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. Set up your database#
When your Supabase project is up and running, create an instruments table with some sample data.
Then set a secure baseline by setting 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 your table publicly readable.
You can click this button to prefill all the SQL needed in the SQL editor of your project in the Dashboard.
Prefill SQLIf 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.
3. Create a Hono app#
Bootstrap the Hono example app from the Supabase Samples using the CLI.
1npx supabase@latest bootstrap hono4. 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.
5. 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 .env6. Start the app#
Start the app, go to http://localhost:5173.
