Popup Studio AI Bkit Gemini Phase 6 UI Integration

Phase 6: UI Integration

Connect your frontend to the backend

Key Tasks

1. API Client Setup

// lib/api/client.ts
const API_BASE = process.env.NEXT_PUBLIC_API_URL;

export async function fetchAPI<T>(
  endpoint: string,
  options?: RequestInit
): Promise<T> {
  const res = await fetch(`${API_BASE}${endpoint}`, {
    headers: {
      'Content-Type': 'application/json',
      ...options?.headers,
    },
    ...options,
  });

  if (!res.ok) {
    throw new Error(`API Error: ${res.status}`);
  }

  return res.json();
}

2. Data Fetching

// Server Component
async function UserList() {
  const users = await fetchAPI<User[]>('/api/users');

  return (
    <ul>
      {users.map(user => (
        <li key={user.id}>{user.name}</li>
      ))}
    </ul>
  );
}

3. Form Handling

// Client Component with Server Action
'use client';

export function LoginForm() {
  const [pending, startTransition] = useTransition();

  async function handleSubmit(formData: FormData) {
    startTransition(async () => {
      await loginAction(formData);
    });
  }

  return (
    <form action={handleSubmit}>
      <input name="email" type="email" required />
      <input name="password" type="password" required />
      <button disabled={pending}>
        {pending ? 'Loading...' : 'Login'}
      </button>
    </form>
  );
}

4. State Management

• Server State: React Query / SWR
• Client State: Zustand / Jotai
• Form State: React Hook Form

Integration Checklist

• API client configured
• Authentication flow working
• Error boundaries added
• Loading states implemented
