How to send cookies to client from node/express server? - node.js

Question

I am having the hardest time sending cookies from my nodejs server to my browser. Below is my index.js (server side) code:
app.use(express.json());
app.use(express.urlencoded({ extended: true }))
app.use(
cors({
origin: "http://localhost:3000",
methods: "GET,HEAD,PUT,PATCH,POST,DELETE",
credentials: true
})
);
let port = process.env.PORT;
if (port == null || port == "") {
port = 5000;
}
mongoose.connect(process.env.ATLAS_URI).then(console.log("MongoDB Connection Success")).catch(err => console.log("MongoDB Connection Failed" + err))
app.use(session({
secret: 'random secret',
resave: false,
saveUninitialized: false,
// store: MongoStore.create({ mongoUrl: process.env.ATLAS_URI }),
cookie: {
expires: 7 * 24 * 6 * 60 * 1000,
secure: false,
},
}));
app.use(cookieParser())
app.use(passport.initialize())
app.use(passport.session())
app.use("/auth", auth)
I know a cookie is being created when i authenticate a user because if i uncomment out the store in app.use(session({...}) i see session IDs and cookies in my mongodb. But how can I send it to the browser?

Answer 1

try this config for the session options.
my version of express-session is "^1.17.2"
app.use(session({
name: 'random name',
resave: false,
saveUninitialized: false,
secret: 'random secret',
store: MongoStore.create({
mongoUrl: config.DatabaseUrl,
ttl: 14 * 24 * 60 * 60 // = 14 days. Default
})
}));
if this config does not work, check your passport authenticate function that set session true like the below example :
passport.authenticate('local.register', {session: true}, (err, user): void => {
// When res has an Error
if (err) return res.redirect('/auth/register');
return res.redirect('/');
})(req, res);
