Use Supabase with React
Learn how to create a Supabase project, add some sample data to your database, and query the data from a React app.
Set up a Supabase project with sample data
Create a new project in the Supabase Dashboard.
After your project is ready, create a table in your Supabase database using the SQL Editor in the Dashboard. Use the following SQL statement to create a countries table with some sample data.
-- Create the table
CREATE TABLE countries (
id SERIAL PRIMARY KEY,
name VARCHAR(255) NOT NULL
);
-- Insert some sample data into the table
INSERT INTO countries (name) VALUES ('United States');
INSERT INTO countries (name) VALUES ('Canada');
INSERT INTO countries (name) VALUES ('Mexico');
Create a React app
Create a React app using a Vite template.
1npm create vite@latest my-app -- --template react
Install the Supabase client library
The fastest way to get started is to use the supabase-js client library which provides a convenient interface for working with Supabase from a React app.
Navigate to the React app and install supabase-js.
1cd my-app && npm install @supabase/supabase-js
Query data from the app
In App.jsx, create a Supabase client using your Project URL and public API (anon) key.
Add a getCountries function to fetch the data and display the query result to the page.
import { useEffect, useState } from "react";
import { createClient } from "@supabase/supabase-js";
const supabase = createClient("https://<project>.supabase.co", "<your-anon-key>");
function App() {
const [countries, setCountries] = useState([]);
useEffect(() => {
getCountries();
}, []);
async function getCountries() {
const { data } = await supabase.from("countries").select();
setCountries(data);
}
return (
<ul>
{countries.map((country) => (
<li key={country.name}>{country.name}</li>
))}
</ul>
);
}
export default App;
Start the app
Start the app, go to http://localhost:5173 in a browser, and open the browser console and you should see the list of countries.
1npm run dev
