Ways to require in Common JS

Note

As base58 v2.0.0 is an ESM module if you need to require it in a Common JS package, then you can require like this:

(async function () {
  const { base58_to_binary, binary_to_base58 } = await import("base58-js");
  console.log(
    binary_to_base58(base58_to_binary("Thequickbrownfoxjumpedoverthea1zydog"))
  );
})();

The logged output was Thequickbrownfoxjumpedoverthea1zydog.
