Save Generated Barcodes

The Aspose.BarCode Cloud SDK for Node.js by the GenerateApi provides methods to generate barcodes to the Promise<{ response: HttpResponse; body: Buffer }>. Then you can work with result in order to obtain the desired outcomes. This API supports various barcode formats and configurations, enabling users to customize barcode generation to fit their needs.

Methods

  • generate: Generates a barcode via GET request.
  • generateBody: Generates a barcode via POST request with JSON or XML body.
  • generateMultipart: Generates a barcode via POST request with multipart form data. All of these methods return a Promise<{ response: HttpResponse; body: Buffer }>.

Saving the Barcode to File

Below are examples demonstrating how to save the generated barcode stream to a file.

Example: Using generate

const fs = require('fs');
const path = require('path');
const Barcode = require('aspose-barcode-cloud-node');

function makeConfiguration() {
    const envToken = process.env['TEST_CONFIGURATION_ACCESS_TOKEN'];
    if (!envToken) {
        return new Barcode.Configuration(
            'Client Id from https://dashboard.aspose.cloud/applications',
            'Client Secret from https://dashboard.aspose.cloud/applications',
            null,
            null
        );
    } else {
        return new Barcode.Configuration(
            null,
            null,
            null,
            envToken
        );
    }
}
const config = makeConfiguration();

async function generateBarcode(api, fileName) {

    const request = new Barcode.GenerateRequestWrapper(Barcode.EncodeBarcodeType.Code128, "Aspose.BarCode.Cloud");
    request.imageFormat = Barcode.BarcodeImageFormat.Png;

    const generated = await api.generate(request);

    fs.writeFileSync(fileName, generated.body);
}

const genApi = new Barcode.GenerateApi(config);
const fileName = path.resolve('testdata','Code128.jpeg');

generateBarcode(genApi, fileName)
    .then(() => {
        console.log('File \'' + fileName + '\' generated.');
    })
    .catch(err => {
        console.error("Error: " + JSON.stringify(err, null, 2));
        process.exitCode = 1;
    });

Example: Using generateBody

const fs = require('fs');
const path = require('path');
const Barcode = require('aspose-barcode-cloud-node');

function makeConfiguration() {
    const envToken = process.env['TEST_CONFIGURATION_ACCESS_TOKEN'];
    if (!envToken) {
        return new Barcode.Configuration(
            'Client Id from https://dashboard.aspose.cloud/applications',
            'Client Secret from https://dashboard.aspose.cloud/applications',
            null,
            null
        );
    } else {
        return new Barcode.Configuration(
            null,
            null,
            null,
            envToken
        );
    }
}
const config = makeConfiguration();

async function generateBarcode(api, fileName) {
    const imageParams = new Barcode.BarcodeImageParams();
    imageParams.foregroundColor = "#FF5733";
    imageParams.backgroundColor = "#FFFFFF";
    imageParams.imageFormat = Barcode.BarcodeImageFormat.Jpeg;

    const encodeData = new Barcode.EncodeData();
    encodeData.data = 'Aspose.BarCode.Cloud';
    encodeData.dataType = Barcode.EncodeDataType.StringData;

    const generateParams = new Barcode.GenerateParams();
    generateParams.barcodeType = Barcode.EncodeBarcodeType.Pdf417;
    generateParams.encodeData = encodeData;
    generateParams.barcodeImageParams = imageParams;

    const request = new Barcode.GenerateBodyRequestWrapper(generateParams);

    const generated = await api.generateBody(request);

    fs.writeFileSync(fileName, generated.body);
}

const genApi = new Barcode.GenerateApi(config);
const fileName = path.resolve('testdata','Pdf417.png');

generateBarcode(genApi, fileName)
    .then(() => {
        console.log('File \'' + fileName + '\' generated.');
    })
    .catch(err => {
        console.error("Error: " + JSON.stringify(err, null, 2));
        process.exitCode = 1;
    });

Example: Using generateMultipart

const fs = require('fs');
const path = require('path');
const Barcode = require('aspose-barcode-cloud-node');

function makeConfiguration() {
    const envToken = process.env['TEST_CONFIGURATION_ACCESS_TOKEN'];
    if (!envToken) {
