zone.js:344 Unhandled Promise rejection: Failed to load app.template.html in angular2

UPDATE

According to Angular 2 Docs change-log

All mention of moduleId removed. "Component relative paths" cookbook deleted (2017-03-13)

We added a new SystemJS plugin (systemjs-angular-loader.js) to our recommended SystemJS configuration. This plugin dynamically converts "component-relative" paths in templateUrl and styleUrls to "absolute paths" for you.

We strongly encourage you to only write component-relative paths. That is the only form of URL discussed in these docs. You no longer need to write @Component({ moduleId: module.id }), nor should you.

angular quickstart

meta: {
  './*.js': {
    loader: 'systemjs-angular-loader.js'
  }
}

angular-cli

changelog 1.0.0-rc.4 (2017-03-20)

To align with @angular/core behavior, all templateUrl and styleUrls are now treated as relative - developers should use the ./foo.html form in all cases.

PREVIOUS VERSION

By default, you should specify the full path back to the application root. It is absolute with respect to the application root.

For your case it may be:

@Component({
  selector: 'cwf',
  templateUrl: 'app/app.template.html' // or src
})
export class AppComponent {}

If you want to specify template and style URLs relative to their component class files you should set moduleId property to decorator of your component:

@Component({
  moduleId: module.id
  selector: 'cwf',
  templateUrl: './app.template.html'
})
export class AppComponent {}

If you use SystemJS, then it should be __moduleName variable instead of the module.id variable:

@Component({
  moduleId: __moduleName,
  selector: 'cwf',
  templateUrl: './app.template.html'
})
export class AppComponent {}

worked for me like this, if you defined in inner folders

@Component({

    selector: 'people-list', 
    templateUrl:'app/component/peopleList/people-list.html'
})
