const app = express();

// Session middleware for storing tokens
app.use(session({
  secret: 'your-secret-key',
  resave: false,
  saveUninitialized: false
}));

// Initialize Xero Client
const xero = new XeroClient({
  clientId: 'YOUR_CLIENT_ID',
  clientSecret: 'YOUR_CLIENT_SECRET',
  redirectUri: 'http://localhost:3000/callback',
  grantType: 'authorization_code'
});

// Route to initiate OAuth2 flow
app.get('/login', async (req, res) => {
  await xero.login();
  const consentUrl = xero.buildConsentUrl();
  res.redirect(consentUrl);
});

// Callback route after user grants consent
app.get('/callback', async (req, res) => {
  await xero.exchangeCodeForToken(req.query.code);
  // Store tokens in session or database
  req.session.tokenSet = xero.readTokenSet();
  res.redirect('/invoices');
});

// Example route to fetch invoices
app.get('/invoices', async (req, res) => {
  if (!req.session.tokenSet) {
    return res.redirect('/login');
  }
  xero.setTokenSet(req.session.tokenSet);
