Front-End Integration in React 19

Integrating React 19 with APIs, state management, and third-party libraries is essential for building dynamic applications.

API Integration

  • Use Axios, Fetch, or React Query for REST API calls.
  • For GraphQL, use Apollo Client or urql.
  • Store API endpoints in environment variables.
  • Handle loading, error, and success states in UI.

Example: Fetch Data with React Query

import { useQuery } from '@tanstack/react-query';
function User() {
  const { data, error, isLoading } = useQuery(['user'], () => fetch('/api/user').then(res => res.json()));
  if (isLoading) return <div>Loading...</div>;
  if (error) return <div>Error: {error.message}</div>;
  return <div>{data.name}</div>;
}

State Management

  • Use Context API, Redux, or Zustand for global state.
  • Organize state logic in src/hooks/ or src/store/.
  • Use custom hooks for local state and logic reuse.

Routing

  • Use React Router for client-side navigation.
  • Define routes in src/pages/ or src/routes/.
  • Use route guards for authentication and authorization.

Third-Party Libraries

  • Integrate UI libraries (MUI, Chakra UI, Ant Design) for ready-made components.
  • Use charting libraries (Chart.js, Recharts) for data visualization.
  • Always check compatibility with React 19 and TypeScript support.

Best Practices

  • Centralize API logic in hooks or services.
  • Handle errors and loading states gracefully.
  • Keep third-party dependencies up to date.
