開始使用 Firebase Data Connect

透過集合功能整理內容 你可以依據偏好儲存及分類內容。

import React from 'react';
import ReactDOM from 'react-dom/client';

// Generated queries.
// Update as needed with the path to your generated SDK.
import { listMovies, ListMoviesData } from '@movie-app/movies';

function App() {
  const [movies, setMovies] = useState<ListMoviesData['movies']>([]);
  useEffect(() => {
    listMovies.then(res => setMovies(res.data));
  }, []);
  return (
    movies.map(movie => <h1>{movie.title}</h1>);
  );
}

const root = ReactDOM.createRoot(document.getElementById('root'));
root.render(<App />);
