Create Slider in Angular Application using Web pack

To quick start with Syncfusion JavaScript Angular components run the below commands to clone the repository for Web pack starter and installing required dependency packages.

JAVASCRIPT

> git clone https://github.com/syncfusion/angular2-seeds

 > cd angular2-seeds

 > npm install

The below steps describes to add slider component with above cloned seed application.

Syncfusion JavaScript components source configuration and sample creation

• Copy required Syncfusion Angular source component(s) from the below build location and add it in src/app/ej folder.

JAVASCRIPT

(Installed Location)\Syncfusion\Essential Studio\14.3.0.49\JavaScript\assets-src\angular2\

NOTE

core.ts file is mandatory for all Syncfusion JavaScript Angular components. The repository having the source file from Essential Studio for JavaScript v14.3.0.49.

• Create slider folder inside src/app folder.

• Create slider.component.html view file inside src/app/slider folder and render ejSlider Angular component using the below code example.

HTML

<ej-slider width="100%" [value]="value"></ej-slider>

• Create slider.component.ts model file inside the folder src/app/slider and create slider sample component using the below code example.

JAVASCRIPT

import { Component, ViewEncapsulation } from '@angular/core';

@Component({
  selector: 'ej-app',
  templateUrl: './slider.component.html'
})
export class SliderComponent { 
    value: string;
    constructor() {
        this.value = '20';
    }
}

Configure the routes for the Router

Before adding router configuration for above created ejSlider component, we recommend you to go through the Angular Routing configuration to get the deeper knowledge about Angular routing.

• Now, we are going to configure the route navigation link for created Slider sample in src/app/app.component.html file.

HTML

<div>
	<ul class="nav navbar-nav">
		. . . .
	<li><a data-toggle="collapse" data-target="#skeleton-navigation-navbar-collapse.in" 
    href="#slider" [routerLink]="['/slider']">Slider </a></li>
	</ul>
</div>
<main>
	<router-outlet></router-outlet>
</main>

• Import the ejSlider sample component and define the route in src/app/app.routes.ts file.

JAVASCRIPT

import { Routes } from '@angular/router';
. . . . 
import { SliderComponent } from './slider/slider.component';

export const rootRouterConfig: Routes = [
    { path: '', redirectTo: 'home', pathMatch: 'full' },
    . . . . 
    { path: 'slider', component: SliderComponent }
];

• Import and declare the Syncfusion source component and ejSlider sample component into app.module.ts like the below code snippet.

JAVASCRIPT

import { NgModule, enableProdMode, ErrorHandler } from '@angular/core';
. . . . . 
import { EJAngular2Module } from 'ej-angular2';
import { AppComponent } from './app.component';
import { SliderComponent } from './slider/slider.component';

import { rootRouterConfig } from './app.routes';
. . . . 
@NgModule({
  imports: [BrowserModule, FormsModule, HttpModule, EJAngular2Module.forRoot(), 
  RouterModule.forRoot(rootRouterConfig, { useHash: true })],
  declarations: [. . . . , SliderComponent],
  bootstrap: [AppComponent]
})
export class AppModule { }

Running the application

• To run the application, execute below command.

JAVASCRIPT

npm start

• Browse to http://localhost:3000 to see the application. And navigate to Slider tab. The component is rendered as like the below screenshot. You can make changes in the code found under src folder and the browser should auto-refresh itself while you save files.

NOTE

if you want to use other port, open package.json file, then change port in --port 3000 script and also change the port in config/webpack.dev.js.

Create Slider in Angular Application using SystemJS
