Alternatively, you can use module augmentation to extend NotFoundResponse interface. This allows c.notFound() to return a typed response:
// server.ts
import { Hono, TypedResponse } from 'hono'
declare module 'hono' {
interface NotFoundResponse
extends Response,
TypedResponse<{ error: string }, 404, 'json'> {}
}
const app = new Hono()
.get('/posts/:id', async (c) => {
const post = await getPost(c.req.param('id'))
if (!post) {
return c.notFound()
}
return c.json({ post }, 200)
})
.notFound((c) => c.json({ error: 'not found' }, 404))
export type AppType = typeof appNow the client can correctly infer the 404 response type.
