这里有新鲜出炉的AngularJS开发指南，程序狗速度看过来！
AngularJS 前端JS框架
AngularJS诞生于Google是一款优秀的前端JS框架，已经被用于Google的多款产品当中。AngularJS有着诸多特性，最为核心的是：MVC、模块化、自动化双向数据绑定、语义化标签、依赖注入，等等。
1.创建package.json文件
cd xhhAngular
npm init
package.json:
{
"name": "xhhangular",
"version": "1.0.0",
"description": "",
"scripts": {
"start": "webpack-dev-server --inline --hot --colors --progress",
"postinstall": "./node_modules/.bin/typings install"
},
"author": "xhh",
"license": "ISC",
"dependencies": {
"@angular/common": "~2.1.0",
"@angular/compiler": "~2.1.0",
"@angular/core": "~2.1.0",
"@angular/forms": "~2.1.0",
"@angular/http": "~2.1.0",
"@angular/platform-browser": "~2.1.0",
"@angular/platform-browser-dynamic": "~2.1.0",
"@angular/router": "~3.1.0",
"@angular/upgrade": "~2.1.0",
"angular-in-memory-web-api": "~0.1.5",
"bootstrap": "^3.3.7",
"core-js": "^2.4.1",
"reflect-metadata": "^0.1.8",
"rxjs": "5.0.0-beta.12",
"zone.js": "^0.6.25"
},
"devDependencies": {
"html-webpack-plugin": "^2.28.0",
"path": "^0.12.7",
"ts-loader": "^0.8.2",
"typescript": "^2.0.3",
"typings": "^1.4.0",
"webpack": "^1.13.2",
"webpack-dev-server": "^1.16.1"
}
}
2.创建tsconfig.json
{
"compilerOptions": {
"target": "es5",
"module": "commonjs",
"moduleResolution": "node",
"sourceMap": true,
"emitDecoratorMetadata": true,
"experimentalDecorators": true,
"removeComments": true,
"noImplicitAny": true,
"declaration": false
}
}
3.创建typings.json
{
"globalDependencies": {
"es6-shim": "registry:dt/es6-shim#0.31.2+20160602141504"
}
}
现在运行 npm install 安装 package.json 里所有的依赖包：
npm install --registry=https://registry.npm.taobao.org/
4.创建app.module.ts
import 'zone.js/dist/zone';
import 'reflect-metadata';
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import {AppComponent} from './app.component';
// components, directives and pipes — belong in the declarations array.
@NgModule({
imports: [ BrowserModule ],
declarations: [ AppComponent ],
bootstrap: [ AppComponent ]
})
export class AppModule { }
5.创建app.component.ts
import { Component } from '@angular/core';
// 为 AppComponent 组件类添加注解
@Component({
selector: 'my-app',
template: '<h1>Hello {{title}}</h1><input type="text" #userRef (keyup)="onKeyup1(userRef.value)">',
styles:['h1{color:red}']
})
export class AppComponent {
title='World';
onKeyup1(userInput:string){
//这是typescript的写法，定义你的参数为string类型，并在调用的时候做检查
this.title=userInput;
}
}
6.创建main.ts
// 引入启动器
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
// 引入入口文件
import { AppModule } from './app.module';
// 启动应用
const platform = platformBrowserDynamic();
platform.bootstrapModule(AppModule);
7.创建主页面index.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<title>Angular2 QuickStart</title>
</head>
<body>
<!-- 对应 @Component({ selector: 'my-app', ... }) -->
<my-app></my-app>
<!-- 编译打包后的文件 -->
<script src="dist/bundle.js"></script>
</body>
</html>
8.创建webpack.config.js
var path = require('path');
var webpack = require('webpack');
module.exports = {
entry: {
main: './src/main.ts'
},
output: {
path: path.resolve(__dirname, 'dist'),
publicPath: '/dist/',
filename: 'bundle.js'
},
devtool: 'cheap-module-eval-source-map',
module: {
loaders: [
{
test: /\.ts$/,
loader: 'ts'
}
]
},
// require 文件时可省略后缀 .js 和 .ts
resolve: {
extensions: ['', '.js', '.ts']
},
// 配置 webpack-dev-server
devServer:{
historyApiFallback: true,
hot: true,
inline: true,
port: 3000 // 修改端口，一般默认是8080
},
plugins: [
new webpack.optimize.UglifyJsPlugin({minimize: true})
]
};
然后运行项目： npm start
访问localhost:3000即可。
