我想写一个没有ES6 /打字稿的角度2应用程序,但是使用模块系统,例如SystemJS。
我写了这个应用程序(GitHub Project)并通过加载来纠正错误。 现在应用程序启动成功,我的代码似乎没有运行。我看到空站点。 这是我的SystemJS配置:
SystemJS.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
'my-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',
'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: './app/main.js',
defaultExtension: 'js'
},
rxjs: {
defaultExtension: 'js'
},
'angular2-in-memory-web-api': {
main: './index.js',
defaultExtension: 'js'
}
}
});
/src/app/app.component.js中的我的组件
var ngCore = require('@angular/core');
function MyAppComponent(){
}
MyAppComponent.annotations = [
ngCore.Component({
selector: 'my-app',
template: '<h1>Hello Angular</h1>'
})
];
module.exports = MyAppComponent;
我的模块在/src/app/app.module.js
var ngCore = require('@angular/core');
var platformBrowser = require('@angular/platform-browser');
var AppComponent = require('my-app/app/app.component.js');
function MyAppModule(){
}
MyAppModule.annotations = [
ngCore.NgModule({
imports: [ platformBrowser.BrowserModule ],
declarations: [ AppComponent ],
bootstrap: [ AppComponent ]
})
];
module.exports = MyAppModule;
var platformBrowserDynamic = require('@angular/platform-browser-dynamic');
var AppModule = require('my-app/app/app.module.js');
document.addEventListener('DOMContentLoaded', function() {
platformBrowserDynamic
.platformBrowserDynamic()
.bootstrapModule(AppModule);
});
我没有看到任何错误,但我也没有看到我的组件。
我做错了什么?
答案 0 :(得分:1)
我明白。谢谢你的帮助。我删除了&#34; document.addEventListener&#34;。我的main.js:
var platformBrowserDynamic = require('@angular/platform-browser-dynamic');
var AppModule = require('my-app/app/app.module.js');
platformBrowserDynamic
.platformBrowserDynamic()
.bootstrapModule(AppModule);
我遇到了元数据错误,因为我使用了过时的格式。现在我的Component.js是
var ngCore = require('@angular/core');
MyAppComponent = ngCore.Component({
selector: 'my-app',
template: '<h1>Hello Angular</h1>'
}).Class({
constructor: function(){
}
});
module.exports = MyAppComponent;
我的Module.js如此:
var ngCore = require('@angular/core');
var platformBrowser = require('@angular/platform-browser');
var AppComponent = require('my-app/app/app.component.js');
MyAppModule = ngCore.NgModule({
imports: [ platformBrowser.BrowserModule ],
declarations: [ AppComponent ],
bootstrap: [ AppComponent ]
}).Class({
constructor: function (){
}
});
module.exports = MyAppModule;
