Hello, I have few questions regarding express-session middleware. Here is my code:
app.use(
session({
secret: 'keyboard cat',
saveUninitialized: false,
resave: false,
})
);
app.get('/', (req, res) => {
console.log(req.sessionID);
res.render('index');
});
I noticed that everytime I’m hitting the '/'
route the server is console.logging another session ID each time. However when I’m attaching something to req.session like this:
req.session.dbId = user.id;
Server is console.logging the same session ID after each request. Also after checking Appliaction info in Chrome Dev Tools I noticed that cookie is created (after attaching this dbId
to req.session
). So here are my questions:
- Why cookie was not set at the beggining when I didn’t attach anything to
req.session
? - Why attaching something to
req.session
cause express-session to create cookie?
