【webpack】webpack配置

我自己能看懂。

1.    安装npm
2.    Npm install –g webpack
3.    创建项目
4.    Npm init
5.    创建webpack.config.js，并配置
6.    安装项目webpack:npm install webpack –save-dev
7.    安装插件等：npm install babel-loader babel-core babel-preset-react babel-preset-es2015 --save-dev
8.    编译:webpack

文档传送门：https://doc.webpack-china.org/configuration/#-

webpack.config.js内如如下：

var path = require("path");
var webpack =require("webpack");
var fs=require("fs");
var glob=require("glob");


//取文件后缀名
function GetFileExt(filepath) {
    if (filepath) {
        if(filepath.indexOf("/")>0){
           return filepath.substring(filepath.lastIndexOf("/")+1);
        }else{
           return filepath;
        }
    }
}
//取文件名不带后缀
function GetFileNameNoExt(filepath) {
    var fp= GetFileExt(filepath);
    return fp.substring(0,fp.lastIndexOf("."));
}

//获取一个初始化的webpack设置
function GetSetting(){
    return {
        entry: { 
        },//入口
        output: {//出口
            path: __dirname + "/build/",
