Is it possible to make InitApp as async in Factory helper?

[fuhaiq]

I'm trying to introduce honojs as the new engine for my existing project. I need to set many routing rules stored in DB through the program.
I saw there's a helper named createFactory which accept initApp. But this's a normal function rather than async

hono/src/helper/factory/index.ts

Line 18 in 882e75a

type InitApp<E extends Env = Env> = (app: Hono<E>) => void

what I basically want is like

export default createFactory<Env>({
  initApp: async (app) => {
    const {id, method, path} = await DB.get() // get routes from DB
    const handler = handlerMap.get(id)
    app.on(method, path, handler)
  },
})

Is there any graceful way achieve this? Thanks!
