ENS

This class is designed to interact with the ENS system on the Ethereum blockchain. For using ENS package, first install Web3 package using: npm i web3 or yarn add web3 based on your package manager, after that ENS features can be used as mentioned in following snippet.

import { Web3 } from 'web3';

const web3 = new Web3('https://127.0.0.1:4545');

console.log(await web3.eth.ens.getAddress('ethereum.eth'))

For using individual package install web3-eth-ens packages using: npm i web3-eth-ens or yarn add web3-eth-ens. This is more efficient approach for building lightweight applications.

import { ENS } from 'web3-eth-ens';

const ens = new ENS(undefined,'https://127.0.0.1:4545');

console.log(await ens.getAddress('vitalik.eth'));
