Getting started with JavaScript Barcode control

This section explains the steps required to create a simple diagram and demonstrates the basic usage of the diagram control.

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

Installation and Configuration

  • To get started with the BarcodeGenerator component, clone the Essential JS 2 quickstart project and install necessary packages by using the following commands.
git clone https://github.com/syncfusion/ej2-quickstart.git quickstart
cd quickstart
npm install
  • BarcodeGenerator packages should be mapped in the system.config.js configuration file.
System.config({
    paths: {
        'syncfusion:': './node_modules/@syncfusion/',
    },
    map: {
        app: 'app',

        //Syncfusion packages mapping
        "@syncfusion/ej2-base": "syncfusion:ej2-base/dist/ej2-base.umd.min.js",
        "@syncfusion/ej2-data": "syncfusion:ej2-data/dist/ej2-data.umd.min.js",
        "@syncfusion/ej2-navigations": "syncfusion:ej2-navigations/dist/ej2-navigations.umd.min.js",
        "@syncfusion/ej2-inputs": "syncfusion:ej2-inputs/dist/ej2-inputs.umd.min.js",
        "@syncfusion/ej2-popups": "syncfusion:ej2-popups/dist/ej2-popups.umd.min.js",
        "@syncfusion/ej2-buttons": "syncfusion:ej2-buttons/dist/ej2-buttons.umd.min.js",
        "@syncfusion/ej2-lists": "syncfusion:ej2-lists/dist/ej2-lists.umd.min.js",
        "@syncfusion/ej2-splitbuttons": "syncfusion:ej2-splitbuttons/dist/ej2-splitbuttons.umd.min.js",
        "@syncfusion/ej2-barcode-generator": "syncfusion:ej2-barcode-generator/dist/ej2-barcode-generator.umd.min.js",
    },
    packages: {
        'app': { main: 'app', defaultExtension: 'js' }
    }
});

The project is preconfigured with common settings (src/styles/styles.css, system.config.js) to start with all Essential JS 2 components.

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" />

    <!--Style reference from app-->
    <link href="/styles/styles.css" rel="stylesheet" />

    <!--System js reference and configuration-->
    <script src="node_modules/systemjs/dist/system.src.js" type="text/javascript"></script>
    <script src="system.config.js" type="text/javascript"></script>
    <link href="index.css" rel="stylesheet" />
    <script src="https://cdnjs.cloudflare.com/ajax/libs/systemjs/0.19.38/system.js"></script>
    </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.

index.ts
index.html
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>
</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
