Using ActiveReportsJS Report Designer Component in Angular applications

Create Angular Application

The easiest and recommended way for creating a new Angular application is to use Angular CLI. Run the following command from the command prompt or terminal to create an Angular application with default options. For details, see options page of the Angular documentation.

ng new arjs-angular-designer-app --defaults --no-standalone

Install ActivereportsJS npm packages

The Angular Report Designer Component is distributed via @mescius/activereportsjs-angular npm package, which depends on the core @mescius/activereportsjs package. To install both, run:

npm install @mescius/activereportsjs-angular@latest

Or with Yarn:

yarn add @mescius/activereportsjs-angular@latest

Import ActiveReportsJS styles

Open the src/styles.css file and add the following code.

It imports the default Report Designer Component Styles

@import "@mescius/activereportsjs/styles/ar-js-ui.css";
@import "@mescius/activereportsjs/styles/ar-js-designer.css";

Register ActivereportsJS Angular module

The following steps are applicable for Angular v20. If you are using an earlier version, the steps are similar, but the file names and structure may be slightly different.

Open the src/app/app-module.ts file and replace its content with the following code

import { NgModule, provideBrowserGlobalErrorListeners } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { ActiveReportsModule } from '@mescius/activereportsjs-angular';
import { AppRoutingModule } from './app-routing-module';
import { App } from './app';

@NgModule({
  declarations: [
    App
  ],
  imports: [
    BrowserModule,
    AppRoutingModule,
    ActiveReportsModule
  ],
  providers: [
    provideBrowserGlobalErrorListeners()
  ],
  bootstrap: [App]
})
export class AppModule { }

Add ActiveReportsJS report to the application

ActiveReportsJS uses JSON format and rdlx-json extension for report template files.

In the public folder, create the new file called report.rdlx-json and insert the following JSON content into that file.

{
  "Name": "Report",
  "Body": {
    "ReportItems": [
      {
        "Type": "textbox",
        "Name": "TextBox1",
        "Value": "Hello, ActiveReportsJS Designer",
        "Style": {
          "FontSize": "18pt"
        },
        "Width": "8.5in",
        "Height": "0.5in"
      }
    ]
  }
}

Add ActivereportsJS Angular Report Designer to the application

The following steps are applicable for Angular v20. If you are using an earlier version, the steps are similar, the file names and structure may be slightly different.

Open src/app/app.ts and replace its content with the following code. The template of the component uses the Angular Report Designer Component. The designer component's input report property points to the report.rdlx-json that you created on the previous step.

import { Component, ViewChild  } from '@angular/core';
import {
  AR_EXPORTS,
  HtmlExportService,
  PdfExportService,
  ViewerComponent,
  TabularDataExportService,
} from '@mescius/activereportsjs-angular';

@Component({
  selector: 'app-root',
  template: '<div id="designer-host"><gc-activereports-designer [report]="report"> </gc-activereports-designer></div>',
  standalone: false,
  styleUrl: './app.css',
  providers: [
    {
      provide: AR_EXPORTS,
      useClass: PdfExportService,
      multi: true,
    },
    {
      provide: AR_EXPORTS,
      useClass: HtmlExportService,
      multi: true,
    },
    {
      provide: AR_EXPORTS,
      useClass: TabularDataExportService,
      multi: true,
    },
  ],  
})
export class App {
  report = { id: 'report.rdlx-json', displayName: 'my report' };
}

Add styles for the designer host element to src/app/app.css

#designer-host {
  width: 100%;
  height: 100vh;
}

Run and test the application

Run the npm start or yarn start command to start the application and open the browser to the target URL.

The ActiveReportsJS Designer component will appear on the start page of the application and display the report design. Test the basic functionality by adding report items, setting their properties, creating the data source, et cetera. Visit the Developer Guide and the Online Demo for more information on how to use the Report Designer component.
