How to import highcharts-more

Question

I would like to use the spiderweb chart from highcharts, which requires me to import highcharts-more, but I cannot figure out how to do that. Currently, this is how I've added highcharts to my project, from app.module.ts:

import { ChartModule } from 'angular2-highcharts';
import { HighchartsStatic } from 'angular2-highcharts/dist/HighchartsService';
import * as Highcharts from 'highcharts/highstock';

imports: [
    ChartModule
]

providers: [{
    provide: HighchartsStatic,
    useValue: Highcharts
}],

When I try to import it like this:

import * as HighchartsMore from 'highcharts/highcharts-more';

I get the following error:

Module '"c:/pdws-view-v2/node_modules/@types/highcharts/highcharts-more"' resolves to a non-module entity and cannot be imported using this construct.

Any ideas?

You don't need to use an external module to use highcharts or any of the extension packages in your Angular app. All you need to do npm install --save highcharts and then in your component along with the other imports include:

// HIGHCHARTS
import * as Highcharts from 'highcharts';
declare var require: any;
require('highcharts/highcharts-more')(Highcharts);
require('highcharts/modules/solid-gauge')(Highcharts);
require('highcharts/modules/heatmap')(Highcharts);
require('highcharts/modules/treemap')(Highcharts);
require('highcharts/modules/funnel')(Highcharts);
let chartHolder;

and example usage:

ngOnInit() {
  chartHolder = Highcharts.chart('container', newOptions);
}

and you can update the chart options:

updateChart(newOptions) {
  chartHolder.update(newOptions);
}
