  • Modern Stack: Uses the latest React ecosystem tools and practices
  • Better DX: Superior developer experience with TypeScript and modern tooling
  • Smaller Bundle: More efficient code splitting and tree shaking
  • SEO Optimized: Server-side rendering capabilities

Do I need to know ABP Framework to use ABP React?​

While basic ABP Framework knowledge is helpful, ABP React is designed to be accessible to React developers. The template handles most ABP integrations automatically, and our documentation covers the ABP-specific concepts you need to know.

Is ABP React production-ready?​

Yes, ABP React is production-ready and is actively used in production applications. It includes comprehensive testing, CI/CD pipelines, and follows industry best practices.

🛠️ Installation & Setup​

What are the system requirements?​

  • Node.js: 18.0 or higher
  • pnpm: 8.0 or higher (recommended package manager)
  • .NET 8 SDK: For backend development
  • Modern Browser: Chrome 90+, Firefox 88+, Safari 14+, Edge 90+

Why use pnpm instead of npm or yarn?​

We recommend pnpm because it's:

  • Faster: More efficient installation and caching
  • Smaller: Reduces disk space usage with symlinks
  • Stricter: Better dependency resolution and security
  • Compatible: Works with all npm packages

Can I use npm or yarn instead of pnpm?​

Yes, you can use npm or yarn, but you may need to:

  • Delete pnpm-lock.yaml
  • Update scripts in package.json
  • Handle potential dependency resolution differences

How do I update to the latest version?​

For template updates:

# Check current version
npm list -g Anto.Abp.React.Template

# Update template
dotnet new uninstall Anto.Abp.React.Template
dotnet new install Anto.Abp.React.Template

# Create new project with latest template
dotnet new abp-react -o my-updated-project

For project dependencies:

# Update all dependencies
pnpm update

# Update specific dependency
pnpm update @next/bundle-analyzer

🔐 Authentication & Security​

How does authentication work?​

ABP React uses NextAuth.js for authentication, integrated with ABP Framework's authentication system:

  1. JWT Tokens: Secure token-based authentication
  2. Session Management: Automatic session handling and refresh
  3. Multiple Providers: Support for credentials, OAuth, and more
  4. Role-Based Access: Integration with ABP's permission system

Can I use social login providers?​

Yes, ABP React supports multiple authentication providers:

  • Google OAuth
  • GitHub OAuth
  • Microsoft OAuth
  • Facebook OAuth
  • Custom OAuth providers

Configure them in your environment variables and NextAuth configuration.

How do I handle permissions?​

ABP React includes built-in permission handling:

// Check permissions in components
const { hasPermission } = usePermissions();

if (!hasPermission('Users.Create')) {
  return <div>Access denied</div>;
}

// Use permission wrapper
<PermissionWrapper permission="Users.Edit">
  <EditUserButton />
</PermissionWrapper>

Is the application secure?​

Yes, ABP React follows security best practices:

  • JWT Token Security: Secure token storage and transmission
  • CSRF Protection: Built-in CSRF protection
  • Input Validation: Client and server-side validation
  • XSS Prevention: React's built-in XSS protection
  • Permission Checks: Comprehensive authorization system

🌐 Multi-tenancy​

What is multi-tenancy?​

Multi-tenancy allows a single application instance to serve multiple tenants (organizations) with isolated data and configurations. Each tenant has their own data, users, and settings.

How do I enable multi-tenancy?​

Multi-tenancy is enabled by default in ABP React. You can configure it in your environment:

NEXT_PUBLIC_ENABLE_MULTI_TENANCY=true

How does tenant switching work?​

ABP React provides automatic tenant switching:

  • Subdomain-based: tenant1.myapp.com
  • Header-based: __tenant header
  • Manual switching: Tenant switcher component

Can I disable multi-tenancy?​

Yes, you can disable multi-tenancy:

NEXT_PUBLIC_ENABLE_MULTI_TENANCY=false

This will hide tenant-related UI and functionality.

📱 UI & Components​

What UI library does ABP React use?​

ABP React uses shadcn/ui components built on top of:

  • Radix UI: For accessible, unstyled components
  • Tailwind CSS: For utility-first styling
  • Lucide React: For icons

Can I customize the theme?​

Yes, ABP React supports comprehensive theming:

// Configure theme in tailwind.config.js
module.exports = {
  theme: {
    extend: {
      colors: {
        primary: {
          50: '#f0f9ff',
          500: '#3b82f6',
          900: '#1e3a8a',
        },
      },
    },
  },
};

Are the components responsive?​

Yes, all components are built with responsive design:

  • Mobile-first: Designed for mobile devices first
  • Breakpoint System: Tailwind's responsive breakpoints
  • Touch-friendly: Optimized for touch interactions

Can I use other UI libraries?​

Yes, you can integrate other UI libraries:

  • Material-UI: For Material Design components
  • Ant Design: For enterprise-class UI
  • Chakra UI: For modular component library
  • Custom Components: Build your own component library

🔧 Development​

How do I add new pages?​

With Next.js App Router, creating pages is simple:

// app/users/page.tsx
export default function UsersPage() {
  return <div>Users Page</div>;
}

// app/users/[id]/page.tsx
export default function UserDetailPage({ params }: { params: { id: string } }) {
  return <div>User ID: {params.id}</div>;
}

How do I add new API endpoints?​

Create API routes in the app/api directory:

// app/api/users/route.ts
import { NextRequest, NextResponse } from 'next/server';

export async function GET(request: NextRequest) {
  // Handle GET request
  return NextResponse.json({ users: [] });
}

export async function POST(request: NextRequest) {
  // Handle POST request
  const body = await request.json();
  return NextResponse.json({ success: true });
}

How do I customize the build process?​

Customize the build in next.config.mjs:

/** @type {import('next').NextConfig} */
const nextConfig = {
  experimental: {
    appDir: true,
  },
  images: {
    domains: ['example.com'],
  },
  env: {
    CUSTOM_KEY: process.env.CUSTOM_KEY,
  },
};

export default nextConfig;

How do I add custom middleware?​

Add middleware in middleware.ts:

import { NextResponse } from 'next/server';
import type { NextRequest } from 'next/server';

export function middleware(request: NextRequest) {
  // Add custom logic
  return NextResponse.next();
}

export const config = {
  matcher: '/admin/:path*',
};

📊 Performance​

How do I optimize performance?​

ABP React includes several performance optimizations:

  1. Code Splitting: Automatic code splitting with Next.js
  2. Image Optimization: Next.js Image component
  3. Bundle Analysis: Built-in bundle analyzer
  4. Caching: React Query for data caching
  5. Lazy Loading: Component lazy loading

How do I analyze bundle size?​

Use the built-in bundle analyzer:

# Analyze bundle size
pnpm analyze

# This will open a visual representation of your bundle

Why is my application slow?​

Common performance issues and solutions:

  1. Large Bundle: Use code splitting and lazy loading
  2. Unnecessary Re-renders: Use React.memo and useMemo
  3. Heavy API Calls: Implement proper caching
  4. Large Images: Use Next.js Image optimization
  5. Memory Leaks: Check for uncleaned event listeners

🔄 API Integration​

How do I generate the API client?​

The API client is automatically generated from your ABP backend:

# Generate client
pnpm generate-client

# Specify custom API URL
pnpm generate-client --input https://your-api.com/swagger/v1/swagger.json

What if my API changes?​

Regenerate the client whenever your API changes:

# Regenerate client
pnpm generate-client

# This will update types and service methods

How do I handle API errors?​

ABP React includes comprehensive error handling:

// Global error handler
export const handleApiError = (error: unknown) => {
  if (error instanceof ApiError) {
    // Handle ABP-specific errors
    if (error.body?.error?.message) {
      toast.error(error.body.error.message);
    }
  }
};

// Component-level error handling
const { data, error, isLoading } = useUsers();

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

Can I use REST APIs from other frameworks?​

Yes, ABP React can work with any REST API:

// Custom API client
const customApi = axios.create({
  baseURL: 'https://api.external.com',
  timeout: 5000,
});

// Custom hook
export const useCustomData = () => {
  return useQuery({
    queryKey: ['custom-data'],
    queryFn: () => customApi.get('/data').then(res => res.data),
  });
};

test('renders user profile', () => {
  render(<UserProfile user={mockUser} />);
  expect(screen.getByText('John Doe')).toBeInTheDocument();
});

How do I test API calls?​

Use Mock Service Worker (MSW):

// Setup MSW handlers
export const handlers = [
  rest.get('/api/users', (req, res, ctx) => {
    return res(ctx.json({ users: mockUsers }));
  }),
];

// Test hook
test('fetches users', async () => {
  const { result } = renderHook(() => useUsers(), {
    wrapper: QueryWrapper,
  });
  
  await waitFor(() => {
    expect(result.current.data).toEqual(mockUsers);
  });
});
