## Technology-Specific Security Patterns

### React/TypeScript Security Implementation
```typescript
// Command: /secure-auth
// Generates secure authentication component
import React, { useState, useContext, createContext } from 'react';
import { jwtDecode } from 'jwt-decode';

interface AuthContextType {
  user: User | null;
  login: (credentials: LoginCredentials) => Promise<void>;
  logout: () => void;
  isAuthenticated: boolean;
}

const AuthContext = createContext<AuthContextType | undefined>(undefined);

export const AuthProvider: React.FC<{ children: React.ReactNode }> = ({ children }) => {
  const [user, setUser] = useState<User | null>(null);
  const [isAuthenticated, setIsAuthenticated] = useState(false);

  const login = async (credentials: LoginCredentials) => {
    try {
      const response = await fetch('/api/auth/login', {
        method: 'POST',
        headers: {
          'Content-Type': 'application/json',
        },
        body: JSON.stringify(credentials),
        credentials: 'include', // Include httpOnly cookies
      });

      if (!response.ok) {
        throw new Error('Authentication failed');
      }

      const { user } = await response.json();
      setUser(user);
      setIsAuthenticated(true);
    } catch (error) {
      console.error('Login error:', error);
      throw error;
    }
  };

  const logout = async () => {
    try {
      await fetch('/api/auth/logout', {
        method: 'POST',
        credentials: 'include',
      });
    } catch (error) {
      console.error('Logout error:', error);
    } finally {
      setUser(null);
      setIsAuthenticated(false);
    }
  };

  return (
    <AuthContext.Provider value={{ user, login, logout, isAuthenticated }}>
      {children}
    </AuthContext.Provider>
  );
};

// Command: /input-validation
// Generates secure input validation
import DOMPurify from 'dompurify';
import { z } from 'zod';

const userInputSchema = z.object({
  email: z.string().email('Invalid email format'),
  password: z.string().min(8, 'Password must be at least 8 characters'),
  name: z.string().min(2, 'Name must be at least 2 characters').max(50, 'Name too long'),
});

export const validateAndSanitizeInput = (input: unknown) => {
  // Validate input structure
  const validatedInput = userInputSchema.parse(input);
  
  // Sanitize string inputs
  return {
    email: DOMPurify.sanitize(validatedInput.email),
    password: validatedInput.password, // Don't sanitize passwords
    name: DOMPurify.sanitize(validatedInput.name),
  };
};
```

### Node.js Security Implementation
```javascript
// Command: /secure-api
// Generates secure API endpoint with comprehensive security measures
const express = require('express');
const rateLimit = require('express-rate-limit');
const helmet = require('helmet');
const cors = require('cors');
const { body, validationResult } = require('express-validator');
const bcrypt = require('bcrypt');
const jwt = require('jsonwebtoken');

const app = express();

// Security middleware
app.use(helmet({
  contentSecurityPolicy: {
    directives: {
      defaultSrc: ["'self'"],
      scriptSrc: ["'self'"],
      styleSrc: ["'self'", "'unsafe-inline'"],
      imgSrc: ["'self'", "data:", "https:"],
    },
  },
}));

app.use(cors({
  origin: process.env.ALLOWED_ORIGINS?.split(',') || ['http://localhost:3000'],
  credentials: true,
}));

// Rate limiting
const limiter = rateLimit({
  windowMs: 15 * 60 * 1000, // 15 minutes
  max: 100, // limit each IP to 100 requests per windowMs
  message: 'Too many requests from this IP, please try again later.',
});

app.use('/api/', limiter);

// Input validation middleware
const validateUserInput = [
  body('email').isEmail().normalizeEmail(),
  body('password').isLength({ min: 8 }).matches(/^(?=.*[a-z])(?=.*[A-Z])(?=.*\d)(?=.*[@$!%*?&])[A-Za-z\d@$!%*?&]/),
  body('name').trim().isLength({ min: 2, max: 50 }).escape(),
];

// Authentication middleware
const authenticateToken = (req, res, next) => {
  const authHeader = req.headers['authorization'];
  const token = authHeader && authHeader.split(' ')[1];

  if (!token) {
    return res.status(401).json({ error: 'Access token required' });

      return res.status(403).json({ error: 'Invalid or expired token' });
    }
    req.user = user;

};

// Secure user creation endpoint
app.post('/api/users', validateUserInput, async (req, res) => {

    // Create user
    const user = await User.create({
      email,
      password: hashedPassword,
      name,
    });

    // Generate JWT
    const token = jwt.sign(
      { userId: user._id, email: user.email },
      process.env.JWT_SECRET,
      { expiresIn: '24h' }
    );

    // Set secure cookie
    res.cookie('token', token, {
      httpOnly: true,
      secure: process.env.NODE_ENV === 'production',
      sameSite: 'strict',
      maxAge: 24 * 60 * 60 * 1000, // 24 hours
    });

    res.status(201).json({
      message: 'User created successfully',
      user: {
        id: user._id,
        email: user.email,
        name: user.name,
      },
    });
  } catch (error) {
    console.error('User creation error:', error);
    res.status(500).json({ error: 'Internal server error' });
  }
});

// Command: /vulnerability-scan
// Generates vulnerability scanning configuration
const securityScanner = {
  scanDependencies: async () => {
    const { execSync } = require('child_process');
    try {
      const auditResult = execSync('npm audit --json', { encoding: 'utf8' });
      const audit = JSON.parse(auditResult);
      return {
        vulnerabilities: audit.vulnerabilities,
        summary: audit.metadata,
      };
    } catch (error) {
      console.error('Dependency scan failed:', error);
      return { error: 'Scan failed' };
    }
  },
