hardhat-boilerplate-with-typescripted-contracts-artifacts v0.0.7

hardhat-boilerplate-with-typescripted-contracts-artifacts

Package consists of following artifacts useful for Token contract interaction:

• contracts/ - json artifacts of the contracts. Useful contract abi are here,
• typechain-types/ - typechain-types of all contracts optional,
• frontend-clients - frontend oriented classes those need only optional signer and abi to initiate and then used to interact with contract logic. Kinda API with the contracts in the blockchain.

Install

npm i hardhat-boilerplate-with-typescripted-contracts-artifacts

Example Repo Code

Script code that you may run with ts-node <script.ts> is below:

import {Token} from "hardhat-boilerplate-with-typescripted-contracts-artifacts/dist/typechain-types";
import {ethers} from "ethers";
// For the line below "resolveJsonModule": true policy should be used.
import ZkTurkArtifacts
    from "hardhat-boilerplate-with-typescripted-contracts-artifacts/dist/contracts/ZkTurk.sol/ZkTurk.json";
import {
    TokenContractClient
} from "hardhat-boilerplate-with-typescripted-contracts-artifacts/dist/frontend-clients/TokenContractClient";

// ZkTurk contract deployed address (You should know the address).
const contractAddress = "0x5FbDB2315678afecb367f032d93F642f64180aa3"
// Hardhat network localhost (You should have node available on rpc).
const rpcProviderUrl = "http://localhost:8545"

async function workWithFrontendClientExample() {
    // Bad example of how to use wallet from a private key.
    const privateKeyFoo = "0x59c6995e998f97a5a0044966f0945389dc9e86dae88c7a8412f4603b6b78690d"  // From Hardhat network.
    const provider = new ethers.providers.JsonRpcProvider(rpcProviderUrl)  // harhdat localhost
    const signer = new ethers.Wallet(privateKeyFoo, provider);

    // RM ts-ignore if uses real frontend provider, like commented below:
    // const provider = new ethers.providers.Web3Provider(window.ethereum);
    // const signer = provider.getSigner()
    // @ts-ignore
    const client = new TokenContractClient(signer, ZkTurkArtifacts.abi, contractAddress)

    console.log('client.transfer()', await client.transfer('0x8626f6940E2eb28930eFb4CeF49B2d1F2C9C1199', 1))
}


async function workWithContractExample() {
    const provider = new ethers.providers.JsonRpcProvider(rpcProviderUrl)
    const contractInstance = new ethers.Contract(contractAddress, ContractArtifacts.abi, provider) as Token;

    // Signer is not needed for contract call
    console.log('await contractInstance.owner()', await contractInstance.owner())
}


async function main() {
    console.log('Starting...')
    await workWithContractExample()
}

main().catch((error) => {
    console.error(error);
    process.exitCode = 1;
});
