin参数的方法 
var getHtmlConfig = function(name, title) {
  return {
    //本地模板文件的位置
    template: './src/view/' + name + '.html',
    //输出文件的目录和文件名称
    filename: 'view/' + name + '.html',
    //添加特定favicon路径到输出的html文档中
    favicon: './favicon.ico',
    //生成的html文档的标题
    title: title,
    //向template或者templateContent中注入所有静态资源，不同的配置值注入的位置不经相同。true或者body：所有JavaScript资源插入到body元素的底部
    inject: true,
    //是否为所有注入的静态资源添加webpack每次编译产生的唯一hash值
    hash: true,
    //允许插入到模板中的一些chunk，不配置此项默认会将entry中所有的thunk注入到模板中。在配置多个页面时，每个页面注入的thunk应该是不相同的，需要通过该配置为不同页面注入不同的thunk；
    chunks: ['common', name]
  };
};

var config = {
  //多页面配置
  entry: {
    //通用模块
    'common': ['./src/page/common/index.js'],
    //登录模块
    'login': ['./src/page/login/index.js'],
    //首页
    'index': ['./src/page/index/index.js']
  },
  output: {
    //打包后文件存放的地方
    path: __dirname + '/dist',
    //打包后的文件名
    filename: 'js/[name].js'
  },
  //将外部变量或者模块加载进来，并且不将外部变量或者模块编译进文件中
  externals: {
    'jquery': 'window.jQuery'
  },
  module: {
    loaders: [
      //编译ES6
      {
        test: /\.js$/,
        //以下目录不处理
        exclude: /node_modules/,
        //处理以下目录
        include: /src/,
        loader: "babel-loader?cacheDirectory",
        //配置的目标运行环境自动启用需要的 babel 插件
        query: {
          presets: ['latest']
        }
      },
      //处理css
      {
        test: /\.css$/,
        //css单独打包
        use: ExtractTextPlugin.extract({
          fallback: "style-loader",
          use: [{
              loader: 'css-loader',
              options: {
                //支持@important引入css
                importLoaders: 1
              }
            },
            {
              loader: 'postcss-loader',
              options: {
                plugins: function() {
                  return [
                    //一定要写在require("autoprefixer")前面，否则require("autoprefixer")无效
                    require('postcss-import')(),
                    require("autoprefixer")({
                      "browsers": ["Android >= 4.1", "iOS >= 7.0", "ie >= 8"]
                    })
                  ]
                }
              }
            }
          ]
        })
      },
      //处理less（同理sass）
      {
        test: /\.less$/,
        //css单独打包
        use: ExtractTextPlugin.extract({
          fallback: "style-loader",
          use: [{
              loader: 'css-loader',
              options: {
                //支持@important引入css
                importLoaders: 1
              }
            },
            {
              loader: 'postcss-loader',
              options: {
                plugins: function() {
                  return [
                    //一定要写在require("autoprefixer")前面，否则require("autoprefixer")无效
                    require('postcss-import')(),
                    require("autoprefixer")({
                      "browsers": ["Android >= 4.1", "iOS >= 7.0", "ie >= 8"]
                    })
                  ]
                }
              }
            },
            'less-loader'
          ]
        })
      },
      //处理图片
      {
        test: /\.(gif|png|jpg|woff|svg|eot|ttf)\??.*$/i,
        loaders: [
          //小于8k的图片编译为base64，大于10k的图片使用file-loader      
          'url-loader?limit=8192&name=img/[name]-[hash:5].[ext]',
          //图片压缩
          'image-webpack-loader'
        ]

      }
    ]
  },
  plugins: [
    //html模板处理
    new htmlWebpackPlugin(getHtmlConfig('index', '首页')),
    new htmlWebpackPlugin(getHtmlConfig('login', '登录页')),
    //通用模块编译到js/common.js
    new webpack.optimize.CommonsChunkPlugin({
      //公共块的块名称
      name: 'common',
      //生成的文件名
      filename: 'js/common.js'
    }),
    //css单独打
    new ExtractTextPlugin('css/[name].css')
  ]
}
module.exports = config;
