Challenges Encountered When Setting up ng2-charts and chart.js in a Separate Angular Component

Currently, I am in the process of working on an Angular project that involves incorporating charts using ng2-charts and chart.js. However, I have hit a roadblock with dependency resolution problems. Here is an overview of the situation:

Current Configuration: Angular Version: [Your Angular Version, e.g., Angular 15] chart.js Version: 4.4.5 ng2-charts Version: 6.0.1 Steps Taken: Initially, I installed chart.js and ng2-charts using the following commands:

npm install chart.js npm install ng2-charts --save

Following the installation, I encountered the error message below:

Module '"ng2-charts"' has no exported member 'NgChartsModule'.ts(2305)

I attempted to downgrade chart.js to version 3.0.0 to align with the required dependency but faced this error:

npm error ERESOLVE unable to resolve dependency tree

Current Project Structure: The component utilizing the charts is set up as a standalone component:

import { Component } from '@angular/core';
import { NgChartsModule } from 'ng2-charts';

@Component({
    selector: 'app-dashboard',
    standalone: true,
    templateUrl: './dashboard.component.html',
    imports: [NgChartsModule],
})
export class DashboardComponent {
    // Component logic...
}

Queries: What are the compatible versions of ng2-charts and chart.js that should be used together? How can I address the dependency issues ensuring they are compatible? Is there a specific method for configuring charts in a standalone component within Angular? I had anticipated smooth integration between ng2-charts and chart.js without complications, enabling me to effortlessly create and display charts in my Angular application. My hope was that downgrading the versions would eliminate any compatibility hurdles.

Actual Outcome: Instead of successfully incorporating the charts, I encountered several errors hindering the progress of my project. The initial import issue along with subsequent dependency resolution problems acted as obstacles, impeding the implementation of chart functionality in my application.

Answer №1

When utilizing the most recent version of ng2-charts, the module has been removed and now relies on standalone imports.

For detailed information, refer to their npm page -> ng2charts - npm

To begin, install the necessary dependencies.

npm install chart.js npm install ng2-charts --save

Next, include the required providers for ng2-charts in either your main.ts or the providers array of app.module.ts.

main.ts

import { provideCharts, withDefaultRegisterables } from 'ng2-charts';

bootstrapApplication(AppComponent, {
  providers: [provideCharts(withDefaultRegisterables())],
}).catch((err) => console.error(err));

app.module.ts

import { provideCharts, withDefaultRegisterables } from 'ng2-charts';

@NgModule({
  providers: [provideCharts(withDefaultRegisterables())],
  bootstrap: [AppComponent],
})
export class AppModule {}

Afterwards, simply import the directive into the imports array of a standalone component or module to start using it.

import { BaseChartDirective } from 'ng2-charts';

@Component({
  standalone: true,
  imports: [BaseChartDirective],
})
export class MyComponent {}
