Aurelia app "Hello World" not working at all

Question

I am creating a Sharepoint framework webpart, and I am trying to use Aurelia as my JavaScript framework.

Basically I created a Sharepoint framework webpart, which when created with Yeoman, creates this folder structure.

Then my files (just a simple hello world):

app.html

<template>
  ${message}
</template>

app.js

export class App {
  message = 'hello world';
}

main.ts

import {Aurelia} from 'aurelia-framework';

export function configure(aurelia) {
  aurelia.use
    .standardConfiguration()
    .developmentLogging();

  aurelia.start().then(a => a.setRoot());
}

index.html

 <div aurelia-app>
    <h1>Loading...</h1>
    <h2> ftw </h2>
    <script src="jspm_packages/system.js"></script>
    <script src="config.js"></script>
    <script>
      System.import('aurelia-bootstrapper');
    </script>

  </div>

And the helloworld webpart:

import {
  BaseClientSideWebPart,
  IPropertyPaneSettings,
  IWebPartContext,
  PropertyPaneTextField
} from '@microsoft/sp-client-preview';

import styles from './HelloWorld.module.scss';
import * as strings from 'helloWorldStrings';
import { IHelloWorldWebPartProps } from './IHelloWorldWebPartProps';
import { configure } from './main';
import * as systemjs from 'systemjs';
import {Aurelia} from 'aurelia-framework';

export default class HelloWorldWebPart extends BaseClientSideWebPart<IHelloWorldWebPartProps> {

  public constructor(context: IWebPartContext) {
    super(context);
  }

  public render(): void {
    if (this.renderedOnce === false) {
      this.domElement.innerHTML = require('./index.html');
    }
  }

  protected get propertyPaneSettings(): IPropertyPaneSettings {
    return {
      pages: [
        {
          header: {
            description: strings.PropertyPaneDescription
          },
          groups: [
            {
              groupName: strings.BasicGroupName,
              groupFields: [
                PropertyPaneTextField('description', {
                  label: strings.DescriptionFieldLabel
                })
              ]
            }
          ]
        }
      ]
    };
  }
}

The code renders the HTML in the page, but without the message.

I don't see any error in the browser console.

I installed Aurelia with NPM no jspm. Executing gulp serve does not show any compilation error.

I also created a typings file "aurelia.d.ts" in the typings subfolder.

I think that my main problem is in the index.html, as it has a reference to 2 JavaScript files, but I am not sure how to reference them because they are inside the NPM modules folder and I don't think they are deployed when doing gulp serve.

And by the way, here's my config.json:

{
  "entries": [
    {
      "entry": "./lib/webparts/helloWorld/HelloWorldWebPart.js",
      "manifest": "./src/webparts/helloWorld/HelloWorldWebPart.manifest.json",
      "outputPath": "./dist/hello-world.bundle.js"
    }
  ],
  "externals": {
    "@microsoft/sp-client-base": "node_modules/@microsoft/sp-client-base/dist/sp-client-base.js",
    "@microsoft/sp-client-preview": "node_modules/@microsoft/sp-client-preview/dist/sp-client-preview.js",
    "@microsoft/sp-lodash-subset": "node_modules/@microsoft/sp-lodash-subset/dist/sp-lodash-subset.js",
    "office-ui-fabric-react": "node_modules/office-ui-fabric-react/dist/office-ui-fabric-react.js",
    "react": "node_modules/react/dist/react.min.js",
    "react-dom": "node_modules/react-dom/dist/react-dom.min.js",
    "aurelia": "node_modules/aurelia-framework/dist/aurelia-framework.js",
    "systemjs" : "node_modules/systemjs/dist/systemjs/system.js"
  },
  "localizedResources": {
    "helloWorldStrings": "webparts/helloWorld/loc/{locale}.js"
  }
}

Errors in the console:

Answer 1

Without specifying an attribute to the aurelia-app, it loads by default app.html and app.js. So what you'd want to do is change it to:

<div aurelia-app="main">

So that loads main.js and actually starts aurelia.

Here's a link to the documentation about bootstrapping aurelia.
