Fetching single account from web3.eth

Question

I'm trying to fetch the first account using web3.eth.accounts[0] using Truffle, but couldn't seem to make it work.

I'm using version 0.5.0. I read that the command is deprecated and have to use web3.eth.getAccounts() for asynchronous execution. The latter only displays an array of accounts connected to the local network.

How do I get a single account in this case? I wanted to pass { from: web3.eth.accounts[0] } metadata to a public function in my contract.

Answer 1

Try this:

async function getAccount(id) {
    let accounts = await web3.eth.getAccounts();
    return accounts[id];
}

You'll need to execute await getAccount(0) from an async function of course (or use a Promise).
