const Transaction = require("swtc-transaction").Transaction // cjs import
// or
import { Transaction } from "swtc-transaction" // esm import

Using swtc-transaction

• const tx = Transaction.buildPaymentTx(options)
• const tx = Transaction.buildPaymentTx(options, remote={})
• const tx = Transaction.buildPaymentTx(options, remote={_axios: axios.create({})})
• const tx = Transaction.buildOfferCreateTx(options, remote={})
• const tx = Transaction.buildOfferCancelTx(options, remote={})
• local sign and submit

tx.addMemo() // optional
tx.setSecret("s......................")
tx.setSequence(100) // optional, automatic during signing
tx.sign(callback) // async function
tx.submitApi() // returns promise

example

> tx = TX.buildPaymentTx({source: DATA.address, to: DATA.address2, amount: {value: 0.1, currency: 'SWT', issuer: ''}})
