object available in the global namespace. Both Truffle and Hardhat with Truffle make an instance of web3 available in the global scope.
npm i @lazy-sol/a-missing-gem
The package is used as a library in projects built with Truffle or Hardhat with Truffle.
Code:
// BN utils
const {
print_amt,
} = require("@lazy-sol/a-missing-jem/bn_utils");
// get the account balance as BN
const balance = await web3.eth.getBalance("0x000000000000000000000000000000000000dEaD");
// print the BN in human readable format
console.log("balance: %o ETH", print_amt(balance));
Output:
balance: '10k' ETH
// block utils
const {
extract_gas,
} = require("../include/block_utils");
// send the transaction to get the tx receipt
const receipt = await web3.eth.sendTransaction({
from: '0xde0B295669a9FD93d5F28D9Ec85E40f4cb697BAe',
to: '0x11f4d0A3c12e86B4b5F39B213F7E19D048276DAe',
value: '1000000000000000'
});
// extract the gas used
const gasUsed = extract_gas(receipt);
// print
console.log("gas used: %o", gasUsed);
Output:
gas used: 21000
