// backend/services/greetings.js
export function getGreeting(name) {
  return `Hello, ${name}!`;
}

Import in routes:

// core/routes.js
import { getGreeting } from '../backend/services/greetings.js';

app.get('/api/greet/:name', (c) => {
  const name = c.req.param('name');
  return c.json({ message: getGreeting(name) });
});
