If you want to use a client, you should not use c.notFound() for the Not Found response. The data that the client gets from the server cannot be inferred correctly.
// server.ts
export const routes = new Hono().get(
'/posts',
zValidator(
'query',
z.object({
id: z.string(),
})
),
async (c) => {
const { id } = c.req.valid('query')
const post: Post | undefined = await getPost(id)
if (post === undefined) {
return c.notFound() // ❌️
}
return c.json({ post })
}
)
// client.ts
import { hc } from 'hono/client'
const client = hc<typeof routes>('/')
const res = await client.posts[':id'].$get({
param: {
id: '123',
},
})
const data = await res.json() // 🙁 data is unknown
Please use c.json() and specify the status code for the Not Found Response.
