5. Install the Nhost package for React

   Navidate to the React application and install @nhost/react.

   Terminal

   cd nhost-react-quickstart && npm install @nhost/react
   

6. Configure the Nhost client and fetch the list of movies

   Create a new file with the following code to creates the Nhost client.

   ./src/lib/nhost.js

   import { NhostClient } from "@nhost/react";
   
   export const nhost = new NhostClient({
     subdomain: "<subdomain>",
     region: "<region>",
   })
   

   Replace <subdomain> and <region> with the subdomain and region for the project

   Finally, update ./src/App.jsx to fetch the list of movies.

   src/App.jsx

   import { useEffect, useState } from "react";
   import { NhostProvider } from "@nhost/react";
   import { nhost } from './lib/nhost'	
   
   const getMovies = `
     query {
       movies {
         title
         genre
         rating
       }
     }
   `;  
   
   function App() {
     return (
       <NhostProvider nhost={nhost}>
         <Home />
       </NhostProvider>
     );
   }
   
   function Home() {
     const [loading, setLoading] = useState(true);
     const [movies, setMovies] = useState([]);
   
     useEffect(() => {
       async function fetchMovies() {
         setLoading(true);
         const { data, error } = await nhost.graphql.request(getMovies);
   
         setMovies(data.movies);
         setLoading(false);
       }
   
       fetchMovies();
     }, []);
   
     return (
       <div>
         {loading ? (
           <p>Loading...</p>
         ) : (
           <table>
             <tbody>
               {movies.map((movie, index) => (
                 <tr key={index}>
                   <td>{movie.title}</td>
                   <td>{movie.genre}</td>
                   <td>{movie.rating}</td>
                 </tr>
               ))}
             </tbody>
