## Example: Before vs After

### Before (without cursor-rules-awesome)
```javascript
app.post('/login', (req, res) => {
  const user = db.findUser(req.body.email);
  if (user && user.password === req.body.password) {
    res.json({ token: generateToken(user) });
  } else {
    res.status(401).send('Invalid credentials');
  }
});
```

**Issues:**
- No input validation
- Plain text password comparison
- No rate limiting
- No audit logging
- Multiple security vulnerabilities

### After (with cursor-rules-awesome)
```javascript
app.post('/login', [
  rateLimiter({ max: 5, windowMs: 15 * 60 * 1000 }),
  validateRequest(loginSchema),
  sanitizeInput
], async (req, res) => {
  try {
    const { email, password } = req.body;
    
    const sanitizedEmail = validator.normalizeEmail(email);
    const user = await db.findUser(sanitizedEmail);
    
    if (!user) {
      await auditLog.warn('Login attempt for non-existent user', { email: sanitizedEmail });
      return res.status(401).json({ error: 'Invalid credentials' });
    }
    
    const isValid = await bcrypt.compare(password, user.passwordHash);
    if (!isValid) {
      await auditLog.warn('Invalid password attempt', { userId: user.id });
      await loginAttempts.increment(user.id);
      
      if (await loginAttempts.get(user.id) >= 5) {
        await user.lock();
        await auditLog.error('Account locked', { userId: user.id });
        return res.status(423).json({ error: 'Account locked' });
      }
      
      return res.status(401).json({ error: 'Invalid credentials' });
    }
    
    const accessToken = jwt.sign(
      { userId: user.id, role: user.role },
      process.env.JWT_SECRET,
      { expiresIn: '15m', algorithm: 'RS256' }
    );
    
    const refreshToken = generateRefreshToken(user.id);
    
    await auditLog.info('Successful login', { 
      userId: user.id, 
      ip: req.ip,
      userAgent: req.headers['user-agent']
    });
    
    await loginAttempts.reset(user.id);
    
    res.json({
      accessToken,
      refreshToken,
      expiresIn: 900,
      tokenType: 'Bearer'
    });
    
  } catch (error) {
    logger.error('Login error', { error: error.message, stack: error.stack });
    res.status(500).json({ error: 'Internal server error' });
  }
});
```

**Improvements:**
- Input validation & sanitization
- Secure bcrypt password hashing
- Rate limiting (5 attempts / 15 min)
- Account lockout protection
- Comprehensive audit logging
- JWT with RS256 algorithm
- Refresh token support
- Proper error handling
