俊先 人气:0前言
之前已经给大家介绍了Angular2开发环境搭建教程之VS Code,本文将详细介绍利用VS Code如何开发AngularJS2应用程序的相关内容,分享出来供大家参考学习,下面话不多说了,来一起看看详细的介绍吧。
运行环境:
1、Windows 10
2、Node 6.7.0
3、npm 3.10.8
4、TypeScript 2.0.3
创建项目
1、创建文件夹:angular2-quickstart,启动VS Code,打开刚创建的文件夹:angular2-quickstart。
2、在根文件夹(angular2-quickstart)下,创建package.json文件:
{ "name": "angular-quickstart", "version": "1.0.0", "scripts": { "start": "tsc && concurrently \"tsc -w\" \"lite-server\" ", "lite": "lite-server", "postinstall": "typings install", "tsc": "tsc", "tsc:w": "tsc -w", "typings": "typings" }, "license": "ISC", "dependencies": { "@angular/common": "~2.0.2", "@angular/compiler": "~2.0.2", "@angular/core": "~2.0.2", "@angular/forms": "~2.0.2", "@angular/http": "~2.0.2", "@angular/platform-browser": "~2.0.2", "@angular/platform-browser-dynamic": "~2.0.2", "@angular/router": "~3.0.2", "@angular/upgrade": "~2.0.2", "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", "systemjs": "0.19.39", "zone.js": "^0.6.25" }, "devDependencies": { "concurrently": "^3.1.0", "lite-server": "^2.2.2", "typescript": "^2.0.3", "typings": "^1.4.0" } }
3、在根文件夹(angular2-quickstart)下,创建tsconfig.json文件:
{ "compilerOptions": { "target": "es5", "module": "commonjs", "moduleResolution": "node", "sourceMap": true, "emitDecoratorMetadata": true, "experimentalDecorators": true, "removeComments": false, "noImplicitAny": false } }
4、在根文件夹(angular2-quickstart)下,创建typings.json文件:
{ "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" } }
5、在根文件夹(angular2-quickstart)下,创建systemjs.config.js(JavaScript脚本)文件:
/** * 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);
文件结构:
|_ angular2-quickstart |_ app | |_ app.component.ts | |_ main.ts |_ node_modules ... |_ typings ... |_ index.html |_ package.json |_ tsconfig.json |_ typings.json
安装依赖包(最关键一步)
使用 npm 命令来安装 package.json 中列出的依赖包。在命令行 cmd 窗口,输入:cd angular2-quickstart,进入angular2-quickstar文件夹下,输入下列命令:
npm install
创建TypeScript应用程序
1、在VS Code中,在根文件夹(angular2-quickstart)下,创建app子文件夹。
2、在子app文件夹下,创建TypeScript文件app.module.ts:
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、在子app文件夹下,创建TypeScript文件app.component.ts:
import { Component } from '@angular/core'; @Component({ selector: 'my-app', template: '<h1>我的第一个 AngularJS 2 应用程序</h1>' }) export class AppComponent { }
4、在子app文件夹下,创建TypeScript文件main.ts:
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic'; import { AppModule } from './app.module'; const platform = platformBrowserDynamic(); platform.bootstrapModule(AppModule);
5、在根文件夹(angular2-quickstart)下,创建html文件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.jshttps://img.qb5200.com/download-x/dist/zone.js"></script> <script src="node_modules/reflect-metadata/Reflect.js"></script> <script src="node_modules/systemjshttps://img.qb5200.com/download-x/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>
6、在根文件夹(angular2-quickstart)下,创建css文件styles.css:
/* 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; }
配置应用程序
1、在VS Code中,在根文件夹(angular2-quickstart)下,创建.vscode子文件夹。
2、在.vscode子文件夹下,创建settings.json文件:
// 将设置放入此文件中以覆盖默认值和用户设置。 { "typescript.tsdk": "node_modules/typescript/lib", // ts 项目, 隐藏 .js 和 .js.map 文件 "files.exclude": { "node_modules": true, "**/*.js": { "when": "$(basename).ts" }, "**/*.js.map": true } }
3、在.vscode子文件夹下,创建tasks.json文件:
{ // See https://go.microsoft.com/fwlink/?LinkId=733558 // for the documentation about the tasks.json format "version": "0.1.0", "command": "cmd", "isShellCommand": true, "showOutput": "always", "args": ["/C npm start"] }
运行应用程序至此,配置完毕,按 Ctrl + Shift + B 编译,程序将会将Typescript编译成 Javascript ,同时启动一个 lite-server, 加载我们编写的index.html。 显示:我的第一个 Angular 2 应用程序
