Installation Options

You can install the product in two main ways:

1. Install via npm

The recommended way is to install the package from npm:
Aspose.BarCode for Node.js on npm

npm install aspose.barcode

or specific version

npm i aspose.barcode@25.6.0

The library will be installed to node_modules.

2. Manual ZIP Installation

If you do not want to use npm to install the package, you can download Aspose.BarCode for Node.js via Java as a ZIP archive from the
official Aspose website.

1. Download the ZIP file and extract its contents. This archive contains:

doc — API documentation license — End User License Agreement and third-party licenses libs — Java JAR file and supporting files examples — code examples readme.txt — general instructions

2. Copy the extracted folder (for example, libs or barcode-lib) into your project directory.
   You can rename it if you wish (for example, to barcode-lib).

   Example project structure:

 
    your-project/
    ├── barcode-lib/
    │ ├── index.js
    │ └── lib/
    │ ├── AsposeBarcode.js
    │ ├── ...other .js files
    │ └── aspose-barcode-nodejs-25.5.jar
    ├── node_modules/
    ├── package.json
    ├── index.js
    └── ...

3. Add the required dependency to your project’s package.json if it is not already there:

"dependencies": {
  "java": "^0.12.1"
}

Then run:

npm install

4. Use the library in your code:

const { AsposeBarcode } = require('./barcode-lib');
const { BarcodeGenerator, EncodeTypes, BarCodeImageFormat, BarCodeReader, License } = AsposeBarcode;
const license = new License();
license.setLicense('Aspose.BarCode.NodeJsviaJava.lic');
const generator = new BarcodeGenerator(EncodeTypes.CODE_11, "12345678");
const base64Image = generator.generateBarCodeImage(BarCodeImageFormat.PNG);
const reader = new BarCodeReader(base64Image);
const resultsArray = reader.readBarCodes();
const barCodeResult = resultsArray[0];
console.log("codeText", barCodeResult.getCodeText());
console.log("codeType", barCodeResult.getCodeTypeName());
process.exit(0);
