Node/Express with connect-redis, how handle session expiry
Using Redis with express-session, you can use the touch() method from express-session to reset the TTL. So if you set a TTL when creating the session, do something like this on the routes where you don't want the session to expire:
api.get("/someRoute/", (req, res) => { req.session.touch(); // Whatever else you need to do res.sendStatus(200);}That will reset the TTL on Redis and prevent the session from expiring assuming the client is still hitting your API - I'm assuming that if the client doesn't interact with your API for long enough, that implies the browser is closed or otherwise finished using your app.
You can specify a ttl while creating the session store.You can find more options in the readme.
app.use(session({ store: new RedisStore(options), secret: 'keyboard cat', ttl : 20 // ttl is in seconds. From the readme.}));
