yeoman-generator
yeoman-generator是一个构建脚手架的工具，如果你还不了解你自行google到官网看下，这里只简单介绍一下，它是一个脚手架生成工具，比如在之前写 ASP.NET MVC 的时候，Visual Studio 会给你选模板，然后生成一个项目的基本结构（脚手架），这对提升开发体验是很有帮助的，节省了重复劳动。然而前端没有什么 IDE（WebStorm？或许吧），没有一个固定的开发模式，可能你喜欢 jshint，我想用 eslint，你觉得 angular 顺手，我觉得 vue 更合适，这时就可以使用 Yeoman 这个工具，生成一个适合自己技术栈的脚手架，需要的一些文件都预先生成好，给自己省点事
yeoman-generator的开发配置
环境准备
安装或者更新一下你的node和npm
npm install -g n //首先安装n模块
n stable //升级node.js到最新稳定版
n 5.0.0 //或者指定版本升级
node -v //检查更新是否成功
然后安装yeoman
npm install -g yo
创建目录
新建一个名为generator-xxx（yeoman脚手架命名规范）的文件夹，我这里叫generator-vue-webpack。然后在目录下执行npm init创建package.json文件。修改为
{
"name":"generator-vue-webpack",
"version":"1.0.0",
"description":"vue2+webpack2脚手架",
"main":"generators/index.js",
"scripts": {
"test":"echo \"Error: no test specified\" && exit 1"
},
"files": [
"generators"
],
"repository": {
"type":"git",
"url":"git+https://github.com/xiaoxinghug/generator-vuepackage.git"
},
"keywords": [
"yeoman-generator"
],
"dependencies": {
"deep-extend":"^0.4.1",
"generator-license":"^3.1.1",
"yeoman-generator":"^0.22.0",
"chalk":"^1.1.3",
"yosay":"^1.2.1",
"lodash":"^4.11.1",
"mkdirp":"^0.5.1"
},
"author":"chenxiaoxing",
"license":"ISC",
"bugs": {
"url":"https://github.com/xiaoxinghug/generator-vuepackage/issues"
},
"homepage":"https://github.com/xiaoxinghug/generator-vuepackage#readme",
"license":"Apache-2.0"
}
然后在此目录下新建generators->app->index.js，generators-app-templates，如下图所示：
。
generator-reactpackage是整个npm包的项目文件夹
templates目录里面就是我们最后要用到的项目模版文件，里面的内容是一个完整的前端项目，可以自定义。
index.js是开发脚手架的主要逻辑文件。
开始开发
然后编辑index.js文件：

yeoman-generator的使用
> npm install -g yo
> npm install -g generator的包名。使用yeoman-generator的脚手架包名需要以 generator-取名字，比如说你发布的npm包名是generator-angular就可以直接
> yo angular
