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.
Create a Supabase project
Go to database.new and create a new Supabase project.
When your project is up and running, go to the Table Editor, create a new table and insert some data.
Alternatively, you can run the following snippet in your project's SQL Editor. This will create a instruments
table with some sample data.
12345678910111213-- Create the tablecreate table instruments ( id bigint primary key generated always as identity, name text not null);-- Insert some sample data into the tableinsert into instruments (name)values ('violin'), ('viola'), ('cello');alter table instruments enable row level security;
Make the data in your table publicly readable by adding an RLS policy:
1234create policy "public can read instruments"on public.instrumentsfor select to anonusing (true);
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:
Project URL
Anon key
Add a getInstruments
function to fetch the data and display the query result to the page.
123456789101112131415161718192021222324252627import { useEffect, useState } from "react"; import { createClient } from "@supabase/supabase-js"; const supabase = createClient("https://<project>.supabase.co", "<your-anon-key>"); function App() { const [instruments, setInstruments] = useState([]); useEffect(() => { getInstruments(); }, []); async function getInstruments() { const { data } = await supabase.from("instruments").select(); setInstruments(data); } return ( <ul> {instruments.map((instrument) => ( <li key={instrument.name}>{instrument.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 instruments.
1npm run dev
