Angular 2 requiring html.js file for template

I'm having quite a bit of trouble with my angular2 app.

I have a very simple mvc app(I am using asp.net). enter image description here

However, I am getting a When I am trying to use a template inside my innertest component my app fails to load with the following message.

Innercomponent code`import { Component } from '@angular/core';

@Component({
    selector: 'test',
   template: require('./innerhome.component.html')
})
export class InnerTestComponent {
    name = '';
}
`

And the message is Failed to load resource: the server responded with a status of 404 (Not Found) localhost/:20 Error: (SystemJS) XHR error (404 Not Found) loading http://localhost:2802/app/components/content/innerhome.component.html.js Error: XHR error (404 Not Found) loading http://localhost:2802/app/components/content/innerhome.component.html.js at XMLHttpRequest.wrapFn [as _onreadystatechange] (http://localhost:2802/node_modules/zone.js/dist/zone.js:698:29) at ZoneDelegate.invokeTask (http://localhost:2802/node_modules/zone.js/dist/zone.js:265:35) at Zone.runTask (http://localhost:2802/node_modules/zone.js/dist/zone.js:154:47) at XMLHttpRequest.ZoneTask.invoke (http://localhost:2802/node_modules/zone.js/dist/zone.js:335:33) Error loading http://localhost:2802/app/components/content/innerhome.component.html.js as "./innerhome.component.html" from http://localhost:2802/app/components/content/innertest.component.js at XMLHttpRequest.wrapFn [as _onreadystatechange] (http://localhost:2802/node_modules/zone.js/dist/zone.js:698:29) at ZoneDelegate.invokeTask (http://localhost:2802/node_modules/zone.js/dist/zone.js:265:35) at Zone.runTask (http://localhost:2802/node_modules/zone.js/dist/zone.js:154:47) at XMLHttpRequest.ZoneTask.invoke (http://localhost:2802/node_modules/zone.js/dist/zone.js:335:33) Error loading http://localhost:2802/app/components/content/innerhome.component.html.js as "./innerhome.component.html" from http://localhost:2802/app/components/content/innertest.component.js

My systemjs.config.js file is 

(function (global) {
System.config({
    paths: {
        // псевдоним для пути к модулям
        'npm:': 'node_modules/'
    },
    // указываем загрузчику System, где искать модули
    map: {
        // наше приложение будет находиться в папке app
        app: 'app',
        // пакеты angular
        '@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/router': 'npm:@angular/router/bundles/router.umd.js',
        '@angular/forms': 'npm:@angular/forms/bundles/forms.umd.js',
        '@angular/upgrade': 'npm:@angular/upgrade/bundles/upgrade.umd.js',
        // остальные пакеты
        'rxjs': 'npm:rxjs',
        'angular-in-memory-web-api': 'npm:angular-in-memory-web-api/bundles/in-memory-web-api.umd.js'
    },
    // пакеты, которые указывают загрузчику System, как загружать файлы без имени и расширения
    packages: {
        app: {
            main: './main.js',
            defaultExtension: 'js'
        },
        rxjs: {
            defaultExtension: 'js'
        }
    }
});

})(this);

I do not understand the cause of this issue.

Please advise.

Solution

  • In the decorator, you should use templateUrl instead of template. As long as the file you are referring to is in the same folder, you should only use filename, not path:

    templateUrl: 'innerhome.component.html'

    Every time you point to another file in the component decorator, you also need to include:

    moduleId: module.id,

    And make sure you have InnerTestComponent in your app.module declarations.

    The entire component would then look like this:

    import { Component } from '@angular/core';

    @Component({
  moduleId: module.id,
  selector: 'test',
  templateUrl: 'innerhome.component.html'
})
export class InnerTestComponent {
  name = '';
}
