webpack实用配置总结

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'],

        filename: 'js/[name].js'
    },
