**The AI Website Cloner Template explicitly excludes authentication flows and real-time backends from its cloning scope, requiring developers to implement mock APIs, environment variables, and client-side guards to simulate dynamic functionality in the generated Next.js application.**

The `ai-website-cloner-template` repository reconstructs static visual structures from target websites, but it cannot capture login systems, protected routes, or live databases. When working with cloned sites that require authentication or dynamic content, you must extend the generated codebase with architectural patterns that respect the template's static-first design while providing interactive functionality.

## Understanding the Architectural Boundaries

The template explicitly defines authentication and dynamic backends as **out of scope** across its platform-specific skill definitions. According to the OpenCode command specification in [[`.opencode/commands/clone-website.md`](https://github.com/JCodesMore/ai-website-cloner-template/blob/main/.opencode/commands/clone-website.md)](https://github.com/JCodesMore/ai-website-cloner-template/blob/master/.opencode/commands/clone-website.md#L22-L23), the cloning process ignores login flows, protected APIs, and live data interactions. This same limitation appears in the GitHub skill definition at [[`.github/skills/clone-website/SKILL.md`](https://github.com/JCodesMore/ai-website-cloner-template/blob/main/.github/skills/clone-website/SKILL.md)](https://github.com/JCodesMore/ai-website-cloner-template/blob/master/.github/skills/clone-website/SKILL.md#L22-L23).

Because the **parallel-builder workflow** expects complete static specifications rather than live connections, any dynamic functionality must be mocked or stubbed after the initial clone. The README's "[Customize (optional)](https://github.com/JCodesMore/ai-website-cloner-template/blob/master/README.md#L52-L53)" step provides the entry point for these modifications.

## Environment-Based Stubbing for Credentials

Store sensitive credentials and dummy tokens in environment variables to keep secrets out of source control while allowing the application to simulate authenticated states. This approach aligns with the template's clean separation of concerns, where utilities in `src/lib/` handle configuration while components remain pure.

Create a `.env` file from the template's `.env.example` and reference these values in your authentication utilities:

```typescript
// src/lib/auth.ts
export function getAuthToken(): string {
  // Uses the placeholder token from .env
  return process.env.NEXT_PUBLIC_DUMMY_TOKEN ?? 'dummy-token';
}

```

This pattern enables rapid prototyping when the real authentication service cannot be reached during development.

## Implementing Mock API Routes

Add Next.js API routes under `src/app/api/` to return static JSON that mimics the shape of original endpoints. This strategy satisfies component data requirements without requiring live backend connections during the parallel build process described in the README's "[How It Works](https://github.com/JCodesMore/ai-website-cloner-template/blob/master/README.md#L86-L95)" section.

Implement a mock user endpoint to simulate authentication checks:

```typescript
// src/app/api/user/route.ts
import { NextResponse } from 'next/server';
import type { User } from '@/types/user';

export async function GET() {
  const mockUser: User = {
    id: '123',
    name: 'Demo User',
    email: 'demo@example.com',
  };
  return NextResponse.json(mockUser);
}

```

Match the TypeScript interfaces in `src/types/` to the original API responses to maintain type safety across the cloned components.

## Protecting Routes with Authentication Guards

Wrap protected pages with higher-order components (HOCs) that check for mock tokens or cookies before rendering content. This pattern implements client-side route guards without modifying the core cloning pipeline.

Create a reusable authentication wrapper:

```typescript
// src/components/ui/RequireAuth.tsx
'use client';

import { useRouter } from 'next/navigation';
import { useEffect } from 'react';
import { getAuthToken } from '@/lib/auth';

export function RequireAuth({ children }: { children: React.ReactNode }) {
  const router = useRouter();

  useEffect(() => {
    if (!getAuthToken()) {
      router.replace('/mock-login');
    }
  }, [router]);

  return <>{children}</>;
}

```

Apply the guard to sensitive pages:

```typescript
// src/app/dashboard/page.tsx
import { RequireAuth } from '@/components/ui/RequireAuth';

export default function Dashboard() {
  return (
    <RequireAuth>
      <h1>Dashboard – Protected Content</h1>
    </RequireAuth>
  );
}

```

## Feature Flags and Conditional Rendering

Use environment variables to toggle between real authentication logic and mock implementations within the same codebase. This strategy allows the repository to support both development testing and production builds without code branching.

Configure the feature flag in `next.config.mjs`:

```javascript
// next.config.mjs
/** @type {import('next').NextConfig} */
const nextConfig = {
  env: {
    ENABLE_AUTH: process.env.NEXT_PUBLIC_ENABLE_AUTH ?? 'false',
  },
};

export default nextConfig;

```

Check this flag when initializing authentication providers or data fetching logic to conditionally load mock versus real implementations.

## Summary

- **Authentication is explicitly out of scope** in the AI Website Cloner Template, as documented in the OpenCode, GitHub, and Claude skill definitions.
- **Environment variables** provide secure credential stubbing for development environments without exposing secrets in the repository.
- **Mock API routes** in `src/app/api/` simulate backend responses while maintaining the TypeScript interfaces required by cloned components.
- **Authentication guards** using React HOCs protect client-side routes by checking tokens stored in environment variables or cookies.
- **Feature flags** enable conditional switching between mock and real authentication systems based on build-time environment variables.

## Frequently Asked Questions

### How does the AI Website Cloner Template handle login forms during the cloning process?

The template explicitly ignores authentication flows. According to the skill definitions in [[`.opencode/commands/clone-website.md`](https://github.com/JCodesMore/ai-website-cloner-template/blob/main/.opencode/commands/clone-website.md)](https://github.com/JCodesMore/ai-website-cloner-template/blob/master/.opencode/commands/clone-website.md#L22-L23), login forms, protected areas, and authentication states are considered out of scope. The cloning process captures the visual structure of login pages but not the underlying functionality, requiring developers to implement mock authentication afterward.

### Can I connect cloned sites to real databases or APIs?

While the template generates static Next.js applications, you can extend them to call real backends by implementing proxy routes or server-side fetching. However, you must add this functionality manually during the customization phase, as the parallel builder workflow expects static specifications in `docs/research/` rather than live connections. Use Next.js rewrites in `next.config.mjs` to forward API requests to production endpoints during development.

### Where should I store authentication types and interfaces in the cloned structure?

Store all TypeScript interfaces in `src/types/` to maintain the template's architectural separation of concerns. When creating mock API routes in `src/app/api/`, import these types to ensure the mocked JSON responses match the expected shapes used by components in `src/components/`. This consistency prevents type errors when switching between mock and real implementations.

### What is the recommended approach for handling dynamic user-specific content?

Implement **server-side authentication guards** using higher-order components that check for tokens in cookies or headers, combined with **mock API routes** that return user-specific placeholder data. For content that changes frequently, use Next.js data fetching with fallback to local JSON files stored in `src/lib/` or `public/`, allowing the UI to function offline while preserving the original site's visual structure.
