How to ideally protecting routes with Layout

 [login]-> [getSession & wrap in server fn with key]-> [call in layout]-> [also call in page]-> [called twice]

// server.ts
export const authorize = query(async ()=> {
  "use server"
  
  const req = getRequestEvent()?.request // solid/web
  const sesh = await getSession(req, authOptions) // auth-js

  // this called twice
  console.log(sesh)

  if(!sesh) throw redirect("/login")
  return sesh
},"sesh") 

export const getPosts = query(async ()=> {
  "use server"

  await authorize()

  const someQuery = await db.query()

  return someQuery
}, "posts")

export const getPostById = query(async (id: string)=> {
  "use server"

  await authorize()

  const someQuery = await db.query(id)

  return someQuery
}, "post-by-id")

// some-layout.tsx
export route = {
  preload: ()=> {
    authorize()
  }
}

// this called once
export default function Layout(){
  const sesh = createAsync(()=> authorize())
}

// some-layout/random-post.tsx
export route = {
  preload: ({ location })=> {
    const id = ...

    getPostById(id)
    getPosts()
  }
}

// this called once
export default function PostPage(props){
  const posts = createAsync(()=> getPosts())
  const post = createAsync(()=> getPostById(props.etc.id))
}
