extend authenticator methods

[rodbs]

authenticator exposes the isAuthenticated method.
I'd like to add more info to the user session (for instance, when a user is subscribed), and then to use a kind of
authenticator.isSubscribed in the loader.
Is there an easy way to extend authenticator methods to add more checks? I'd appreciate it any inputs about it !
thx!

You own the session storage, this means you can store anything in the session and grab it as usual in Remix

async function isSubscribed(request: Request) {
  let session = await sessionStorage.getSession(request.headers.get("cookie"))
  let isSubscribed = session.get("isSubscribed")
  if (typeof isSubscribed === "boolean") return isSubscribed
  return false;
}

export async function loader({ request }: LoaderArgs) {
  if (await isSubscribed(request)) {
    // do something
  } else {
    // do something else
  }
}

Another option is to store that data in the value returned by the strategy verify callback, then you can use the isAuthenticated method.

export async function loader({ request }: LoaderArgs) {
  let { isSubscribed } = await authenticator.isAuthenticated(request, {
    failureRedirect: "/login"
  })
  // your code here
}

Ok, I've got it the first one.
But what do you mean by the 'strategy verify callback'? I though isAuthenticated always returned the user object?

Every strategy receives a function, that is the verify callback, there you return what your app considers the user object, you can return anything there, so you could add the isSubscribed boolean there.

ok, understood. Thx!!
