⚙️ Basic Setup (5 minutes)

1. Environment Configuration

Create .env.local with your Auth0 credentials:

# Required - Auth0 Application Settings
# 🔐 統一認証: auth.gftd.ai ドメインとCLIENT_IDは SDK にデフォルト組み込み済み
# カスタム設定が必要な場合のみ環境変数を設定してください
AUTH0_DOMAIN=auth.gftd.ai                                    # SDKデフォルト: auth.gftd.ai
AUTH0_CLIENT_ID=k0ziPQ6IkDxE1AUSvzx5PwXtnf4y81x0            # SDKデフォルト: k0ziPQ6IkDxE1AUSvzx5PwXtnf4y81x0
AUTH0_CLIENT_SECRET=your-client-secret                       # 必須: 個別設定
AUTH0_SECRET=your-32-char-secret-key                         # 必須: セッション暗号化キー（32文字以上）
AUTH0_BASE_URL=http://localhost:3000                         # 必須: アプリケーションのベースURL

# Optional - Advanced Features

# AUTH0_SCOPE=openid profile email read:users              # SDKデフォルト: openid profile email

2. Middleware Setup (Choose One)

Option A: Simple Setup (Recommended)

// middleware.ts
import { withMiddlewareAuthRequired } from '@gftdcojp/gftd-auth/nextjs-auth0';

export default withMiddlewareAuthRequired();

export const config = {
  matcher: [
    '/((?!api/auth|_next/static|_next/image|favicon.ico).*)',
  ],
};

Option B: Direct Middleware

// middleware.ts
import { auth0Middleware } from '@gftdcojp/gftd-auth/nextjs-auth0';

export default auth0Middleware;

export const config = {
  matcher: [
    '/((?!api/auth|_next/static|_next/image|favicon.ico).*)',
  ],
};

3. App Setup

App Router (app/layout.tsx)

import { UserProvider } from '@gftdcojp/gftd-auth/client';

export default function RootLayout({
  children,
}: {
  children: React.ReactNode;
}) {
  return (
    <html lang="en">
      <body>
        <UserProvider>
          {children}
        </UserProvider>
      </body>
    </html>
  );
}

Pages Router (pages/_app.tsx)

import { UserProvider } from '@gftdcojp/gftd-auth/client';
import type { AppProps } from 'next/app';

export default function App({ Component, pageProps }: AppProps) {
  return (
    <UserProvider>
      <Component {...pageProps} />
    </UserProvider>
  );
}

4. Route Handlers Setup (Next.js App Router)

⚠️ 重要: Next.js 14 App RouterのRoute HandlerではNextResponse.next()が使用できません。新しいRoute Handler専用APIを使用してください。

Option A: 統合Route Handler (推奨)

// app/api/auth/[...auth0]/route.ts
import { handleAuth } from '@gftdcojp/gftd-auth/nextjs-auth0';
import { NextRequest } from 'next/server';

export async function GET(request: NextRequest, { params }: { params: { auth0: string[] } }) {
  return handleAuth(request, params.auth0[0]);
}

export async function POST(request: NextRequest, { params }: { params: { auth0: string[] } }) {
  return handleAuth(request, params.auth0[0]);
}

Option B: 個別Route Handler

// app/api/auth/login/route.ts
import { handleAuthLogin } from '@gftdcojp/gftd-auth/nextjs-auth0';
export async function GET(request: NextRequest) {
  return handleAuthLogin(request);
}

// app/api/auth/logout/route.ts
import { handleAuthLogout } from '@gftdcojp/gftd-auth/nextjs-auth0';
export async function GET(request: NextRequest) {
  return handleAuthLogout(request);
}

// app/api/auth/callback/route.ts
import { handleAuthCallback } from '@gftdcojp/gftd-auth/nextjs-auth0';
export async function GET(request: NextRequest) {
  return handleAuthCallback(request);
}

// app/api/auth/me/route.ts
import { handleAuthMe } from '@gftdcojp/gftd-auth/nextjs-auth0';
export async function GET(request: NextRequest) {
  return handleAuthMe(request);
}

5. 🔧 Middleware vs Route Handler の使い分け

| 用途 | API | ファイル場所 | 説明 | |------|-----|--------------|------| | Middleware | auth0Middleware | middleware.ts | ページアクセス時の認証チェック | | Route Handler | handleAuth | /api/auth/*/route.ts | 認証エンドポイントの処理 |

✅ Middleware（middleware.ts）

// middleware.ts - ページの認証保護
import { auth0Middleware } from '@gftdcojp/gftd-orm';

export default auth0Middleware;

export const config = {
  matcher: [
    '/((?!api/auth|_next/static|_next/image|favicon.ico).*)',
  ],
};

✅ Route Handler（/api/auth/*/route.ts）

// app/api/auth/[...auth0]/route.ts - 認証エンドポイント処理
import { handleAuth } from '@gftdcojp/gftd-orm';

export async function GET(request: NextRequest, { params }: { params: { auth0: string[] } }) {
  return handleAuth(request, params.auth0[0]);
}

6. ⚠️ よくある問題と解決策

❌ Next.js App Routerでこれは動作しません:

// ❌ Route HandlerでNextResponse.next()を使用
export async function GET(request: NextRequest) {
  return auth0Client.middleware(request); // Error: NextResponse.next() は使用不可
}

✅ 正しい実装:

// ✅ Route Handler専用APIを使用
export async function GET(request: NextRequest) {
  return handleAuthCallback(request); // 完結したResponseを返す
}

🎯 Common Use Cases

🔐 Authentication Components

Login/Logout Button

// components/AuthButton.tsx
import { useUser, useLogout } from '@gftdcojp/gftd-auth/client';

export default function AuthButton() {
  const { user, isLoading } = useUser();
  const logout = useLogout();

  if (isLoading) return <div>Loading...</div>;

  if (user) {
    return (
      <div className="flex items-center gap-4">
        <img src={user.user_metadata?.picture} alt="Profile" className="w-8 h-8 rounded-full" />
        <span>Welcome, {user.user_metadata?.name}!</span>
        <button 
          onClick={() => logout()}
          className="btn btn-ghost"
        >
          Logout
        </button>
      </div>
    );
  }

  return (

  const { accessToken } = await getAccessToken() || {};
  
  return Response.json({
    user: session?.user,
    tokenInfo: {
      hasToken: !!accessToken,
      expiresAt: session?.expiresAt,
    },
    message: 'This is a protected API route',
  });
});

Server-side Data Fetching

// app/admin/page.tsx (Server Component)
import { getSession } from '@gftdcojp/gftd-orm/nextjs-auth0';
import { redirect } from 'next/navigation';

export default async function AdminPage() {
  const session = await getSession();
  
  if (!session) {
    redirect('/auth/login');
  }

  // Check admin role
  const userRoles = session.user.metadata?.roles || [];
  if (!userRoles.includes('admin')) {
    redirect('/unauthorized');
  }

  return (
    <div>
      <h1>Admin Dashboard</h1>
      <p>Welcome, {session.user.name}</p>
    </div>
  );
}

📚 Advanced Features

🏢 Organizations (B2B Multi-tenant)

Perfect for B2B SaaS applications with multiple tenants.

Organization Management API

import { Auth0Integration } from '@gftdcojp/gftd-orm/auth0-integration';

const auth0 = Auth0Integration.getInstance();

// Create organization
const org = await auth0.createOrganization({
  name: 'acme-corp',
  display_name: 'ACME Corporation',
  branding: {
    logo_url: 'https://example.com/logo.png',
    colors: {
      primary: '#FF6B6B',
      page_background: '#F8F9FA',
    },
  },
  metadata: {
    tier: 'enterprise',
    max_users: 1000,
  },
});

// Invite members with roles
const invitation = await auth0.createOrganizationInvitation(org.id, {
  inviter: { name: 'Admin' },
  invitee: { email: '[email protected]' },
  client_id: process.env.AUTH0_CLIENT_ID!,
  roles: ['org:admin', 'billing:manager'],
  send_invitation_email: true,
  ttl_sec: 86400, // 24 hours
});

// Manage members and roles
await auth0.addOrganizationMembers(org.id, ['auth0|user123']);
await auth0.addOrganizationMemberRoles(org.id, 'auth0|user123', ['org:admin']);

Organization-scoped Authentication

// components/OrgSelector.tsx
import { useRouter } from 'next/navigation';

export function OrgSelector({ organizations }: { organizations: Organization[] }) {
  const router = useRouter();

  const handleOrgLogin = (orgId: string) => {
    // Redirect to organization-specific login
    router.push(`/auth/login?organization=${orgId}&returnTo=/dashboard`);
  };

  return (
    <div className="grid gap-4">
      {organizations.map((org) => (
        <div key={org.id} className="border rounded-lg p-4">
          <img src={org.branding?.logo_url} alt={org.display_name} className="h-12" />
          <h3>{org.display_name}</h3>
          <button 
            onClick={() => handleOrgLogin(org.id)}
            className="btn btn-primary"
          >
            Sign in to {org.display_name}
          </button>
        </div>
      ))}
    </div>
  );
}

🗄️ Custom Session Store

Enterprise-grade session persistence with multiple storage backends.

Database Session Store (Recommended for Production)

// lib/sessionStore.ts
import { SessionStoreFactory } from '@gftdcojp/gftd-orm/auth0-session-store';
import mysql from 'mysql2/promise';

// Create database connection
const db = await mysql.createConnection({
  host: process.env.DB_HOST,
  user: process.env.DB_USER,
  password: process.env.DB_PASSWORD,
  database: process.env.DB_NAME,
});

// Create session store
const sessionStore = SessionStoreFactory.createDatabaseStore(db, {
  tableName: 'auth0_sessions',
  schemaName: 'auth',
  cleanupInterval: 3600, // Clean expired sessions every hour
});

// Initialize schema (run once)
await sessionStore.createSchema();

// Health check
const health = await sessionStore.health();
console.log(health); // { status: 'ok', message: '1,234 active sessions' }

Redis Session Store (High Performance)

import { SessionStoreFactory } from '@gftdcojp/gftd-orm/auth0-session-store';
import Redis from 'ioredis';

const redis = new Redis({
  host: process.env.REDIS_HOST,
  port: parseInt(process.env.REDIS_PORT || '6379'),
  password: process.env.REDIS_PASSWORD,
  db: 0,
});

const sessionStore = SessionStoreFactory.createRedisStore(redis, {
  keyPrefix: 'auth0:session:',
  defaultTtl: 7 * 24 * 60 * 60, // 7 days
  enableCompression: true,
});

// Usage in middleware
const client = new NextJsAuth0Client({
  sessionStore,
  // ... other config
});

Memory Store (Development Only)

import { SessionStoreFactory } from '@gftdcojp/gftd-orm/auth0-session-store';

const sessionStore = SessionStoreFactory.createMemoryStore({
  maxSessions: 10000,
  cleanupIntervalMs: 300000, // 5 minutes
});

🌐 Edge Runtime Support

Deploy authentication to the edge for ultra-low latency worldwide.

Vercel Edge Functions

// middleware.ts
export { auth0Middleware as default } from '@gftdcojp/gftd-orm/nextjs-auth0-edge';

export const config = {
  matcher: [
    '/((?!api/auth|_next/static|_next/image|favicon.ico).*)',
  ],
  runtime: 'edge',
};

Cloudflare Workers

// worker.ts
import { createEdgeAuth0Client } from '@gftdcojp/gftd-orm/nextjs-auth0-edge';

const client = createEdgeAuth0Client({
  domain: process.env.AUTH0_DOMAIN!,
  clientId: process.env.AUTH0_CLIENT_ID!,
  clientSecret: process.env.AUTH0_CLIENT_SECRET!,
  appBaseUrl: process.env.AUTH0_BASE_URL!,
  secret: process.env.AUTH0_SECRET!,
});

export default {
  async fetch(request: Request): Promise<Response> {
    return await client.handleRequest(request);
  },
};

Deno Deploy

// main.ts
import { createEdgeAuth0Client } from 'npm:@gftdcojp/gftd-orm/nextjs-auth0-edge';

const client = createEdgeAuth0Client({
  domain: Deno.env.get('AUTH0_DOMAIN')!,
  clientId: Deno.env.get('AUTH0_CLIENT_ID')!,
  clientSecret: Deno.env.get('AUTH0_CLIENT_SECRET')!,
  appBaseUrl: Deno.env.get('AUTH0_BASE_URL')!,
  secret: Deno.env.get('AUTH0_SECRET')!,
});

Deno.serve(client.handleRequest);

🔄 Back-Channel Logout

Enterprise-grade session management with automatic session invalidation.

Setup in Auth0 Dashboard

1. Go to your Auth0 Application settings
2. Add Back-Channel Logout URL: https://your-app.com/auth/backchannel-logout
3. Enable "Back-Channel Logout" in Advanced Settings

Automatic Handling (Zero Config)

// middleware.ts - Sessions are automatically invalidated
import { auth0Middleware } from '@gftdcojp/gftd-orm/nextjs-auth0';

export default auth0Middleware; // Back-channel logout is built-in

export const config = {
  matcher: [
    '/((?!api/auth|_next/static|_next/image|favicon.ico).*)',
  ],
};

Manual Session Management

// app/api/admin/invalidate-sessions/route.ts
import { Auth0Integration } from '@gftdcojp/gftd-orm/auth0-integration';

export async function POST(request: Request) {
  const { userId } = await request.json();
  
  const auth0 = Auth0Integration.getInstance();
  
  // Invalidate all sessions for a user
  await auth0.invalidateUserSessions(userId);
  
  return Response.json({ success: true });
}

📊 Real-time Data Platform

Powerful stream processing with ksqlDB and real-time TypeScript types.

Automatic Type Generation

# Generate TypeScript types from ksqlDB schemas
npx gftd-orm generate-types --table USERS_TABLE --output ./types
npx gftd-orm generate-types --table ORDERS_STREAM --output ./types

# Generate all types
npx gftd-orm generate-all --output ./types --watch

Real-time Data Streaming

import { createClient } from '@gftdcojp/gftd-orm';

// Initialize client with ksqlDB and Schema Registry
const client = createClient({
  url: 'http://localhost:8088',
  database: {
    ksql: { 
      url: 'http://localhost:8088',
      apiKey: process.env.KSQL_API_KEY,
    },
    schemaRegistry: { 
      url: 'http://localhost:8081',
      apiKey: process.env.SCHEMA_REGISTRY_API_KEY,
    },
  },
  realtime: { 
    url: 'ws://localhost:8088',
    apiKey: process.env.REALTIME_API_KEY,
  },
});

// Type-safe real-time subscriptions
const userActivityChannel = client.channel<UserActivity>('user_activity_stream');

userActivityChannel.on('insert', (payload) => {
  console.log('New user activity:', payload); // Fully typed
});

userActivityChannel.on('update', (payload) => {
  console.log('Updated activity:', payload);
});

// React Hook integration
import { useRealtimeSubscription } from '@gftdcojp/gftd-orm/hooks';

function ActivityFeed() {
  const { data, isLoading, error } = useRealtimeSubscription(
    client,
    'user_activity_stream'
  );

  if (isLoading) return <div>Loading...</div>;
  if (error) return <div>Error: {error.message}</div>;

  return (
    <div>
      {data.map((activity) => (
        <div key={activity.id}>{activity.description}</div>
      ))}
    </div>
  );
}

Stream Processing Queries

// Execute ksqlDB queries with type safety
import { executeQuery } from '@gftdcojp/gftd-orm';

const result = await executeQuery(`
  SELECT 
    user_id,
    COUNT(*) as activity_count,
    WINDOWSTART() as window_start
  FROM user_activity_stream
  WINDOW TUMBLING (SIZE 1 HOUR)
  GROUP BY user_id
  EMIT CHANGES;
`);

// Real-time analytics dashboard
const analytics = client.channel('user_analytics');
analytics.on('update', (metrics) => {
  updateDashboard(metrics); // Real-time dashboard updates
});

import { 
  UserProvider,           // Context provider
  AuthenticatedLayout,    // Layout with auth check
} from '@gftdcojp/gftd-orm/client';

// Protection HOCs
import { 
  withPageAuthRequired,   // Protect pages
  withApiAuthRequired,    // Protect API routes
} from '@gftdcojp/gftd-orm/client';

6. Migration Example

Before (nextjs-auth0):

// app/layout.tsx
import { UserProvider } from '@auth0/nextjs-auth0/client';

// components/Profile.tsx
import { useUser } from '@auth0/nextjs-auth0/client';

// app/dashboard/page.tsx
import { withPageAuthRequired } from '@auth0/nextjs-auth0/client';

// app/api/protected/route.ts
import { withApiAuthRequired, getSession } from '@auth0/nextjs-auth0';

After (GFTD ORM):

// app/layout.tsx
import { UserProvider } from '@gftdcojp/gftd-orm/client';

// components/Profile.tsx
import { useUser } from '@gftdcojp/gftd-orm/client';

// app/dashboard/page.tsx
import { withPageAuthRequired } from '@gftdcojp/gftd-orm/client';

// app/api/protected/route.ts
import { withApiAuthRequired } from '@gftdcojp/gftd-orm/client';
import { getSession } from '@gftdcojp/gftd-orm/nextjs-auth0';

7. Environment Variables (No Changes Required)

Your existing Auth0 environment variables work as-is:

AUTH0_DOMAIN=your-domain.auth0.com
AUTH0_CLIENT_ID=your-client-id
AUTH0_CLIENT_SECRET=your-client-secret
AUTH0_SECRET=your-32-char-secret
AUTH0_BASE_URL=http://localhost:3000

🛠️ Troubleshooting

❌ Cannot find module '@gftdcojp/gftd-orm/client'

✅ Solution: This error occurs when the package is not yet published. Use our fallback implementation:

// Use the working example with fallback implementation
import { useGftdOrmExample } from './examples/gftd-orm-example';

// This automatically detects if the package is available and falls back to mock implementation
const { client, isConnected, error } = useGftdOrmExample(config);

Once the package is published, use correct import paths:

• Client-side: @gftdcojp/gftd-orm/client
• Server-side: @gftdcojp/gftd-orm/nextjs-auth0
• Edge Runtime: @gftdcojp/gftd-orm/nextjs-auth0-edge

❌ 'UserProvider' has no exported member

✅ Solution: Import from client path:

// ✅ Correct
import { UserProvider } from '@gftdcojp/gftd-orm/client';

// ❌ Wrong
import { UserProvider } from '@gftdcojp/gftd-orm';

❌ Middleware not working on Edge Runtime

✅ Solution: Use Edge-specific import:

// ✅ For Edge Runtime
import { auth0Middleware } from '@gftdcojp/gftd-orm/nextjs-auth0-edge';

// ✅ For Node.js Runtime
import { auth0Middleware } from '@gftdcojp/gftd-orm/nextjs-auth0';

❌ Session not persisting

✅ Solution: Check AUTH0_SECRET length:

# ❌ Too short
AUTH0_SECRET=short

# ✅ Minimum 32 characters
AUTH0_SECRET=your-32-character-secret-key-here

❌ React Hydration Error (Server/Client Mismatch)

✅ Solution: Use isMounted pattern to prevent SSR/CSR mismatch:

'use client';
import { useState, useEffect } from 'react';
import { useUser } from '@gftdcojp/gftd-orm/client';

export function AuthComponent() {
  const { user, isLoading } = useUser();
  const [isMounted, setIsMounted] = useState(false);

  useEffect(() => {
    setIsMounted(true);
  }, []);

  // Prevent hydration mismatch
  if (!isMounted) {
    return <div className="text-gray-500">読み込み中...</div>;
  }

  if (isLoading) return <div>Loading...</div>;

  return user ? (
    <div>Welcome, {user.name}!</div>
  ) : (
    <a href="/auth/login">Login</a>
  );
}

❌ Port Conflict (EADDRINUSE: address already in use)

✅ Solution: Kill existing processes:

# Find and kill processes using port 3000
lsof -ti:3000 | xargs kill -9

# Or kill all node/next processes
pkill -f "node.*3000|next.*dev"

# Start on different port if needed
PORT=3001 pnpm dev

❌ API Route Implementation Issues

🔄 Updated Solution: Use the latest API implementation:

// ❌ Old approach (from earlier documentation)
import { handleAuth } from '@gftdcojp/gftd-orm/nextjs-auth0';
export const { GET, POST } = handleAuth();

// ✅ Latest correct implementation
import { createNextJsAuth0Client, auth0Middleware } from '@gftdcojp/gftd-orm/nextjs-auth0';

// Option 1: Direct middleware (recommended)
export default auth0Middleware;

// Option 2: Custom client configuration
const client = createNextJsAuth0Client({
  domain: process.env.AUTH0_DOMAIN!,
  clientId: process.env.AUTH0_CLIENT_ID!,
  clientSecret: process.env.AUTH0_CLIENT_SECRET!,
  appBaseUrl: process.env.AUTH0_BASE_URL!,
  secret: process.env.AUTH0_SECRET!,
});

export const GET = client.middleware.bind(client);
export const POST = client.middleware.bind(client);

❌ Environment Variables Missing

✅ Required Setup: Ensure these environment variables are configured:

# Required (must be individually configured)
AUTH0_CLIENT_SECRET=your-client-secret                       # Get from Auth0 Dashboard
AUTH0_SECRET=your-32-char-secret-key                         # Session encryption (32+ chars)
AUTH0_BASE_URL=http://localhost:3000                         # Your app's base URL

# Optional (SDK defaults available)
# AUTH0_DOMAIN=auth.gftd.ai                                  # SDK default
# AUTH0_CLIENT_ID=k0ziPQ6IkDxE1AUSvzx5PwXtnf4y81x0          # SDK default
# AUTH0_AUDIENCE=https://auth.gftd.ai/api/v2/               # SDK default

9. New Features Available After Migration

Once migrated, you get access to enterprise features:

// Organizations support
import { createAuth0Client } from '@gftdcojp/gftd-orm/auth0-integration';

// Edge runtime support
import { createEdgeAuth0Client } from '@gftdcojp/gftd-orm/nextjs-auth0-edge';

// Custom session stores

🌐 Translation Features (Weblate Integration)

🔧 Translation Management

GFTD ORM integrates with Weblate for comprehensive translation management, supporting multi-language applications with enterprise-grade features.

Setup Translation Client

// app/layout.tsx
import { TranslatorClient, translatorConfig } from '@gftdcojp/gftd-orm/translator';

// Initialize translator
const translator = TranslatorClient.getInstance(translatorConfig.fromEnv());

// Set current user for tenant-specific translations
translator.setCurrentUser(user);

React Hook for Translation

// components/TranslatedComponent.tsx
import { useTranslator } from '@gftdcojp/gftd-orm/hooks';

export function TranslatedComponent() {
  const { t, currentLanguage, changeLanguage, supportedLanguages } = useTranslator({
    language: 'en',
    namespace: 'components',
    // No API key or user required for read-only operations
  });

  return (
    <div>
      <h1>{t('welcome.title', { name: 'User' })}</h1>
      <p>{t('welcome.description')}</p>
      
      <select value={currentLanguage} onChange={(e) => changeLanguage(e.target.value)}>
        {supportedLanguages.map(lang => (
          <option key={lang} value={lang}>{lang}</option>
        ))}
      </select>
    </div>
  );
}

Translation Management (Admin)

// pages/admin/translations.tsx
import { useTranslatorAdmin } from '@gftdcojp/gftd-orm/hooks';

export function TranslationAdmin() {
  const { 
    projects, 
    createProject, 
    initializeTenantProject,
    canManage 
  } = useTranslatorAdmin();

  if (!canManage) return <div>Access denied</div>;

  const handleCreateTenantProject = async (tenantId: string) => {
    await initializeTenantProject(tenantId);
  };

  return (
    <div>
      <h1>Translation Management</h1>
      {projects.map(project => (
        <div key={project.slug}>
          <h2>{project.name}</h2>
          <p>Languages: {project.languages.join(', ')}</p>
          <p>Progress: {project.stats.translated_percent}%</p>
        </div>
      ))}
      
      <button onClick={() => handleCreateTenantProject('tenant-123')}>
        Create Tenant Project
      </button>
    </div>
  );
}

Translation Statistics

// components/TranslationStats.tsx
import { useTranslationStats } from '@gftdcojp/gftd-orm/hooks';

export function TranslationStats({ language }: { language: string }) {
  const { stats, progressInfo, loading } = useTranslationStats(language);

  if (loading) return <div>Loading...</div>;

  return (
    <div className="translation-stats">
      <h3>Translation Progress: {language}</h3>
      <div className="progress-bar">
        <div 
          className="progress-fill" 
          style={{ width: `${progressInfo?.translatedPercent || 0}%` }}
        />
      </div>
      <p>
        {progressInfo?.translated} / {progressInfo?.total} strings translated
      </p>
      <p>
        {progressInfo?.wordsTranslated} / {progressInfo?.wordsTotal} words
      </p>
    </div>
  );
}
