* This is a slimmed down version of the `getServerSession` function from
|
||
|
|
* `next-auth`.
|
||
|
|
*
|
||
|
|
* Instead of requiring the entire options object for NextAuth, we create
|
||
|
|
* a compatible session using information from the incoming token.
|
||
|
|
*
|
||
|
|
* The downside to this is that we won't refresh sessions if the users
|
||
|
|
* token has expired (30 days). This should be fine as we call `/auth/session`
|
||
|
|
* frequently enough on the client-side to keep the session alive.
