在 Angular 组件中包含外部 Javascript 模块

Question

我要显示this particular display diagram from GoJS(Radial Layout)

我已尝试将页面上提到的 Javascript 示例转换为 Typescript。

问题如下：

当我导入以下内容时，所谓的 RadialLayout 属性不存在：

import * as go from 'gojs';

代码中：

  $(go.RadialLayout, {... // RadialLayout does not exist for me

我在 node_modules/ 文件夹中有包，具体文件 (RadialLayout.js) 位于：

--- node_modules/
          -- gojs/
            -- extensions/
                      - RadialLayout.js

RadialLayout.js 的整个代码是 here

我尝试在 systemjs.config.js 文件中尝试添加：

map: {
            'app': 'app',
            '@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',
            'rxjs': 'npm:rxjs',
            'angular-in-memory-web-api': 'npm:angular-in-memory-web-api/bundles/in-memory-web-api.umd.js',
            '@ng-bootstrap/ng-bootstrap': 'npm:@ng-bootstrap/ng-bootstrap/bundles/ng-bootstrap.js',
            'ng2-cookies': 'npm:ng2-cookies/cookie.js',
            'gojs': 'npm:gojs/release/go.js',
    _here_-->'radiallayout': 'npm:gojs/extensions/RadialLayout.js'
        },

所以在组件文件中我可以这样：

import { RadialLayout } from 'radiallayout';

因为它可以为 gojs 或 rxjs 模块完成。但是我没有成功？

解决这个问题的方法是什么？

GoJS 的作者对如何在 TypeScript (Angular) 框架中使用他的作品没有太多想法。我在论坛上问过他

在尝试使用 Javascript 模块花了相当多的时间后，主要开发人员为 RadialLayout 共享了一个粗略的打字稿文件。论坛上的Link有个zip file.
