欢迎跟我一起学习Angular2
本文根据angular2官网手动敲码得来：

- 开发环境搭建
- 配置文件
- 安装依赖包
- *创建基础应用
- 创建组件
- 创建启动页面
- 编译启动
环境搭建
安装 Node.js and npm 。
nodejs 下载地址 https://nodejs.org/download输入 node - v 显示当前版本号
新版的NodeJS已经集成了npm，所以之前npm也一并安装好了。同样可以使用cmd命令行中键入 npm –v
配置文件
- package.json
- tsconfig.json
- typings.json
- systemjs.config.js
package.json代码块
如下：
{
"name": "angular-quickstart",
"version": "1.0.0",
"scripts": {
"start": "tsc && concurrently \"npm run tsc:w\" \"npm run lite\" ",
"lite": "lite-server",
"postinstall": "typings install",
"tsc": "tsc",
"tsc:w": "tsc -w",
"typings": "typings"

"devDependencies": {
"concurrently": "^2.2.0",
"lite-server": "^2.2.2",
"typescript": "^2.0.2",
"typings":"^1.3.2"
}
}
tsconfig.json代码块
如下：
{
"compilerOptions": {
"target": "es5",
"module": "commonjs",
"moduleResolution": "node",
"sourceMap": true,
"emitDecoratorMetadata": true,
"experimentalDecorators": true,
"removeComments": false,
"noImplicitAny": false
}
}
typings.json代码块
如下：
{
"globalDependencies": {
"core-js": "registry:dt/core-js#0.0.0+20160725163759",
"jasmine": "registry:dt/jasmine#2.2.0+20160621224255",
"node": "registry:dtde#6.0.0+20160909174046"
}
}
typings.json代码块
如下：
/**
* System configuration for Angular samples
* Adjust as necessary for your application needs.
*/
(function (global) {
System.config({
paths: {
// paths serve as alias
'npm:': 'node_modules/'
},
// map tells the System loader where to look for things
map: {
// our app is within the app folder
app: 'app',
// angular bundles
'@angular/core': 'npm:@angular/corendles/core.umd.js',
'@angular/common': 'npm:@angular/commonndles/common.umd.js',
'@angular/compiler': 'npm:@angular/compilerndles/compiler.umd.js',
'@angular/platform-browser': 'npm:@angular/platform-browserndles/platform-browser.umd.js',
'@angular/platform-browser-dynamic': 'npm:@angular/platform-browser-dynamicndles/platform-browser-dynamic.umd.js',

// other libraries
'rxjs': 'npm:rxjs',
'angular2-in-memory-web-api': 'npm:angular2-in-memory-web-api',
},
// packages tells the System loader how to load when no filename and/or no extension
packages: {
app: {
main: './main.js',
defaultExtension: 'js'
},
rxjs: {
defaultExtension: 'js'
},
'angular2-in-memory-web-api': {
main: './index.js',
defaultExtension: 'js'
}
}
});
})(this);安装依赖包
在工程目录文件下运行npm install。
中间会比较慢，等待。没有出现npm ERR!就说明安装成功。
程序会自动安装typings。
即在项目文件夹下可以看到多出来的node_modules和typings文件夹。如果typings没有自动安装，则运行 npm run typings install 手动安装。
创建基础模块
在工程目录下创建一个app文件夹，创建一个根模块suos.module.ts文件，angular2的每个应用应该有一个根模块。
Suos.module.ts内容如下：
import { NgModule } from '@angular/core';
import{BrowserModule}from'@angular/platform-browser';
@NgModule({
imports: [ BrowserModule ]
})
export class SuosModule { }创建基础组件
每个angular2应用至少由一个根组件。这里我们创建一个SuosComponent。在app目录下创建suos.component.ts 代码如下：
import { Component } from '@angular/core';
@Component({
selector: 'suosstart',
template: '<h1>Suos样例工程</h1>'
})
export class SuosComponent { }
创建启动类
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { SuosModule } from './suos.module';
const platform = platformBrowserDynamic();
platform.bootstrapModule(SuosModule);
创建启动页面
index.html
<html>
<head>
<title>Suos启动测试</title>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="stylesheet" href="style.css">
<!-- 1. Load libraries -->
<!-- Polyfill(s) for older browsers -->
<script src="node_modules/core-js/client/shim.min.js"></script>
<script src="node_modules/zone.js/dist/zone.js"></script>
<script src="node_modules/reflect-metadata/Reflect.js"></script>
<script src="node_modules/systemjs/dist/system.src.js"></script>
<!-- 2. Configure SystemJS -->
<script src="systemjs.config.js"></script>
<script>
System.import('app').catch(function(err){ console.error(err); });
</script>
</head>
<!-- 3. Display the application -->
<body>
<suosstart>加载中...</suosstart>
</body>
</html>其中style.css样式内容如下：
/* Master Styles */
h1 {
color: #369;
font-family: Arial, Helvetica, sans-serif;
font-size: 250%;
}
h2, h3 {
color: #444;
font-family: Arial, Helvetica, sans-serif;
font-weight: lighter;
}
body {
margin: 2em;
}
启动应用
npm start 会自动启动浏览器，看到出现结果页面如下即表明启动成功：
