const app = new Hono<{ Variables: Variables }>()

app.use(async (c, next) => {

Also highly recommend steering clear of the JWT approach Sessions are the way and have always been, JWT's aren't meant for the web

I'm using jwt with Refresh token tho i have multiple instance of hono that get combined at index , so do i have to pass Variable to every hono instance

create a function to generate with types

type Variables = {
  jwtPayload: string
}


export function baseHono() {
  return new Hono<{ Variables: Variables }>()
}

export function protectedHono(){
  return baseHono().use(...)
}

type Variables = {
  jwtPayload: string
}


export function baseHono() {
  return new Hono<{ Variables: Variables }>()
}

export function protectedHono(){
  return baseHono().use(...)
}

where you would use new Hono you use baseHono()

one more thing i could add protection middleware and call it protectedHono right

you can change for whatever you want from there idk the exact syntax but you get the point i edited the message for clarity sake
