Fun with Generator Functions. First backfill XRPL Ledgers, then keep up with current Ledgers closing, fall back to backfilling if needed to sync gaps.

import { XrplClient } from 'xrpl-client'
const config = { backfillLedgers: 20, lastLedger: null }
const client = new XrplClient(['wss://xrplcluster.com'])
await client.ready()
config.lastLedger = client.getState().ledger.last - config.backfillLedgers
function getLedgerTransactions(ledger_index) {
return client.send({ command: 'ledger', transactions: true, expand: true, ledger_index })
