rns-artifacts
RNS library for smart contract development.
It provides implementations of RNS Registry, Registrars, and Resolvers which you can deploy as-is or extend to suit your needs, as well as Solidity components to build custom contracts and more complex decentralized systems.
Install
npm install rns-artifacts
Usage
To write your custom contracts, import ours and extend them through inheritance.
pragma solidity ^0.5.2;
import 'rns-artifacts/contracts/registry/AbstractRNS.sol';
import 'rns-artifacts/contracts/resolver/AbstractResolver.sol';
contract MyResolver is AbstractResolver {
AbstractRNS public rns;
constructor(AbstractRNS _rns) public {
rns = _rns;
}
function supportsInterface(bytes4) public pure returns (bool) {
return false;
}
}To test your custom contracts in Truffle, import ours and deploy them through truffle-contract.
const assert = require('assert');
const truffleContract = require('truffle-contract');
const RNS = truffleContract(
require('rns-artifacts/build/contracts/RNS.json')
);
RNS.setProvider(web3.currentProvider);
const MyResolver = artifacts.require('MyResolver');
contract('RNS', async accounts => {
it('should create MyResolver', async () => {
const rns = await RNS.new({ from: accounts[0] });
const resolver = await MyResolver.new(rns.address);
const rnsAddress = await resolver.rns();
assert.equal(rnsAddress, rns.address);
});
});
