I did try

import { hc } from "hono/client";
import { auth } from "@server/routes/auth";

const client = hc<typeof auth>("/");
export const api = client.api;

import { hc } from "hono/client";
import { auth } from "@server/routes/auth";

const client = hc<typeof auth>("/");
export const api = client.api;

come out

Are you in a monorepo? If so, are you sure you are using the same hono version on both backend and frontend If not, then what the fuck is going on, this doesn't make sense Also, please export the type from the backend, don't do typeof auth from the frontend Instead do export type AUTH = typeof auth; and then import type { AUTH } from "backend..."; and use that type

shcworkOP•2mo ago

Yes, I use monorepo. Yes, both using [email protected]. Will try on that method

still appear this error 😅

@shcwork using generated instead of inferred types may help, but that's usually for type elision you're doing a lot of abstraction, which is increasing your app's complexity in a way that could be contributing to your issue i'm pretty sure your implementation of apiRouters is incompatible with hono RPC, for example why are you iteratively registering routes?

shcworkOP•2mo ago

My intention is to make the route api as file base (/api/auth, /api/expenses) without user define every single route app.route('/auth', auth) app.route('/expenses', expenses) ... If my implementation fail, I will back to the hono ori method.

ambergristle•2mo ago

typescript can't infer from an iteration like that so hono RPC won't work defining each route explicitly is also more transparent + easier to reason with. iteratively registering routes is almost never a good idea, imo

shcworkOP•2mo ago

Ic, I wil give up my method and adapt the hono ori method, thx for explaination.
