Error Handling

Define custom error handlers to handle all errors in your app.

Usage

const app = new Kyrin({
  onError: (err, c) => {
    console.error(err);
    return c.json({ error: err.message }, 500);
  }
});

Validation Errors

Kyrin automatically handles Zod validation errors and returns 400 Bad Request. See Routes for more details.

Default Behavior

If you don't define onError:

• Development mode: Shows error details with stack trace
• Production mode: Shows "Internal Server Error" only
