The NodeJS example code from the recent Fuel tutorial blog post.

Getting_Started_with_Fuel_in_NodeJS.js

const { Wallet, utils, dbs } = require("fuel-core");

(async () => {
  
  // DB and Key Setup
  const db = new dbs.Level(); // persisting db
  const privateKey = (await db.get('key')) || utils.randomBytes(32);
  
  await db.put('key', privateKey);
  
  const signer = new utils.SigningKey(privateKey);
  
  console.log('My Fuel address is :', signer.address);
  
  // Wallet and Faucet of Fake Dai
  const wallet = new Wallet({ db, signer });
  
  // We allow the faucet to throw once the amount per IP limit is reached
  try { await wallet.faucet(); } catch (e) {}
  
  // Listen for Incoming Transaction Data
  await wallet.listen(async () => {
    console.log('Balance updates in transit',
      utils.formatEther(await wallet.balance(wallet.tokens.fakeDai)));
  });
  
  // Transfer of Fake Dai to Wallets
  await wallet.transfer(utils.parseEther('1.5'), wallet.tokens.fakeDai, wallet.address);
  
  // Fin.
  console.log('You transfered 1.5 Fake Dai to yourself, congrats!');
  
})();
