An SDK to search registered domains in the Registry Smart Contract from the SorobanDomains protocol

Installation

npm i @creit.tech/sorobandomains-sdk

The SorobanDomainsSDK class

The first step will be creating a new instance from the main class.

import * as SDK from '@stellar/stellar-sdk';
import config from './myconfigfile.ts';

const sdk: SorobanDomainsSDK = new SorobanDomainsSDK({
  stellarSDK: SDK,
  rpc: new SDK.SorobanRpc.Server(config.RPC_URL),
  network: config.NETWORK,
  vaultsContractId: config.VAULTS_CONTRACT_ID,
  valuesDatabaseContractId: config.VALUES_DATABASE_CONTRACT_ID,
  reverseRegistrarContractId: config.REVERSE_REGISTRAR_CONTRACT_ID,
  defaultFee: config.DEFAULT_FEE,
  defaultTimeout: config.DEFAULT_TIMEOUT,
  simulationAccount: config.SIMULATION_ACCOUNT,
});

If you want to know what each value represents, check the SorobanDomainsSDKParams interface in the ./src/types.ts file.

Fetch a registered domain

import { Record } from '@creit.tech/sorobandomains-sdk';

const domainRecord: Record = await sdk.searchDomain({ domain: 'jhon' });
const subDomainRecord: Record = await sdk.searchDomain({ domain: 'jhon', subDomain: 'payments' });

When searching for a domain, you can receive two types of errors: an expected error by the SDK or a simulation error. Currently, there is only one expected error by the SDK: Domain404Error.

If you need to catch this type of error you can do this:

import { Domain404Error } from '@creit.tech/sorobandomains-sdk';

try {
  const domainRecord: Record = await sdk.searchDomain({ domain: 'nonexistingrecord' });
} catch (e) {
  if (e.name === Domain404Error.name) {
    // ... Do something here
  } else {
    // ... Do this instead
  }
}

Note: In the example we check by the name and not if is an instance of the class because depending on your environment that validation method could fail.

Fetch the reverse domain of an address

Before fetching the reverse domain of an address, you need to set reverseRegistrarContractId in the SorobanDomainsSDK constructor.

import { ReverseDomain404Error } from '@creit.tech/sorobandomains-sdk';

const address = 'GAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAWHF';

try {
  const domain: string = await sdk.getReverseDomain(address);
} catch (e) {
  if (e.name === ReverseDomain404Error.name) {
    // ... Do something here
  } else {
    // ... Do this instead
  }
}
