javascript - Aurelia 应用程序 "Hello World"根本不工作

Question

我正在创建一个 Sharepoint 框架 Web 部件，并且我正在尝试使用 Aurelia 作为我的 JavaScript 框架。

基本上，我创建了一个 Sharepoint 框架 Web 部件，当使用 Yeoman 创建时，它创建了这个 folder structure。

然后是我的文件(只是一个简单的 hello world):

应用.html

<template>
  ${message}
</template>

应用程序.js

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

主要.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>

还有 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
                })
              ]
            }
          ]
        }
      ]
    };
  }
}

代码在页面中呈现 HTML，但没有消息。

我在浏览器控制台中没有看到任何错误。

我用 NPM 没有 jspm 安装了 Aurelia。执行 gulp serve 没有显示任何编译错误。

我还在 typings 子文件夹中创建了一个 typings 文件“aurelia.d.ts”。

我认为我的主要问题出在 index.html 中，因为它引用了 2 个 JavaScript 文件，但我不确定如何引用它们，因为它们位于 NPM 模块文件夹中，我认为它们不存在在执行 gulp serve 时部署。

顺便说一下，这是我的 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-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",

    "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"
  }
}

控制台错误:

Answer 1

无需为 aurelia-app 指定属性，它会默认加载 app.html 和 app.js。因此，您要做的是将其更改为:

<div aurelia-app="main">

因此加载 main.js 并实际启动 aurelia。

Here's a link to the documentation关于引导 aurelia。
