    message: 'Hello World! 🌍',
    framework: 'Qwe',
    timestamp: new Date().toISOString()
  });
});

app.post('/users', (qwe) => {
  // ✅ Built-in validation
  const validation = qwe.validate.object({
    name: qwe.validate.string().min(2),
    email: qwe.validate.string().email()
  });

  const result = validation.validate(qwe.body);
  if (!result.success) {
    return qwe.badRequest('Validation failed', result.errors);
  }

  // ✨ Create user with generated ID
  const user = {
    id: qwe.generateId(),
    ...result.data,
    createdAt: new Date().toISOString()
  };

  qwe.created(user, 'User created successfully 🎉');
});

// 🚀 Start the server
app.listen(3000, () => {
  console.log('🎆 Server running on http://localhost:3000');
});

🔑 Key Concepts

🧠 Unified Context Pattern

| Express.js 🐌 | Qwe Framework ⚡ | |:---:|:---:| | (req, res) => {} | (qwe) => {} | | 2 objects to manage | 1 unified context | | Scattered functionality | Everything in one place |

// 🐌 Express Pattern - Multiple objects
app.get('/users', (req, res) => {
  const body = req.body;
  const query = req.query;
  const params = req.params;
  
  res.status(200).json({ 
    users: [],
    message: 'Users retrieved'
  });
});

// ⚡ Qwe Pattern - Single unified context
app.get('/users', (qwe) => {
  const { body, query, params } = qwe;  // Everything in one place!
  
  qwe.success({ users: [] }, 'Users retrieved'); // Template response!
});

🎯 Template Responses

Standardized, consistent API responses with built-in formatting:

app.post('/users', (qwe) => {
  // ✅ Success responses
  qwe.success(data, 'Success message');           // 200
  qwe.created(data, 'Created successfully');      // 201
  
  // ❌ Error responses
  qwe.badRequest('Invalid input');                // 400
  qwe.unauthorized('Access denied');              // 401
  qwe.forbidden('Permission denied');             // 403
  qwe.notFound('Resource not found');             // 404
  qwe.conflict('Resource already exists');        // 409
  qwe.unprocessableEntity('Validation failed');   // 422
  qwe.internalServerError('Something went wrong'); // 500
});

All responses follow this consistent format:

{
  "success": true,
  "statusCode": 200,
  "message": "Success message",
  "data": { "id": "123", "name": "John" },
  "timestamp": "2024-01-15T10:30:00.000Z",
  "requestId": "req_7f8a9b2c3d4e5f6g"
}

🛠 Built-in Features

Validation

Zod-like validation engine:

app.post('/users', (qwe) => {
  const schema = qwe.validate.object({
    name: qwe.validate.string().min(2).max(50),
    email: qwe.validate.string().email(),
    age: qwe.validate.number().min(18).optional(),
    tags: qwe.validate.array(qwe.validate.string())
  });

  const result = schema.validate(qwe.body);
  if (!result.success) {
    return qwe.unprocessableEntity('Validation failed', result.errors);
  }
  
  // Use validated data
  const userData = result.data;
});

Authentication & Security

Built-in JWT and hashing:

app.post('/auth/login', async (qwe) => {
  const { email, password } = qwe.body;
  
  const user = await findUserByEmail(email);
  const isValid = await qwe.hash.compare(password, user.password);
  
  if (isValid) {
    const token = qwe.jwt.sign(
      { userId: user.id, email },
      'your-secret-key',
      { expiresIn: '24h' }
    );
    
    qwe.success({ token, user });
  } else {
    qwe.unauthorized('Invalid credentials');
  }
});

// Password hashing
const hashedPassword = await qwe.hash.bcrypt('password123');

JWT Middleware

Qwe provides powerful JWT middleware for protecting routes:

Global Protection

import { createApp, jwtAuth } from 'qwe-js';

const app = createApp();

// Protect all routes globally
app.plugin(jwtAuth({ secret: 'your-jwt-secret' }));

// All routes after this middleware require JWT
app.get('/protected', (qwe) => {
  const user = qwe.user; // Access authenticated user
  qwe.success({ message: 'Protected data', user });
});

Route-Specific Protection

import { jwtMiddleware, requireRoles, requirePermissions } from 'qwe-js';

// Create middleware instance
const authMiddleware = jwtMiddleware({ secret: 'your-jwt-secret' });

// Protect individual routes
app.get('/profile', authMiddleware, (qwe) => {
  qwe.success({ user: qwe.user });
});

// Role-based protection
app.get('/admin', authMiddleware, requireRoles('admin'), (qwe) => {
  qwe.success({ message: 'Admin only content' });
});

// Permission-based protection
app.post('/write-data', 
  authMiddleware, 
  requirePermissions('write', 'admin'), 
  (qwe) => {
    qwe.success({ message: 'Data written successfully' });
  }
);

// Multiple roles
app.get('/staff', authMiddleware, requireRoles('admin', 'moderator'), (qwe) => {
  qwe.success({ message: 'Staff area' });
});

Optional Authentication

import { optionalAuth } from 'qwe-js';

// Works with or without authentication
app.get('/public', optionalAuth({ secret: 'your-jwt-secret' }), (qwe) => {
  const user = qwe.user; // null if not authenticated
  
  qwe.success({
    message: user ? 'Hello authenticated user!' : 'Hello guest!',
    authenticated: !!user
  });
});

Advanced JWT Configuration

const authMiddleware = jwtMiddleware({
  secret: 'your-jwt-secret',
  
  // Custom token extraction
  getToken: (qwe) => {
    // Extract from custom header
    return qwe.headers['x-auth-token'] || 
           qwe.query.token || 
           qwe.cookies.token;
  },
  
  // Token revocation check
  isRevoked: async (qwe, payload) => {
    return await checkTokenRevocation(payload.jti);
  },
  
  // Custom error handling
  onError: (qwe, error) => {
    console.error('JWT Error:', error.message);
  },
  
  // Audience validation
  audience: 'your-api',
  
  // Issuer validation
  issuer: 'your-app',
  
  // Custom user property name
  requestProperty: 'currentUser' // Access via qwe.currentUser
});

Ownership-Based Access Control

import { requireOwnershipOrRole } from 'qwe-js';

// Users can only access their own resources (or admins can access all)
app.get('/users/:id/profile', 
  authMiddleware,
  requireOwnershipOrRole(
    (qwe) => qwe.params.id, // Get resource owner ID
    ['admin', 'superuser']  // Admin roles that can access all
  ),
  (qwe) => {
    qwe.success({ profile: getUserProfile(qwe.params.id) });
  }
);

JWT Token Structure

When using JWT middleware, include role and permission information in your tokens:

app.post('/auth/login', async (qwe) => {
  // ... authentication logic ...
  
  const token = qwe.jwt.sign({
    userId: user.id,
    email: user.email,
    role: user.role,           // For role-based access
    permissions: user.permissions, // For permission-based access
    // ... other claims
  }, 'your-secret-key', {
    expiresIn: '24h',
    issuer: 'your-app',
    audience: 'your-api'
  });
  
  qwe.success({ token, user });
});

File Uploads

Multer-like file handling:

app.post('/upload', (qwe) => {
  const files = qwe.files; // Array of uploaded files
  
  files.forEach(file => {
    console.log(file.originalName, file.size, file.mimeType);
    // Save file.buffer to storage
  });
  
  qwe.success({ uploaded: files.length });
});

Database & ORM

Built-in ORM with multi-database support:

// SQL Database (PostgreSQL, MySQL, SQLite)
const orm = createORM();
await orm.connect({
  dialect: 'postgresql',
  host: 'localhost',
  port: 5432,
  database: 'myapp',
  username: 'user',
  password: 'password'
});

// MongoDB
await orm.connect({
  dialect: 'mongodb',
  connectionString: 'mongodb://localhost:27017/myapp'
});

// Define models (works with all databases)
const User = orm.model('User', {
  id: { type: 'string', primaryKey: true },
  name: { type: 'string', required: true },
  email: { type: 'string', required: true, unique: true },
  profile: { type: 'json', default: {} }
});

app.post('/users', async (qwe) => {
  const user = await User.create(qwe.body);
  qwe.created(user, 'User created successfully');
});

app.get('/users', async (qwe) => {
  const users = await User.findMany({
    where: { active: true },
    orderBy: { createdAt: 'desc' },
    take: 10
  });
  qwe.success(users);
});

🔌 Plugin System

Built-in Plugins

import { createApp, cors, logger, rateLimiter, compression, security, jwtAuth } from 'qwe-js';

const app = createApp();

// CORS
app.plugin(cors({
  origin: 'https://yourdomain.com',
  credentials: true
}));

// Logging
app.plugin(logger({ format: 'combined' }));

// Rate limiting
app.plugin(rateLimiter({
  max: 100,
  windowMs: 60000
}));

// Compression
app.plugin(compression());

// Security headers
app.plugin(security({
  contentSecurityPolicy: "default-src 'self'",
  xFrameOptions: 'DENY'
}));

// JWT Authentication (global)
app.plugin(jwtAuth({
  secret: 'your-jwt-secret',
  credentialsRequired: true
}));

### Custom Plugins

```typescript
const customPlugin = {
  name: 'my-plugin',
  install: (app) => {
    app.use(async (qwe, next) => {
      qwe.header('X-Custom-Header', 'value');
      await next();
    });
  }
};

app.plugin(customPlugin);

# Show help
qwe --help

Modular vs Traditional Structure

Traditional Structure (qwe generate module user):

• Creates: src/controllers/user.controller.ts
• Creates: src/services/user.service.ts
• Creates: src/routes/user.router.ts

Modular Structure (qwe generate modular-module user) ✨:

• Creates: src/modules/user/user.controller.ts
• Creates: src/modules/user/user.service.ts
• Creates: src/modules/user/user.routes.ts
• Creates: src/modules/user/user.models.ts

🎆 New! The modular structure keeps related files together and includes models with TypeScript interfaces and DTOs.

Generated Module Structure

With the new CLI generator, you can create modular structures:

# Generate modular structure
qwe generate modular-module auth

This creates a self-contained module:

src/modules/auth/
├── auth.controller.ts  # CRUD operations (getAll, getById, create, update, delete)
├── auth.service.ts     # Business logic with data management
├── auth.routes.ts      # Route setup function with REST endpoints
└── auth.models.ts      # TypeScript interfaces and DTOs

Module Benefits

• Self-contained: Each module has its own controller, service, routes, and models
• Type-safe: Full TypeScript support with interfaces and DTOs
• CRUD ready: Generated with complete CRUD operations
• Framework integrated: Uses Qwe's unified context pattern
• Easy to maintain: Clear separation of concerns within each module
