Struggling to get treeshaking build to work

[jkasperbl]

Please see this simplified example at https://stackblitz.com/edit/github-1mzjky-bfluyv?file=src/app/app.module.ts

With the current code, my sample line chart renders correctly. However, this is using a "full" echarts import which you cna see in app.module.ts:

NgxEchartsModule.forRoot({ echarts: () => import('echarts' as const) })

If you comment out that line and uncomment the line above, it will instead use my attempt at a custom build:

NgxEchartsModule.forRoot({ echarts })

When I do this, I don't get any errors, but the chart no longer renders. As far as I can tell I have all of the necessary components (I would think * from echarts/core, LineChart, and `CanvasRenderer' are all that's needed for such a simple example, but it seems likely there's something else I'm missing that I'm not aware of.

Any help would be greatly appreciated in figuring this out.

Have you updated your example? I find your code works as expected and the chart renders correctly using custom build.

@xieziyu Thanks for the response! However, no, I have not updated my example. The example code shows it working with a "full" import -- to see the issue, uncomment the top NgxEchartsModule line and comment out the one below it. Or just replace the entire contents of app.module.ts with this:

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import * as echarts from 'echarts/core';
import { LineChart } from 'echarts/charts';
import {
  GridComponent,
  LegendComponent,
  TitleComponent,
  ToolboxComponent,
  TooltipComponent,
} from 'echarts/components';
import { CanvasRenderer } from 'echarts/renderers';
import { NgxEchartsModule } from 'ngx-echarts';
import { AppComponent } from './app.component';
import { ChartComponentModule } from './chart/chart.component';

echarts.use([
  CanvasRenderer,
  GridComponent,
  LegendComponent,
  LineChart,
  TitleComponent,
  ToolboxComponent,
  TooltipComponent,
]);

@NgModule({
  declarations: [AppComponent],
  imports: [
    BrowserModule,
    ChartComponentModule,
    NgxEchartsModule.forRoot({ echarts })
  ],
  providers: [],
  bootstrap: [AppComponent],
})
export class AppModule {}
