Open your terminal and start a new React project using Create React App:
```shell
npx create-react-app my-app
cd my-app
```

Install the necessary dependencies for Apollo Client, GraphQL, and Supabase:
```shell
npm install @apollo/client graphql @supabase/supabase-js
```

Create a new file called supabaseClient.js in the src directory:
```javascript
import { createClient } from '@supabase/supabase-js';

const supabaseUrl = 'https://your-supabase-url.supabase.co';
const supabaseAnonKey = 'your-anon-key';

export const supabase = createClient(supabaseUrl, supabaseAnonKey);
```

Make sure to replace supabaseUrl and supabaseAnonKey with the values you got from the Supabase dashboard.

Create a new file called apolloClient.js in the src directory:
```javascript
import { ApolloClient, InMemoryCache, HttpLink } from '@apollo/client';

const supabaseGraphQLUrl = 'https://your-supabase-url.supabase.co/graphql/v1';

const client = new ApolloClient({
link: new HttpLink({
uri: supabaseGraphQLUrl,
headers: {
apikey: 'your-anon-key',
},
}),
cache: new InMemoryCache(),
});

export default client;
```

Replace supabaseGraphQLUrl and apikey with the correct Supabase endpoint and anon key.

Open index.js or App.js and wrap your main component with ApolloProvider:
```javascript
import React from 'react';
import ReactDOM from 'react-dom';
import App from './App';
import { ApolloProvider } from '@apollo/client';
import client from './apolloClient';

ReactDOM.render(

Inside any React component, you can use Apollo Client hooks like useQuery to interact with your Supabase GraphQL endpoint:
```javascript
import React from 'react';
import { useQuery, gql } from '@apollo/client';

const GET_DATA = gql`
query {
your_table_name {
id
column1
column2
}
}
`;

const YourComponent = () => {
const { loading, error, data } = useQuery(GET_DATA);

if (loading) return

Loading...

Error :(

return (

export default YourComponent;
```

Swap out the GET_DATA query with your Supabase table and column names. Use the component as needed in your app.
