Getting started in EJ2 TypeScript Carousel control

17 Dec 20249 minutes to read

This section explains how to create a simple JavaScript Carousel and configure its available functionalities in TypeScript using Essential JS 2 quickstart seed repository.

This application is integrated with the webpack.config.js configuration and uses the latest version of the webpack-cli. It requires node v14.15.0 or higher. For more information about webpack and its features, refer to the webpack documentation.

Dependencies

The following list of dependencies are required to use the Carousel component in your application.

|-- @syncfusion/ej2-navigations
    |-- @syncfusion/ej2-base
    |-- @syncfusion/ej2-buttons

Set up development environment

Open the command prompt from the required directory, and run the following command to clone the Syncfusion JavaScript (Essential JS 2) quickstart project from GitHub.

git clone https://github.com/SyncfusionExamples/ej2-quickstart-webpack- ej2-quickstart

After cloning the application in the ej2-quickstart folder, run the following command line to navigate to the ej2-quickstart folder.

cd ej2-quickstart

Add Syncfusion JavaScript packages

Syncfusion JavaScript (Essential JS 2) packages are available on the npmjs.com public registry. You can install all Syncfusion JavaScript (Essential JS 2) controls in a single @syncfusion/ej2 package or individual packages for each control.

The quickstart application is preconfigured with the dependent @syncfusion/ej2 package in the ~/package.json file. Use the following command to install the dependent npm packages from the command prompt.

npm install

Import the Syncfusion CSS styles

To render Carousel component, need to import navigations and its dependent components styles as given below in the ~/src/styles/styles.css file, as shown below:

@import "../../node_modules/@syncfusion/ej2-base/styles/material.css";
@import "../../node_modules/@syncfusion/ej2-buttons/styles/material.css";
@import "../../node_modules/@syncfusion/ej2-navigations/styles/material.css";

Open the application in Visual Studio Code and add the Syncfusion JavaScript UI controls.

Add the HTML div tag with the id attribute as carousel to your index.html file.

Import the Carousel component in your app.ts file and initialize it with the #carousel.

[src/app/app.ts]

import { Carousel } from "@syncfusion/ej2-navigations";

const carouselObj = new Carousel({
  items: [
    { template: '<figure class="img-container"><img src="https://ej2.syncfusion.com/products/images/carousel/cardinal.png" alt="cardinal" style="height:100%;width:100%;" /><figcaption class="img-caption">Cardinal</figcaption></figure>' },
    { template: '<figure class="img-container"><img src="https://ej2.syncfusion.com/products/images/carousel/hunei.png" alt="kingfisher" style="height:100%;width:100%;" /><figcaption class="img-caption">Kingfisher</figcaption></figure>' },
    { template: '<figure class="img-container"><img src="https://ej2.syncfusion.com/products/images/carousel/costa-rica.png" alt="keel-billed-toucan" style="height:100%;width:100%;" /><figcaption class="img-caption">Keel-billed-toucan</figcaption></figure>' },
    { template: '<figure class="img-container"><img src="https://ej2.syncfusion.com/products/images/carousel/kaohsiung.png" alt="yellow-warbler" style="height:100%;width:100%;" /><figcaption class="img-caption">Yellow-warbler</figcaption></figure>' },
    { template: '<figure class="img-container"><img src="https://ej2.syncfusion.com/products/images/carousel/bee-eater.png" alt="bee-eater" style="height:100%;width:100%;" /><figcaption class="img-caption">Bee-eater</figcaption></figure>' }
  ],
});
carouselObj.appendTo("#carousel");

    { template: '<figure class="img-container"><img src="https://ej2.syncfusion.com/products/images/carousel/hunei.png" alt="kingfisher" style="height:100%;width:100%;" /><figcaption class="img-caption">Kingfisher</figcaption></figure>' },
    { template: '<figure class="img-container"><img src="https://ej2.syncfusion.com/products/images/carousel/costa-rica.png" alt="keel-billed-toucan" style="height:100%;width:100%;" /><figcaption class="img-caption">Keel-billed-toucan</figcaption></figure>' },
