How to define Excel using microsoft office-js in Angular 6

问题

I am following this site to integrate office js

On declaring like this:

import * as Excel from '@microsoft/office-js/excel' It's showing compile time error:

Cannot find module '@microsoft/office-js/excel'

On declaring like this:

declare var Excel: any

It's showing run time error:

ERROR ReferenceError: Excel is not defined

Please suggest how to declare it. I need to use it like this:

Excel.run(session, (context){
   ...
});

Install office type definition:

npm install --save @types/office-js

In tsconfig.app.json you add:

"types": [
    "office-js"
]

In main.ts you bootstrap app as:

    Office.initialize = function () {
    platformBrowserDynamic().bootstrapModule(AppModule);
};

In index.html you add:

<script type="text/javascript" src="https://appsforoffice.microsoft.com/lib/1/hosted/office.js"></script>

After that you should be able to write something like this in your angular service:

  getExtension(): string {
    if (Office.context.host === Office.HostType.Word) {
      return '.docx';
    } else if  (Office.context.host === Office.HostType.Excel) {
      return '.xlsx';
    } else if (Office.context.host === Office.HostType.PowerPoint) {
      return '.pptx';
    } else {
      return null;
    }
  }

Here you can find a sample of angular office-js project:
