import { FlashnetClient } from '@flashnet/sdk';
import { SparkWallet } from '@buildonspark/spark-sdk';

// Initialize your Spark wallet
const { wallet } = await SparkWallet.initialize({
  mnemonicOrSeed: process.env.MNEMONIC,
  options: {
    network: "REGTEST", // or "MAINNET"
  },
});

// Create the Flashnet client
const client = new FlashnetClient(wallet);

// - Handle all signing and intent generation

​
Using the Spark Wallet

The Flashnet client can also be used as a regular Spark wallet: 
// Create a Lightning invoice using the client wallet
const invoice = await client.wallet.createLightningInvoice({
  amountSats: 1000000,
  memo: "Test invoice",
});

console.log(invoice);
