一.安装坏境:node.js和npm;
node.js在5.x.x或以上，npm在3.x.x或以上。
node -v 和npm -v检查安装版本。

创建一个文件：
mkdir angular-quickstart
cd angular-quickstart
二.装一些配置文件：
package.json
用来标记出本项目所需的 npm 依赖包。
package.json
{
"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"
},
"license": "ISC",
"dependencies": {
"@angular/common": "2.0.0",
"@angular/compiler": "2.0.0",
"@angular/core": "2.0.0",
"@angular/forms": "2.0.0",
"@angular/http": "2.0.0",
"@angular/platform-browser": "2.0.0",
"@angular/platform-browser-dynamic": "2.0.0",
"@angular/router": "3.0.0",
"@angular/upgrade": "2.0.0",
"core-js": "^2.4.1",
"reflect-metadata": "^0.1.3",
"rxjs": "5.0.0-beta.12",
"systemjs": "0.19.27",
"zone.js": "^0.6.23",
"angular2-in-memory-web-api": "0.0.20",
"bootstrap": "^3.3.6"
},
"devDependencies": {
"concurrently": "^2.2.0",
"lite-server": "^2.2.2",
"typescript": "^2.0.2",
"typings":"^1.3.2"
}
}
tsconfig.json
定义了 TypeScript 编译器如何从项目源文件生成 JavaScript 代码。
tsconfig.json
{
"compilerOptions": {
"target": "es5",
"module": "commonjs",
"moduleResolution": "node",
"sourceMap": true,
"emitDecoratorMetadata": true,
"experimentalDecorators": true,
"removeComments": false,
"noImplicitAny": false
}
}
typings.json
为那些 TypeScript 编译器无法识别的库提供了额外的定义文件。
typings.json
{
"globalDependencies": {
"core-js": "registry:dt/core-js#0.0.0+20160725163759",
"jasmine": "registry:dt/jasmine#2.2.0+20160621224255",
"node": "registry:dt/node#6.0.0+20160909174046"
}
}
systemjs.config.js
为模块加载器提供了该到哪里查找应用模块的信息，并注册了所有必备的依赖包。 它还包括文档中后面的例子需要用到的包。
systemjs.config.js
/**
* 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/core/bundles/core.umd.js',
'@angular/common': 'npm:@angular/common/bundles/common.umd.js',
'@angular/compiler': 'npm:@angular/compiler/bundles/compiler.umd.js',
'@angular/platform-browser': 'npm:@angular/platform-browser/bundles/platform-browser.umd.js',
'@angular/platform-browser-dynamic': 'npm:@angular/platform-browser-dynamic/bundles/platform-browser-dynamic.umd.js',
'@angular/http': 'npm:@angular/http/bundles/http.umd.js',
'@angular/router': 'npm:@angular/router/bundles/router.umd.js',
'@angular/forms': 'npm:@angular/forms/bundles/forms.umd.js',
// other libraries
'rxjs': 'npm:rxjs',
'angular-in-memory-web-api': 'npm:angular-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'
},
'angular-in-memory-web-api': {
main: './index.js',
defaultExtension: 'js'
}
}
});
})(this);
三.npm install
创建完文件后面再angular-quickstart目录下npm install；
如果在运行 npm install之后没有出现 typings目录，你就需要通过命令手动安装它：
npm run typings install
四.<font face="微软雅黑">mkdir app</font>创建app文件
（1）文件内创建跟模块app/app.module.ts
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
@NgModule({
imports: [ BrowserModule ]
})
export class AppModule { }
（2）根组件app/app.component.ts
import { Component } from '@angular/core';@Component({ selector: 'my-app', template: '
My First Angular App
'})
export class AppComponent { }
再次编辑app/app.module.ts文件
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { AppComponent } from './app.component';
@NgModule({
imports: [ BrowserModule ],
declarations: [ AppComponent ],
bootstrap: [ AppComponent ]
})
export class AppModule { }
（3）需要main.ts文件加载根组件
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { AppModule } from './app.module';
const platform = platformBrowserDynamic();
platform.bootstrapModule(AppModule);
五.在外边的根目录创建index.html
<html>
<head>
<title>Angular QuickStart</title>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="stylesheet" href="styles.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>
<my-app>Loading...</my-app>
</body>
</html>
创建一个style.css文件
/* 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;
}
