Typescript Example with AlgoSDK

First install the AlgoSDK. You can find the full documentation here: https://github.com/algorand/js-algorand-sdk. Here a code sample to generate a signature via the DFNS TypeScript SDK: 
import { Algodv2, encodeObj, makePaymentTxnWithSuggestedParamsFromObject } from 'algosdk'

const walletId = 'wa-6lbfv-9esgj-xxxxxxxxxxxxxxxx'
const wallet = await dfnsClient.wallets.getWallet({ walletId })

const algod = new Algodv2(ALGORAND_TOKEN, ALGORAND_NODE_URL)

const suggestedParams = await algod.getTransactionParams().do()
const transaction = makePaymentTxnWithSuggestedParamsFromObject({
  from: wallet.address,
  suggestedParams,
  to: 'CJLKQWNTSQU64F4OBJSQK35THVI4KE4QIT3KEYB4CRBHQAIMO2CD6JWBCY',
  amount: 10000,
})

const bytes = encodeObj({ txn: transaction.get_obj_for_encoding() })

const res = await dfnsClient.wallets.generateSignature({
  walletId,
  body: {
    kind: 'Transaction',
    transaction: `0x${Buffer.from(bytes).toString('hex')}`,
  },
})
