pockets – Webpack challenge with tiny-secp256k1 and ECPair

I’m creating a browser extension utilizing Webpack v5 and incorporating the bitcoinjs-lib and ecpair libraries to create a Bitcoin pockets. Nonetheless, I’m encountering an error when trying to load the WebAssembly module.

I’d enormously admire any steering or options on learn how to resolve this challenge efficiently and instantiate the WebAssembly module in my browser extension.

Error Message:

Listed here are the important thing particulars of my setup:

• I’m utilizing Webpack v5 to bundle the appliance.

• Error is happening when attempting to import tiny-secp256k1 and in addition when passing that occasion to ECPairFactory.

My webpack.config.js file:

const path = require("path");
const CopyPlugin = require("copy-webpack-plugin");

operate copyFolderSync(from, to) {
  fs.mkdirSync(to, { recursive: true });
  fs.readdirSync(from).forEach((component) => {
    if (component !== "manifest.json") {
      if (fs.lstatSync(path.be part of(from, component)).isFile()) {
        fs.copyFileSync(path.be part of(from, component), path.be part of(to, component));
      } else {
        copyFolderSync(path.be part of(from, component), path.be part of(to, component));
