Importing Required Syncfusion Angular components to reduce bundle size


To use Syncfusion Angular Components, we need dependencies syncfusion-javaScript, jQuery and Jsrender.

The Syncfusion Angular components supports module loading. Since while importing EJAngular2Module from ej-angular2 package, it automatically loads its dependencies from npm:syncfusion-javascript package, this may cause bundle size bigger.

To reduce the bundle size import, required Angular components from ej-angular2 package, so that the bundle size will be reduced.

import { NgModule, enableProdMode, ErrorHandler } from '@angular/core';

. . . . .


import { EJ_BUTTON_COMPONENTS } from 'ej-angular2/src/ej/button.component';


import { AppComponent } from './app.component';

import { HomeComponent } from './home/home.component';

import { ButtonComponent } from './button/button.component';


import { rootRouterConfig } from './app.routes';




  imports: [

    BrowserModule, FormsModule, HttpModule, RouterModule.forRoot(rootRouterConfig, { useHash: true })


  declarations: [

    AppComponent, HomeComponent, ButtonComponent,



  bootstrap: [AppComponent]


export class AppModule { }
