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.
Create a Hono app
Bootstrap the Hono example app from the Supabase Samples using the CLI.
Terminal
1npx supabase@latest bootstrap honoInstall 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.
Terminal
1npm installSet up the required environment variables
Copy the .env.example file to .env and update the values with your Supabase project URL and publishable key.
Lastly, enable anonymous sign-ins in the Auth settings.

Publishable key
Terminal
1cp .env.example .envGet API details#
Now that you've created some database tables, you are ready to insert data using the auto-generated API.
To do this, you need to get the Project URL and key from the project Connect dialog.
Read the API keys docs for a full explanation of all key types and their uses.
Changes to API keys
Supabase is changing the way keys work to improve project security and developer experience. You can read the full announcement on GitHub.
The older anon and service_role keys will work until the end of 2026 but we strongly encourage switching to and using the new publishable (sb_publishable_xxx) and secret (sb_secret_xxx) keys now.
In most cases, you can get keys from the Project's Connect dialog, but if you want a specific key, you can find them in the Settings > API Keys section of the Dashboard.
- For legacy keys, copy the
anonkey for client-side operations and theservice_rolekey for server-side operations from the Legacy API Keys tab. - For new keys, open the API Keys tab, if you don't have a publishable key already, click Create new API Keys, and copy the value from the Publishable key section.
