Session lifetime in node.js with express and MongoDB

Your question is a little vague but from what i can gather you wan't to set the expiration period for the session:

you can use maxAge like so:

app.use(express.cookieParser());app.use(express.session({    secret  : "Stays my secret",    maxAge  : new Date(Date.now() + 3600000), //1 Hour    expires : new Date(Date.now() + 3600000), //1 Hour    store   : new MongoStore({ db: 'myDB' })}));

expires value is required for new versions of express where as maxAge is for older versions, you should only need expires though.

@RobertPitt edit your answer.Cookie (session) object looks like:

{ "cookie":"originalMaxAge":null,"expires":null,"httpOnly":true,"path":"/"}, "your_var_1":"value 1", "your_var_2":"value 2", ...}

Argument for express.session should look like this (it's in documentation):

app.use(express.session({    secret  : "Stays my secret",    cookie: {        maxAge  : new Date(Date.now() + 3600000), //1 Hour        expires : new Date(Date.now() + 3600000), //1 Hour    },    store   : new MongoStore({ db: 'myDB' })}));

Moreover this:

maxAge  : new Date(Date.now() + 3600000), //1 Hour

will cause that every cookie (here also session) will be expired automatically one hour after server start
