I want to create a module related to the chart and write it elsewhere.
The source code of module declaration is as follows.
chart.module.ts
import { NgModule, ModuleWithProviders } from '@angular/core';
import { CommonModule } from '@angular/common';
import { ChartsModule } from 'ng2-charts'
import { CLineChartComponent } from './cline-chart/cline-chart.component';
import { DoughnutChartComponent } from './doughnut-chart/doughnut-chart.component';
@NgModule({
imports: [
CommonModule,
ChartsModule
],
declarations: [
CLineChartComponent,
DoughnutChartComponent
],
exports: [
CLineChartComponent,
DoughnutChartComponent
]
})
export class CustomChartModule {
static forRoot(): ModuleWithProviders {
return {
ngModule: CustomChartModule,
providers: []
}
}
}
I tried to load it using another module forRoot function only.
The source for loading modules using forRoot function is:
dashboard.module.ts
import { NgModule } from '@angular/core';
import { FormsModule } from '@angular/forms';
import { CommonModule } from '@angular/common';
import { CustomChartModule } from '@Library/chart.module';
@NgModule({
imports: [
CommonModule,
FormsModule,
CustomChartModule.forRoot()
],
declarations: [
],
exports: [
]
})
export class DashboardRootModule { }
However, when I use it like this, I get an error.
Error: Template parse errors: 'cline-chart' is not a known element:
I get an error when I try to use CLineChartComponent from a Component in the same directory as Dashboard.root.modules.
Why this error occur?
ps. i append clinechart.component.ts source.
The source is too long, so I deleted the part related to Option.
import { Component, OnInit } from '@angular/core';
@Component({
selector: 'cline-chart',
templateUrl: './cline-chart.component.html',
styleUrls: ['./cline-chart.component.css'],
})
export class CLineChartComponent implements OnInit {
constructor() { }
ngOnInit() {
}
showFlag(flag:boolean){
this.isLoad = flag;
}
setCLineChartData(dataSet:Array<any>,legendName:string,titleName:string){
//this funciton is Set Data
}
public width: number = 230;
public heigth: number = 100;
public lineChartOptions: any = {
//this Object is Chart Option
};
public lineChartColors: Array<any> = [
//this Array is Defined Line color
];
// events
public chartClicked(e: any): void {
console.log(e);
}
public chartHovered(e: any): void {
console.log(e);
}
}
app.module.ts
import { DashboardModule } from './dashboard/dashboard.module';
@NgModule({
declarations: [
//Declare
],
imports: [
DashboardModule,
//Import another
],
providers: [
//Porvider Anoter
],
bootstrap: [AppComponent]
})
export class AppModule { }
dashboard.module.ts
import { NgModule } from '@angular/core';
import { FormsModule } from '@angular/forms';
import { CommonModule } from '@angular/common';
import { DashboardComponent } from './dashboard.component';
import { DashboardRoutingModule } from './dashboard-routing.module';
import { DashboardRootComponent } from './dashboard-root/dashboard-root.component';
import { BapIframeModule } from './../shared/bap-iframe/bap-iframe.module';
import { DashboardRootModule } from './dashboard-root/dashboard-root.module'
@NgModule({
imports: [
DashboardRootModule,
CommonModule,
FormsModule,
DashboardRoutingModule,
CoreModule.forRoot(),
BapIframeModule.forRoot()
],
declarations: [
DashboardComponent,
DashboardRootComponent
],
exports: [
DashboardComponent,
DashboardRootComponent
]
})
export class DashboardModule { }
dashboard.root.module.ts
import { NgModule } from '@angular/core';
import { FormsModule } from '@angular/forms';
import { CommonModule } from '@angular/common';
import { GridPanelComponent } from './grid-panel.component/grid-panel.component'
import { GridScrollComponent } from './grid-scroll.component/grid-scroll.component'
import { CustomChartModule } from '@Libarary/chart.module';
@NgModule({
imports: [
CommonModule,
FormsModule,
CustomChartModule.forRoot(),
],
declarations: [
GridPanelComponent,
GridScrollComponent
],
exports: [
GridPanelComponent,
GridScrollComponent
]
})
export class DashboardRootModule { }

Where are you trying to use the chart component? If it is added to a component from the DashboardModule then you should export the CustomChartModule from the DashboardRootModule:
@NgModule({
...
exports: [
GridPanelComponent,
GridScrollComponent,
CustomChartModule.forRoot()
]
})
export class DashboardRootModule { }
If it is added to a component from the AppModule then you should also export the DashboardRootModule from the DashboardModule:
@NgModule({
...
exports: [
DashboardComponent,
DashboardRootComponent,
DashboardRootModule
]
})
export class DashboardModule { }
By the way the forRoot patterns makes sense only if you want to provide modules with and without providers.

Even thought CLineChartComponent
resides within the CustomChartModule
, you need to import the component in the module where you going to use it. So inside DashboardModule.ts
NgModule({
imports: [
CommonModule,
FormsModule,
CustomChartModule.forRoot()
],
declarations: [
CLineChartComponent
],
exports: [
]
})
