Use Supabase with Hono

1. Create a Supabase project#

To start, you need a Supabase project.

Create a new Supabase project from the Dashboard of any organization you belong to.

2. Set up your database#

When your Supabase project is up and running, create an instruments table with some sample data. Then set only the privileges each Postgres role needs, add Row Level Security (RLS) for enhanced security for database data by default, and create an RLS policy to make the data in the table publicly readable.

Do these steps within your project's dashboard by copying and running the snippet in your project's SQL Editor.

1
-- Create the table
2
create table instruments (
3
  id bigint primary key generated always as identity,
4
  name text not null
5
);
6
7
-- Insert sample data into the table
8
insert into instruments (name)
9
values
10
  ('violin'),
11
  ('viola'),
12
  ('cello');
13
14
-- Grant the privileges the role needs, which is read access
15
grant select on public.instruments to anon;
16
17
-- Enable row level security for the table
18
alter table instruments enable row level security;
19
20
-- Create a policy to allow the anon role to read from the instruments table
21
create policy "public can read instruments"
22
on public.instruments
23
for select to anon
24
using (true);

3. Create a Hono app#

Bootstrap the Hono example app from the Supabase Samples using the CLI.

1
npx supabase@latest bootstrap hono

4. Install Agent Skills (optional)#

Supabase's Agent Skills is a curated set of instructions that give your AI agent procedural knowledge about working with Supabase.

To install, run the following command in the root of your project:

1
npx skills add supabase/agent-skills

5. Install the Supabase client library#

The package.json file in the project includes the necessary dependencies, including @supabase/supabase-js and @supabase/ssr to help with server-side auth.

1
npm install

6. Set up the required environment variables#

Copy the .env.example file to .env and update the values with your Supabase project URL and publishable key, which you can get from the helper below, or from the project Connect panel.

Lastly, enable anonymous sign-ins in the Auth settings.

1
cp .env.example .env

Get API details#

To interact with data in database tables, you use the client libraries that wrap the auto-generated Data API endpoints, authenticating using the Project URL and key from the project Connect dialog.

7. Start the app#

Start the app, go to http://localhost:5173.
