You can use any third-party library as usual to connect to Ethereum node. There's example of using Web3.js.
import Web3 from 'web3';
const networkURL = 'https://eth.gateway.whoisens.org';
const name = 'whoisens.eth';
(async () => {
const web3 = new Web3(Web3.givenProvider || networkURL);
const forwardResolve = await web3.eth.ens.getAddress(name);
console.log('Forward Resolve', forwardResolve);
const contentHash = await web3.eth.ens.getContenthash(name);
console.log('Content hash', contentHash);
})();You can install your own instance of that node. Please see INSTALL.md
