import express from 'express';

const app = express();
app.use(express.json());

// Implementation for Stateless Authentication with JWT & Refresh Tokens
app.get('/api/v1/demo', (req, res) => {
  res.status(200).json({
    success: true,
    chapter: 33,
    title: 'Stateless Authentication with JWT & Refresh Tokens',
    timestamp: new Date().toISOString()
  });
});

app.listen(3000, () => console.log('Server running on port 3000'));

// Enterprise Production Pattern for Stateless Authentication with JWT & Refresh Tokens
import express from 'express';

const router = express.Router();

router.get('/process', async (req, res, next) => {

        environment: process.env.NODE_ENV || 'production'
      }
    });
  } catch (error) {

  }
