Simple conversion between name and uint64 with eosjs

eosjs-name.ts

import { Serialize } from 'eosjs';

const types = Serialize.createInitialTypes();

const nameToUint64 = (name: string): string => {
  let ser = new Serialize.SerialBuffer();
  ser.pushName(name);
  return types.get('uint64').deserialize(ser);
};

const uint64ToName = (num: string): string => {
  let ser = new Serialize.SerialBuffer();
  types.get('uint64').serialize(ser, num);
  return ser.getName();
}

const eosioNum = nameToUint64('eosio');
console.log(eosioNum);

console.log(uint64ToName(eosioNum));
