如何在 nw.js 下获得 Angular 2 的工作“hello world”？
我使用本指南成功获得了一个可用的 Angular 2 应用程序：
https://angular.io/docs/js/latest/quickstart.html https://angular.io/docs/js/latest/quickstart.html
和一个使用这个的工作 nw.js 应用程序：
https://egghead.io/lessons/javascript-your-first-nw-js-desktop-application-in-less-than-5-分钟 https://egghead.io/lessons/javascript-your-first-nw-js-desktop-application-in-less-than-5-minutes
结合两者我得到这个：
package.json:
{
"name": "angular2-quickstart",
"version": "1.0.0",
"license": "ISC",
"dependencies": {
"angular2": "2.0.0-beta.0",
"systemjs": "0.19.6",
"es6-promise": "^3.0.2",
"es6-shim": "^0.33.3",
"reflect-metadata": "0.1.2",
"rxjs": "5.0.0-beta.0",
"zone.js": "0.5.10"
},
"description": "",
"main": "index.html",
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1"
},
"author": ""
}
index.html:
<html>
<head>
<title>Angular 2 QuickStart</title>
<!-- 1. Load libraries -->
<script src="env/lib/node_modules/angular2-quickstart/node_modules/angular2/bundles/angular2-polyfills.js"></script>
<script src="env/lib/node_modules/angular2-quickstart/node_modules/rxjs/bundles/Rx.umd.js"></script>
<script src="env/lib/node_modules/angular2-quickstart/node_modules/angular2/bundles/angular2-all.umd.js"></script>
<!-- 2. Load our 'modules' -->
<script src='app/app.component.js'></script>
<script src='app/boot.js'></script>
</head>
<!-- 3. Display the application -->
<body>
<my-app>Loading...</my-app>
</body>
</html>
app/boot.js:
(function(app) {
document.addEventListener('DOMContentLoaded', function() {
ng.platform.browser.bootstrap(app.AppComponent);
});
})(window.app || (window.app = {}));
app/app.component.js:
(function(app) {
app.AppComponent =
ng.core.Component({
selector: 'my-app',
template: '<h1>My First Angular 2 App</h1>'
})
.Class({
constructor: function() {}
});
})(window.app || (window.app = {}));
为了安装节点和依赖项，我运行了（我最终得到了节点 5.4.1；nodeenv 是https://pypi.python.org/pypi/nodeenv/0.13.6 https://pypi.python.org/pypi/nodeenv/0.13.6):
nodeenv --prebuilt env
source env/bin/activate
npm install -g nw
npm install -g
然后运行应用程序nw:
nw .
如果我用简单的纯 HTML“hello world”替换 index.html，我会在 nw 中看到该显示。但是，使用 Angular 2 index.html，我在浏览器中看到来自我的应用程序的“正在加载...”消息，并且在我启动 nw 的终端上显示了该消息：
