How to import exporting.js and export-data.js using angular2-highcharts and AOT compiler?

I'm using angular2-highcharts and my chart works just fine, but I need to export the chart to XLS.

All I need to achieve this is doing

HighchartsExporting(Highcharts);
HighchartsExportData(Highcharts);

somewhere in the code, and the export options will show up by the chart.

The problem is how to import HighchartsExporting and HighchartsExportData properly, because the standard solution 

@NgModule({
    imports: [
      BrowserModule, 
      ChartModule.forRoot(
        require('highcharts'),
        require('highcharts/modules/exporting')
      ],

won't work with AOT, giving me some "Error encountered resolving symbol values statically" at compile time.

I can get it to work by doing 

import * as HichartsExporting from 'highcharts/modules/exporting';
import * as HighchartsExportData from 'highcharts/modules/export-data';

as suggested here, but it gives me 2 errors:

I can get around this by doing

import HichartsExporting  = require('highcharts/modules/exporting');
import HighchartsExportData = require('highcharts/modules/export-data');

as suggested here, but after AOT compilation, I get "Uncaught ReferenceError: require is not defined" at runtime.

All solutions seem to work fine in practice, I just can't compile them. Any suggestions are welcome.

Just in case this helps anyone, I couldn't do it using imports. Instead, I had to include the <script src="~/node_modules/highcharts/modules/exporting.js"> tag in my HTML. Since this JS is a self-invoking function, that's all it takes to make it work.

You can create an instance of Highcharts with all modules loaded like HighchartsModule(Highcharts) and then pass the instance to forRoot function as explained in the angular2-highcharts docs.

You should be able to load the modules using require or import.

import * as Highcharts from 'highcharts';
require('highcharts/modules/exporting')(Highcharts);

or

import * as Highcharts from 'highcharts';
import * as HC_exporting from 'highcharts/modules/exporting';
HC_exporting(Highcharts);

and next the same as in the mentioned docs:

@NgModule({
    ...
    imports: [
      BrowserModule, 
      ChartModule.forRoot(
-       require('highcharts'),
+       Highcharts
      )
    ],
})
