tns-resolver v2.0.4

Theta Name Service - TNS Resolver

This NPM can be used to retrieve an address from a TNS or a TNS from an address on the Theta Blockchain.

It can also retrieve a list of domain names from a list of addresses.

Installation

To install tns-resolver use the following statement:

npm install tns-resolver

Import and instanciate TNS

To import and instanciate tns-resolver use the following statement:

import TNS from "tns-resolver";

const tns = new TNS();

Get domain name from an address

To get the domain name from an address use the getDomainName function such as:

import TNS from 'tns-resolver';

const address = '0x123...';
const tns = new TNS();
const domainName = await tns.getDomainName(address);
console.log(domainName);
/* will return the domain name 
 or null if no domain name is assigned to this address
 i.e. will log 'domainname.theta' or null */

Get address from a domain name

To get the address from a domain name use the getAddress function such as:

import TNS from 'tns-resolver';

const domainName = 'test.theta';
const tns = new TNS();
const address = await tns.getAddress(domainName);
console.log(address);
/* will return the address or null if the domain
is not assigned to an address
i.e. will log '0x123...' or null */

Get domain names for a list of addresses

If you need to process many addresses (eg: showing domain names of transaction histories), use the getDomainNames function such as:

import TNS from 'tns-resolver';

const addresses = ['0x123...', '0x456...'];
const tns = new TNS();
const domainNames = await tns.getDomainNames(addresses);
console.log(domainNames);
/* will return an object where the key is the address
 and the value is the domain name or an empty string if no domain name is assigned on this address
 i.e. will log { "0x123...": "domainname.theta", "0x456...": "" } */

Instanciate TNS with a custom RPC endpoint

To instanciate tns-resolver using a custom RPC endpoint use the following statement:

import TNS from "tns-resolver";

const tns = new TNS({customRpcEndpoint: 'YOUR_CUSTOM_RPC_ENDPOINT_HERE'});
