Angular cli构建项目

一，准备阶段。

初始化项目，并尝试运行：

ng new myProject

cd myProject

ng serve

二，添加外部框架：

npm i jquery --save

由于typescript不能直接识别js，需要引入类型描述文件

npm i @types/jquery --save

文件会下载到node_modules文件夹

然后在package.json文件里添加进来：

手动在angular.json文件里，添加对js文件及css文件的引用：

三，新建组件

将需求内容分割成若干组件，然后新建这些组件。

使用命令

$ ng g component product

app文件夹内生成了相关组件文件夹，且app.module.ts内会自动引入新增组件

四，编写主组件

五，bootstrap相关代码
