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

Question

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:

• Error TS2497: Module '"xxxx/highcharts/modules/exporting"' resolves to a non-module entity and cannot be imported using this construct. - JIT compilation
• Cannot find module 'highcharts/modules/export-data'. - AOT compilation

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.

Answer 1

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.
