NodeJS crypto module not working in browser after bundling with webpack

I keep getting the following error when I view my code in the browser:

Uncaught TypeError: crypto.createHash is not a function

I've tried loading the module during runtime using webpack:

module.exports = {
  target: "web",
  mode: "production",
  entry: "./dist/index.js",
  output: { filename: "../dist/bundle.js" },
  externals: { crypto: require("crypto") }, <=== here
};

and importing as: import * as crypto from "crypto", but this leads to the same error outlined above.

I realize that the browser has its own native crypto API and thus also tried aliasing the name to a different name like import * as crypt from "crypto", however this leads to the same error.

Repository with full code is available: https://www.github.com/lbragile/LibraCoin

Node.js core libraries are only available in node.js environments. So, if at the end, you will run your code in browser, you cannot use node core libraries.

Note that crypto is a core library

Browser crypto API is completely different as far as I know. So check out its docs
