How can we manage session in the postgraphile app?

[raviSussol]

Summary

Hi, I'm new to the Postgraphile and I've just started looking at this starter kit to know about how the session is managed in this postgraphile app. I saw there are 2 tables being used for a session management in this starter kit, 1. connect_pg_simple_sessions 2. sessions. And I've seen that the sessions table gets updated in every valid graphql request made to the database which keeps track of user that made request and his/her last active time. Also it has been used to track user login while login request is made through login function in the database where on successful login a new record is inserted into this table. But the connect_pg_simple_sessions table has just been used or initialized at the time of middleware setup on the server. So my question is if we're using the sessions table to track user logins and every graphql request made by user then what is the use of connect_pg_simple_sessions table within the app? How can we track user's session after their login like we normally do in normal express js app using any session library (i.e. like this conect pg simple for instance)? How can we send session inside a cookie to the user after user logs in in the postgraphile app?

Additional context

Trying to understand the session management logic flow in the postgraphile with the help of this starter kit so no additional context but some above questions.

You don't need it; it's only there in case you don't want to use the redis session provider (or provide your own).

You can do it like you normally do in a normal express js app using any session library. You can replace the session store with whatever you want:
