Getting started in EJ2 TypeScript Barcode control

3 Nov 20239 minutes to read

This section explains the steps required to create the Barcode control using TypeScript and configure its properties 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 BarcodeGenerator component in your application.

|-- @syncfusion/ej2-barcode-generator
    |-- @syncfusion/ej2-base
    |-- @syncfusion/ej2-data

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

Add Barcode to the project

Add the HTML div element for the Barcode into your index.html. [src/index.html]

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

<head>
    <title>EJ2 Barcode</title>
    <meta charset="utf-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <meta name="description" content="Typescript UI Controls" />
    <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>
     <!--container which is going to render the Barcode-->
     <div id='container'>
     </div>
</body>

</html>

Now, import the Barcode component into your app.ts to instantiate a Barcode and append the diagram instance to the #container. [src/app/app.ts]

The following example shows a basic Barcode.

import { BarcodeGenerator, ValidateEvent } from '@syncfusion/ej2-barcode-generator';

 let barcode = new BarcodeGenerator({
        width: '200px',
        height: '150px',
        mode: 'SVG',
        type: 'Codabar',
        value: '123456789',

    });
    barcode.appendTo('#element');
<!DOCTYPE html>
<html lang="en">

<head>
    <title>EJ2 Barcode-Generator</title>
    <meta charset="utf-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <meta name="description" content="Typescript UI Controls" />
    <meta name="author" content="Syncfusion" />
    <link href="index.css" rel="stylesheet" />
    <script src="https://cdnjs.cloudflare.com/ajax/libs/systemjs/0.19.38/system.js"></script>
    <script src="systemjs.config.js"></script>
<script src="https://cdn.syncfusion.com/ej2/syncfusion-helper.js" type ="text/javascript"></script>
</head>
<style>
    .barcodeStyle{
        height: 150px;
        width: 200px;
        padding-left: 40%;
        padding-top: 9%;
    }
    </style>

<body>
    <div id='loader'>Loading....</div>
    <div id='container'class="barcodeStyle">
        <div id='element'></div>
    </div>
</body>

</html>

Now, the npm run start command is used to run the application in the browser.

npm run start

Adding QR Generator control

        displayText: { visibility: false },
        mode: 'SVG',
        value: 'Syncfusion',

    });
    barcode.appendTo('#element');

You can add the datamatrix code in our barcode generator component.

import { DataMatrixGenerator, ValidateEvent } from '@syncfusion/ej2-barcode-generator';

 let barcode = new DataMatrixGenerator({
        width: '200px',
        height: '150px',
        displayText: { visibility: false },
        mode: 'SVG',
