27 Apr 20247 minutes to read

Sidebar can also be initialized using SystemJS as follows

Installation and configuration

To setup basic Angular sample use the following commands.

 git clone https://github.com/angular/quickstart.git quickstart
 cd quickstart
 npm install

For more information, refer to Angular sample setup.

Install Syncfusion Sidebar packages using the below command.
```
 npm install @syncfusion/ej2-angular-navigations --save
```

The above package installs Sidebar dependencies which are required to render the component in an Angular environment.

Syncfusion ej2-angular-navigations packages need to be mapped in systemjs.config.js configuration file.

/**
 * System configuration for Angular samples
 * Adjust as necessary for your application needs.
 */
(function (global) {
  System.config({
    paths: {
      // paths serve as alias
      'npm:': 'node_modules/',
      "syncfusion:": "node_modules/@syncfusion/", // syncfusion alias

    },
    // map tells the System loader where to look for things
    map: {
      // our app is within the app folder
      'app': 'app',

To render the Sidebar component, need to import Sidebar and its dependent component’s styles as given below in style.css.

@import '../../node_modules/@syncfusion/ej2-base/styles/material.css';
@import '../../node_modules/@syncfusion/ej2-angular-navigations/styles/material.css';

Note: If you want to refer the combined component styles, please make use of our CRG (Custom Resource Generator) in your application.

<div>
    <div class="title">Main content</div>
    <div class="sub-title">
        Content goes here.
    </div>
</div>

Create an Angular module and include the above Sidebar component.
In the module, declare the Component and Directives required to render the Sidebar.
Bootstrap the application with the above module.

Refer to the following snippet to import the sidebar module in app.module.ts from the @syncfusion/ej2-angular-navigations.

import { AppComponent } from './app.component';
import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';

import { SidebarModule } from '@syncfusion/ej2-angular-navigations';

@NgModule({
    imports: [SidebarModule, BrowserModule],
    declarations: [AppComponent],
    bootstrap: [AppComponent]
})
export class AppModule { }

systemjs.config.js file should be configured as described in the Installation and configuration section.

})
export class AppComponent {
    @ViewChild('sidebar') sidebar?: SidebarComponent;
    public onCreated(args: any) {
      (this.sidebar as SidebarComponent).element.style.visibility = '';
    }
}
import { bootstrapApplication } from '@angular/platform-browser';
import { AppComponent } from './app.component';
