Query D1 from Hono

Hono is a fast web framework for building API-first applications, and it includes first-class support for both Workers and Pages.

When using Workers:

• Ensure you have configured wrangler.toml to bind your D1 database to your Worker.
• You can access your D1 databases via Hono’s Context Open external link parameter: bindings Open external link are exposed on context.env. If you configured a binding named DB, then you would access D1’s client API methods via c.env.DB.
• Refer to the Hono documentation for Cloudflare Workers Open external link .

If you are using Pages Functions:

1. Bind a D1 database to your Pages Function.
2. Pass the --d1 BINDING_NAME=DATABASE_ID flag to wrangler dev when developing locally. BINDING_NAME should match what call in your code, and DATABASE_ID should match the database_id defined in your wrangler.toml: for example, --d1 DB=xxxx-xxxx-xxxx-xxxx-xxxx.
3. Refer to the Hono guide for Cloudflare Pages Open external link .

The following examples show how to access a D1 database bound to DB from both a Workers script and a Pages Function:
