Here is a simple javascript function that converts a buffer to a hexdump string:

const hexFormat = (buffer) => {
  const arr = [];
  for (let i = 0; i < buffer.byteLength; i++) {
    if (i % 16 === 0) {
      arr.push(`\n0x${i.toString(16).padStart(10, 0)}`);
    }
    arr.push(' ', buffer.readUInt8(i).toString(16).padStart(2, 0));
  }
  return arr.join('').trim();
};
