Web3js Deploy Contract

Process

1. Get the smart contract bytecode compiled from solc
2. Send a transaction:

const { Web3 } = require('web3');
const path = require('path');
const fs = require('fs');
 
const web3 = new Web3('http://127.0.0.1:8545/');
 
const bytecodePath = path.join(__dirname, 'MyContractBytecode.bin');
const bytecode = fs.readFileSync(bytecodePath, 'utf8');
 
const abi = require('./MyContractAbi.json');
const myContract = new web3.eth.Contract(abi);
myContract.handleRevert = true;
 
async function deploy() {
	const providersAccounts = await web3.eth.getAccounts();
	const defaultAccount = providersAccounts[0];
	console.log('Deployer account:', defaultAccount);
 
	const contractDeployer = myContract.deploy({
		data: '0x' + bytecode,
		arguments: [1],
	});
 
	const gas = await contractDeployer.estimateGas({
		from: defaultAccount,
	});
	console.log('Estimated gas:', gas);
 
	try {
		const tx = await contractDeployer.send({
			from: defaultAccount,
			gas,
			gasPrice: 10000000000,
		});
		console.log('Contract deployed at address: ' + tx.options.address);
 
		const deployedAddressPath = path.join(__dirname, 'MyContractAddress.txt');
		fs.writeFileSync(deployedAddressPath, tx.options.address);
	} catch (error) {
		console.error(error);
	}
}
 
deploy();
