If a session is refreshed when accessed through /api/auth/session during
a SSR then the Set-Cookie header was lost. Pass this along to the
client in this case to keep the session alive.
The caching layer of Nuxt assumes no entry exists if it's nullish. This
causes null to be treated as if the resource needs to be fetched. Use
false instead.
If the returned value of the fetched endpoint is blank that gets
converted to undefined, which confuses the request sharing between the
client and server causing the session to be requested on both sides.
Transform value to null if it's blank so that the session fetch is
de-duplicated.
Provide a basic account system with login and server side session store
identified by a cookie. Upon successful login a signed session cookie
is set by the server with the session stored on the server identifying
which account it is logged in as. The client uses a shared useFetch on
the session endpoint to identify if it's logged in and which account it
is logged in as, and refreshes this when loggin in or out.
