NodeJS / express session timing out early

Question

In my NodeJs / Express app, I'm using the standard session package and Passport to handle sessions and login. My problem is that the app kicks the user out after what feels like 10 minutes of inactiviy, and forces them to log-in again. My assumption is that it must be something to do with the session configuration, which with my limited understanding, I think is configured to allow 2 hours:

const session = require("express-session");
const PostgreSqlStore = require("connect-pg-simple")(session);


const sessionAge = 2 * 60 * 60 * 1000; // hour, min, sec, millisecond

var sessionConfig = {
    name: "mysite",
    secret: "verysecret",
    resave: true,
    saveUninitialized: false,
    proxy: trustedTypes,
    cookie: {
       key: "cookieKey",
       secure: true,
       sameSite: false,
       httpOnly: true,
       maxAge: sessionAge,
    },
    store: new PostgreSqlStore({
       pgPromise: db,
       ttl: 2 * 60 * 60, //Hours, minute, seconds
    }),
 };
 app.use(session(sessionConfig));

Is there anything I'm doing wrong, or is there something else I should be looking at to find the cause of this behavior?

Answer 1

store: new PostgreSqlStore({
   pgPromise: db,
   ttl: 2 * 60 * 60, //Hours, minute, seconds
})

I think your PostgreSQL store ttl property should be equivalent to maxAge property of session config
