Node.js: How do you implement database transactions in Node.js?

1async function transferMoney(fromId, toId, amount) {
2    const client = await pool.connect();
3    try {
4        await client.query("BEGIN");
5
6        await client.query(
7            "UPDATE accounts SET balance = balance - $1 WHERE id = $2",
8            [amount, fromId]
9        );
10
11        await client.query(
12            "UPDATE accounts SET balance = balance + $1 WHERE id = $2",
13            [amount, toId]
14        );
15
16        await client.query("COMMIT");
17    } catch (err) {
18        await client.query("ROLLBACK");
19        throw err;
20    } finally {
21        client.release();
22    }
23}

1await knex.transaction(async (trx) => {
2    await trx("accounts").where("id", fromId).decrement("balance", amount);
3    await trx("accounts").where("id", toId).increment("balance", amount);
4});
