A beautiful CLI tool to quickly generate MVP project templates with modern frameworks and best practices

const express = require('express');
const cors = require('cors');
const helmet = require('helmet');
const apiRoutes = require('./routes/api');
const errorHandler = require('./middleware/errorHandler');

const app = express();
const port = process.env.PORT || 3000;

// Middleware
app.use(helmet()); // Security headers
app.use(cors()); // Enable CORS
app.use(express.json()); // Parse JSON bodies
app.use(express.urlencoded({ extended: true })); // Parse URL-encoded bodies

// Routes
app.get('/', (req, res) => {
  res.json({
    message: 'Welcome to Express API!',
    version: '1.0.0',
    endpoints: {
      health: '/health',
      api: '/api'
    }
  });
});

app.get('/health', (req, res) => {
  res.json({
    status: 'OK',
    timestamp: new Date().toISOString(),
    uptime: process.uptime()
  });
});

// API routes
app.use('/api', apiRoutes);

// Error handling middleware
app.use(errorHandler);

// 404 handler
app.use('*', (req, res) => {
  res.status(404).json({
    error: 'Route not found',
    path: req.originalUrl
  });
});

app.listen(port, () => {
  console.log(`🚀 Server is running on port ${port}`);
  console.log(`📍 Health check: http://localhost:${port}/health`);
  console.log(`🔗 API endpoint: http://localhost:${port}/api`);
});
