Call Batching

You will often need to make several RPC calls to get the information you need. id.js uses on-chain resolvers to make resolving records faster. It also coalesces lookups into a single eth_call when possible. This process is done seamlessly. To take advantage of it, batch your calls using Promise.all or Promise.allSettled. Requests made within a few ms will create a single in-flight eth_call. You can even combine your own API calls and await all of them!

import { Id } from '@imperviousinc/id';
import { BrowserProvider, Contract, parseEther } from 'ethers';

const provider = new BrowserProvider(...); // get a provider
const network = await provider.getNetwork() ;

const id = new Id({network, provider});

// Single in-flight call
const results = await Promise.all([
  id.getPrice('mycoolname.eth', 365*24*60*60),
  id.getOwner('vitalik.eth'),
  id.getAddress('live.forever'),
  id.getDns('impervious.forever', {name:'_443._tcp.impervious.forever', type: 'TLSA'}),
  id.getRegistration('vitalik.eth'),
  id.getText('vitalik.eth', 'url')
]);
