Getting Started

Use Supabase with Next.js

Learn how to create a Supabase project, add some sample data, and query from a Next.js app.


1

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 notes table with some sample data.

SQL_EDITOR

_14
-- Create the table
_14
create table notes (
_14
id bigint primary key generated always as identity,
_14
title text not null
_14
);
_14
_14
-- Insert some sample data into the table
_14
insert into notes (title)
_14
values
_14
('Today I created a Supabase project.'),
_14
('I added some data and queried it from Next.js.'),
_14
('It was awesome!');
_14
_14
alter table notes enable row level security;

Make the data in your table publicly readable by adding an RLS policy:

SQL_EDITOR

_10
create policy "public can read notes"
_10
on public.notes
_10
for select to anon
_10
using (true);

2

Create a Next.js app

Use the create-next-app command and the with-supabase template, to create a Next.js app pre-configured with:

Terminal

_10
npx create-next-app -e with-supabase

3

Declare Supabase Environment Variables

Rename .env.example to .env.local and populate with your Supabase connection variables:

Project URL
Anon key
.env.local

_10
NEXT_PUBLIC_SUPABASE_URL=<SUBSTITUTE_SUPABASE_URL>
_10
NEXT_PUBLIC_SUPABASE_ANON_KEY=<SUBSTITUTE_SUPABASE_ANON_KEY>

4

Query Supabase data from Next.js

Create a new file at app/notes/page.tsx and populate with the following.

This will select all the rows from the notes table in Supabase and render them on the page.

app/notes/page.tsx
utils/supabase/server.ts

_10
import { createClient } from '@/utils/supabase/server';
_10
_10
export default async function Notes() {
_10
const supabase = await createClient();
_10
const { data: notes } = await supabase.from("notes").select();
_10
_10
return <pre>{JSON.stringify(notes, null, 2)}</pre>
_10
}

5

Start the app

Run the development server, go to http://localhost:3000/notes in a browser and you should see the list of notes.

Terminal

_10
npm run dev
