I am losing my mind and hair over this. I am importing HighCharts in Angular 2 but need to require some of its extra libraries. So far in my code I have
import {ChartModule} from 'angular2-highcharts';
@NgModule({
....
imports:[
ChartModule.forRoot(require('highcharts'), require('highcharts/modules/drilldown'))})
]
But I keep getting this error
ERROR in Error encountered resolving symbol values statically. Calling function 'ChartModule'. function calls are not supported. Consider replacing the function or lambda with a reference to an exported fucntion.
So I tried
export function highchartsRequire:any {
return{
require('highcharts'),
require('highcharts/modules/drilldown')
}
}
...
ChartModule.forRoot(highchartsRequire())
Still doesn't work. Any ideas?
Using angular 2 angular cli: 1.0.0-beta.30
UPDATE - got it partially working thanks to JayChase
This works
export function highchartsFactory() {
return require('highcharts');
}
But I cannot require two at a time
declare var require: any;
export function highchartsFactory() {
return function () {
require('highcharts');
require('highcharts/modules/drilldown')
};
}
@NgModule({
imports: [
ChartModule
],
providers: [
{
provide: HighchartsStatic,
useFactory: highchartsFactory
}
],
Any ideas? Thank you.
There is an issue open for this and a workaround here using an exported function.
import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { FormsModule } from '@angular/forms';
import { HttpModule } from '@angular/http';
import { ChartModule } from 'angular2-highcharts';
import { HighchartsStatic } from 'angular2-highcharts/dist/HighchartsService';
import { AppComponent } from './app.component';
declare var require: any;
export function highchartsFactory() {
const hc = require('highcharts');
const dd = require('highcharts/modules/drilldown');
dd(hc);
return hc;
}
@NgModule({
declarations: [
AppComponent
],
imports: [
BrowserModule,
FormsModule,
HttpModule,
ChartModule
],
providers: [
{
provide: HighchartsStatic,
useFactory: highchartsFactory
}
],
bootstrap: [AppComponent]
})
export class AppModule { }
