Use Supabase with Hono
Learn how to create a Supabase project, add some sample data to your database, secure it with auth, and query the data from a Hono app.
1. Create a Supabase project#
Before you can use Supabase, you need a Supabase project. You can create a project visually in the Dashboard or programmatically using the Management API.
Create a new Supabase project from the Dashboard of any organization you belong to.
You can also use database.new to create a new Supabase project.
2. Install agent skills (optional)#
Agent Skills are curated instruction sets that give your AI agent procedural knowledge about working with Supabase.
Install them in your project with:
1npx skills add supabase/agent-skills3. 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.
Save some steps by clicking here to prefill the SQL in the SQL Editor, and then clicking Run.
Or do this manually in your project's SQL Editor, by pasting the SQL below, and clicking Run.
1-- Create the table2create table instruments (3 id bigint primary key generated always as identity,4 name text not null5);67-- Insert sample data into the table8insert into instruments (name)9values10 ('violin'),11 ('viola'),12 ('cello');1314-- Grant the privileges the role needs, which is read access15grant select on public.instruments to anon;1617-- Enable row level security for the table18alter table instruments enable row level security;1920-- Create a policy to allow the anon role to read from the instruments table21create policy "public can read instruments"22on public.instruments23for select to anon24using (true);If you disabled the Data API during project setup, enable it in the Integrations > Data API section of the Dashboard and expose the specific tables or functions you want to access. To automatically grant access for new tables and functions in public, enable Automatically expose new tables.
4. Create a Hono app#
Bootstrap the Hono example app from the Supabase Samples using the CLI.
1npx supabase@latest bootstrap hono5. 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.
1npm installGet 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.
Project URL
Publishable key
Read the API keys docs for a full explanation of all key types, their uses, and where to find them.
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 above, or from the project Connect panel.
Lastly, enable anonymous sign-ins in the Auth settings.
1cp .env.example .env7. Start the app#
Start the app, go to http://localhost:5173.
