The code above works well for normal use cases.
However, if you want to use the RPC feature, you can get the correct type by chaining as follows.
// authors.ts
import { Hono } from 'hono'
const app = new Hono()
.get('/', (c) => c.json('list authors'))
.post('/', (c) => c.json('create an author', 201))
.get('/:id', (c) => c.json(`get ${c.req.param('id')}`))
export default app
export type AppType = typeof app
If you pass the type of the app to hc, it will get the correct type.
import type { AppType } from './authors'
import { hc } from 'hono/client'
// 😃
const client = hc<AppType>('http://localhost') // Typed correctly
