# Check for updates
npm outdated

# Update all packages
npm update

# Check for vulnerabilities
npm audit

Never commit sensitive data. Use .env.local:

# .env.local (never commit this file)
OPENAI_API_KEY=your_key_here
ANTHROPIC_API_KEY=your_key_here

Add to .gitignore:

.env*.local
.env.production

When integrating AI APIs:

// ✅ Good - Server-side only
// app/api/ai/route.ts
const apiKey = process.env.OPENAI_API_KEY;

// ❌ Bad - Never expose keys client-side
// const apiKey = "sk-..."; // NEVER DO THIS

Always validate user input:

// Validate and sanitize
const sanitized = input.trim().slice(0, 1000);
if (!sanitized) throw new Error("Invalid input");

Add to next.config.mjs:

const nextConfig = {
  async headers() {
    return [
      {
        source: '/:path*',
        headers: [
          {
            key: 'X-Frame-Options',
            value: 'DENY',
          },
          {
            key: 'X-Content-Type-Options',
            value: 'nosniff',
          },
          {
            key: 'Referrer-Policy',
            value: 'origin-when-cross-origin',
          },
        ],
      },
    ];
  },
};
