Help with Bundling Etcher-SDK Using Webpack

Hi ,

I’m trying to bundle a flash program using the Etcher-SDK with Webpack, but I’m running into an issue with the xxhash-addon during the bundling process. Specifically, I get the following error:

ERROR in ./node_modules/xxhash-addon/xxhash-addon.js

Code I’m Trying to Bundle

const sdk = require("etcher-sdk");

async function handleOSFlash(
  sourceImgPath,
  destinationsPath,
  verify = false,
  numBuffers = 16
) {
  function onFail(error) {
    console.error("Failed to write:", error);
  }
  function onProgress(state) {
    console.log("Progress:", state);
  }

  try {
    console.log(sourceImgPath, destinationsPath, verify);

    const source = new sdk.sourceDestination.File({
      path: sourceImgPath,
    });

    const destinationNew = new sdk.sourceDestination.BlockDevice({
      drive: JSON.parse(destinationsPath),
      write: true,
      direct: true,
      unmountOnSuccess: false,
      keepOriginal: false,
    });

    await sdk.multiWrite.pipeSourceToDestinations({
      source: source,
      destinations: [destinationNew],
      onFail: onFail,
      onProgress: onProgress,
      verify: verify,
      numBuffers: numBuffers,
    });
  } catch (error) {
    console.error("Error while flashing", error);
  }
}

if (require.main === module) {
  const args = process.argv.slice(2);
  if (args.length !== 3) {
    console.error("Missing params <imagePath> <drive> <verify>");
    process.exit(1);
  }
  handleOSFlash(args[0], args[1], args[2]);
}

module.exports = handleOSFlash;

Webpack Configuration

const path = require('path');

module.exports = {
    entry: './flashonSDK.js',
    output: {
        filename: 'bundle.js',
        path: path.resolve(__dirname, 'dist'),
        libraryTarget: 'commonjs2',
    },
    target: 'node',
    mode: 'production',
    externals: {
        'winusb-driver-generator': 'commonjs winusb-driver-generator',
    },
    module: {
        rules: [
            {
                test: /\.node$/,
                use: 'node-loader', 
            },
        ],
    },
};

Problem Description

I’m able to run the script in a non-bundled format, but when trying to bundle it using Webpack, I hit the following error:

ERROR in ./node_modules/xxhash-addon/xxhash-addon.js

It seems related to xxhash-addon, which is used by etcher-sdk. Has anyone successfully bundled etcher-sdk using Webpack or had similar issues with native modules like xxhash-addon?

Any guidance or suggestions on how to resolve this issue would be greatly appreciated. I’m wondering if there’s a way to get an Etcher-SDK package as a pre-bundled file (e.g., bundle.js) using Webpack or another approach.

Thanks in advance for your help!
