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 the create-react-app command.
1npx create-react-app my-app
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 index.js, create a Supabase client using your Project URL and public API (anon) key.
Add a getCountries function to fetch the data and log the query result to the browser console.
import { createClient } from '@supabase/supabase-js'
const supabase = createClient('https://<project>.supabase.co', '<your-anon-key>')
async function getCountries() {
const countries = await supabase.from('countries').select()
console.log(countries)
}
getCountries()
Start the app
Start the app, go to http://localhost:3000 in a browser, and open the browser console and you should see the list of countries.
1npm start
