码农视角 - Angular 框架起步
开发环境
1、npm
安装最新的Nodejs，便包含此工具。类似Nuget一样的东西，不过与Nuget不同的是，这玩意完全是命令行的。然后用npm来安装开发环境，也就是下边的angular cli。
2、Angular Cli
通过命令行创建项目，“编译”代码，启动调度环境等功能。angular本身使用typescript编写，需要通过ng命令，将相关的ts代码转换成js代码，以便在浏览器中运行。
安装angular cli
npm install -g @angular/cli
3、IDE
复杂的界面中，通过IDE可以大大提高开发的效率。官方推荐的IDE有：
Angular IDE by Webclipse
Built first and foremost for Angular. Turnkey setup for beginners; powerful for experts.
IntelliJ IDEA
Capable and Ergonomic Java * IDE
Visual Studio Code
VS Code is a Free, Lightweight Tool for Editing and Debugging Web Apps.
Webstorm
Lightweight yet powerful IDE, perfectly equipped for complex client-side development and server-side development with Node.js
代码结构
1、程序入口
推荐将启动代码放一个单独的文件里，比如main.ts。通过ng new 命令创建的项目文件里main.js内容如下：
import { enableProdMode } from '@angular/core';
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { AppModule } from './app/app.module';
import { environment } from './environments/environment';
if (environment.production) {
enableProdMode();
}
platformBrowserDynamic().bootstrapModule(AppModule);
一个承载脚本的HTML页面:index.html
<!doctype html> <html lang="en"> <head> <meta charset="utf-8"> <title>Test2</title> <base href="/"> <meta name="viewport" content="width=device-width, initial-scale=1"> <link rel="icon" type="image/x-icon" href="favicon.ico"> </head> <body> <app-root></app-root> </body> </html>
2、模块
模块可以认为是一个个独立的ts文件，当然要求这些文件里有export出来的类型。
3、组件
可以认为是控制器
4、模板
即视图，可以写在组件内，也可以单独的html文件。

框架结构
1、模板
2、表单
3、依赖注入
4、Http客户端
5、测试
6、路由与导航
