cloudflare-hono

To type Cloudflare Worker Env bindings in a Hono app, import the Env type from your generated worker-configuration.d.ts file and pass it to the Hono constructor using new Hono<{ Bindings: Env }>(). This enables type-safe access to runtime environment variables via c.env.

Hono bindings are untyped when the Hono instance is not configured with the Cloudflare Worker Env type. You must wrap the Env type imported from worker-configuration using new Hono<{ Bindings: Env }>() to ensure compile-time type checks and proper autocomplete.

You generate types for Cloudflare Worker environment variables by running the wrangler types command in your project directory. This creates a worker-configuration.d.ts file containing the Env interface, which you then import into your Hono application.

Yes, you can use wrangler types with Hono for compile-time checks. By importing the Env type from the generated worker-configuration.d.ts file and passing it to new Hono<{ Bindings: Env }>(), you enforce type-safe runtime access to environment bindings.

The best way to access environment variables in Hono routes is by typing the Hono instance with Cloudflare Worker Env bindings. After configuring new Hono<{ Bindings: Env }>(), you directly access properties like c.env.ZEROSPIN_DATABASE within your route handlers with full autocomplete.
