  suffix: 'IC', // IC | ICP | TICP
  mode: 'production' // local | production
});

// get records
client.getRecordsOfName('helloworld.ic').then(records => {
  // get ICP address(principal)
  const principal = records.find(r => r[0] === 'principal.icp');
  console.debug(`helloworld.ic's principal is ${principal}`);

  // get ICP address(account id)
  const accountId = records.find(r => r[0] === 'account_id.icp');
  console.debug(`helloworld.ic's account id is ${accountId}`);

  // get twitter

// get reverse resolve
const thePrincipal = Principal.fromText(
  'v2xhg-um7x6-mhni4-sgqsc-qarqs-bgoyy-ngobl-qoe7c-7a4cm-bvn4f-pqe'
);

client.getReverseResolve(thePrincipal).then(name => {
  if (name) console.debug(`reverse resolve name is ${name}`);
  else console.debug(`reverse resolve name not exist`);
