Getting started in EJ2 TypeScript Barcode control

10 Feb 20269 minutes to read

This section explains how to create the BarcodeGenerator using TypeScript and configure it with the Essential® JS 2 quickstart (webpack) seed repository.

This application uses webpack.config.js and requires Node.js v14.15.0 or later and the webpack-cli. For more information about webpack, see 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 a command prompt in the directory where you want to clone the repository, then 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 project’s package.json file. Install dependencies with:

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='element'>
     </div>
</body>

</html>

Now, import the Barcode component into your app.ts to instantiate a BarcodeGenerator and append the instance to #element (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>

Run the application in the browser with:

npm run start

Adding QR Generator control

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

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

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

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

<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" />

</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>

Adding Datamatrix Generator control

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',
        value: 'Syncfusion',

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