Lesson 5 w/ ethers.js version 6

[jtsaich]

The youtube video was using version 5 of ethers.js. For people curious how contract transaction receipt is retrieved, here is the code snippet:

import { ethers } from "ethers";
import fs from "fs-extra";

async function main() {
  const provider = new ethers.JsonRpcProvider("http://127.0.0.1:7545");
  const wallet = new ethers.Wallet(
    "0x1d630b5ab24640c37af387fc8b9a2e9a1b9ab62aae00d1719f4fb6e37391ec4d",
    provider
  );

  const abi = fs.readFileSync("./SimpleStorage_sol_SimpleStorage.abi", "utf8");
  const binary = fs.readFileSync(
    "./SimpleStorage_sol_SimpleStorage.bin",
    "utf8"
  );

  const contractFactory = new ethers.ContractFactory(abi, binary, wallet);
  console.log("Deploying, please wait...");
  const contract = await contractFactory.deploy();

  const transactionReceipt = await contract.deploymentTransaction().wait(1);
  console.log("Here is the deployment transaction: ");
  console.log(contract);
  console.log("Here is the deployment receipt: ");
  console.log(transactionReceipt);
}

main()
  .then(() => process.exit(0))
  .catch((error) => {
    console.error(error);
    process.exit(1);
  });

Thank you sir, I have a question why the contract; is required?

const contract = await contractFactory.deploy();
contract;
const transactionReceipt = await contract.deploymentTransaction().wait(1);

I also got transactionReceipt by using another way of writing, is my way of writing okay?

const contract = await contractFactory.deploy();
const transactionReceipt =await (contract.deploymentTransaction()).wait();

Ah that was an accident! I'll remove that. Simply writing contract; won't affect anything the program just going to ignore that.
