isValidDomain

This function takes a domain string, normalizes it, checks that it is not a subdomain, is an "og" domain, and verifies that isn't too long.

function isValidDomain(_name: string): [boolean, string]

Usage

MyComponent.tsx

import { lnr } from '@linagee/lnr-ethers-react';

const MyComponent = () => {
    const domainString = "0xhal.og";

  return (
    <div>
      <h1>{lnr.utils.isValidDomain(domainString)[0] ? "Valid Domain" : "Invalid Domain"}</h1>
    </div>
  );
};

export default MyComponent;

The above code will render the following:
