Getting Started with EJ2 TypeScript Chips control

7 May 20256 minutes to read

This section explains how to create a simple Chip and configure its available functionalities in TypeScript, using the 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 list of dependencies required to use the Chips control in your application is given below:

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

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 Chip control, need to import Button and its dependent controls styles as given below in the ~/src/styles/styles.css file, as shown below:

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

Add Chip to the project

Add the HTML <div> element for Chip control to your index.html file.

[src/index.html]

index.html
<!DOCTYPE html>
<html lang="en">

<head>
    <title>Essential JS 2</title>
    <meta charset="utf-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0, user-scalable=no" />
    <meta name="description" content="Essential JS 2" />
    <meta name="author" content="Syncfusion" />
    <link rel="shortcut icon" href="resources/favicon.ico" />
    <link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet" />
</head>

<body>
    <div>
        <!--Element which is going to render-->
        <div id="chip"></div>
    </div>

</body>

</html>

Then, import the Chip control in your app.ts file, and initialize it with the #chip.

[src/app/app.ts]

app.ts
import { ChipList } from '@syncfusion/ej2-buttons';

// Initialize and Render Chip control

new ChipList({ chips: ["Janet Leverling"]}, '#chip');

Run the application

Run the application in the browser using the following command:

npm start

The following example shows a basic Chip control.

index.ts
index.html
styles.css
import { ChipList } from '@syncfusion/ej2-buttons';

// Initialize and Render Chip control
new ChipList({ chips: ["Janet Leverling"] }, '#chip');
